Description

Technical Field

[0001] The embodiments described herein relate to energy management for systems used in transportation. More specifically, the embodiments described herein relate to a generator for providing energy or charging devices and systems associated with transportation components. Background Technology

[0002] Transportation climate control systems are typically used to control one or more environmental conditions, such as, but not limited to, the temperature, humidity, air quality, or combinations thereof of a transport unit. Examples of transport units include, but are not limited to, trucks, containers (such as containers on flatbed trucks, intermodal containers, ocean containers, rail containers, etc.), box trucks, semi-tractor-trailers, buses, or other similar transport units. Summary of the Invention

[0003] The embodiments described herein relate to energy management for systems used in transportation. More specifically, the embodiments described herein relate to a generator for providing energy or charging devices and systems associated with transportation components.

[0004] The embodiments described herein relate to a generator that simultaneously supplies different voltages to multiple components, some of which cannot receive the full supply voltage from the generator without adding a transformer to the device or system.

[0005] In some embodiments, a transport climate control system may include an energy storage management system designed for a range of voltages and frequencies. However, certain product requirements may require a supply voltage exceeding the voltage range of a specified energy storage management system. The embodiments described herein may provide a generator that supplies voltage exceeding the voltage range of a specified energy storage management system to certain components (e.g., compressors, one or more condenser fans, one or more evaporator blowers, etc.), while still allowing the same generator to supply voltage within the specified voltage range of the energy storage management system.

[0006] According to at least one exemplary embodiment, a three-phase generator includes: a stator winding having a plurality of coil turns, wherein the stator winding is connected to an electrical load; a distal output power lead disposed at a distal end of the stator winding; and at least one intermediate output power lead disposed at an intermediate distance between an energy source and the distal end of the stator winding, wherein the number of coil turns determines the generator output voltage at the distal output power lead and at the at least one intermediate output power lead.

[0007] According to at least one other exemplary embodiment, a transportation climate control system includes: a generator that provides three-phase AC voltage; a climate control circuit that includes a compressor powered by a prime mover; a first load that is powered in a first mode; and a second load that is powered in a second mode. Attached Figure Description

[0008] Refer to the accompanying drawings, which form part of this disclosure and illustrate embodiments described herein. Various changes and modifications will become apparent to those skilled in the art from the following detailed description. The same reference numerals are used in different figures to indicate similar or identical items.

[0010] Figure 2 A schematic block diagram of a three-phase generator for providing power to transport climate control system elements and components, according to at least one embodiment described herein, is shown.

[0012] The embodiments described herein relate to energy management for systems used in transportation. More specifically, the embodiments described herein relate to a generator for providing energy or charging devices and systems associated with transportation components.

[0013] The embodiments described herein relate to a generator that can simultaneously supply different voltages to multiple components, some of which cannot receive the full supply voltage from the generator without adding a transformer to the device or system.

[0014] In particular, under varying AC and DC load conditions, demand can be adapted by a common generator without activating a transformer.

[0015] In some embodiments, a transport climate control system may include an energy storage management system designed for a range of voltages and frequencies. However, certain product requirements may require a supply voltage exceeding the voltage range of a specified energy storage management system. The embodiments described herein may provide a generator that supplies voltage exceeding the voltage range of a specified energy storage management system to certain components (e.g., compressors, one or more condenser fans, one or more evaporator blowers, etc.), while still allowing the same generator to supply voltage within the specified voltage range of the energy storage management system.

[0016] The embodiments described herein can accommodate load demands smaller than those output from a single source without requiring additional power factor correction circuitry. For example, inductive loads (e.g., transformers, induction motors, etc.) may have hysteresis currents that require reactive power for magnetization. For lightly loaded machines, the required reactive current may be too high, and the increased current used for reactive power can cause energy losses in the energy management system because the current and voltage are out of phase and the current may not be sinusoidal.

[0017] Therefore, the embodiments described and enumerated herein improve the energy efficiency of energy management systems in transportation. In some embodiments, this can save fuel for the energy management system by using existing generators, thereby eliminating the need for additional components (e.g., electronic energy converters or transformers), assisting the energy management system in meeting energy quality regulations, promoting improved reliability, and reducing costs.

