BAT104-NiCd - 600mAh NiCd PC/104 PSU Backup Module

8.4V @ 600mAh NiCd Batteries for Tri-M Series Power Supplies


The BAT104-NiCd creates a complete UPS system by plugging directly into the bottom of the HESC (including the V5SC-SER) Vehicle Power Supplies. The BAT104-NiCd includes seven 600ma-hr NiCd batteries for a total of 5 watt-hours of power. Therefore a BAT104-NiCd can supply backup power for up to sixty minutes to a 5 watt load.

The BAT104-NiCd includes Mosfet transistors for preventing deep discharge occurrences during extended power outages. The Mosfet transistors electrically isolate the BAT104-NiCd from the HESC whenever the BE output of the HESC is de-asserted (pulled to 5V).

The BAT104-NiCd 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.
