Re: my Miev will not charge

Tue Oct 24, 2017 8:15 am

i've had this happen several times, and found dirt and debris on the pins in the charge port. i cleaned it with alcohol and a cotton swab (there is no high voltage on the port pins), and it is fixed until the next time it happens--rinse and repeat... also cleaned out the socket terminals of the evse handle too. My car and evse is outside all the time.

I brought it to a dealer and they said it is the on-board charger. The on-board charger stopped communicating with the rest of the car. It is over 5k to fix. The car is only worth 4.5k. Sadly I have said good bye to the Miev.

@Sbess, where abouts are you located?

Piev and i reverse engineered the TCCH/ Elcon chargers and have performed numerous modifications (# of cells, voltage levels) and repairs including replacing the microcontroller chip and loading new firmware.

Maybe we can fix it, got to start somewhere.

Software and Hardware Bugs

Sun Oct 29, 2017 6:04 pm

Turns out i had more than just the usual dirt and debris because it wouldn't charge again, so time to investigate. i have a Blink WE-30 level 2 EVSE unit that is mounted outside under a shade tree.

First obstacle is the security screws on the EVSE handle, and they are not 6 pt torx either, they are called Torx Plus Security screws with 5 splines and a center pin. These are called size TPS15. $25 bucks for a set of bits if you can find them. They were repaced with regular #6 x 1/2" wood screws philips head

Then i found bugs in the hardware--alabama fire ants crawled thru the 3 little vent/drain holes in the handle and made a nest.

Not much stuff in the handle, just a pocket full of shells. Not surprised to find this handle was made in Germany--silver label under the circuit board, the mains line wiring colors, and the use of those stupid TPS screws were the clues:

Gave it a good cleaning, and now it's charging again. So check for bugs, they are not always just in software...

I have been slowly stripping a local low mileage crashed I-MiEV, could see how much they'll take for the charger if you like.

Kiev, thx for the "TPS Report", and burning memories of debugging. Fire ants are one thing I do not miss about the South!
