I am doing some research as we would like to add LiPo auxiliary battery systems to a new emergency vehicle. We want to keep it simple. It would run warning lights, siren, mobile radio, and laptop. The main source of charging would be off the alternator but we would want to have an inverter/charger as well. I am hoping someone could help me understand what I need.
Thanks
Ive got a similar, small system installed in my work van. However, if i would rebuild the system today i would use the new Lithium SuperPack NGs which avoids the need for a VE.Bus BMS and an external Shunt. Makes the system much simpler but as reliable.
You can use the EFS output to control chargers or loads, but you dont need to. The internal BMS can switch charging or discharging independently. But if its easily possible to do so, in this case by using the Orions remote On/Off i probably would use it too. Setting correct charge voltages is the first barrier to keep a battery safe, the BMS switching off should be the last.
The main switch is kind of the same story, the battery has an On/Off button that switches the battery through the BMS, so an external switch is redundant.
Thank you again this has been super helpful.
