Hopefully this video when viewed in conjunction with the others in this thread and the accompanying notes
will be detailed enough for people to charge or cycle their own CRZ Nimh packs.
Basic requirements.
1) Rubber gloves. (To be worn at all times.)
2) Tools inc trim clip remover.
3) Dry & cool working environment with access to mains power.
4) E-Bay
constant current LED Drivers with combined 130-140V output at a ~200-300ma
5) 12V 0.5A minimum cooling fan or equivalent for mounting on IMA air vent.
5) 60W 120V minimum incandescent bulb mounted on a secure insulated support. (Bulb only required for discharging)
6) Insulated miniature crocodile clips and wire.
7) Time and care.
Process. (Simple Charging)
1) Remove sufficient trim and carpet to gain access to IMA battery.
2) Turn main switch off.
3) Remove IMA battery metal cover.
4) Mount 12V cooling Fan to IMA exhaust vent and block off the rest of the grille.
5) Attach grid charger to IMA battery.
6) Turn on main IMA switch.
7) Turn on mains power.
8) Leave to charge for 24hrs ensuring cooling fan is running at
all times.
9) Turn off mains power.
10) Turn off main IIMA switch.
11) Disconnect charger
12) Reassemble IMA and turn on main switch.
13) Reset IMA system by disconnecting 12V battery lead under bonnet for about 20 seconds.
Note. If you have an HDS or OBDIIC&C you can set the SOC to 75% (High) using that instead of disconnecting the 12v battery.
You should also reset the usable battery capacity to the maximum using the HDS or OBDIIC&C to restore lost capacity.
14) Start car and allow to idle for a few minutes, then drive as normally.
If you battery has not recovered or still performs poorly then you can try cycling using the discharging process below.
Process. (Simple Discharging using the bulb)
1) Charge frist for 24hrs (See above, unless you have just already done that.)
2) Turn IMA switch off and disconnect charger.
3) Attach 60w bulb.
4) Turn IMA switch on bulb should light up!
5) Leave until it goes out. (The longer it takes to go out the better)
6) Turn IMA switch off, disconnect bulb and leave for 1hr.
7) Do charge process as previously described for 24-30hrs.
If the IMA battery does not recover after cycling as above then it requires much closer inspection and may be beyond help.
Good luck.
