Abstract

The invention discloses a cooling management system of a vehicle-mounted electric pile and a vehicle with the cooling management system. The cooling management system of the vehicle-mounted electric pile comprises a vehicle-mounted power supply; the cooling water pump is provided with a cooling liquid outlet and a cooling liquid inlet, a cooling pipeline is connected between the cooling liquid outlet and the cooling liquid inlet, and the cooling pipeline is used for cooling the vehicle-mounted electric pile; the adjusting circuit is connected between the vehicle-mounted power supply and the cooling water pump, the vehicle-mounted power supply supplies power to the cooling water pump through the adjusting circuit, and the adjusting circuit is used for adjusting the voltage of the cooling water pump; and the controller is connected with the adjusting circuit, and the controller is used for controlling connection and disconnection between the vehicle-mounted power supply and the cooling water pump. The model of the cooling water pump can be replaced conveniently, and manufacturing cost and replacement cost are not increased.

Description

technical field [0001] The invention relates to the technical field of vehicle battery cooling, in particular to a cooling management system for a vehicle battery stack and a vehicle having the same. Background technique [0002] In the related technology, the cooling of the on-board electric stack of the vehicle is carried out in the form of cooling liquid delivered by the cooling water pump. The cooling water pump uses the temperature sensor to collect the temperature value near the electric stack, and sends the monitored electric stack temperature to the hydrogen energy vehicle controller through the CAN line. value message. After receiving the message from the cooling water pump, the vehicle controller analyzes and sends out a PWM signal to drive the cooling water pump to reduce the temperature of the stack. Usually, the whole vehicle will first adjust the output voltage and current of the vehicle power supply to the cooling water pump, so that the cooling water pump eq...
