Patent abstract
A device and method for equalizing the charge among a plurality of batteries redundantly driving a motor. The batteries are coupled to the motor through isolated windings and to each other through the drive shaft. The device senses the charge of the batteries and then controls the current from each of the batteries to its respective winding to equalize the charge. Related methods are provided to maximize the speed limit of a balancing transporter.
