Description

Technical Field

[0001] The utility model relates to the technical field of hybrid power supply, and particularly relates to a temperature-controllable electric-electric hybrid power supply component. Background Technique

[0002] With the increasingly serious energy and environmental problems, the promotion of green energy has been continuously strengthened globally. Especially, the new energy industry has been particularly prominent in the applications in multiple fields, including automotive power, industrial and commercial wind and photovoltaic energy storage, port facilities, and civil electricity, etc.

[0003] In recent years, with the popularization of new energy technologies, higher requirements have been put forward for their safety, lifespan, and cost, etc. As is well known, batteries store electrical energy through chemical reactions. However, if the output conditions of the batteries are not properly controlled, it will seriously affect their performance and may even pose potential safety hazards. Therefore, how to optimize the output conditions of batteries has become the focus of research. One solution is to use high-power energy storage devices in combination with batteries to make up for the deficiencies of batteries in high-power output. However, existing coaxial parallel dual systems often face the problem of uneven output distribution and are difficult to achieve energy recovery (such as Figure 1 ). In addition, parallel power sources usually require the consistency of the output voltage and current of each DC power supply, which undoubtedly increases the regulation difficulty and complexity of the system. More importantly, under long-term high-power output conditions, this mode may bring some potential problems.

[0004] Firstly, long-term high-power output will cause a large amount of heat to be generated inside the system. Overheating will not only reduce the operating efficiency of the equipment but may also cause irreversible damage to the components inside the equipment. Secondly, the high-temperature environment will accelerate the aging process of the components, resulting in a shortened service life of the equipment and an increase in the costs of maintenance and replacement. Finally, and most importantly, the increase in safety risks cannot be ignored. High temperature may not only damage the equipment but also trigger more serious safety accidents. Therefore, in the design and use of the dual-power-source parallel output mode, perfect heat dissipation measures and safety mechanisms must be available to ensure that the equipment can operate safely and reliably under various working conditions. Content of the Utility Model

Through such optimization, not only the efficiency of the system is improved, but also its overall stability is enhanced. This is particularly important for application scenarios that require long-term stable operation, as it reduces the risk of failures caused by voltage or current fluctuations and extends the service life of the equipment. In short, this design provides a more efficient and reliable solution in power transmission and conversion. BRIEF DESCRIPTION OF THE DRAWINGS

[0096] Embodiment 1: A temperature-controllable electric-electro-hybrid power supply module for a load vehicle

[0097] When the temperature-controllable electric-electro-hybrid power supply module is used for a vehicle, the high-voltage battery pack is selected from a lithium iron phosphate battery pack, the high-voltage high-power device group is selected from a supercapacitor, the BMS system is a vehicle power control system, the load object is a vehicle, the motor component is a generator, and the rest of the structure is the same as above;

[0098] A working method of a temperature-controllable electric-electro-hybrid power supply module for a load vehicle is as follows:

[0099] 1. Normal driving activities

[0100] When the vehicle is in normal driving or other situations where high power output is not required, the lithium iron phosphate battery pack is controlled by the first controller to perform constant voltage charging on the supercapacitor energy device pack through the DC-DC controller, and the supercapacitor energy device pack supplies power to the load vehicle through the second controller.

[0101] 2. High-power drive control

[0102] When it is determined that the vehicle is in a situation where high power output is required, such as going uphill, accelerating rapidly, or on a muddy road, the vehicle power control system sends signals to the first controller and the second controller. The first controller controls the lithium iron phosphate battery to output at the maximum power to the supercapacitor energy device pack, and the second controller adjusts the output of the supercapacitor device pack according to the signals of the vehicle power control system. Among them, the maximum output limit is the constant output of the lithium iron phosphate battery pack (the control output condition of the first controller) + the output of the supercapacitor energy device pack to meet the instantaneous high-power demand;

[0103] 3. Charging mode

[0104] (1) Charging during operation:

[0105] When the state of charge of the supercapacitor is relatively low due to high-power output and the vehicle is still in a driving state, the first controller will make the lithium iron phosphate battery pack output at the maximum, and regard the supercapacitor as a conductor and directly act on the vehicle; after meeting the basic driving requirements of the vehicle, the excess energy output by the first controller is used to charge the supercapacitor pack through the DC-DC controller to prepare for meeting the next high-power demand.

[0106] (2) Charging of the supercapacitor:

[0107] When the vehicle is running smoothly or in a stopped state, the voltage detector inside the supercapacitor energy device pack detects the state of charge, and the first controller controls the lithium iron phosphate battery pack to charge the supercapacitor.

[0108] (3) External charging:

[0109] After the vehicle power control system receives the charging signal, it sends signals to the first controller and the second controller. The first controller first cuts off the output of the lithium iron phosphate battery pack to the DC-DC controller, and then controls the external power supply to directly charge the lithium iron phosphate battery pack and limits the charging power according to the battery state information of the lithium iron phosphate battery pack to protect the lithium iron phosphate battery pack; the second controller cuts off the energy supply to the vehicle.

[0110] (4) Energy recovery:

[0111] When the vehicle is in a downhill, decelerating, or hard - decelerating situation, the generator transfers the recovered energy to the second controller, and the second controller with two - way control recovers the energy into the supercapacitor energy device group.

