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.

First Claim:
Show all 9 claims		     1. A method for equalizing the charge between a first battery and a second battery, the first battery providing a first current to a first winding of a motor and the second battery providing a second current to a second winding of the motor, the motor supplying power to a mechanical device, the method comprising:

a. determining a value of a parameter of the first battery and a value of the parameter of the second battery; and

b. adjusting the first current and the second current to reduce a difference of the value of the parameter of the first battery from the value of the parameter of the second battery.
