APPARATUS FOR AUTOMATICALLY SWITCHING AND CHARGING MULTIPLE BATTERIES
First Claim
1. An apparatus for automatically switching and charging a first battery and a second battery, the apparatus comprising:
- a charger unit;
an output port configured for connecting to a load;
a first control switch connected between the charger unit and the first battery;
a second control switch connected between the charger unit and the second battery;
a first output switch connected between the first battery and the output port;
a second output switch connected between the second battery and the output port;
a main control unit connected with the first and second batteries, the first and second control switches, and the first and second output switch modules; and
a power source module configured for providing power to the main control unit and the charger unit;
wherein;
the main control unit is configured to monitor the output voltages of the first and the second batteries, and if the output voltage of the first battery is lower than that of the second battery to turn on the first control switch and the second output switch and turn off the first output switch and the second control switch so that the first battery is being charged by the charger unit and the second battery is providing power to the load connected to the output port.
