Abstract

One general aspect includes a battery switch testing method, the method implemented in a system including first and second batteries and a controller, the method including: (a) monitoring, via the controller, electrical properties of the first battery; (b) when the electrical properties of the first battery falls below a threshold value, via the controller, opening a switch of the first battery; (c) closing, via the controller, the first battery switch; (d) monitoring, via the controller, electrical properties of the second battery; (e) when the electrical properties of the second battery falls below a threshold value, via the controller, opening a switch of the second battery; and (f) closing, via the controller, the second battery switch.
