Description
Nickel Metal Hydride battery backup for HESC104 or HESC-SER power supply
The BAT104-NiMh creates a complete NiMh UPS system by plugging directly into the bottom of the HESC (including the V5SC-SER) Vehicle Power Supplies. The BAT104-NiMh includes seven 2300ma-hr NiMh batteries for a total of 19.3 watt-hours of power. Therefore a BAT104-NiMh can supply backup power for up to sixty minutes to a 19.3 watt load.
The BAT104-NiMh includes Mosfet transistors for preventing deep discharge occurrences during extended power outages. The Mosfet transistors electrically isolate the BAT104-NiMh from the HESC whenever the BE output of the HESC is de-asserted (pulled to 5V).
The BAT104-NiMh has both a thermal fuse and a current fuse for protection against overcharging, and shorts on the battery output.
A digital I2C temperature sensor provides temperature feedback for charge termination, which can be read by the HESC.
