Technical Field

[0001] This invention generally relates to an electric transportation climate control system. More specifically, this invention relates to the electrical control of a transportation climate control system. Background Technology

[0002] Climate control systems for transport are typically used to control environmental conditions (such as temperature, humidity, and air quality) within transport units (e.g., containers, trucks, vans, or other similar transport units). Climate-controlled transport units are commonly used to transport perishable goods, such as agricultural products, frozen foods, and meat products. They are also used to transport passengers between different locations.

[0003] A transport climate control system includes a climate control unit (“CCU”) attached to the transport unit to control one or more environmental conditions (e.g., temperature, humidity, atmosphere, etc.) in a specific space (e.g., cargo space, passenger space, etc.) (often referred to as the “interior space”). The CCU may include multiple components that require electricity to operate (e.g., compressors, one or more fans or blowers, controllers, solenoid valves, etc.). Summary of the Invention

[0020] In the following detailed description, reference will be made to the accompanying drawings, which illustrate embodiments in which the invention may be practiced. These embodiments are described in sufficient detail to enable those skilled in the art to practice the claims, and it should be understood that other embodiments may be utilized without departing from the spirit and scope of the claims. Therefore, the following detailed description and drawings should not be considered limiting.

[0021] Different types of goods / commodities may require specific environmental conditions when stored within a transport unit. For example, perishable goods may need to be stored within a specific temperature range to prevent spoilage, and liquid goods may need to be kept at temperatures above their freezing point. Furthermore, goods containing electronic components may need to be kept in environments with low moisture content to avoid damage to these components. Passengers traveling within the transport unit may require a climate-controlled space with specific environmental conditions to ensure their comfort during their journey. For example, the climate-controlled space accommodating passengers should be at a temperature at which passengers are typically comfortable. The transport climate control system is configured to blow conditioned air into the climate-controlled space of the transport unit to maintain the air within the climate-controlled space under the required environmental conditions.

[0022] The embodiments described herein relate to an electric transportation climate control system. More specifically, the embodiments described herein relate to the electrical control of a transportation climate control system.

[0023] Specifically, the embodiments described herein generally relate to climate-controlled transport units, transport climate control systems, and climate control units, wherein the climate control unit includes an internal rechargeable power source (e.g., a battery pack) configured as an internal power source. In some embodiments, the internal rechargeable power source is configured to provide sufficient power to power the climate control loop (e.g., compressor, expansion device, sensor, controller, etc.) of the climate control unit to climate-regulate the climate-controlled space of the transport unit. For example, the internal rechargeable power source is capable of providing sufficient power to meet the needs of the climate control loop, thereby continuing to provide climate regulation of the climate-controlled space. For example, this sufficient power provides both a sufficient amount of power to meet the needs and a sufficient amount of power for a period of time. The internal rechargeable power source can advantageously ensure that the climate control unit can continue to operate the transport climate control system stably when external power is unavailable. For example, this can ensure that when the climate control unit suddenly stops receiving external power, the battery pack can provide power and ensure continuous climate regulation to reach a destination with available external power and / or to a destination where goods in the climate-regulated space can be unloaded to different climate-regulated spaces (e.g., unloaded to different climate-controlled transport units, climate-regulated storage facilities, etc.).

[0024] Figure 1AAn embodiment of a climate-controlled van 100 is shown, comprising a climate-controlled space 105 for carrying cargo and a transport climate control system 110 for providing climate control within the climate-controlled space 105. The transport climate control system 110 includes a climate control unit (CCU) 115 mounted on the roof 120 of the van 100. Among other components, the transport climate control system 110 may include a climate control loop 118 connected to, for example, a compressor, condenser, evaporator, and expansion devices (e.g., expansion valves, expansion orifices, etc.) to provide climate control within the climate-controlled space 105.

[0025] CCU 115 includes a rechargeable power supply (“REPS”) 109A (e.g., a battery pack), which is the power source for operating the transport climate control system 110. The transport climate control system 110 is an electrical system that does not include an engine. REPS 109A can provide power to operate CCU 115 to provide climate regulation for the climate-controlled space 105 for a considerable period of time. The characteristics of its CCU (e.g., CCU 115) will be discussed in more detail below (e.g., see references). Figure 2-4 ).

[0026] The climate-controlled van 100 may include a battery 109B, which is a power source for operating the climate-controlled van 100 and / or providing supplemental power to the transportation climate control system 110. In one embodiment, the climate-controlled van 100 may also include an engine (not shown) as a power source. The climate-controlled van 100 may be a hybrid vehicle using a combination of battery power and engine power, or an electric vehicle without an engine. In one embodiment, the climate-controlled van 100 is an electric vehicle without an engine, and the battery 109B provides power for operating the climate-controlled van 100.

[0027] The transport climate control system 110 also includes a programmable climate controller 125 and one or more sensors (not shown) configured to measure one or more parameters of the transport climate control system 110 (e.g., ambient temperature outside the van 100, ambient humidity outside the van 100, compressor intake pressure, compressor exhaust pressure, supply air temperature of air supplied from the CCU 115 to the climate-controlled space 105, return air temperature of air returning from the climate-controlled space 105 to the CCU 115, humidity within the climate-controlled space 105, temperature of the REPS 109A, etc.) and transmit the parameter data to the climate controller 125. The climate controller 125 is configured to control the operation of the transport climate control system 110, which includes components of the climate control loop 118. The climate controller 125 may include a single integrated control unit 126, or a distributed network that may include climate controller elements 126, 127. The number of distributed control elements in a given network may depend on the specific application of the principles described herein.

