A battery management system comprises: a circuit path electrically coupling a battery and a load; a backup storage device; a first switch connecting the battery and the backup storage device; a second switch connecting 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 executes a program 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 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.

A method of forming an ordered nanorods array in a confined space is used to form a high surface area device where an ensemble of parallel trenches has micrometer dimensions for the width and depth of the trenches, which are decorated with crystalline nanowires radiating from the sidewalls and bases of the trenches. The high surface area device is formed by depositing a conformal crystalline seed coating in the trenches, forming microchannels from these trenches by placing a barrier layer on the open surface of the trenches, contacting the conformal coating with a crystal precursor solution that is caused to flow through the microchannels. In an embodiment, a very high surface area electrode is constructed with ZnO nanowires radiating from the sidewalls and base of trenches formed on a silicon substrate. The device can be a dye-sensitized solar cell.
