Just an impression: When I use Instavolt or Polar rapid chargers it seems that my battery temperature indicator collects an extra bar compared to a similar charge on an EH charger. Anyone else notice this?
Below 50% your battery voltage will only be about 360V, which at the max current of 125A is 45kW. I tried when my battery was warm, meaning it was willing to go full pelt up to about 90%. At that point the voltage was close to 400V, giving the 49kW.
Instavolt chargers max out at 125A. DBT chargers max out on Chademo at 106A.
The new chargers do deliver power faster, yes, which does result in temperature increasing faster.
The big thing that forces temperature up though is running the battery right down to a low SOC and then rapid charging up to a high SOC.
The best approach to avoiding excessive heat build up in a long journey, that I have found, is to keep the battery between 25-80% and stop more frequently. The tricky thing is that with the newer chargers being faster, it’s much harder to judge getting back to the car in time to do so!
I have a rolec 32amp charger, but my new I3 will only charge at a maximum of 16amps.
There is a seperate thread on this in the i3 area of this site.
The question I have is with the Rolec charger.
I tried changing the charge setting resistor to a different value via a variable resistor. It seems...
It is received wisdom that frequent rapid charges and staying at 100% reduces battery life and that rapid charging over 80% is time wasting.
But I have never seen any advice on frequent low rate charging (1.4-7.5 kW) or even keeping the battery at a higher level, say 80% to 95%, having any...
As you all know, it has been a bit wet recent. I was at the Clacketts lane service station yesterday and noticed that nobody had bothered to replace the plugs on the three Ecotricity chargers and they were all sitting around on wet ground or in puddles.
I had no need to charge but wondered if...
I took some close up photos of the internals of my Pod Point charger today as I was wondering what type of MCU was used with a potential idea of writing some custom software to implement hooking in for charge timing etc. (Not going to happen now).
Thought some people here might like them. The...
