A kind of lithium-ion battery temperature control method

Abstract

The invention discloses a temperature control method which can be effectively applied to part of soft-packaged lithium ion batteries. A temperature control solution effective in design can be analogized by adopting the method. The method mainly comprises the following steps that 1, a plastic support is firstly adopted to fix a lithium ion battery, and secondly lamination is performed by utilizinga heat conducting assembly and a corresponding housing zone between pole lugs in the lithium ion battery and an electrode material; then, the heat conducting assembly is connected with a temperature control assembly; 2, the temperature control assembly controls the temperature of the lithium ion battery through the heat conducting assembly according to the battery cell temperature of the lithium ion battery, performs heating and heats the lithium ion battery through the heat conducting assembly when the battery cell temperature of the lithium ion battery is lower than designated temperature, and performs cooling and cools the lithium ion battery through the heat conducting assembly when the battery cell temperature of the lithium ion battery is higher than the designated temperature.

Description

Technical field [0001] The invention relates to the field of temperature control of lithium batteries, and in particular to a method for temperature control of lithium ion batteries. Background technique [0002] Batteries include: thermal battery cells, battery packs, and lithium-ion batteries. The batteries may be in different working environments during use, and thus exhibit different performance. For example, under extreme conditions such as high temperature, low temperature, high voltage, high rate charging and discharging, battery overheating and other phenomena may damage the reversibility of the battery, and even directly shorten the battery life and affect the operating cost of the battery module. Therefore, the temperature control of the battery is a problem that must be faced in the normal use of the battery. The traditional temperature control method is to control the temperature of the cell surface. Although the temperature control effect is stable, the overall stru...

Problems solved by technology

The traditional temperature control method is to control the temperature on the surface of the battery cell. Although the temperature control effect is stable, the overall structure is huge and complex due to the large contact area. Therefore, it is necessary to provide a simple and effective temperature control method to reduce system costs.