[0018] In the following detailed description, reference is made to the accompanying drawings, which are included as a part of the specification. In the drawings, like symbols generally identify like parts unless the context otherwise requires. Furthermore, unless otherwise indicated, the description of each successive drawing may refer to features from one or more of the preceding drawings to provide a clearer background and more substantial description of the present exemplary embodiments. Likewise, the exemplary embodiments described in the detailed description, drawings, and claims are not intended to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter set forth herein. It will be understood that various aspects of this disclosure as generally described herein and shown in the accompanying drawings can be arranged, replaced, combined, separated, and designed in a wide variety of different configurations, all of which are expressly contemplated herein.

[0019] Although the embodiments described below illustrate different implementations of a transport climate control system, it will be understood that electrically powered accessories are not limited to a transport climate control system or a climate control unit (CCU) of a transport climate control system. A CCU may be, for example, a transport refrigeration unit (TRU). In other embodiments, electrically powered accessories may be, for example, cranes attached to vehicles, cement mixers attached to trucks, one or more food appliances on food trucks, booms attached to vehicles, concrete pump trucks, garbage trucks, fire trucks (with powered ladders, pumps, lights, etc.), etc. Electrically powered accessories may require continuous operation even when the vehicle's ignition is off and / or the vehicle is parked, idling, and / or charging. Electrically powered accessories may also require significant power to operate independently of the vehicle's operating mode, as needed, continuously, and / or autonomously (e.g., controlling the temperature / humidity / airflow of the climate-controlled space).

[0020] Figure 1 An embodiment of a transport climate control system 100 for a transport unit (TU) 125 attached to a tractor unit 120 is shown. The transport climate control system 100 includes a control unit (CCU) 110 that provides environmental control (e.g., temperature, humidity, air quality, etc.) within the interior space 150 of the TU 125. The transport climate control system 100 also includes a transport climate control system controller 170 and one or more sensors (not shown) configured to measure one or more parameters of the transport climate control system 100 and to transmit parameter data to the transport climate control system controller 170.

[0021] CCU 110 is disposed on the front wall 130 of TU 125. In other embodiments, it will be understood that CCU 110 may be disposed, for example, on the roof 126 of TU 125 or on another wall. A tractor unit 120 is attached to transport unit 125 and configured to tow the transport unit. It will be understood that the embodiments described herein are not limited to truck and trailer units, but are applicable to any other type of transport unit (e.g., containers on flatbeds, intermodal containers, etc.), trucks, box trucks, or other similar transport units.

[0022] The programmable transport climate control system controller 170 may include a single integrated control unit 160, or a distributed network that may include transport climate control system control elements 160, 165. The number of distributed control elements in a given network may depend on the specific application of the principles described herein. The transport climate control system controller 170 is configured to control the operation of the transport climate control system 100. The transport climate control system controller 170 may also regulate the operation of the transport climate control system 100 to prevent overload of the energy source (e.g., a diesel engine) during changes in the operating mode of the transport climate control system, as described in more detail below.

[0023] The transport climate control system 100 can be powered by one or more energy sources (not shown), including, for example, prime movers (e.g., diesel engines), generator sets, shore power, fuel cells, solar panels, etc. In at least one other embodiment, one or more energy sources (e.g., prime movers, fuel cells, etc.) may be located within the CCU 110. In at least one other embodiment, one or more energy sources may be separate from the CCU 110 and located within the tractor unit 125 (e.g., prime movers for moving the tractor unit 120, etc.) or the CCU 110. In other embodiments, one or more energy sources may be located on, attached to, or located within the TU 120 (e.g., generator sets, solar panels, etc.). Moreover, in some embodiments, one or more energy sources may be external to the CCU 110, TU 120, and tractor unit 125 (e.g., shore power, etc.).

[0024] When the energy source includes a diesel engine, the diesel engine can be less than 25 horsepower. Furthermore, the diesel engine can be a two-speed engine, a variable-speed engine, etc. In some cases, it may be necessary for the energy source not to exceed a predetermined power level. Not exceeding the predetermined power level can, for example, prevent the energy source from being overloaded, or prevent the energy source from exceeding, for example, government or customer requirements (e.g., noise level regulations, emission regulations, fuel usage restrictions, etc.).

