Said electrical circuit comprises a ripple generator arranged to produce an electrical ripple current, a first ripple injector () to be arranged on a positive power line to the battery, said first ripple injector being arranged to transfer said electrical ripple current to said positive power line, and a second ripple injector () to be arranged on a negative power line to the battery. Said second ripple injector is arranged to transfer said electrical ripple current to said negative power line. Said first and second ripple injector are arranged to operate in a differential mode, e.g. opposite sign on injected current.
