Background

Research shows that the optimal working temperature of the lithium battery is about 18-25 ℃, and in the temperature range, the performance of the lithium battery is the most stable, and the service life of the lithium battery is the longest. When the temperature is lower than or higher than the temperature range, the performance of the lithium battery can be changed to a certain extent, and the service life of the lithium battery is even influenced. The data show that the lithium battery is charged and discharged for more than 50 times continuously at the charging speed of 1C in the environment of more than 55 ℃, the battery capacity is obviously reduced, and the service life of the battery is correspondingly shortened. When the ambient temperature exceeds 60 ℃, the battery may be overheated and burned due to excessive temperature rise, thereby causing explosion risks. The parallelly connected or series connection of current group battery owing to be in the same place more lithium cell electricity core, when carrying out the work, the electricity core produces the heat and can superpose each other, and the heat if discharge in time can not lead to the battery capacity of group battery obviously to descend, battery life shortens, so designs a group battery ten minutes necessity that has good radiating effect.
