When an EV battery reaches 0%, its performance declines until it stops. The vehicle enters a low-power or “limp” mode, where it can no longer operate. This is what happens when an EV battery hits 0%:

1. Reduced Performance: If the battery faces 0% charging more frequently it reduces the battery capacity. As in the mobile phones if we discharge battery until it reaches 0% or gets switched off the next time we charge it, it depletes faster than before, same happens with EV battery.

2. Limited Functionality: Some EVs may deactivate certain features or systems to conserve remaining battery power. This can include reducing heating or air conditioning functions, limiting power to non-essential accessories, or dimming interior lights.

3. Warning Indications: Most EVs have warning systems that alert drivers when the battery charge is low. These warnings may appear on the instrument cluster or infotainment display, indicating that the battery is nearing depletion and urging the driver to find a charging station.

4. Reduced Range: The vehicle’s estimated range decreases as the battery charge approaches 0%. Drivers should pay close attention to range estimates and plan their routes to avoid running out of power before reaching a charging station.

5. Complete Shutdown: When the battery charge reaches 0%, the EV will come to a complete stop. To prevent further battery depletion or damage, the vehicle enters a “safe mode” or “power-off” state. The driver must pull over safely and call for assistance, as the vehicle cannot be restarted without recharging the battery.
