Are you sure it's unhealthy if you're already charging this slow? I'd expect 12 kW to still be below the slow part of a fast charge.
- greenavocado 2y agoI'm sorry, you're right about 12kW charging. The battery pack is made up of 4,416 individual cells. The cells are arranged in series to achieve the required voltage. If there are 96 cells in series, the pack would have a nominal voltage of around 400 volts (since each cell has a nominal voltage of about 4.2V when fully charged). The pack has multiple strings of these 96-series cells connected in parallel to increase capacity. 12kW/400V = 30A. 30A/(46 parallel strings) = 0.652A per cell or 652 milliamps. This is quite a slow and healthy charging speed.
