Understanding the fire protection problem with EV charging has two facets to consider: one, the charging station; and two, the EV itself (specifically, the BESS in the EV). In most fire incidents, the fire will likely have originated because of a fault in one of these two areas.
Specifically, the charger faces the same fire risk as does any electrical device. Short circuits, arcing, improper wiring, and outdated equipment anywhere in the system can all lead to fires. Defects in any of the safety equipment can also lead to fires.
According to the investigation report, it is determined that the cause of the fire accident of the energy storage system is the excessive voltage and current caused by the surge effect during the system recovery and startup process, and it is not effectively protected by the BMS system.
The charger manufacturers also require that the installation be in accordance with the National Electric Code (NEC). The referenced certifications are meant to require/impute safety to the charging system with a particular emphasis on protecting against a fire. This is because fire is the most significant hazard during EV charging.
Charging stations consist of the charger, the cable, and the connector that plugs into the vehicle. To be sold in the U.S., the equipment must meet Underwriters Laboratories (UL), International Electrotechnical Commission (IEC), and Federal Communication Commission (FCC) requirements.
Clearly, there is a need to provide fire protection at EV charging stations. There are several factors to consider when choosing a fire protection system for this application. EV charging stations can be installed almost anywhere. Large-scale, filling-station-style EV charging stations are beginning to become commonplace.
