Battery booster system

摘要

A battery booster for a wheelchair electrical system powered by two twelve volt batteries that includes a twelve volt power socket of conventional standardized configuration for receiving battery-boosting power from a twelve volt power source such as a vehicle cigarette lighter. Power received at the socket charges the wheelchair batteries either through a switch for selectively connecting the batteries in series for operation or parallel for charging, or through a timer and relay arrangement for automatically charging the batteries in alternating sequence.
