Problems solved by technology

[0004] Therefore, in order to make the viscosity of the electrolyte inside the battery meet the electricity demand of the vehicle, it is necessary to preheat the battery. However, the existing heating system generally uses electric heating, which consumes power and is unsafe. Therefore, we propose waste heat battery heating system

Abstract

The invention relates to the technical field of automobile battery heating, and discloses a waste heat battery heating system which comprises an engine cooler, a thermostat, a one-way valve, a water pump, a battery heater and a generator radiator. A cooling water outlet of the engine cooler is connected with the water pump through a pipeline, and a thermostat and a one-way valve are installed on the pipeline between the engine cooler and the water pump. According to the waste heat battery heating system, heat generated by the generator is used for heating water, warm water is guided into the battery heater, the temperature of the heater is increased through the warm water, so that a storage battery is preheated, the warm water is subjected to heat dissipation through the generator radiator after being used, and the warm water is guided into the generator cooler again, so that cyclic utilization is achieved; and the viscosity of the electrolyte can meet the electricity demand of the vehicle while energy is saved.

Description

technical field [0001] The invention relates to the technical field of automobile battery heating, in particular to a waste heat battery heating system. Background technique [0002] For new energy vehicles, in order to improve the battery life of the vehicle in winter, the battery needs to be preheated to meet the needs of the car in winter, and the heating technology of the battery will vary depending on the vehicle. [0003] First of all, the electrolyte plays the role of conducting ions between the positive and negative electrodes of the lithium battery, which is the guarantee for the lithium ion battery to obtain the advantages of high voltage and high specific energy. Therefore, the low viscosity of the electrolyte can start the movement of lithium ions. If the viscosity is high, it will form a certain internal resistance, thereby preventing the movement of lithium ions, and the battery preheating is under the condition of low temperature, the viscosity of the electrol...