[0028] Figure 1B An embodiment of a climate-controlled inline truck 130 is shown, which includes a climate-controlled space 131 for carrying cargo and a transport climate control system 132. The transport climate control system 132 includes a climate control unit (CCU) 133 mounted to the front wall 134 of the climate-controlled space 131. Among other components, the CCU 133 may include a climate control loop 138 connected to, for example, a compressor, condenser, expander, and evaporator to provide climate control within the climate-controlled space 131.

[0029] CCU 133 includes REPS 139A (e.g., a battery pack), which is the power source for operating the transport climate control system 132. The transport climate control system 132 is an electrical system that does not include an engine. REPS 139A can provide power to operate CCU 115 to provide climate regulation for the climate-controlled space 131 for a considerable period of time. The characteristics of the CCU (e.g., CCU 133) will be discussed in more detail below (e.g., see references). Figure 2-4 ).

[0030] The climate-controlled inline truck 130 may include a battery 139B, which is a power source for operating the climate-controlled inline truck 130 and / or providing supplemental power to the transportation climate control system 132. In one embodiment, the climate-controlled inline truck 130 may also include an engine (not shown) as a power source. The climate-controlled inline truck 130 may be a hybrid vehicle using a combination of battery power and engine power, or an electric vehicle without an engine. In one embodiment, the climate-controlled inline truck 130 is an electric vehicle without an engine, and the battery 139B provides power for operating the climate-controlled inline truck 130.

[0031] The transportation climate control system 132 also includes a programmable climate controller 135 and one or more sensors (not shown) configured to measure one or more parameters of the transportation climate control system 132 (e.g., ambient temperature outside the truck 130, ambient humidity outside the truck 130, compressor intake pressure, compressor exhaust pressure, supply air temperature of air supplied from the CCU 133 to the climate-controlled space 131, return air temperature of air returning from the climate-controlled space 131 to the CCU 133, humidity within the climate-controlled space 131, temperature of the REPS 139A, etc.) and transmit the parameter data to the climate controller 135. The climate controller 135 is configured to control the operation of the transportation climate control system 132, which includes components of the climate control loop 138. The climate controller 135 may include a single integrated control unit 136, or a distributed network that may include climate controller elements 136, 137. The number of distributed control elements in a given network may depend on the specific application of the principles described herein.

[0032] Figure 1C An embodiment of a climate-controlled transport unit 140 attached to a tractor unit 142 is shown. The climate-controlled transport unit 140 includes a transport climate control system 150 for a transport unit 144. The tractor unit 142 is attached to and configured to tow the transport unit 144. Figure 1C The transport unit 144 shown is a trailer.

[0033] The transport climate control system 150 includes a climate control unit (CCU) 152 that provides environmental control (e.g., temperature, humidity, air quality, etc.) within the climate-controlled space 146 of the transport unit 144. The CCU 152 is located on the front wall 148A of the transport unit 144. In other embodiments, it will be understood that the CCU 152 may be located, for example, on the roof 148B of the transport unit 144 or on another wall. The CCU 152 includes a climate control loop 154 ​​that connects, for example, a compressor, condenser, evaporator, and expander, to provide conditioned air within the climate-controlled space 146.

[0034] CCU 152 includes REPS 159A (e.g., a battery pack), which is the power source for operating the transport climate control system 150. The transport climate control system 150 is an electrical system that does not include an engine. REPS 159A can provide power to operate CCU 152 to provide climate regulation for the climate-controlled space 146 for a considerable period of time. The characteristics of the CCU (e.g., CCU 152) will be discussed in more detail below (e.g., see references). Figure 2-4 ).

[0035] The tractor unit 142 may include a battery 149B, which serves as a power source for operating the tractor unit 142. In one embodiment, the tractor unit 142 may also include an engine (not shown) as a power source. The tractor unit 142 may be a hybrid vehicle using a combination of battery power and engine power (e.g., an internal combustion engine, a hydrogen internal combustion engine, etc.), or a non-internal combustion engine vehicle without an engine (e.g., a battery-powered electric vehicle, a hydrogen fuel cell-powered vehicle, etc.). In one embodiment, the tractor unit 142 is a non-internal combustion engine vehicle without an engine, and the battery 159B provides power for operating the tractor unit 142.

[0036] The transport climate control system 150 also includes a programmable climate controller 156 and one or more sensors (not shown) configured to measure one or more parameters of the transport climate control system 150 (e.g., ambient temperature outside the transport unit 144, ambient humidity outside the transport unit 144, compressor suction pressure, compressor discharge pressure, supply air temperature of air supplied from the CCU 152 to the climate-controlled space 146, return air temperature of air returning from the climate-controlled space 146 to the CCU 152, humidity within the climate-controlled space 146, etc.) and transmit the parameter data to the climate controller 156. The climate controller 156 is configured to control the operation of the transport climate control system 150, which includes components of a climate control loop 154. The climate controller 156 may include a single integrated control unit 157, or a distributed network that may include climate controller elements 157, 158. The number of distributed control elements in a given network may depend on the specific application of the principles described herein.

[0037] In one embodiment, the transport climate control system 150 may be a multi-zone transport climate control system (MTCS). The MTCS includes a control unit (CCU) 152 and multiple remote units (not shown) that provide environmental control (e.g., temperature, humidity, air quality, etc.) within a climate-controlled space 146 of the transport unit 144. The climate-controlled space 146 may be divided into multiple zones separated by walls, curtains, etc. (not shown). The CCU 152 may operate as a host unit and provide climate control within a first zone (not shown) of the climate-controlled space 146, and corresponding remote units may provide climate control within each other corresponding zone of the climate-controlled space 146 (e.g., a second zone, a third zone, etc.). The CCU 152 supplies a working fluid (e.g., refrigerant) to a heat exchanger (e.g., an evaporator) in each operating remote unit, which regulates (e.g., heats / cools) the air in its respective zone.

