I am using a ChargePoint model CPF25 charger capable of over 7kW, but delivering much less. Sometimes it delivers 18-19 mi/hr while other times it's only 14. Has anyone seen this variation and found a way to motivate the vendor to fix it?
The lower charge appears when my ms slowly ramps up charge current and detects a large voltage drop. A warning message appears about a defective extension cord, but I don't have one. Instead of receiving 32 amps, the ms limits charging to 24 amps and delivers only 14 mi/hr. No one else is charging near me.
At a 1 amp charge (light load), voltage is 209. As current ramps up, voltage steadily declines to 194. This is an indication of excessive resistance somewhere in the line or connections. Is a 15 volt drop normal; acceptable to NEC?
I'm not the charger operator so am getting a deaf ear from ChargePoint Support.
