Battery troubleshooting example
Below is the battery tro ubleshooting example.
Exa mple 1:
Due to the poor perfo rmance o f the electric vehicle and the battery is suspected to be the cause, the battery charger is
inspected. When the battery is fu lly charged, the reading on the ammeter o f the battery charger is 8.0A. The charging
vo ltage inspection is condu cted and the resu lts are recorded.
