A new study led by Berkeley Lab reveals surprising clues into the causes behind the rare event of a lithium-ion battery catching fire after fast charging. The researchers used an imaging technique called "operando X-ray microtomography" at the Advanced Light Source to probe lithium-graphite battery materials at high resolution.
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 Short circuits, arcing, improper wiring, and outdated equipment anywhere in the system can all lead to fires.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.
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.
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.
Here are the facts. By Vivek Saini Recently, a video clip that went viral on social media platforms has sparked widespread concern and curiosity about EV batteries. The video shows an individual bringing supposedly an EV battery into a lift following which the battery catches fire leading to a blast.
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.
