How does charge control limit the charging voltage?
Charge control by sensing the absolute voltage rise is strongly discouraged by Gates Energy Products. Rate-of-voltage-change (dV/dt) charge control limits overcharge by terminating fast charging at some point where the voltage begins to rise prior to Point 2 in Zone C of Figure 3-54.
Why is my car charging system not working?
