18650 Lithium Ion Battery SAFETY Problem Generated From Electric Bus Fire Incident

- Sep 24, 2017-

The findings show that "overcharge" results in a runaway thermal battery, electrolyte leakage, and a short circuit that causes a fire. Specifically, battery management system control strategy deficiencies, charging system imperfect and monitoring data are not taken seriously, car charger - background monitoring lack of safety protection system is the reason for this accident.

since 18650 battery applied in electric vehicals, especially the cars, topic concerning SAFETY is emerging to the public with hot topics. In writer's opinion, lithium ion battery safety should conhcern main reasons:

  1. shock resistance

  2. big current working ability

  3. heat dissipation

  4. BMS control
