Embodiment Construction

[0042] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0043] figure 1 It is a block diagram of a battery temperature control system according to an exemplary embodiment. refer to figure 1 , through the three-way 6, the three-way 7 and the double-way 11, the on-off of the three coolant circuits connected to the battery pack 10 can be controlled. These three circuits include: connecting a heating device (for example, a thermistor (Positive Temperature Coefficient, Abbreviation: the heating circuit of PTC)) 9, the cooling circuit connected to the battery radiator 2, and the cooling circuit connected to the heat exchanger 8. In addition, the radiator 1 and the compressor 3 connected to the heat exchanger form a r...

Abstract

The present invention relates to a battery temperature control method and a battery temperature control apparatus. The battery temperature control method comprises: acquiring the lowest temperature and the highest temperature from the temperatures of a plurality of temperature collection points of a battery pack; and controlling the temperature of the battery pack according to the lowest temperature and the highest temperature. According to the present invention, the battery pack is subjected to temperature control by using the corresponding measures according to the lowest temperature and the highest temperature in the temperatures of different temperature collection points of the battery pack, such that the operation is easy to achieve; and the temperature of the battery pack can be controlled within the reasonable range, the energy consumption can be reduced as much as possible, and the temperature control efficiency can be improved.

Description

technical field [0001] The present disclosure relates to automobile battery technology, in particular, to a battery temperature control method and device. Background technique [0002] The power of new energy vehicles is supplied by the battery system, and the performance and life of the battery system are greatly affected by temperature. At low temperatures, the battery may reduce power or stop working, and the internal resistance of the battery will increase, thereby reducing work efficiency. and reduce battery life; as the temperature rises, the internal resistance of the battery decreases, and the power returns to normal levels; when the temperature of the battery is too high, the battery will also reduce power or stop working, and it will also increase the risk of battery thermal runaway, reducing Battery Life. In addition, the battery system is composed of multiple cells, and the temperature of each cell is different, so that the aging degree is different, and the ove...