[0038] In the illustrated embodiment, transport unit 144 is a ground transport unit configured for traction along the ground. It should be understood that in another embodiment, transport unit 144 may be a maritime transport unit (e.g., a refrigerated container, shipping container, etc.) configured for transport by sea (e.g., on a ship). In some embodiments, the maritime transport container may be a modular container configured for transport by sea and placed on a wheeled frame for traction along the ground (e.g., towed by a tractor 142).

[0039] For example, in conventional transport climate control systems used for transport units (e.g., land transport units, maritime transport units, etc.), the transport climate control system typically includes an engine (e.g., an internal combustion engine) to independently generate power to operate the transport climate control system and thus provide climate regulation. In contrast to conventional transport climate control systems, in one embodiment, the transport climate control system 150 does not include an engine, while utilizing REPS 159A to independently ensure the availability of electricity to operate the transport climate control system 150. This can advantageously reduce weight and can advantageously reduce / eliminate particulate matter and greenhouse gas emissions, for example.

[0040] Figure 1D This is a perspective view of a vehicle 185 including a transport climate control system 187 according to one embodiment. Vehicle 185 is a public transport bus that can transport passengers (not shown) to one or more destinations. In other embodiments, vehicle 185 may be a school bus, railcar, subway, or other commercial vehicle carrying passengers. Vehicle 185 includes a climate-controlled space 189 (e.g., a passenger compartment) that can accommodate multiple passengers. Vehicle 185 includes a door 190 located on one side of vehicle 185. Figure 1DIn the embodiment shown, the first door 190 is located near the front of the vehicle 185, and the second door 190 is positioned towards the rear of the vehicle 185. Each door 190 is movable between an open position and a closed position to selectively allow access to the climate-controlled space 189.

[0041] The transport climate control system 187 includes a climate control unit (CCU) 192 attached to the roof 194 of the vehicle 185. The CCU 192 includes a climate control loop 193 that connects, for example, a compressor, condenser, evaporator, and expander, to provide conditioned air within the climate-controlled space 189.

[0042] CCU 170 includes REPS 198A (e.g., a battery pack), which is the power source for operating the transportation climate control system 187. In one embodiment, the transportation climate control system 187 is an electrical system that does not include an engine. REPS 198A can provide power to operate CCU 170 to provide climate regulation for the climate-controlled space 189 for a considerable period of time. In one example, REPS 198A can ensure that climate regulation of the climate-controlled space 189 is maintained for passengers during the period of vehicle 185 failure (e.g., until a different work vehicle arrives to provide transportation). The characteristics of the CCU (e.g., CCU 170) will be discussed in more detail below (e.g., refer to...). Figure 2-4 ).

[0043] Vehicle 185 may include a battery 198B, which is a power source for operating vehicle 185. In one embodiment, vehicle 185 may also include an engine (not shown) as a power source. Vehicle 185 may be a hybrid vehicle using a combination of battery power and engine power, or an electric vehicle without an engine. In one embodiment, vehicle 185 is an electric vehicle without an engine, and battery 198B provides power for operating vehicle 185.

[0044] The transportation climate control system 187 also includes a programmable climate controller 195 and one or more sensors (not shown) configured to measure one or more parameters of the transportation climate control system 187 (e.g., ambient temperature outside the vehicle 185, ambient temperature inside the climate-controlled space 189, ambient humidity outside the vehicle 185, ambient humidity inside the climate-controlled space 189, temperature of the REPS 198A, etc.) and transmit the parameter data to the climate controller 195. The climate controller 195 is configured to control the operation of the transportation climate control system 187, which includes components of the climate control loop 172. The climate controller 195 may include a single integrated control unit 196, or a distributed network that may include climate controller elements 196, 197. The number of distributed control elements in a given network may depend on the specific application of the principles described herein.

[0045] It should be understood that the embodiments described herein are not limited to those described herein. Figure 1A-1D The exemplary climate-controlled transport unit in the example is not applicable to any type of climate-controlled transport unit with different types of transport units, such as trucks, containers (such as containers on flatbeds, intermodal containers, sea containers, etc.), box trucks, semi-trailer tractors, buses or other similar transport units.

[0046] Figure 2 This is a front view of one embodiment of the CCU 202 of the transport climate control system 200. The transport climate control system 200 is configured to regulate the climate-controlled space of the transport unit. The CCU 202 may be... Figure 1A The CCU 115 in the transport climate control system 110 of the climate-controlled van 100 Figure 1B The CCU 133 in the transport climate control system 132 of the climate-controlled straight truck 130 Figure 1C The CCU 152 in the transport climate control system 150 of the climate-controlled transport unit 140, or Figure 1D The CCU 192 in the transport climate control system 187 of vehicle 185. Specifically, Figure 2 The CCU 202 shown is with Figure 1C The CCU 152 of the Central Climate Control Transport Unit 140 is of the same type. It should be understood that, in other embodiments, the features of the CCU 202 discussed herein can be similarly applied. Figure 1A , 1B And CCUs in other types of regulated transport vehicles in 1D.

[0047] CCU 202 includes a housing 204. The housing 204 contains components of the CCU 202. The components of the CCU 202 are located within an internal space 210 of the CCU 202. The internal space 210 of the CCU 202 is defined by the housing 204. The internal space 210 includes a first compartment 212 and a second compartment 214. Each of the compartments 212 and 214 is defined by the housing 204. The first compartment 212 is a lower compartment, and the second compartment 214 is an upper compartment.

