1. A battery management system, comprising:
a first circuit path electrically coupling a battery and a load;
a backup storage device;
a second circuit path electrically coupling the battery and the backup storage device;
a first switch connected in the second circuit path between the battery and the backup storage device;
a third circuit path electrically coupling the backup storage device and the load;
a second switch connected in the third circuit path between the backup storage device and the load;
a sensor for measuring a temperature of the battery; and
a controller in electrical communication with the first switch, the second switch, and the sensor, the controller executing a program stored in the controller to:
(i) activate the first switch to connect the battery and the backup storage device for charging the backup storage device for a charging period of time with power provided by the battery based at least in part on the temperature of the battery meeting a threshold, and
(ii) activate the second switch to connect the backup storage device and the load for providing power to the load from the backup storage device after the charging period of time has expired.
