Description

technical field [0001] The invention relates to the technical field of lithium ion battery heating, in particular to a heating device capable of collecting the voltage of the lithium ion battery. Background technique [0002] Most new energy vehicles use lithium-ion batteries to provide power, but because the electrolyte of lithium-ion batteries is an organic solute, the discharge capacity at low temperatures is very poor. However, some of the sales markets that new energy vehicles face belong to cold regions. If the temperature is too low and is lower than the operating temperature range of lithium-ion batteries, the vehicle will not be able to start. Heating device for ion battery heating. Contents of the invention [0003] The present invention aims to solve the above-mentioned deficiencies in existing lithium-ion batteries used in new energy vehicles, and provides a battery connection module that can sequentially connect the single cells in the lithium-ion battery in ...