[0048] like Figure 2As shown, the outer casing 204 is formed by a plurality of outer panels 205A, 205B, 205C, 205D, 205E, 205F, and 205G. For example, compartments 212 and 214 are each defined by the outer casing panels 205A, 205B, 205C, 205D, 205E, 205F, and 205G. In the illustrated embodiment, the outer casing 204 includes a front outer panel 205A, a side outer panel 205B, a top outer panel 205C, and a bottom outer panel 205D. The outer casing 204 may also include a grille 206 to allow air to flow into / through the CCU 202 (e.g., the grille 206 of the outer casing 204 allows ambient air to flow into the interior space 210 of the CCU 202). The housing 204 may also include an outlet grille (not shown) in the housing 204 (e.g., at the top, bottom, side, etc. of the CCU 202) for discharging air from the CCU 202 (e.g., discharging air heated in the condenser of the CCU 202).

[0049] Figure 3 This is a front perspective view of one embodiment of the CCU 202 with the housing 204 omitted. The CCU 202 is configured to be attached to a transport unit (e.g., Figure 1C The transport unit 144 in the middle). The CCU 202 has an exhaust side 240 (e.g., rear side) for discharging regulated air (in the transport unit 144). Figure 3 (This is usually obscured in the view). The discharge side 260 is attached to the transport unit. For example, the CCU202 has a support frame 262 fixed to the transport unit (e.g., the outer wall of the transport unit). Figure 1C (Front wall 148A of the transport unit 144). The outer casing 204 can be attached to the support frame 262.

[0050] CCU 202 includes a climate control loop 230. Climate control loop 230 includes a compressor 232, a condenser 234, an expander 236, and an evaporator 238 (in...). Figure 3 In the view, what is obscured is indicated by a dashed line. Figure 3The dashed lines indicate portions (e.g., pipe / hose sections) extending to and from compressor 232 of the climate control loop. Climate control loop 230 operates based on known vapor compression system principles. Climate control loop 230 is configured to operate in cooling mode to provide conditioned air (e.g., cooled air) to a climate-controlled space. Typically, in cooling mode, the flow of the working fluid (e.g., refrigerant) in climate control loop 230 is from compressor 232 to condenser 234, from condenser 234 to expansion unit 236, from expansion unit 236 to evaporator 238, and from evaporator 238 back to compressor 232. The working fluid is compressed by compressor 232, cooled and at least partially condensed in condenser 234 (e.g., by ambient air), expanded by expansion unit 236 (which also cools the working fluid), and then heated and evaporated in evaporator 238. The relatively cool expanding working fluid absorbs heat from the air flowing through the evaporator 238, thereby cooling the air. It should be understood that the "working fluid" as used herein can be one or more types of refrigerants, which can be mixed with one or more lubricants and / or refrigerant additives (e.g., stabilizers, defoamers, tracers, etc.) to form the working fluid flowing through the climate control loop. The cooled air then flows from the evaporator 238 to the climate-regulated space.

[0051] Compressor 232 is located in the first compartment 212. Condenser 234 and evaporator 238 are located in the second compartment 214. CCU 202 may include a partition 216 that provides an airflow path through evaporator 238 (e.g., forming a path from the climate-controlled space through evaporator 238 back to the climate-controlled space). Partition 216 is located in the second compartment 214. Figure 3 As shown, partition 216 can separate the second compartment 214. In the illustrated embodiment, CCU 202 does not include an engine (e.g., an internal combustion engine, an engine with a generator, etc.). In one embodiment, the transport climate control system 200 does not include an engine (e.g., a climate-controlled transport unit does not contain an engine).

[0052] CCU 202 includes a REPS250 (e.g., a battery pack) located within housing 204. Figure 2(As shown). REPS 250 is located in the internal space 210 of housing 204. REPS 250 is located in the first compartment 212 of CCU 202. The position of REPS 250 within housing 204 can advantageously ensure its protection from external damage (e.g., from roads, or from forklifts or other vehicles moving inside and / or around CCU 202). For example, REPS 250 can be placed far enough from the road that it does not require crash testing (e.g., placed more than 700 mm above the ground), reducing / avoiding gravel impacts, and also avoiding higher ambient temperatures near relatively hot asphalt. REPS 250 is also located outside the regulated space of the transport unit to prevent ice / condensation from accumulating on REPS 250.

[0053] REPS 250 is configured to supply power to CCU 202 (e.g., to the transport climate control system 200 of CCU 202). When external power is unavailable, REPS 250 can provide power to operate CCU 202 (e.g., to operate the transport climate control system 200). External power is power supplied from a source outside of CCU 202. For example, external power is unavailable when the external power source is unavailable (e.g., the external energy is being replaced, substituted, refueled, disconnected, etc.) or when the amount of available external power (from an external power source) is insufficient. In one embodiment, REPS can be configured to provide supplemental power to external power to allow CCU 202 to operate at a higher capacity (e.g., higher cooling capacity, faster cooling rate, faster defrosting rate, etc.) than when using external power intermittently.

[0054] In the illustrated embodiment, the REPS 250 includes a plurality of battery modules 252 electrically connected to each other. Each battery module 252 contains at least one battery cell (not shown). The CCU 202 includes a thermal management system (260). The thermal management system may be referred to as a battery thermal management system (“BTMS”) 260. The BTMS 260 is configured to regulate (e.g., cool and / or heat) the REPS 250. In one embodiment, the BTMS 260 may be configured to cool the REPS 250 using a climate control loop 230. For example, the BTMS 260 may include a coolant loop that circulates coolant through the REPS 250 (e.g., Figure 4(e.g., coolant circuit 342 in the example). In another example, the coolant circuit may be part of climate control circuit 230, where the coolant is part of the working fluid (e.g., expanding working fluid) flowing through REPS 250. In another embodiment, CCU 202 may include a second climate control circuit (not shown) that provides cooling for REPS 250 (e.g., secondary vapor compression circuit, climate control circuit 230 in FIG. 5). In another embodiment, BTMS 260 may be configured for air cooling (e.g., by directing air through CCU 202, or indirectly by air cooling the coolant circulating through REPS 250 in the cooling circuit). In some embodiments, BTMS 260 may be configured to also heat REPS 250 (e.g., during periods of lower ambient temperature). In one embodiment, BTMS 260 may include an electric heater (e.g., Figure 4 The heater 316 (e.g., in the BTMS260) is configured to heat the coolant in the BTMS260 (e.g., heat the coolant). Figure 4 (Coolant in the intermediate coolant circuit 342, etc.). The electrical configuration of the REPS250 is described in more detail below.