[0112] 4. Special environment driving mode

[0113] When the temperature sensors located in the lithium iron phosphate battery pack or / and the supercapacitor device group detect that the temperature is higher than the vehicle - defined temperature range, they send a message to the vehicle power control system. The vehicle power control system that receives the message sends a cooling signal to the second controller. The second controller supplies power to the temperature control unit and transmits the cooling signal. After receiving the cooling signal, the temperature control unit starts the water pump of the circulation pipeline 21 where the temperature sensor that sent the signal is located, so that the condensate flows into the circulation pipeline 21 and flows through the inside of the lithium iron phosphate battery pack or / and the supercapacitor device group, realizing temperature control of the entire device group and ensuring the reliability of the output environment.

[0114] When the temperature sensor detects that the temperature of the lithium iron phosphate battery pack or / and the supercapacitor device group is lower than the minimum vehicle - defined temperature, it sends a signal to the vehicle power control system. The vehicle power control system sends signals to the supercapacitor device group and the second controller respectively. After receiving the signal, the supercapacitor device group starts pre - braking heating. At the same time, the second controller supplies power to the temperature control unit and sends a signal. The temperature control unit turns on the water pump of the circulation channel 21 where the lithium iron phosphate battery pack is located, so that the heated condensate flows through the inside of the lithium iron phosphate battery pack; when the temperatures of both reach the specified temperature, the temperature sensor transmits the signal to the control management center through communication connection, and then the control management center conveys the signal to the DC - DC controller, and the high - voltage battery pack can perform energy output. At this time, the output supplies energy to the supercapacitor bank and the vehicle for driving.

[0115] Embodiment 2 A temperature - controllable electric - electric hybrid power supply module for industrial and commercial energy storage

[0116] This embodiment is a temperature - controllable electric - electric hybrid energy storage module for industrial and commercial energy storage, and its main features are:

[0117] The lithium iron phosphate battery pack is used as the energy source of the high - voltage battery pack, the lithium titanate battery device group is used as the energy source of the high - voltage and high - power device group, the BMS system is the power control system, the load object is industrial and commercial energy storage, and the principles of the remaining component mechanisms are the same as the above description.

[0118] The working mode of the temperature - controllable electric - electric hybrid energy storage module for industrial and commercial energy storage is as follows:

[0119] 1. Normal power consumption mode

[0120] When the power demand does not exceed the output limit of the lithium iron phosphate battery group controlled by the first controller, the first controller controls the lithium iron phosphate battery group to charge the lithium titanate battery device through the DC-DC controller, and then the lithium titanate battery device group supplies external power through the second controller.

[0121] 2. Peak period, high power demand mode

[0122] When the power demand exceeds the output limit of the lithium iron phosphate battery group controlled by the first controller, the power control system sends a signal to the first controller and the second controller. The first controller controls the lithium iron phosphate battery to output to the lithium titanate battery device group at maximum power. The second controller adjusts the output of the lithium titanate battery device group according to the signal of the power control system to meet the power demand.

[0123] 3. System power replenishment

[0124] Industrial and commercial energy storage is mostly used for the peak-valley price difference of electricity. When the electricity price is at a low point, the power control system sends a signal to the first controller after receiving the charging signal. The first controller first cuts off the output of the lithium iron phosphate battery pack to the DC-DC controller, and then controls the external power supply to directly charge the lithium iron phosphate battery pack. It also detects the voltage of the lithium iron phosphate battery pack through the voltage detector at any time, and limits the charging power according to the battery status information. The second controller cuts off the supply of external electricity.

[0125] 4. System operation in high temperature environment

[0126] When the temperature sensor located in the lithium iron phosphate battery pack and / or the lithium titanate battery device group detects that the temperature is higher than the temperature range set by the power system, a high temperature alarm is issued to the power control system. The power control system that receives the signal sends a cooling signal to the second controller. The second controller supplies power to the temperature control unit and sends a cooling signal. After receiving the cooling signal, the temperature control unit turns on the water pump of the circulation pipeline 21 where the temperature sensor that issues the temperature alarm is located, so that the condensate enters the circulation pipeline 21 and flows through the lithium iron phosphate battery pack and / or the supercapacitor device group, thereby cooling the entire device group.

[0127] 5. System operation in low temperature environment

[0128] When the temperature sensor detects that the temperature of the lithium iron phosphate battery pack or / and the lithium titanate battery device group is lower than the minimum temperature defined by the power system, it sends a low-temperature alarm to the power control system. The power control system sends signals to the lithium titanate battery device group and the second controller respectively. The received lithium titanate battery device group starts pre-braking heating. At the same time, the second controller supplies power to the temperature control unit and sends a signal. The temperature control unit turns on the water pump of the circulation pipeline 21 where the lithium titanate battery device group is located, so that the heated condensate flows into the circulation pipeline 21 inside the lithium iron phosphate battery pack; when the temperatures of both rise to the specified temperature, the temperature sensor transmits the signal to the control and management center through communication connection, and then the control and management center conveys the signal to the DC-DC controller, and the controllable temperature electric-electric hybrid energy storage module starts to work normally.

[0129] The special environment includes a high-temperature environment where heat is generated during long-term operation, or an environment with a relatively high or low temperature during its own use. In this environment, the efficiency of energy devices will be seriously affected. At this time, the temperature control component needs to work continuously to ensure that the lithium iron phosphate battery pack and the lithium titanate battery pack are in a suitable working environment, thereby improving the user experience and increasing the service life of the product, etc.

Those of ordinary skill in the art can make changes, modifications, substitutions, and deformations to the above embodiments within the scope of the present invention.
