The pack mounting to the chassis

Written by admin. Posted in Battery Pack

The pack mounting to the chassis begins with inserting the captive stainless nuts inside the chassis. You can see the three holes that were used to install them. 

The green lining is VHB acrylic foam tape, used everywhere in the auto industry. We will be leaving the top adhesive cover on since we do not need the high-strength bond to hold the pack_mounting_foot down since the bolts do that already. This will allow it to come off if needed. This makes a resilient pad that the weight of the pack and inverter sits on.

Battery update

Written by admin. Posted in Battery Pack

The electronics that monitor and control the battery cells, referred to as the BMS (Battery Management System), is currently under development for the BMW. This BMS design has the ability to be scaled to fit any application. The e-MotoCRF250R drive system will use the same BMS circuit boards in fact, integral to each module to eliminate exposed wiring.