[0055] REPS 250 is configured to supply power to operate climate control loop 230, thereby providing climate regulation for the climate-controlled space. Climate control loop 230 is capable of operating in conjunction with REPS 250, and the amount of power provided by REPS 250 is sufficient to meet the electrical load of climate control loop 230. REPS 250 provides current and voltage for operating climate control loop 230. Specifically, the power provided by REPS 250 is used to power compressor 232 of climate control loop 230 (e.g., to power motor 233 of compressor 232). The power supplied to compressor 232 (e.g., to power motor 233 of compressor 232) is used to compress the working fluid (e.g., refrigerant) in climate control loop 230, thereby providing climate regulation. CCU 202 may include one or more electric heaters (e.g., Figure 4 The electric heater 316 (e.g., in the heating mode). The electric heater can be configured to provide defrosting (e.g., defrosting of the evaporator 238), for heating mode, etc. The REPS 250 can also power the heater. Specifically, when operating in heating mode in the CCU 202 and climate control loop 230, the REPS 250 provides power to power the electric heater. In one embodiment, the electric heater may be in the form of a heating rod that operates in heating mode to provide heating to the climate-controlled space.

[0056] In one embodiment, the REPS 250 is configured to provide at least 20 kWh of power for operating the climate control loop 230 to provide climate regulation to a climate-controlled space. In one embodiment, the REPS 250 is configured to provide at least 25 kWh of power for operating the climate control loop 230 to provide climate regulation to a climate-controlled space. In one embodiment, the REPS 250 is configured to provide at least 30 kWh of power for operating the climate control loop 230 to provide climate regulation to a climate-controlled space. In another embodiment, the REPS 250 is configured to provide at least 30 kWh of power for operating the climate control loop 230 to provide climate regulation to a climate-controlled space.

[0057] In one embodiment, REPS 250 is configured to provide sufficient power to operate climate control loop 230 to provide climate regulation to a climate-controlled space for at least two hours. In another embodiment, REPS 250 is configured to provide sufficient power to climate control loop 230 to enable the climate control loop to provide climate regulation to the climate-controlled space for a set period of time (e.g., at least four hours). The power supplied by REPS 250 is sufficient to enable the climate control loop to operate at full capacity in cooling mode. For example, REPS 250 may be configured to supply sufficient power to enable climate control loop 230 to operate at full capacity in cooling mode for a maximum set period of time (e.g., at least one hour). REPS 250 may be configured to supply power throughout the entire charging state of the REPS (e.g., from 100% charge to 1% charge) to power the climate control loop operating at full capacity in cooling mode. For example, REPS 250 is configured to provide sufficient power (voltage and current) to power the climate control loop operating at full capacity in cooling mode, while having at least some power remaining. When the climate control loop 230 is operating at full capacity, the compressor 232 of the climate control loop 230 operates at full power (e.g., at the maximum speed of the compressor 232, at the maximum speed of the motor 233 of the compressor 232, etc.). For example, the REPS 250 supplies sufficient voltage and current to the compressor 232 to allow it to operate at full power. The REPS 250 can also supply sufficient power to power other electrical components in the CCU 202 used to operate and control the climate control loop 230 (e.g., fans, controllers, sensors, electric heaters, etc.).

[0058] Because REPS250 is located within CCU 202, it ensures the continuous and stable operation of the transport climate control system 200 when external power is unavailable. For example, REPS250 allows the transport climate control system 200 to continuously regulate the climate-regulated space for a period of time sufficient to reach a destination with available external power from CCU 202 and / or to unload goods from the climate-regulated space to a destination in a different climate-regulated space (e.g., to a different climate-controlled transport unit, climate-regulated storage facility, etc.).

[0059] Figure 4 This is a schematic diagram of one embodiment of the power system 302 of the CCU 300. The CCU 300 is used to transport a climate control system. For example, in one embodiment, the CCU 300 may be... Figure 2-3 The CCU 202 of the transport climate control system 200. For example, the CCU 300 includes a transport climate control loop 310. Figure 2 Transport Climate Control Loop 230 and REPS 320 (e.g., Figure 2 (REPS250 in the text). Dotted lines indicate electrical connections between different components, and dashed lines indicate fluid connections between different components.

[0060] like Figure 4 As shown, the CCU 300 includes a REPS 320, a power distribution unit 304, and a DC bus 324. The power distribution unit 304 and the DC bus 324 supply power (e.g., DC power) to the electrical load components of the CCU 300. The electrical load components of the CCU 300 are electrically connected to and receive power from the DC bus 324. The power received by the power distribution unit 304 is supplied to the DC bus 324 and then distributed to the electrical load components via the DC bus 324. For example, the electrical load components of the CCU 300 may include, but are not limited to, a compressor motor 312, a climate controller 314, one or more heaters 316 (e.g., for defrosting, for heating mode, etc.), one or more fans 318, and / or a REPS thermal management system 340. The heater 316 may be one or more of a resistance heater, a negative temperature coefficient (NTC) heater, a positive temperature coefficient (PTC) heater, etc., and may be controlled, for example, by a switching element (not shown). In one embodiment, REPS can also provide power to auxiliary electrical components of the transport unit located outside the CCU 300 (e.g., the transport unit's lifting doors, etc.). The compressor motor 312 is the motor of the compressor in the climate control loop 310 (e.g., Figure 3 The compressor 223 in the compressor 223 (motor 233). For example, the climate controller 314 is configured to control the operation of the CCU 220 (e.g., is Figure 1AClimate controller 125 in Figure 1B Climate controller 135 in Figure 1C Climate controller 156 in Figure 1D Climate controllers (e.g., 195).

