The number of protection chips for a single lithium-ion battery should be determined according to the number of lithium-ion battery packs and the number that should be used in series to protect the corresponding single lithium-ion battery's charge-discharge, over-current and short-circuit conditions. At the same time of charging protection, balanced charging is realized by protecting the chip and controlling the on and off of the parallel discharge branch switch device. This method is different from the traditional equalization charging at the charger end, and reduces the design and application cost of the lithium-ion battery charger.

　　Assembly process and method of soft-coated iron phosphate lithium ion battery

　　The assembly process and method of soft-coated lithium iron phosphate battery. Whether in the digital field or in the power application field, the soft-clad lithium iron phosphate battery is a very important technical route. The soft-pack battery actually uses aluminum-plastic film as the battery packaging material. The reason why soft pack batteries can be hot pack is because they use aluminum-plastic packaging film.

　　The soft-packed lithium iron phosphate battery is a liquid lithium-ion battery set on a layer of polymer battery, and the aluminum-plastic film packaging is used in the structure. In the event of a safety hazard, the soft-packed battery will only be happily cracked, so The overall safety performance is high, but with the development of the economy, the people of the soft-packed lithium-ion battery pack have also put forward higher requirements. The existing lithium-ion battery is complicated to install and the process is cumbersome and needs to be improved.
