Battery Isolation Manager

The Battery Isolation Manager (BIM)

isolates the two battery systems, Chassis & Coach, in a Motorhome. This prevents loads in one system from discharging both. It also connects the two battery systems together during charging. Both batteries are charged if either is being charged. The Coach Battery is charged while driving down the road, and the Chassis Battery is charged while plugged into Shore Power at a campground.

Product Features and Function

Operation: The Battery Isolation Manager (BIM) monitors the Battery Voltage of both the Chassis and Coach Batteries over long periods of time. If it senses a charging voltage, it connects the two batteries together. If the charging system is drastically overburdened, the batteries will be isolated, however, if the BIM sees a long-term charging of both batteries it will allow the batteries to remain connected and allow the charging system to do its job. Once the batteries have reached a Float Charge state for one hour, the BIM will isolate the batteries to prevent overcharging, and will only reconnect the batteries for charging if one of the Batteries drops to approximately 80% charge and the other is being charged. This long-term monitoring of the batteries prevents the annoying relay clicking that exists in simpler Isolation Modules today.

The BIM does not guarantee 100% battery charge but prevents harmful battery charge levels.

Note:

The Battery Isolation Manager goes between the Chassis and Coach Batteries to maintain both batteries when either one is charging.