[0061] In one embodiment, REPS 320 may be a lower voltage REPS. For example, the output voltage of a lower voltage REPS is less than 60 volts (e.g., the output voltage is in the range of less than 60 volts and equal to or greater than 20 volts). In such an embodiment, CCU 300 includes a DC-DC converter 328 that electrically connects REPS 320 to power distribution unit 304. DC-DC converter 328 is configured to convert the voltage of the power flowing between REPS 320 and power distribution unit 304. For example, DC-DC converter 328 converts power supplied from the lower voltage of REPS 320 to a higher voltage of DC bus 324. For example, DC-DC converter 328 converts power supplied from power distribution unit 304 to REPS 320 from a higher voltage (e.g., a higher voltage of DC bus 324) to a lower voltage of REPS 320. The advantage of lower voltage REPS is that it is less hazardous (e.g., classified as non-hazardous) and easier to utilize external sources with different voltages. For example, the advantage of a lower voltage REPS is that it makes maintaining the CCU300 easier, as the lower voltage allows for maintenance without specialized tools and without the higher protection required for maintaining higher voltage systems. In one embodiment, the lower voltage REPS operates over a voltage range of 32V to 55V.

[0062] In another embodiment, REPS 250 can be a higher voltage REPS whose output voltage is the same as the voltage of DC bus 324. For example, the higher voltage REPS has an output voltage equal to or greater than 60 volts. In one example, the output voltage of the higher voltage REPS can be in the range of 60-1500 volts. The higher voltage REPS can have the same output voltage as the voltage of DC bus 324. In this embodiment, the power of REPS 320 can be directly supplied to the power distribution unit 304 (i.e., omitting...). Figure 4 The DC-DC converter 328 shown is an example. Higher voltage REPS can advantageously be electrically coupled to the DC bus 324 without a power converter and supply power more efficiently.

[0063] In another embodiment, REPS 320 may be a higher voltage REPS having an output voltage that partially overlaps with the voltage of DC bus 324 (e.g., the output voltage varies between being equal to and different from the voltage of DC bus 324). In this embodiment, the power of REPS 320 may be directly supplied to the power distribution unit 304 (i.e., omitting components such as...). Figure 4 (The DC-DC converter 328 shown). When the output voltage of the higher voltage REPS is equal to the voltage of the DC bus 324, power flows to the DC bus 324 without being converted by the DC-DC converter 328. When the output voltage of the higher voltage REPS is different from the voltage of the DC bus 324, the DC-DC converter 328 converts the output voltage of the higher voltage REPS (e.g., by buck or boost) to the voltage of the DC bus 324.

[0064] In one embodiment, REPS 320 is a battery module (not shown) comprising multiple electrical connections (e.g., Figure 3 The REPS 320 may include a battery pack (not shown) containing battery modules 252. Each battery module may include a battery module controller (not shown), and the REPS management controller may communicate with the battery module controllers within the REPS. For example, in a higher voltage REPS, the battery modules are connected in series. For example, in a lower voltage REPS, the battery modules are connected in parallel. For example, the battery modules may be connected in both parallel and series. The REPS 320 may include multiple groups of battery modules, wherein the battery modules in each group are arranged in parallel, and multiple groups are arranged in series with each other. For example, in... Figure 3 In this embodiment, the REPS 320 includes four groups of batteries connected in series, with each group comprising two batteries. In one embodiment, the REPS 320 is configured to have a number of battery module groups to provide the required current (e.g., the required current to operate the CCU 330 at maximum regulation) and a number of batteries in each group to provide the required voltage.

[0065] The CCU 300 is configured to charge the REPS 320 using external power. The external power is supplied from outside the CCU 300 (e.g., from a power source outside the CCU 300's housing). The external power is received by a power distribution unit 304, which supplies the external power to the REPS 320. The power distribution unit 304 can be configured to receive external power from one or more external power sources discussed below.

[0066] External power may be utility power supplied by external power source 390. Utility power may be (but is not limited to) grid power (e.g., power from the power grid), facility power (e.g., power generated at the facility where the climate-controlled transport unit is parked), etc. Power system 302 may include a DC input 370 (e.g., a DC plug / socket) electrically connected to distribution unit 304 for receiving DC power from external power source 390. Power system 302 may include an AC input 374 (e.g., an AC plug / socket) for receiving AC power from external power source 390 and an on-board battery charger 372 with an AC-DC converter 373. The AC-DC converter 373 converts the AC power supplied from external power source 390 into DC power received by distribution unit 304. It should be understood that external power source 390 may also include typical electrical components (e.g., DC electric vehicle power supply equipment (“EVSE”), AC EVSE, etc.) for providing charging / operating power to electric vehicles and / or CCUs.

[0067] External power can be supplied by generator 378. Generator 378 can be the alternator and engine of the CCU 300 vehicle (e.g., Figure 1A 100 climate-controlled vans Figure 1B Climate-controlled straight truck 130 Figure 1C Medium tractor 142 Figure 1D The alternator and engine of vehicle 185, etc.). Generator 378 can be connected to an attached tractor (e.g., Figure 1C An alternator 378 is an AC generator that receives mechanical power from the engine of a tractor unit 142 (e.g., a tractor unit 142). For example, the power output of the generator 378 may be from an ePTO (electric power take-off unit, “ePTO”) (not shown) supplied from the attached tractor unit. External power is supplied from the generator 378 to the distribution unit 304 via an AC-DC converter 376. The AC-DC converter 376 converts the AC power supplied by the generator into DC power received by the distribution unit 304.

