Hi I’m currently plugged into a BP pulse 175kw charger in the kona car is at 8% but car only drawing 40kw is this normal as never used a rapid charger before only a 50kw
You need to have a warm battery to get the highest speeds where you should manage 75kW or so.
Is it a fairly local charger? Unless you have done a long distance motorway drive before plugging in your battery will be nowhere near warm enough.
Cold battery… it will improve, a bit, eventually, and if you are lucky you might see 70+ just before it then slows back down again at 56%
Even then, it often won’t be warm enough on the first charge of the day as driving doesn’t add much heat to the battery, in the Kona at least.
It was a 10 mile drive to get here it’s now at 53kw so a bit better
Fair point. All the times I have had a Kona it’s been summertime so my starting battery temperatures would always be higher.
Took an hour to do 8% to 80%
I have found that BP chargers seem to take longer to charge my Zoe than others.
Regularly use a charger at a tube station up the road, leave it for an hour while I take the dog for a walk and it will get to 99% to 100%. The car park was closed for a couple of weeks went to the BP 175Kw ones 15 minutes away and after an hour was only at 90%. Temperature and conditions similar and tried this 3 times with similar results. Therefore, avoid these if I can.
Only way to know for sure is by working out the average speed of each charger. How many kWhs did they each deliver during that hours charging?
I found my ZE50 says it is charging faster than it should on a 7kW post, but then the last 2% takes ages while it balances the cells. All in if I charge from almost empty to full, it averages about 6.9kW/hour.
The ZE50 on CCS will max out at about 45kW on any rapid charger, and that’s only from 10% to 50%, after that it drops to around 30kW. I’ve had these same speeds from three different Rapid units, including a BP.
I did a test at an empty charger and found on 50kW CCS that charging past 90% drew about 17kW, and on 22kW AC it drew around 15kW. This wasn’t on a BP unit. I don’t bother Rapid charging past 80% as it’s just super slow and not worth the extra wait time.
With the Zoe’s range you don’t really need to go above 80% unless you’re about to do a really long journey. Balancing only needs to be done occasionally so you can do that at your convenience when you are not in a rush or have something to do while waiting.
I tend to leave mine when it hits 10%-ish during the day while I’m working so it just happens to charge fully anyway.
Rapid Charging past 80% isn’t worth it for me, as you say the range is great and rather than sitting watching the last 20% slowly go in, I’d rather just leave with 80% and spend a few minutes charging 90/120 minutes down the road - if I need to.
