The BMS is designed for use with Victron Lithium Iron Phosphate batteries. Its function is to manage the battery bank and prevent overcharging or over discharging.
Shuts down or disconnect loads in case of imminent cell under voltage, -
Reduces charge current in case of imminent cell overvoltage or over temperature (VE.Bus products only)
Shuts down or disconnects battery chargers in case of imminent cell overvoltage or over temperature.
The operating voltage range of the BMS is from 9 to 70V DC.
The VE.Bus BMS connects to a MultiPlus, Quattro or Phoenix inverter with a standard RJ45 UTP cable.
The Load Disconnect output can be used to control the remote on/off of a load or electronic relay
The Charge Disconnect output can be used to control the remote on/off of a charger, load relay or battery combiner
In the very basic wiring diagram below there is a generic battery charger with a charge relay to turn it off when necessary and a load relay that turns off when the battery is getting over discharged. This diagram is the most basic one and doesn't use the ability of the BMS to communicate on the VE Bus network