[0025] Figure 2 A schematic block diagram of one embodiment of an energy management system 200 for providing energy to, for example, a transport climate control system 100 is shown. System 200 includes: an AC power distribution network 205; an energy converter 210; multiple variable AC loads 215a, 215b; multiple variable DC loads 220a, 220b; a transport climate control system controller 230; an energy converter input sensor 260; and an energy converter output sensor 265. Figure 2The number of features shown and described herein, including but not limited to AC loads 215a and 215b and DC loads 220a and 220b, is not limited thereto. That is, Figure 2 The embodiments shown and described herein are non-limiting examples.

[0026] According to at least one embodiment, the AC power distribution network 205 can be configured to receive three-phase AC power from an electric motor 235 energized by the AC power distribution network 205 and powered by a prime mover 240 (e.g., when the transport climate control system is in transit), a generator 242 powered by a prime mover 240 (e.g., when the transport climate control system is in transit), and / or from a shore / utility energy source 245 (e.g., when the transport climate control system is not in transit).

[0027] The prime mover 240 may be, for example, a diesel engine, a compressed natural gas engine, etc. In some embodiments, the prime mover 240 may power the energy management system 200 and other loads. For example, in at least one embodiment, the prime mover 240 may be used to operate a vehicle, and the energy management system 200 may obtain a variable amount of energy from the prime mover 240 based solely on the power required to operate the vehicle. In at least one other embodiment, the prime mover 240 may be located in the CCU 110 of the transportation climate control system. In some embodiments, the prime mover 240 may be located in a tractor / truck providing transportation for the transportation climate control system.

[0028] The electrical machine 235 may be and / or include, for example, an induction motor (e.g., an asynchronous induction motor), a motor, etc.

[0029] Generator 242 is configured to provide energy to AC distribution network 205. In some embodiments, generator 242 may be a CCU (e.g., Figure 1 The generator 242 is a part of and / or disposed therein (CCU 110 shown). In other embodiments, the generator 242 may be part of a separate and different generator set from the CCU. In these embodiments, the generator set may, for example, be attached to / disposed on a transport unit (e.g., TU 120).

[0030] An embodiment of generator 242 may be a split-phase power system that promotes high conduction efficiency and low safety risk by dividing the resulting voltage into smaller portions to provide energy to multiple loads with those smaller voltages, all while drawing current from, for example, prime mover 240 at levels that are typical of full-voltage systems.

[0031] According to the various embodiments described and listed herein, generator 242 may include a three-phase generator that can generate three alternating currents to ensure continuous power production and allow for balanced power modes, thus providing increased utility in commercial and industrial applications.

[0032] The three-phase generator 242 may have multiple stator windings connected thereto, each stator winding having multiple coil turns (see...). Figure 3 According to the various embodiments described and listed herein, the stator windings can be configured in a Y-shape (see [link to documentation]). Figure 3 In this configuration, each stator winding may have at least three output lines that are simultaneously powered to provide a proportion of the generator's total output voltage. These output lines are alternatively referred to as wires or conductors connected to and drawn from the generator's energy source. All voltage outputs can be protected by existing stator overload protectors (not shown), and the full generator output current can be used for the windings.

[0033] In other words, each stator winding may include: a distal output power lead or tap located at the distal end of the stator winding to provide the full output voltage of the generator to the load connected thereto; and at least one intermediate output power lead located at an intermediate distance between the energy source and the distal end of the stator winding to provide a proportion of the full output voltage of the generator 242, such as 25%, 50%, and / or 75%. The number of coil turns or windings from the energy source of the generator 242 to the corresponding output power lead determines the proportion of the full output voltage of the generator provided to the load connected to the corresponding lead.

[0034] According to at least some of the embodiments described and enumerated herein, one or more loads connected to the intermediate output power lead may include an energy storage management system and / or a compressor. However, the embodiments are not limited thereto. Loads that may be connected to the intermediate output power lead may include fan motors, heaters, controllers, etc., in any combination or arrangement.

[0035] Therefore, one or more embodiments described and enumerated herein relate to: a generator 242 that provides three-phase AC voltage; a climate control circuit that includes a compressor 217 that can be electrically powered by the three-phase generator 242; a first load powered in a first mode; and a second load powered in a second mode.

