Web23 de dez. de 2024 · Battery voltage may be higher than the rated voltage for a number of reasons, but typically it is due to one of two scenarios. The first is when a battery is overcharged or has been on a charger for too long. This can cause the battery to reach a higher voltage than its rated voltage. Web• Terminal Voltage (V) – The voltage between the battery terminals with load applied. Terminal voltage varies with SOC and discharge/charge current. • Open-circuit voltage (V) – The voltage between the battery terminals with no load applied. The open-circuit voltage depends on the battery state of charge, increasing with state of charge.
