Uh-Oh Battery Cell Troubles

Well, the i-MiEV had to take an unexpected trip to the repair shop due to a battery malfunction a little while back.

To date, we’ve been unable to extract the cause of  the problem. All we know is that the battery had a bad cell and needed to be replaced.

Thankfully, the i-MiEV is under warranty, as a new battery is very, very expensive: approximately $17,000!

The i-MiEV all loaded up and ready to go get the battery replaced.

Here’s the symptoms we encountered when the bad cell presented itself:

“The vehicle was not letting the battery take a full charge.  We noticed after charging over night the meter indicating the battery state of charge was not full up,” says ROKO Ltd. owner Harald Kober.

When plugging in the i-MiEV, the charge function would stop — sometimes immediately and sometimes up to half an hour later.

“Furthermore, after driving the vehicle without a full charge an indicator light came on in the dash which suggested a problem.”

So we transported it to Mitsubishi, keeping in mind that the i-MiEV can not be towed in a conventional fashion. It needs to be transported on a flat-bed truck.

Since it’s return to our care, everything has been running smooth — we’re now putting it through some cold weather exercises to see how it copes with Okanagan winters.

The day the Queen visited Roko

Here at Roko Service Ltd., we were reminiscing over a cup of coffee and remembering back to a time when Queen Elizabeth II and her motorcade stopped by to visit shop founder Roland Kober during their royal tour in 1959.
