The Wolf at the Door [Arc Flash Hazards and Electric Vehicle Batteries]
Electric vehicles (EVs) are powered by high-voltage battery systems that can present a significant arc flash hazard. An arc flash is an electrical explosion that occurs when current flows through the air between two conductive objects, creating a high-temperature plasma that can cause severe burns, blindness, or even death.
Electric Vehicles: High-Voltage Tools & Equipment
In addition to special safety gear, working on HV systems requires specific and specialized tools as well. Grabbing any off-the-shelf screwdriver or wrench is not going to cut it when performing work on an HV system. Specialized tools that are insulated for high-voltage are necessary. These specialized tools are typically rated for up to 1,000 volts and are either made out of a non-conductive material, such as plastic, or may be coated to insulate it from electricity.
