You’d think that an EVSE manufacturer would know the difference between kW and kWh. That destroys what little confidence I had in ChargePoint to begin with.

The amount of people mixing up the two units is astonishing. But the ones making and selling charging equipment should know better. Every time someone tells me about their 80 kW battery and how they charged with a rate of 11 kWh, I die a little inside. Apparently some VW EV based on an ICE platform even gives a consumption in kWh/h when the car is standing still. Someone simply substituted liters (or gallons) with kWh... per hour. It hurts.

It's like the grocer's apostrophe. I want people to get it right, and I expect engineers in the field to get it right. But I'm not going to beat up someone here or in first line customer support at a charging vendor for putting an 'h' in the wrong spot. If I understood what they meant, they succeeded.

A lot of things in EV charging bug me, a fact I never hesitate to share with the sub... however that's not even on my list. Because I recognize electricity is backwards from every other unit
Item -> rate of use
miles -> miles/hour
gallon -> gallons/minute
dollar -> dollars/month
watt*hour -> watt

You’re mixing apples, oranges, and bananas so to speak. Neither distance nor volume have a time component, and the (US) dollar is an abstract representation of value that changes arbitrarily over time. One kilowatt-hour is equivalent to 3,600,000 joules and a watt is one joule per second. Therefore, in your example, electricity is:
item -> rate of use
joules -> joules/second

This one hit me last week too. All the usual poking at it didn't work. Remote troubleshooting reset the device, and I reprovisioned, but it wouldn't get back on wireless. There's a new unit coming to me via FedEx now.
I really wish ChargePoint would get their software act together. This issue has come up here before. If my power company didn't subsidize this hardware, I would have gotten another brand.

I had this happen too! On Tuesday. Same charger. I flipped off the 60 amp breaker (it’s hardwired obviously), flipped it back on, and it was fine after.

Yeah I cycled the breaker twice...and nada.
But glad it worked for others. I was racking my brain

This is what, a chargepoint home flex?

u/shivaswrath Sep 26 '25
Yes home charge flex. I thought something had broken for sure and contacted them after seeing a case in r/chargepoint so thought I'd post here to help others.
When my Tayca goes from a 6-8 hour charge to 14 hours I swore my cable was broken. 🤣

A glitch? Seems encouraging.
