What about a faster charge option? Maybe after this Nimh rebalance process.
If I understood the IMA motor can send up to 75A, 100v energy to the battery, using the inverter.
I will can
flex the CR-Z to the ZEV charging station, using a formerly owned Type 2 to Schuko adapter
This is an interesting and perfectly logical question.
Yes the car can recharge at fairly high power levels for short periods when running.
But getting the car (standard Nimh IMA battery) to accept power from a high power external source is extremely difficult to do safely and of very limited practical value.
1) The standard IMA battery contains a tiny amount of
useable energy < less than 600wh. (A 60kw (60,000wh) charger could charge it from 20-80% Soc in <10 seconds!)
2) The car will not accept power from an external source when on without throwing multiple error codes unless you do some very clever/difficult electronic fooling.
3) Force charging the battery at very high power levels when the car is off would require accurate additional (expensive) cell voltage, temperature monitoring and fan control.
4) Fooling a high power public charge point into actually turning on and delivering controllable power at the right voltage/current to a non OEM setup would not be trivial.
5) After charging you would need to use an OBDIIC&C to set the car SOC to high 75% or the car would simply think the SOC was still at it's previous level.
6) You also need to arrive at the charger down at 20% Soc, but the car won't let you do that without more hacks.
Of course it's an interesting project idea and even more tricky with an inflammable Lithium car
In practical terms though, the amount of energy you would gain, let's say ~0.5kwh (10 cents) is simply not worth the time/effort/expense to implement.
Unless of course you have the skills, are in lockdown, stuck at home and you like tinkering.
Using a home 1-7kw option could be possible but again the $$$ return on investment and technical difficulty is very much negative!
In the UK a 3kw domestic charger could do 20-80% Soc (Roughly 4Ah) in about 10 minutes.
