Experience perfect control and reliability with Volvo Penta’s new comprehensive Battery Management system – a safe and easy-to-use control system for the boat’s batteries. With the Battery Control Module (BCM) acting as a hub the boat’s entire electrical system will be both more reliable and easier to monitor. You’ll need one for each engine. The BCM contains a number of inputs, outputs and built-in electrical components that handle the power supply to the engine and accessory consumers on-board. Basically the system consists of one or more BCM-units to which batteries and power consuming devices are connected. Batteries may be start- or consumer batteries. power consumers may be start motors, instruments, bow thrusters and different accessories. The battery supply switches for the consumers can be operated locally on the BCM, via the Battery Management Display or via an external button panel.
Each driveline’s start battery/engine shall have at least one BCM connected to ensure redundancy and maximum availability.

The BCM is the heart of the system
The BCM contains two battery channels with main switches (300A continuous, 600A peak). One Cross-Over switch, enabling one battery to borrow energy from the other. All three switches are of solid-state technology ensuring optimal durability and reliability with minimal voltage drop without relays or moving parts. The BCM also contains a main fuse holder. Battery charge distribution, the engine alternator is connected to the unit that automatically distributes the energy to both battery groups. Battery Isolation, ensures that the battery channels are isolated to prevent drainage. There are two constant outputs, 20A. To provide easy installation of constant loads such at bilge pumps that need access to power even when all main switches are off.
