Abstract
The battery system includes a battery pack having a plurality of power sources arranged in parallel groups that are connected in series. Each parallel group includes a plurality of power sources connected in parallel. Each power source includes a battery. The system also includes electronics configured to repeatedly charge the battery pack according to a charging protocol. The charging protocol is configured such that the voltage of any one battery in the battery pack does not exceed its maximum operational voltage after failure of a battery in the battery pack.
