Abstract

The invention provides a vehicle-mounted battery pack heat management system which comprises a battery heat exchange system and an air-conditioner heat exchange system, wherein the battery heat exchange system comprises a circulating pump, a heat exchanger and a battery pack; the battery pack, the circulating pump and the heat exchanger are connected through a circulating pipeline containing a heat exchange liquid inside; a switch valve is arranged between the circulating pump and the heat exchanger; and the air-conditioner heat exchange system comprises a compressor, a radiator A and a radiator B which are connected through a circulating pipeline containing an air conditioner cooling medium inside. The vehicle-mounted battery pack heat management system is formed only by modifying an original air conditioner system, so that the vehicle-mounted battery pack heat management system is simple in structure and convenient to implement; and when the heating capacity of the battery pack is not strong, the vehicle-mounted battery pack heat management system can satisfy the radiation demand of the battery pack only by utilizing the original components in the air conditioner, thereby lowering the energy consumption and protecting the environment.

Description

technical field

[0001] The invention relates to a thermal management system of a vehicle-mounted battery pack. Background technique

[0002] During the high-current charging and discharging process of the power battery, a large amount of heat will accumulate inside the battery. If the heat is not removed in time, the temperature of the battery pack will rise sharply. Especially for a large-capacity battery pack, the heat release is usually higher and due to the need to meet the energy density It is easier to accumulate heat, which will lead to thermal runaway, which will further cause the battery to release gas, smoke, and leak, and may even cause the battery to burn. On the contrary, when the battery pack is in a low temperature environment, it may shorten the life and weaken the discharge capacity. Therefore, the temperature management of the power battery is particularly important; the patent application number CN201110041307 discloses a method for adjusting the temperatu...
