EVs use redundant systems to prevent which type of issues from occurring?

• A. Battery swelling
• B. Shock and fire hazards
• C. Short-circuit events
• D. Power loss during cold

Answer: (B)

Redundant safety systems in EVs are built to prevent electric shock and fire hazards by maintaining proper isolation and a safe shutdown even if a component fails. If one path or device in the high‑voltage system falters, a backup keeps protection intact—for example, keeping the high‑voltage isolation barriers effective, ensuring the battery disconnect can still engage, and triggering emergency shutdown when needed. This design minimizes the chance that a fault could expose occupants to live voltage or lead to a fault energy release that could ignite a fire. Other issues like battery swelling, short circuits, or power loss during cold can arise from different causes and aren’t the primary focus of safety redundancy. The redundancy specifically targets stopping dangerous outcomes for people and property by ensuring the system remains in a safe state even in the face of component failures.
