Stranded energy from a damaged battery can release voltages in what range?

• A. 12 V DC to 24 V DC
• B. 100 V DC to 800 V DC
• C. 1000 V DC to 2000 V DC
• D. 50 V to 150 V

Answer: (B)

Stranded energy from a damaged battery can release voltages in the hundreds of volts because traction batteries in electric vehicles store a large amount of energy at high voltage. Modern EV/HEV battery packs commonly operate around 400 V nominal, with newer designs reaching up to about 800 V. That makes the range 100 to 800 V DC a good general description of the voltage you could encounter if a high-voltage pack is damaged. The lower ranges (12–24 V, 50–150 V) are typical for standard low-voltage automotive systems, not the high-voltage traction packs. The higher range (1000–2000 V) is not representative of most passenger EVs and would indicate an uncommon or specialized system. So the correct range reflects the typical high-voltage energy available in damaged EV batteries.
