The BAT-NiMh45 creates a UPS system by plugging directly into the bottom of the HESC (including the V5SC-SER & HPSC) Vehicle Power Supplies. Each BAT-NiMh45 includes seven 4.5Ahr "A" size batteries for a nominal backup voltage of 8.4 volts. The BAT-NiMh45 can therefore supply a total of 37.8 watt-hrs of backup power and supply backup power for up to sixty minutes for a 37.8 watt load.
The BAT-NiMh45 includes Mosfet transistors for preventing deep discharge occurrences during extended power outages. The Mosfet transistors electrically isolate the BAT-NiMh45 from the HESC whenever the BE output of the HESC is de-asserted (pulled to 5V).
When ordered with the Real Time Clock option, the BAT-NiMh45-RTC can "awaken" from Sleep Mode at a programmed start-up time. A momentary "dry" contact on CN3 can also override the Sleep Mode and awaken the BAT-NiMh45-RTC. Tri-M Power supplies supporting the HESC-UPS18 firmware can program and read the RTC on the BAT-NiMh45-RTC. Tri-M Power Supplies with HESC-UPS firmware can use the BAT-NiMh45 for a UPS system, but without RTC support. Refer to section "Configuration and Installation" for listing of compatible power supplies and firmware support.
The BAT-NiMh45 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.
