Re: using a Lev50 pack for solar

It will enable the Low Voltage power supply +5V created from the cells; the CAN commands will need to be sent to control the balancers.

i think tomdb on the DIY electric car forum has decoded the balancer commands and even makes a SIMP BMS board to control all the CMU boards.

Re: Cost to replace an i-miev battery?

That is a very quick and simple spot welder. Was there any sort of resistor underneath the clear RTV and black tape, and what was the purpose of the 2 tiny wires on the supercap? Here's a couple of spot welder links also: https://www.sunkko.net/sunkko-709ad-pulse-battery-spot-welder.html and a diy A...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

i had a really hard time trying to cut thru the black epoxy, but if you could remove it then it should be possible to replace the diode(s). Did you happen to see the picture on page 6 http://myimiev.com/forum/viewtopic.php?f=23&t=4079&start=50#p36810 it shows the layout of the diodes. That s...

Re: using a Lev50 pack for solar

i was thinking that i had posted the schematic for the CMU board, and as i recall there is a low voltage power supply on the board that is generated from the cells. [edit] found it here, it appears to need an enable thru the 12V aux from the EV-ECU. http://myimiev.com/forum/viewtopic.php?f=23&t=...

Re: No READY. P1A15 error. Condenser charge timeout.

That's some good troubleshooting, especially adding the heater. i would guess that there is a ceramic capacitor (C227, C229, C231) that is leaking as the temperature goes up. i chased something like this in a Volvo fuel injection computer years ago. Maybe you can repeat this and then use a can of co...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

i know it's long, but how much of this thread have you been able to read? The first 2 posts have an index and links to other failures, there is also some schematics links. On page 45 is a schematic with the diode voltages that you can use to check if the high power semiconductors are shorted or open...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Hello. I have the same problem I've seen in this forum. The car has stopped charging. As I unscrewed it, I noticed that the R106 resistor is damaged. This is a resistor to limit the charging current of three 680 uF capacitors. After replacement for a working one, nothing has changed. After connecti...

Re: Troubleshooting and repair for On-board Charger (OBC), DC-DC Converter

Hi Guys, few weeks ago I recived another charger with blowed up blue capacitors. Replaced them and send back charger. Now I get it back again. It's not charging. For the firs time I saw that one of the three capcitor is a little bigger. Voltage on PFC is 316,9V I'm using true rms multimeter. Is it ...

Re: The Magnet Hack?

Do you have a model or part number for that device? Maybe we can find a datasheet or info on the magnet feature.