[0068] External power can be supplied by an external energy storage system 380. For example, the external energy storage system 380 can be an external battery, fuel cell, etc. The external energy storage system 380 can be located on the transport unit equipped with the CCU 300, or in a tractor that tows the transport unit regulated by the CCU 300 (e.g., Figure 1C (e.g., tractor 142).

[0069] An external battery is a battery located outside the CCU 300 (e.g., outside the housing of the CCU 300). For example, an external battery may be located on / in the climate-controlled transport unit of the CCU 300, or as the battery of a tractor that tows a transport unit regulated by the CCU.

[0070] External power can be supplied by an external energy regeneration source within the climate-controlled transport unit of the CCU 300. For example, energy regeneration source 382 may include solar panels, shaft generators, etc.

[0071] The thermal management system 340 is configured to cool the REPS 320. In some embodiments, the REPS thermal management system 340 may also be configured to provide heating to the REPS 320. For example, the REPS thermal management system 340 is configured to maintain the temperature of the REPS 250 within a predetermined range. The REPS thermal management system 340 circulates battery coolant through the REPS 320 to cool the REPS 320. In one embodiment, the thermal management system 340 may include a heater (e.g., Figure 6 The heater 416 in the middle, and the thermal management system 340 can be configured to heat the REPS 320 (e.g., in heating mode).

[0072] like Figure 4 As shown, the REPS thermal management system 340 may include an REPS coolant circuit 342 containing REPS coolant, and the REPS coolant circuit 342 is configured to circulate coolant (i.e., cooled or heated coolant) through the REPS 320 to cool or heat the REPS 320. In one example, the REPS 320 may include one or more cooling plates or channels (e.g., on a battery module mounted to the REPS 320), through which coolant can flow to cool and heat the REPS 320.

[0073] Figure 5A According to one embodiment Figure 4 A schematic diagram of the power system 302 of the CCU 300 operating in external power mode. In external power mode, external power is supplied to the distribution unit 304 of the CCU 300. In the illustrated embodiment, the external power is provided by an external power source 390. It should be understood that in other embodiments, the external power may be provided by a source or combination of sources different from the external power source 390 (e.g., from one or more of the external power source 390, generator 378, external energy storage system 380, and external energy regeneration source 382).

[0074] like Figure 5AAs shown, the power distribution unit 304 supplies external power to the DC bus 324 and to the REPS 320 via a DC-DC converter 328. When the external power is different from the charging voltage of the REPS 320, the DC-DC converter 328 converts the external power to the charging voltage and supplies the converted external power to the REPS 320. When the voltage of the external power is at the charging voltage of the REPS 320, power can be supplied from the power distribution unit 304 to the REPS 320 without voltage conversion by the DC-DC converter 328. In this embodiment, the PDU 304 prioritizes powering the DC bus 324 and only uses excess power from an external power source (e.g., 390) to charge the REPS 320.

[0075] Figure 5B According to one embodiment Figure 4 A schematic diagram of the power system 302 of the CCU 300 operating in internal power mode. In internal power mode, the REPS 320 provides sufficient power to the DC bus 324 to power the CCU 300. Specifically, the REPS 320 is capable of supplying power with sufficient current and voltage to operate the CCU and provide the required amount of climate-regulating current, as described herein. The DC-DC converter 328 converts the voltage of the power output from the REPS 320 to the voltage of the DC bus 324. The DC-DC converter 328 can also control the amount of electrical force (i.e., the amount of current and voltage) discharged from the DC-DC converter to the power distribution unit to achieve the amount required to operate the CCU 330.

[0076] For example, when the output voltage of REPS 320 is equal to the voltage of DC bus 324, power can be supplied from REPS 320 via the power distribution unit and DC-DC converter 328 (where the DC-DC converter does not perform voltage conversion). For example, when the output voltage of REPS 320 is less than the voltage of DC bus 324, power can be supplied from REPS 320 via the power distribution unit and DC-DC converter 328, where the DC-DC converter converts the power from the REPS output voltage to a higher voltage of DC bus 324. For example, when the output voltage of REPS 320 is greater than the voltage of DC bus 324 (e.g., a lower voltage for low-voltage regulation mode, etc.), power can be supplied from REPS 320 via the power distribution unit and DC-DC converter 328, where the DC-DC converter converts the power from the output voltage to a lower voltage of DC bus 324.

[0077] Figure 6 This is a schematic diagram of one embodiment of a REPS thermal management system 400 for regulating REPS 405. The REPS thermal management system 400 and REPS 405 are used in a CCU. For example, Figure 6The REPS thermal management system 400 and REPS 405 in the text can be respectively Figure 4 The REPS thermal management system 340 and REPS 320 of the CCU 300.

[0078] like Figure 6 As shown, the thermal management system 400 includes a REPS coolant circuit 410 and a climate control circuit 450. The REPS cooling circuit 410 includes a heat exchanger 412, a pump 414, and REPS 405. The climate control circuit 450 includes a compressor 452, a condenser 454, an expansion device (e.g., an expansion valve, an expansion orifice, etc.), and the heat exchanger 412. The climate control circuit 450 operates according to the known principles of vapor compression systems. In cooling mode, a relatively cold working fluid (e.g., containing refrigerant) in the climate control circuit 450 flows from the expansion device 456 to and through the heat exchanger 412, cooling the coolant flowing through the heat exchanger 412 in the REPS cooling circuit 410. The cooled coolant in the REPS cooling circuit 410 then flows to and through the REPS 405, thereby cooling the REPS 405. For example, the condenser 454 may utilize ambient air to cool the working fluid in the climate control circuit 450.

