Also, how much should I expect this to take?

You...If you're getting 46-47 kW, that's ok. Your graph above showed less than 45 kW, so that was the concern.<br /><br />But it is concerning that Bolt with 3X bigger battery than SparkEV cannot charge at same power level to 80%, which SparkEV can. With such big battery, I had expected Bolt to keep close to 50 kW way beyond 90%. I hope this is something they can improve upon with service updates.sparkevhttps://www.blogger.com/profile/04362518920979349841noreply@blogger.comtag:blogger.com,1999:blog-4272464600969867708.post-65795060709528636892017-01-14T10:12:58.435-08:002017-01-14T10:12:58.435-08:00I have tried several chargers around my area and n...I have tried several chargers around my area and nothing will go above 46-47kW and the taper points seem pretty consistent as well. Seems like the best zone to charge in is 0-55%. Anything above that and you start to see much longer charge times.

Could it be that the charger was faulty? Can you try it again at different charger? Maybe not sit there for full 90 minutes but maybe spot checks to see how different it is?<br /><br />SparkEV shows constant 48kW in many chargers, but there are few that show less, anywhere from 36kW to 47kW. If you have or know someone who has SparkEV, you might ask them to plug-in first to see how the DCFC performs before starting your session.sparkevhttps://www.blogger.com/profile/04362518920979349841noreply@blogger.comtag:blogger.com,1999:blog-4272464600969867708.post-73248205791369613532017-01-13T16:34:24.790-08:002017-01-13T16:34:24.790-08:00I am charging now in one session and just passed 5...I am charging now in one session and just passed 55% and the same behavior I noticed before, dropping from 45kW to 37kW, is happening. So there is a hard taper starting at that charge level.

Might have to wait for Bakers in June. <br /><br />It would be interesting to see a charge speed graph from an FC that doesn’t terminate the session. Im hoping a continous charge will allow 40kW+ way over 50%. Falling below 40kW at 50% is disappointing for at 60kWh battery.<br />Anonymoushttps://www.blogger.com/profile/01805585154822218248noreply@blogger.comtag:blogger.com,1999:blog-4272464600969867708.post-23318149433367759552017-01-12T11:41:26.313-08:002017-01-12T11:41:26.313-08:00As far as I know there are no chargers over 50kW r...As far as I know there are no chargers over 50kW right now in the USA.Jackhttps://www.blogger.com/profile/07987108079809048131noreply@blogger.comtag:blogger.com,1999:blog-4272464600969867708.post-44722769513446122312017-01-12T09:46:15.111-08:002017-01-12T09:46:15.111-08:00This comment has been removed by the author.Anonymoushttps://www.blogger.com/profile/01805585154822218248noreply@blogger.comtag:blogger.com,1999:blog-4272464600969867708.post-5154826870775525932017-01-12T08:57:02.208-08:002017-01-12T08:57:02.208-08:00Great report, thanks!

It might actually mean that Bolt is able to charge at full power(perhaps 80kW?) up to 50% SOC.<br />0-50%-> 80kW<br />50-70%->36(?) kW<br />70-80%->24 kW<br />going from 5 to 80% SOC in ~55minutes. A roadside picnic? More like lunch. Also charging beyond 80% becomes a bit pointless.Anonymoushttps://www.blogger.com/profile/10370868065444278488noreply@blogger.com
