PURPOSE: A battery charger by an inductive power can control charge of each batteries. CONSTITUTION: In a self stabilizing bank or monoblock a primary inductive conductor is energized using all the cells, individual cells are separately monitored by control means and any below average cell can be individually charged from the inductive conductor, thus correcting between cell variations. Battery banks may be charged using multiple isolated position tolerant pickups independently controlled according to the condition of the connected battery unit and by overall commands communicated over an isolated link. Loosely coupled inductive power for charging batteries is rectified from a first power pickup winding and the resulting current source is connected to a battery unit(309). Each current source is controlled by shorting a second resonant winding(304). The battery unit may be a single cell. The charge in all cells within a bank can be held within 30% to 70% of full charge and prevented from drifting towards full or empty during repetitive charge and discharge times. |
