What to Do When an Electric Vehicle Has Low Voltage?
2 Answers
Prolonged inactivity may trigger a low voltage warning, as the battery discharges whether in use or not. Simply fully recharge the battery. Inspect the battery circuit for any loose connections and secure them properly to prevent insufficient circuit voltage. Check the battery's condition to determine if electrolyte replenishment is needed. Refill the electrolyte or replace the battery entirely.
Last time I rode my little e-bike, it under-volted, which was really frustrating. The bike suddenly stalled, and the dashboard showed low voltage. I first tried plugging in the charger to see if it would charge, but it still didn't work. The battery might be old and drained. I quickly opened the toolbox and used a multimeter to measure the battery voltage, finding it was significantly below the normal 12 volts. It could be that the battery has been used for too long or that the charger has issues. I first pushed the e-bike to a safe spot to avoid blocking the way. Then, I checked all the wire connections to ensure there were no looseness or corrosion. For emergency measures, I could borrow a power bank from a friend or use a spare battery. But ultimately, I'll need to go to a professional shop to replace the battery or inspect the charging system to prevent safety hazards. Regular battery maintenance is key to extending its lifespan—don't wait until it fails to regret it.
