How Many Miles Per Hour During L2 Charging?

[Bish322]

I've only had my Volt about a month and haven't really explored much in the way of Level 2 charging in public. I have a pretty simple question: Is there a standard "miles per hour" that goes back on the Volt during the 3-4 hours it would take to charge a fully depleted battery on the L2 chargers?

What I guess I'm asking is, specifically, if my total estimated range is ultimately going to be 42 miles will I gain 10-ish miles per hour over 4 hours, or, do I gain 30 of the 42 in the first hour and half and slowly add on the rest, etc.

Sorry if this is a duplicated question. I tried looking for other threads on the subject but couldn't locate one.

Fairly sophisticated question. You have it right, it's about 10 miles per hour. You're using more or less the middle part of the battery so the charge is fairly linear. Maybe it takes a little longer at the end as it top balances but not a big difference.

10 miles per hour. It also takes about .5 less KWH to charge using 240 versus 120v....

Thanks to you both!

Generally, you will be able to charge 1kWh in about 20 minutes at L2. How many miles you get for that one kWh depends on the conditions when driving. Worst case, I would think 10 miles per hour is about right. It can be as high as 15 given the best driving conditions.

I'm seeing about 10 miles/hour too, but this graph from my Blink dashboard shows that the charge rate tapers off at the end. It looks very linear the rest of the time.

Nice chart!

My Blink charge graph looks similar as well.

We could use a wallet size card showing the charge information for the 3 types of charging.
120 low-120 high -240 . miles added per time of charge and any other info you think might be of use,

The new car owners would find this a big help and for use by the backup drivers.

Sometimes I leave work (no charger at work) for lunch and get to charge during that time. I charge for about an hour and have been getting about 10 additional electric miles during this charge. This matches what others have been commenting as well.
