Re: And now my I will not charge!!

i posted the schematic in the troubleshooting thread.

The two big 4.7 Ohm ceramic resistors are connected in series and provide a bypass path across the relay contacts. These are made by Tamura, the larger one with green ink (TAM P10K series) is a thin-film current-limiting fuse, and the smaller one with blue ink (TAM 5K series) is a wire-wound cement-filled ceramic-housed resistor.

i checked the www and Tamura seems to have sold off their resistor business, or doesn't list these parts in their products list.

P10K series, green ink
- Thermal-Links/Resistor Assembly is a product which is made of pellet type thermal-links and 10W type resistor.
- P10K is RoHS compliance product, non-Pb and non-Cd contains.
- P10K got excellent interception characteristic when abnormality overload happened.
- Especially, P10K adopted excellent characteristic resistive element against the In-rush current, and it is the best for preventing In-rush current.


5K series, blue ink
- Cement resistor is a product that combined with 5W wire wound resistor (ceramics insulator) type.
- 5K is RoHS compliance product, non-Pb and non-Cd contains.
- Especially, 5K adopted excellent characteristic resistive element against the In-rush current, and it is the best for preventing In-rush current.

Hi Kiev,

Thanks for that. I'm going to wait for the results of your investigation into the working of the charger and see what my options are. I haven't pickup up my unit yet, but when I do I'll post some pics of that it looks like. For the moment I'm going to work on hypermiling a 2005 Honda Odyssey. Got it down to 8.2L/100km so far. I've realized that I've developed an "Empty Tank Anxiety"! Just dreading another fillup, gas is pricey here (for NA anyway).

My battery is degraded, I'm down to 34 ah and when my charger failed and I was hopping between fast chargers I drained the battery down to creep mode and canion said it was at 7.5% SOC so I'm not sure if spending several thousand dollars on a charger will be worth it if I my battery warranty runs out and the range is limited.

Keep up the great work. I really appreciate it.

I picked up my charger yesterday. I want to share the images of the damage.

Here are the cracked resistors

Here is the bottom of the board they came out of with damaged areas circled

This is where all those pins were desoldered to release the board

I’ve purchases a charger from a 2013, I’m going to need some advice on installing it, I will post that in my other thread

Were those circled diodes damaged?

Was the white solder pad strip already scorched, or did that happen during the de-soldering?

He circled the diodes because the area was darkened and he assumed they were damaged.

And here’s s comparison of the solder pad strips. His only comment on those was how much work it was removing the board.