[0079] like Figure 6 As shown, the REPS cooling circuit 410 may include a heater. In heating mode, the coolant in the REPS cooling circuit 410 is heated as it flows through the heater 416, and then the heated coolant is directed to flow through the REPS 405 to heat the REPS 405. In heating mode, the climate control circuit 450 may be inactive.

[0080] exist Figure 6 In the illustrated embodiment, climate control loop 450 is connected to the main climate control loop in the CCU (e.g., Figure 3 Transport climate control loop 230 in Figure 4 The transport climate control loop 310 is a different climate control loop. In another embodiment, the climate control loop 450 can be the main climate control loop. In such an embodiment, Figure 6 The climate control loop 350 also includes an evaporator (not shown) (e.g., Figure 3The evaporator 238 is located downstream of the expansion unit 456 and upstream of the compressor 452, and is connected in series or parallel with the heat exchanger 412. For example, in a parallel configuration, a first portion of the working fluid may flow through the heat exchanger 412 to cool the coolant in the coolant circuit 410, and a second portion of the working fluid may flow through the evaporator. The climate control circuit 450 may include one or more valves (not shown) and / or a second expansion valve (not shown) (e.g., in parallel with the expansion unit 456) to control the flow rate of the working fluid directed through the heat exchanger 412.

[0081] In some embodiments, the working fluid in the climate control loop 450 may also flow directly through the REPS 405 (i.e., without the coolant loop 410). For example... Figure 6 The REPS 405 can be installed in the climate control loop 450, replacing the heat exchanger 412.

[0082] Figure 7 This is a front view of one embodiment of the CCU 502 of the transportation climate control system 500. The transportation climate control system 500 is configured to regulate the climate-controlled space of the transportation unit. The CCU 502 may be... Figure 1A The CCU 115 in the transport climate control system 110 of the climate-controlled van 100 Figure 1B The CCU 133 in the transport climate control system 132 of the climate-controlled straight truck 130 Figure 1C The CCU 152 in the transport climate control system 150 of the climate-controlled transport unit 140, or Figure 1D The CCU 192 in the transport climate control system 187 of vehicle 185. Specifically, Figure 7 The CCU 502 shown is a CCU installed in a climate-controlled transport unit, similar to... Figure 1C The CCU 152 of the climate-controlled transport unit 140. It should be understood that, in other embodiments, the features of the CCU 502 discussed herein can be similarly applied. Figure 1A , 1B And CCUs in other types of regulated transport vehicles in 1D.

[0083] CCU 502 includes a housing 504. Housing 504 contains the components of CCU 502. The components of CCU 502 are located within the internal space 510 of CCU 502. Figure 7As shown, the outer casing 504 is formed by a plurality of outer panels 505A, 505B, 505C, 505D, 505E, 505F, and 505G. For example, compartments 512, 514, and 516 are each defined by panels 505A, 505B, 505C, 505D, 505E, 505F, and 505G of the outer casing 504. In the illustrated embodiment, the outer casing 504 includes a front outer panel 505A, a side outer panel 505B, a top outer panel 505C, and a bottom outer panel 505D. The outer casing 504 may also include grilles 506A and 506B to allow air to flow into / through the CCU 502 (e.g., grilles 506 of the outer casing 504 allow ambient air to flow into the interior space 510 of the CCU 502). The housing 504 may also include an outlet grille (not shown) in the housing 504 (e.g., at the top, bottom, side, etc. of the CCU 502) for discharging air from the CCU 502 (e.g., discharging air heated in the condenser of the CCU 502).

[0084] The internal space 510 of the CCU 502 is defined by the outer shell 504. The internal space 510 includes a first compartment 512, a second compartment 514, and a third compartment 516. Each of compartments 512, 514, and 516 is defined by the outer shell 504. The first compartment 512 is a lower compartment, the second compartment 514 is an upper compartment, and the third compartment 516... Figure 7 In the diagram, short dashed lines are used to indicate internal features that are obscured by the outer housing 504 (e.g., contained within the housing 504), and dotted dashed lines are used to indicate fluid flow between different components.

[0085] like Figure 7 As shown, the first compartment 512 is spaced apart from the second and third compartments 514, 516. The interior space 510 includes a passage 518 defined by the housing 504 that connects the first compartment 512 to the second and third compartments 514, 516 (e.g., the passage 518 directly connects the first compartment 512 to the third compartment 516).

[0086] CCU 502 typically includes and Figure 3 CCU 202 and / or Figure 4-5B The CCU 300 is a component similar to those discussed in the previous discussion. For example, with... Figure 3Similar to CCU 202, CCU 502 includes a climate control loop 530 disposed within a housing 504. This loop includes a compressor 532, a condenser 534, an expander 536, and an evaporator 538 in fluid connection, as well as a REPS 550 disposed within the housing 504. The compressor 532, condenser 534, expander 536, and evaporator 538 are located in second and third compartments 514 and 516, respectively. For example, the condenser 534 and evaporator 538 are located in the second compartment 514. For example, the compressor 532 is located in the third compartment 516.

[0087] The REPS 550 is disposed in the first compartment 512. The housing 504 may include a grille 506B located on the first compartment 512. The REPS 550 may include one or more fans 558 to circulate ambient air through the first compartment 512, thereby providing air cooling to the REPS 550. In one embodiment, the REPS 550 may include a thermal management system for climate-regulating (e.g., heating and / or cooling) the REPS 550. Figure 3 Thermal management system 260 Figure 4-5B Thermal management system 340 Figure 6 The thermal management system 400 may include a coolant circuit (e.g., Figure 4 Coolant circuit 342 in the middle Figure 6 The coolant circuit 410 in the middle), and / or the second climate control circuit (e.g., Figure 6 (Climate control loop 450 in the first compartment). In such an embodiment, the coolant loop and the second climate control loop may be located in the first compartment 512.
