BAT-SLA(25/45): SLA Battery Backups

Overview

Sealed Lead Acid Backup for Smart Charging Power Supplies

The BAT-SLA series includes the BAT-SLA25 and the BAT-SLA45. The BAT-SLA battery backup units have PC/104 footprint and create a complete UPS system by plugging directly into the bottom of the HESC (including the V5SC-SER) Vehicle Power Supplies. Each BAT104-SLA includes five SLA batteries for a nominal backup voltage of 10 volts. The BAT104-SLA25 utilizes 2.5Ahr batteries for a total of 25 watt-hrs backup and the BAT104-SLA45 utilizes 4.5Ahr batteries for a total of 45 watt-hrs of backup power. Therefore a BAT104-SLA45 can supply backup power for up to sixty minutes for a 45 watt load.

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

The BAT104-SLA has a current activated fuse for protection against shorts on the battery output.

A digital I2C temperature sensor provides temperature feedback for ambient temperature measurement which can be read by the HESC.
