1000W On-Board Battery Charger for Vehicles in Cold Climates

Absopulse Electronics’ BCP 1K-27CB series is a rugged industrial quality battery charger specifically designed to assist vehicle warm-up during extremely cold weather. Typically permanently installed on a vehicle, this charger is activated on days when the ambient temperature drops below 0VC. This charger is suitable for installation on buses, trucks and other vehicles.

This charger accepts 115Vac nominal input (100V-132Vac range) and delivers 27.5Vdc at 36A for float charging the 24Vdc battery, custom input and output options are available on request. In addition to maintaining the battery condition, it provides sufficient power to keep essential on-board equipment and heater fans operational during the vehicle warm-up period.

The BCP 1K-27CB operates at full specification over a -40VC to +50VC cold plate temperature range cooling is by conduction via baseplate to chassis wall and by additional convection. This charger is fully ruggedised and conformal coated and meets SAE International J1455 and IEC61373 Cat 1 A&B shock and vibration standards as a minimum. The enclosure measures (5.5in x 6.5in x 14in) and weighs approximately 10 pounds.

This battery charger is based on field proven technology with a track record in transportation environments including railway, trucking and aviation. The absence of fans, large design headroom, and the use of components with established reliability result in a high MTBF. Protection includes inrush current limiting, over-voltage protection, short circuit protection, and self-resetting thermostat for thermal protection.
