Problems solved by technology

[0002] With the rise of new energy electric vehicles, for the core components of new energy electric vehicles, the development of power batteries and the improvement of use efficiency are the focus of related industries. The development of power batteries is particularly rapid, but in the process of development, The cooling and heating of the power battery is particularly prominent, because it involves the efficiency of its charge and discharge. At present, the best working temperature of the lithium battery power battery is 20 ~ 45 ℃, so the lithium battery must be tested in different environments. Different treatment, the power battery needs

Embodiment 1

[0020] As in the accompanying drawings Figure 1 to Figure 5 A lithium battery energy storage high-efficiency thermal management unit is shown, including a box body 1, a shell-and-tube condenser 2, a compressor 3, a plate heat exchanger 4, a water pump 5, a low-temperature radiator 6, and an antifreeze pipeline 7. A liquid inlet pipe 8 and a liquid outlet pipe 9 are installed on one side of the body 1, and the shell-and-tube condenser 1 and the liquid inlet pipe 8 are connected through an antifreeze pipe 7, and a three-way two-position solenoid valve A10 and The three-way two-position solenoid valve B11, the first valve port 12 of the three-way two-position solenoid valve A10, and the third valve port 14 of the three-way two-position solenoid valve B11 are all connected to the shell-and-tube condenser 2 through the antifreeze pipeline 7, The second valve port 13 of the three-way two-position solenoid valve A10 and the fourth valve port 15 of the three-way two-position solenoid...

Embodiment 2

[0026] As in the accompanying drawings Figure 6 A lithium battery energy storage high-efficiency thermal management unit shown in the figure has two working modes, cooling mode and heating mode, and the cooling mode can be divided into three levels according to the cooling intensity, divided into The low gear, middle gear and high gear are implemented by turning on different numbers of cooling fans in the low gear and the middle gear, and the high gear is to turn on the compressor for operation. The cooling operation path of these three gears is the same;

[0027] Here, take the high-end operation mode as an example. First, a part of antifreeze liquid is injected through the liquid injection pipe 18, so that the internal water pump 5 can run, and then the compressor starts to work, and the refrigerant is pressurized by the compressor. After the shell-and-tube condenser 2 is cooled, it changes from a gaseous state to a liquid state, and the liquid refrigerant enters the plate ...

Abstract

The invention discloses a lithium battery energy storage efficient heat management unit. The unit comprises a box body; a three-way two-position electromagnetic valve A and a three-way two-position electromagnetic valve B are installed in the box body; a first valve port of the three-way two-position electromagnetic valve A and a third valve port of the three-way two-position electromagnetic valve B are both connected with a shell-and-tube condenser through an anti-freezing solution pipeline; a second valve port of the three-way two-position electromagnetic valve A and a fourth valve port of the three-way two-position electromagnetic valve B are both connected with a low-temperature radiator through an anti-freezing solution pipeline; the other valve port of the three-way two-position electromagnetic valve A is connected with the input end of a water pump through an anti-freezing solution pipeline; the other valve port of the three-way two-position electromagnetic valve B is connected with the output end of the water pump through an anti-freezing solution pipeline; the other end of the low-temperature radiator is connected with a plate heat exchanger through an anti-freezing solution pipeline. The opening and closing of the corresponding valves ports of the three-way two-position electromagnetic valve A and the three-way two-position electromagnetic valve B and the startup and stop of the water pump are controlled, so that an anti-freezing solution in the management unit can be changed, and therefore, a refrigeration mode and a heating mode can be achieved.

Description

technical field [0001] The invention relates to the technical field of power battery equipment, in particular to a high-efficiency thermal management unit for lithium battery energy storage. Background technique [0002] With the rise of new energy electric vehicles, for the core components of new energy electric vehicles, the development of power batteries and the improvement of use efficiency are the focus of related industries. The development of power batteries is particularly rapid, but in the process of development, The cooling and heating of the power battery is particularly prominent, because it involves the efficiency of its charge and discharge. At present, the best working temperature of the lithium battery power battery is 20 ~ 45 ℃, so the lithium battery must be tested in different environments. Different treatment, the power battery needs to be cooled in the hot summer, it only needs to be properly cooled in spring and autumn, and it needs to be heated in the ...
