Abstract

The invention discloses a battery pack temperature control system, which comprises a heat conduction and insulation part, a heat conduction part and a temperature control part, wherein the heat conduction and insulation part is used for being filled among monomers in a battery pack to implement the conduction of the heat of the battery pack; the monomers in the battery pack are arranged according to a predetermined arrangement rule; the temperature control part is connected with the heat conduction part, and is used for receiving temperature signals acquired by temperature sensors, analyzing the temperature signals according to a preset program to obtain an analysis result, choosing a control mode corresponding to the analysis result and controlling the operating state of the heat conduction part according to a control signal outputted by the control mode to control the temperature of the battery pack. The system can increase the efficiency, safety and cycle life of the battery pack. The invention also discloses a battery pack temperature control method.

Description

technical field [0001] The invention relates to the field of lithium batteries, in particular to a battery pack temperature control system and method. Background technique [0002] Batteries in electric vehicles, especially lithium batteries (including lithium cobaltate, lithium manganate, lithium iron phosphate, titanium lithium, ternary lithium batteries, etc.) have been used on a large scale, such as notebook computers, mobile phones, wind power, submarines, Electric bikes, electric cars, and more. Although lithium batteries have the advantages of high energy density, high specific power, and long cycle life, they also have defects such as long-term charging and discharging, which generate a lot of heat, cannot be charged at low temperatures, and are easy to burn when exposed to water. , For example, the battery pack used in electric vehicles is composed of hundreds of single cells. During operation, uneven heat accumulation will occur in the battery pack, which further ...
