Charging Curves And Peak Charge Rates: Why It Matters
But if you do plug into a 150kW unit on 5%, the car will quickly ramp up to its maximum, or ''peak'' rate. But you won''t stay at 120kW all the way to 100%.
Here''s a video of charging from 10-88%, followed by a graph of a different charging session from 80-100%. The BMS was cold gating at the start (in the words of Bjorn Nyland), since temps in Chicago have dropped somewhat. Setting the charger as the destination in the nav didn''t preheat the battery.
This setting is intended for flooded tubular plate traction or OPzS batteries. During absorption the voltage limit increases to 2,83V/cell (34V for a 24V battery) once the charge current has tapered down to less than 10% of the set maximum current. Not adjustable with DIP switches. See ''tubular plate traction battery charge curve'' in ...