[0036] One or more embodiments may relate to a transport climate control system, wherein a first mode is a first voltage level supplied by a first tap on a corresponding wire of a plurality of wires, and a second mode is a second voltage level supplied by a second tap on a corresponding wire of the plurality of wires, thereby supplying any one of, for example, 25%, 50%, and / or 75% of the total output voltage of generator 242 to the load connected to the corresponding tap.

[0037] In at least one embodiment of the transport climate control system 100, one or more of the electric motor 235, generator 242, prime mover 240 and compressor 217 may be part of the energy management system 200.

[0038] AC distribution network 205 can be configured to direct three-phase AC power to energy converter 210, compressor 217, and multiple variable AC loads 215a and 215b.

[0039] Generator 242 can supply three-phase AC power to energy converter 210, compressor 217, and other AC loads 215a, 215b, including but not limited to condenser fan motors, evaporator blowers, drain pipe heaters, heater connection devices, controllers, and energy storage management system 247. At least one embodiment of the transport climate control system 100 may include energy storage management system 247, which is powered by generator 242 in either a first or second mode. The energy drawn by each of the plurality of AC loads 215a and 215b may vary over time depending on the needs and operation of transport climate control system 100.

[0040] The energy storage management system 247 can receive alternating current (AC) from the generator 242 and can supply electrical energy to the energy converter 210, the transport climate control system controller 230, and various other components of the transport climate control system that require direct current (DC) through the rechargeable energy storage source (RESS) 248. The energy storage management system 247 is configured to monitor the charge level of one or more batteries of the RSS 248 and to charge one or more batteries of the RSS 248. The energy storage management system 247 can communicate with, for example, the transport climate control system controller 230 to provide information on the charge level of one or more batteries of the RSS 248. Furthermore, the energy storage management system 247 can receive instructions from, for example, the transport climate control system controller 230, indicating how much energy from the RSS 248 should be supplied to components of the transport climate control system. In some embodiments, the energy storage management system 247 can be a battery charger. Similarly, in some embodiments, the energy storage management system 247 can have a specified voltage range between 180 volts AC and 506 volts AC.

[0041] In some embodiments, RESS 248 may include one or more batteries. For example, in one embodiment, RESS 248 may include two batteries (not shown). Each of these batteries may also be connected to energy converter 210 via energy storage management system 247. It will be understood that RESS 248 can provide sufficient energy to power transport climate control loads on its own. In some embodiments, RESS 248 can provide 12 volts DC or 24 volts DC. In other embodiments, RESS 248 can provide 48 volts DC.

[0042] In some embodiments, generator 242 can supply voltages beyond the specified voltage range of energy storage management system 247 to components (e.g., compressor 217, one or more condenser fans, one or more evaporator blowers, etc.), while still allowing the same generator to supply voltages within the specified voltage range of the specified energy storage management system to energy storage management system 247.

[0043] As a non-limiting example, when operating at any operating frequency, generator 242 can supply 537 volts AC (ranging from 483 volts AC to 590 volts AC). When the specified voltage range of energy storage system 247 is between 180 volts AC and 506 volts AC, there is a possibility that generator 242 may supply a voltage exceeding 506 volts AC. As stated above and regarding Figure 3In more detail, the energy storage management system 247 can be connected to the intermediate output power lead of the generator 242 such that the maximum voltage received by the energy storage management system 247 is within a specified voltage range of the energy storage management system (e.g., between 180 volts AC and 506 volts AC). In this example, when the energy storage management system 247 is connected to the intermediate output power lead of the generator 242, which supplies 75% of the total output voltage of the generator 242, the energy storage management system 247 can receive electrical energy between 362 volts AC and 443 volts AC.

[0044] The transport climate control system controller 230 is an electronic device configured to manage, command, guide, and regulate the behavior of one or more climate control components of the transport climate control system, including climate control circuitry (e.g., evaporator, condenser, compressor 217, expansion valve (EXV), electronic throttle valve (ETV), etc.), multiple varying AC loads 215a and 215b, multiple varying DC loads 220a and 220b, and electric motor 235. Although not shown, the transport climate control system controller 230 is also configured to communicate with an energy converter controller 210 that provides energy management for the transport climate control system.

