Detailed Description
For further details of the battery thermal management system and the control method thereof according to the present invention, the following is a further description with reference to the accompanying drawings, wherein the broken lines represent the electrical connections between the components, and the arrows in the lines indicate the direction of water flow.
As shown in fig. 1, the battery thermal management system of the invention comprises a whole vehicle controller 9, a heater 4, an air conditioner 2, a power battery 8, an engine tail gas heater 11, a battery air inlet channel 1, an air conditioner air inlet channel 3, a water inlet valve 5, a heater water inlet pipe 6, a heater water outlet pipe 7 and a water pump 12; the heater 4 is provided with an adjustable rotating speed fan 14, a radiator 15 and an air inlet 16; the air conditioner 2 is provided with an air conditioner evaporation fan 10, and the air conditioner induced draft channel 3 is provided with an air door 13; the air conditioner 2 is connected with a heater 4 through an air conditioner induced air channel 3, the heater 4 is connected with a power battery 8 through a battery air inlet channel 1, the engine exhaust heater 11 and a radiator 15 of the heater 4 are connected with a heater water inlet pipe 6 and a heater water outlet pipe 7, a water inlet valve 5 is arranged at the end of the heater water inlet pipe 6 close to the radiator 15, and a water pump 12 is arranged at the end of the heater water inlet pipe close to the engine exhaust heater 11; the whole vehicle controller 9 is electrically connected with the adjustable rotating speed fan 14, the air door 13, the water inlet valve 5, the power battery 8, the water pump 12 and the air conditioner evaporation fan 10.
Heating control: when the vehicle is in an environment lower than 10 ℃, the whole vehicle controller 9 monitors the internal temperature of the power battery 8, if the internal temperature of the power battery 8 is lower than 20 ℃, the whole vehicle controller 9 controls the water inlet valve 5 to be opened, then the whole vehicle controller 9 controls the water pump 12 to start working, hot water of the engine exhaust heater 11 enters the radiator 15 of the heater 4 through the heater water inlet pipe 6, air enters the heater through the air inlet hole 16 of the heater 4, the hot water flows through the radiator 15 to heat the air in the heater 4, and then the hot water flows back to the engine exhaust heater 11 through the heater water outlet pipe 7. Meanwhile, the whole vehicle controller 9 controls the adjustable speed fan 14 inside the heater 4 to start and work at the maximum wind speed, and warm air generated in the heater 4 enters the power battery box 8 through the battery air inlet channel 1 to heat the power battery box. When the whole vehicle controller 9 monitors that the internal temperature of the power battery 8 exceeds 40 ℃, the whole vehicle controller 9 firstly controls the water pump 12 to be turned off, after time delay is 5S, the whole vehicle controller 9 controls the water inlet valve 5 to be turned off, and at the moment, hot water of the engine tail gas heater 11 does not enter the heater 4 any more. Meanwhile, the whole vehicle controller 9 controls the adjustable speed fan 14 inside the heater 4 to work at the minimum wind speed, blows off the residual temperature inside the heater 4, and turns off the adjustable speed fan 14 after working for 1 minute. As the temperature of the power battery 8 decreases, the heating operation is repeated again when the temperature decreases to 20 ℃.
And (3) heat dissipation control of an air conditioner: when the vehicle is in an environment with the temperature higher than 30 ℃, the whole vehicle controller 9 monitors the internal temperature of the power battery 8, and if the temperature is higher than 40 ℃, the whole vehicle controller 9 controls the water inlet valve 5 and the water pump 12 to be in a closed state. Subsequently, the whole vehicle controller 9 controls the air conditioner 2 to be started, the air conditioner temperature is set to 25 ℃, the air conditioner evaporation fan 10 is started to work, the air conditioner 2 starts to refrigerate, the whole vehicle controller 9 starts the air conditioner air door 13, and cold air generated by the air conditioner 2 is introduced into the heater 4 through the air conditioner induced air channel 3. Meanwhile, the whole vehicle controller 9 controls the adjustable speed fan 14 inside the heater 4 to work at the maximum wind speed, and the adjustable speed fan 14 enters cold wind into the power battery box 8 through the battery air inlet channel 1 to dissipate heat. When the internal temperature of the power battery 8 is lower than 28 ℃, the whole vehicle controller 9 controls the adjustable speed fan 14 in the heater 4 to stop working, and closes the air conditioner air door 13. As the temperature increases, when the temperature of the power battery 8 increases to 40 ℃, the air conditioner heat radiation operation is repeated again.
Natural wind heat dissipation control: when the vehicle is in an environment of 15-25 ℃, the temperature of the battery system is at a proper temperature, in order to save energy, the whole vehicle controller 9 can control the air conditioner 2 to be not in operation, the water inlet valve 5 and the water pump 12 to be closed, the power battery 8 basically does not need cold air of the air conditioner 2 for heat dissipation, and the environment air is used. Along with the use of the power battery 8, the temperature of the power battery is continuously increased, but because the ambient temperature is lower, the ambient air in the carriage enters the interior of the heater 4 through the air inlet hole 16 of the heater 4, and then is sent into the battery air inlet channel 1 through the speed-adjustable fan 14 in the heater 4, so that the power battery 8 is taken as an air source, and the battery is subjected to heat dissipation. When the internal temperature of the power battery 8 is lower than 20 ℃, the whole vehicle controller 9 controls the heater 4 to adjust the wind speed of the rotating speed fan 14 to be reduced to the minimum or stop the fan, and when the temperature of the power battery 8 is increased to 40 ℃ along with the increase of the temperature, the heat of the power battery is dissipated again.
The working environment temperature of the power battery has a large influence on the service life of the power battery, and long-term experiments and use experience show that if the temperature of the power battery during working is ensured to be within the range of 20-45 ℃, the service life of the power battery can be ensured to reach the design service life. Without a good thermal management system, battery life may be severely reduced or dangerous accidents may occur due to battery abuse.
