Systems for protecting cells and batteries with lithium-ion batteries. Part 2

The requirements of regulatory documents for the implementation of the safe operation of lithium-ion batteries and storage batteries are presented. A generalization of modern methods for ensuring the protection of lithiu m-i on batteries has been carried out. External systems for protecting cells and battery packs for the prevention and elimination of emergency and fire hazardous modes of operation are considered. A description of the principles of operation of protective devices and examples of their implementation in practice is given. Examples of the implementation of external electronic protection systems in the form of separate printed circuit boards (BMS) and non-electronic ones — in the form of various cooling systems (BTMS) and fuses are shown.
