Abstract

The invention relates to a battery heating device with a heat management function. The battery heating device comprises a box, a voltage and temperature acquisition device, a battery heater and a battery management system. The battery heater comprises a first pressure plate, a second pressure plate and a battery connection device. The first pressure plate and the second pressure plate are arranged on two sides of the battery connection device respectively, and heating wires for heating batteries on the battery connection device is penetratingly arranged between the first pressure plate and the second pressure plate. The voltage and temperature acquisition device is arranged on one side of the battery heater, acquires temperatures of the batteries through a temperature sensor connected with the voltage and temperature acquisition device and acquires voltages of the batteries through wires arranged on electrodes of the batteries. By the battery heating device with the heat management function, problems of nonuniformity in heating, long heating time, lack of reasonability in heating control, unreliability in sampling, harness unattractiveness, complexity in assembly and failure in vibration resistance of battery packs and the like of existing heating devices are solved.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a battery heating device with heat management. Background technique [0002] Power batteries are the core components of electric vehicles, and the reliability of batteries directly affects the performance of the vehicle. When used in severe cold areas, the discharge performance and charge acceptance of power batteries are greatly reduced by the low temperature environment, thus affecting the power performance and driving range of electric vehicles in severe cold areas. [0003] Due to the special environmental requirements of the power battery, the best performance of the battery cannot be exerted or even work normally when the temperature is too high or too low. In order to solve the performance problems of electric vehicle batteries caused by the above-mentioned low temperature environment, it is very necessary to use a heating device for the battery pack when the temperature is low i...
