Systems for protecting cells and batteries with lithium-ion batteries. Part 1

The requirements of regulatory documents on the implementation of the safe operation of batteries and rechargeable batteries are presented. A generalization of modern methods for ensuring the protection of lithium-ion batteries was carried out. Various systems of protection of single batteries for the prevention and elimination of emergency modes of operation are considered. A description of the principles of operation of protective devices and examples of their implementation in practice is given. The principle of operation of the electronic protection system in the form of small printed circuit boards built into the battery case is shown.