[0045] Compressor 217 may be a refrigerant compressor that compresses a refrigerant for use in, for example, a climate control loop. According to one or more embodiments described and enumerated herein, compressor 217 may be electrically driven, receiving electric power from either a three-phase generator 242 or an AC power distribution network 205. Alternatively, compressor 217 may be mechanically driven, receiving mechanical power from a prime mover 240 and / or an electric motor 235.

[0046] According to at least one embodiment described and enumerated herein, energy converter 210 can receive three-phase alternating current (AC) from generator 242. Alternatively or additionally, energy converter 210 can receive three-phase AC from prime mover 240 and / or shore / utility energy source 245. Energy converter 210 is configured to convert the received three-phase AC into direct current (DC) and supply DC to a varying DC load 220 via transport climate control system controller 230. Although Figure 2The illustrated embodiment shows an energy converter 210 supplying DC power to a plurality of varying DC loads 220 via a transport climate control system controller 230. However, it will be understood that in other embodiments, the energy converter 210 may supply DC power to one or more of the plurality of varying DC loads 220 without going through the transport climate control system controller 230. In some embodiments, the energy converter 210 may also supply DC power to an optional DC power storage device 255. The energy converter 210 is controlled by an energy converter controller 212.

[0047] It will be understood that the three-phase AC power received by the energy converter 210 is a changing three-phase AC power signal that can vary over time based on, for example, the changing load demand from multiple changing AC loads 215a and 215b, the changing three-phase AC power supplied by the electric motor (e.g., the power generated by the prime mover 240 is changed due to the change in load demand from the compressor 217, etc.).

[0048] The energy converter 210 is also configured to use reactive three-phase AC power to supplement the variable AC loads 215a and 215b with the three-phase AC current supplied by the electric motor 235, shore / utility energy source 245 and / or generator 242, in order to help reduce energy efficiency losses.

[0049] Figure 3 An electric stator 300 according to at least one embodiment described herein is shown.

[0050] According to at least one embodiment of the stator 300 corresponding to the three-phase generator 242, the stator windings 302 can be configured in a Y-shape. Each stator winding 302A, 302B, and 302C can have at least three output lines that are simultaneously supplied with energy to provide a proportion of the generator's total output voltage; these output lines are alternatively referred to as wires or conductors connected to and drawn from the generator's energy source. All voltage outputs can be protected by existing stator overload protectors (not shown), and the full generator output current can be used for the windings. Furthermore, energy flow overload protectors can be provided to cover the convergence point of multiple distributing wires, for example, at the convergence point of the Y-shape configuration.

[0051] exist Figure 3 In one embodiment, each stator winding 302A, 302B, and 302C may include a remote output power lead or tap 305A, 305B, and 305C located at the far end of the respective stator winding 302A, 302B, and 302C to provide the full output voltage of the generator 242 to the load connected thereto.

[0052] In addition, each stator winding 302A, 302B and 302C may include a remote output power lead or tap, and may include at least one intermediate output power lead disposed at an intermediate distance between the energy source and the remote ends of the stator windings 302A, 302B and 302C to provide a proportion of the total output voltage of the generator 242.

[0053] Therefore, in Figure 3 In one embodiment, intermediate output leads or taps 310A, 310B, and 310C on the corresponding stator windings 302A, 302B, and 302C provide 75% of the total output voltage of the generator 242 to the load connected thereto; intermediate output leads or taps 315A, 315B, and 315C on the corresponding stator windings 302A, 302B, and 302C provide 50% of the total output voltage of the generator 242 to the load connected thereto; and intermediate output leads or taps 320A, 320B, and 320C on the corresponding stator windings 302A, 302B, and 302C provide 25% of the total output voltage of the generator 242 to the load connected thereto.

[0054] The number of coil turns or windings from the energy source of generator 242 to the corresponding output power lead depends on the proportion of the generator's total output voltage to the load connected to the corresponding lead.

[0055] Therefore, generator 242 can simultaneously supply different voltages to multiple components, some of which cannot receive the full supply voltage from generator 242 (e.g., energy storage management system 247) without adding an electronic energy converter or transformer to the device or system.

[0056] Based on the foregoing, it will be understood that various embodiments of this disclosure have been described herein for illustrative purposes, and various modifications may be made without departing from the scope and spirit of this disclosure. Therefore, the various embodiments disclosed herein are not intended to be limiting, and the true scope and spirit are indicated by the appended claims.
