Hi, on the Bosch Powertube 625 battery, when its being charged does it require a specific charger to send it a CAN command to allow charging ?
The reason I ask this is that we want to fit a " bottle battery " as a range extender ( simple 10S1P ) the 625Wh is just a tad short on range at times. A theoretical plan would be to limit the bottle battery to say 5A and then just plug the battery into the charge port. As the main battery becomes depleted the bottle battery will charge at 5A's. That may not be enough to maintain the main the battery, but enough to charge some extra range if say you stop for a coffee or whilst using less then 5A's which maybe more often than you think.
OK thats in theory but I know Fazua needs a CAN signal to allow charging, has Bosch done the same ? Also what are the effects on the BMS if you are charging whilst also discharging ? Lots of unknowns here I think but hoping someone will know.
