Re: Increase charging rate.

From my experience with paralleling a 12 KW charger to the battery pack, you might be able to add the additional input into the pack without a problem. In my case, if the car was connected to the EVSE and charging normally I could apply additional input to the pack up to a point. I don't remember ex...

Re: Sales Statistics

Wow! How come I didn't get tire "cozy's" with my car! On a serious note, I can't figure out why they are covering the tires. It's possible that the cars were going to be (or are being displayed) in some area where the tire rubber contacting the service might have left marks or damaged the ...

Re: AC compressor NOT starting. Relay is not kicking in.

One final thing and then I will sit back and relax. The oil used in the A/C system is different than oils used in other common automotive systems. This is because of the dielectric properties required to ensure the motor winding insulation isn't damaged by the oil. I remember reading about this in t...

Re: AC compressor starting. Relay is not kicking in.

Yes, there are more fuses. However they are in the battery pack and are connected to the high voltage DC supply. There is one for the A/C compressor and one for the PTZ heater in a compartment accessed through covers on the bottom of the pack. I think it is time to go to the dealer to have him diagn...

Re: 12 volt battery charging

Remove the 12 volt battery and have it load tested at a battery dealer. If it's OK, charge it up and let it sit for a day and check the terminal voltage. It should stabilize about 12.5 volts if all cells are in good shape. If you have any question about the battery, replace it again. Buy the best ba...

Re: New I-MiEV's --- Maybe, maybe not

Bi-directional inverters can usually flow the same amount of power in either direction. If you have an inverter that can convert DC to AC to drive a 200 KW motor then, instead of connecting the output to the motor, it can be connected to a three phase source, changing the direction of power flow and...

Re: New I-MiEV's --- Maybe, maybe not

The Zoe has a kind of unique internal charger. The I-MiEV and most EV's have a inverter to convert DC to three Phase AC to drive the propulsion motor. They also have a battery charger to convert single phase AC to DC to charge the battery pack. However, an inverter can be made to be bi-directional, ...

Re: Maintenance of gearbox ....

Pretty sure there is no requirement for any EP (extreme pressure) lube like rear axle oil. I always ran the lowest viscosity oil I could find, like a 0W20 synthetic engine oil. I finally found some quarts of GM EV-1 transaxle oil which has a viscosity about the same as water. Worked just fine--still...

Re: Annual Fees to Compensate for Gas Taxes in Some States

Florida hasn't had a tax on electrics yet. However, they did have a sticker you had to buy for CNG powered vehicles. $150.00 per year per vehicle. Problem was (and this will impact electrics if enacted) it was necessary to use a "refueling station". At the time, there were only a couple of...

Re: Who has felt a rumble in the rear?

A "rumble" sound seems more like it would be tire noise or a wheel bearing. However, application of power or regeneration might change it a little but even when coasting at the speed you hear it under load or acceleration it would still be there when coasting. If the CV joint boots look in...
