Abstract
A battery control circuit includes an electronic switch, first and second diodes, and first and second batteries. A positive terminal of the first battery is connected to a positive terminal of the second battery through the first diode. A negative terminal of the first battery is connected to a positive terminal of the second battery through the electronic switch, and connected to a negative terminal of the second battery through the second diode. When the electronic switch receives a first control signal, the electronic switch is turned on, the first and second diodes are turned off, and the first and second batteries are connected in series. When the electronic switch receives a second control signal, the electronic switch is turned off, the first and second diodes are turned on, and the first and second batteries are connected in parallel.
