Embodiment 1

[0046] This embodiment provides a control system for a pure electric vehicle power battery, such as figure 1 As shown, the system includes a motor cooling circuit, a battery cooling circuit, a warm air circuit, an air conditioning refrigeration circuit and a passenger compartment 106 .

[0047] The motor cooling circuit is provided with a power motor body 104 and a radiator three 403, the battery cooling circuit is provided with a power battery 105, a radiator three 403 and a radiator two 402, and the warm air circuit is provided with a radiator three 403, a radiator four 404 and a fan Two 502, the air-conditioning refrigeration circuit is provided with radiator two 402, radiator five 405 and air-conditioning compressor assembly 602, radiator five 405 is connected with fan two 502, and passenger compartment 106 is regulated by fan two 502.

[0048]Radiator 3 403 can exchange heat between the coolant in the motor cooling circuit and the coolant in the warm air circuit and batte...

Embodiment 2

[0066] This embodiment provides a control method for a power battery of a pure electric vehicle, using the control system for a power battery of a pure electric vehicle provided in Embodiment 1.

[0067] When the whole vehicle is in charging and heating mode and the temperature of the power battery 105 is lower than the first temperature (in this embodiment, the first temperature is set to 0°C), the power motor body 104 converts electric energy into heat energy, and then passes through the motor cooling circuit and the battery The cooling circuit heats the traction battery 105 .

[0068] The specific control steps are: open port a and port b of three-way valve one 305, open port a and port b of three-way valve two 303, open port a and port b of three-way valve three 304, Turn on water pump one 201 and water pump two 202, turn off air conditioner 602, turn off fan one 501, through the vector control of power motor body 104, control power motor body 104 to work in the locked-rot...

Abstract

The invention belongs to the technical field of pure electric vehicles, and discloses a control system and method for a power battery of a pure electric vehicle. The system comprises: a motor cooling loop which is provided with a power motor body and a radiator III; a battery cooling loop is provided with a power battery, a radiator III and a radiator II; a warm air loop is provided with a radiator III, a radiator IV and a fan II; an air conditioner refrigerating circuit is provided with a radiator II, a radiator V and an air conditioner compressor assembly, and the radiator V is connected with the fan II; and a passenger compartment, wherein the temperature is adjusted through the fan II. Compared with an existing power battery control system, one high-voltage electrical component electric heating device is omitted, the power battery and the passenger compartment are heated, and the system cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, in particular to a control system and method for a power battery of a pure electric vehicle. Background technique [0002] Short driving range is the most important factor restricting the development of pure electric vehicles. To increase the driving range of pure electric vehicles, increasing the power battery is the most important way. On the basis of ensuring the function and performance of pure electric vehicles, reducing the cost of electric vehicles is an important way to promote pure electric vehicles. [0003] The hardware cost of pure electric vehicles is basically not affected by sales volume, but the software cost can be greatly reduced as sales volume increases. Therefore, it is an important way to reduce the cost of pure electric vehicles to develop functions that replace certain hardware through software development, that is, control methods. [0004] The power syst...
