Hello from ChargePoint!

How accurate is the kWh reported by a Chargepoint station?

Is it kWh delivered to the car, or is it adjusted for some charging efficiency estimate? If adjusted, by what percentage?

My *guess* would be that it is the electricity delivered to the vehicle, since that is what you are buying ...

How could they guestimate the efficiency since that is determined by the charger in the vehicle?

I don't care to guess. So I ask.

Also, I'd guess that the kWh is plus or minus a few percent. But how many percent, I don't care to guess.

Hi!
All of our products are accurate to less than 1 watt. It's a measure of how much “power” has passed through the station, not necessarily how much your battery “charged up”. For example, on a hot day, your car may have to run the cooling fan to cool the battery, which will show up on the total kWh reported, but not necessarily mean that your battery stored that power. The reported kWh is the total energy that you drew during the session.

Thanks.

Since the Chargepoint app can see SOC%, why isn't there a setting to terminate charging at certain SOC% ? may be there is, and I just haven't figured it out ?
Thanks

If you're using a public ChargePoint station you should receive a notification when you're full (https://www.chargepoint.com/support/driver-faq/#q9). This lets you know it's time to head back, unplug, and move your car to free up that space for others , vs. the ChargePoint Home which lets you stop from the app. However, I've heard from other MyChevyBolt members that they'd like a button to stop charging from the app, too, even at destination chargers (perhaps they have similar needs for stopping by % like yours), so I've shared this feedback with the team previously. I really appreciate your suggestions because it's always helpful for our team to know what features you'd like to see added to the app!

Hey Chargepoint!

When are you guys gonna get the Delta AC Mini's certified for your network? I have four of them screwed to a wall, RFID enabled, powered and signed in and on WiFi in Los Angeles and all I need to do is enter the OCPP server addresses and credentials. Can I be your guinea pig?

Greenlots uses them, they couldn't be that horrible, but me and my wife are the only people I know with greenlots FOBs.

Thanks!

I'm a GreenLots customer, but don't have a FOB - I always enable via the phone app.

Having a way to terminate charge (with Home Charger) via a SOC % setting would be an awesome enhancement, mainly to prolong battery life. While the Bolt has Hilltop mode, which stops charge at 92% or so; I would rather stop ~50%-75% for most days (particularly when it's over 100F) since I don't need the full 200-mile every day.

Tesla vehicles have a sliding setting to stop charge at certain %SOC for example. The Chargepoint app already has the capability, just need a few line of codes. Plus, it can be used with other vehicle to Hilltop mode.

We live at 2200-ft, and the other two EVs, Volt and iMiEV, can use the Hilltop mode.

Thanks
