Hi - I'm very interested in your project. I purchased my 2013 model S a week ago and I have an OpenEVSE on the way as well as a Pi and a Bluetooth OBD-II adapter I was planning to use for a similar project. Do you have a website or other post that has more details on what you've done so far?bearer wrote:I just started wrapping my solution to this up. I put an Arduino Nano uC* with a nrf24L01+ radio inside my OpenEVSE, and connecting the serial port to the OpenEVSE.lpickup wrote:One idea I had is based on the OpenEVSE charging station, which by its open source nature is modifiable by someone with the necessary expertise. If you do not have such expertise, maybe you could ask the OpenEVSE community about adding this feature.paulhome wrote:Would it be feasible to enhance leaf spy to stop the charging process at a certain charge level?
I would be prepared to pay for this feature.
Then I have another uC in the car that is connected to the EV bus, it picks up the SOC data and transmit it to the uC in the OpenEVSE. The uC in the OpenEVSE also receives temperature from the plugs and a Target SOC from the car among other thins, and issues the needed serial RAPI command to OpenEVSE to stop charging when target is reached or reduce current draw if its a worn down outlet what is getting to hot to pull 3.6kW from.
I'm not sure how feasible it is to add the functionality directly to OpenEVSE as the current code pretty much uses nearly all available flash.
I would love to be able to send a CAN command to stop the charge instead, as currently it will not work with public Type2 chargers that is becoming the new standard here. (Not without using a Type2 to IEC outlet and then to my OpenEVSE)
*) board does not like greek micro symbol?!
Most likely the draw of the KW902 pulled your 12v battery down lower than it wanted to be and you got the Christmas tree dash lights. Change your lead-acid 12v battery. Make sure not to leave the KW902 plugged in unattended. You can probably use the KW902 without replacing your lead-acid battery but make sure you have the car fully powered on and ready to drive first.Leafpack wrote:I purchased the Konnwei KW902 as recommended by Leaf Spy, After plugging it in my 2012 Leaf went haywire and the display in the leaf showed multiple errors. I could not even power off the leaf. After unplugging I was able to turn the leaf off and it still showed multiple errors but was now able to power off the leaf. Has anyone else experienced this issue? After multiple power cycles to the Leaf, I have now gotten rid of the errors.
Why would this device cause such issues? Is this a fake device or does my leaf have other issues?
Any help would be appreciated.
Yes, there is a manual in the app itself.Zapped wrote:is there an up-to-date FAQ or user manual somewhere?
I think the cell-pair numbering matches the module locations shown in the service manual. Example: Cell pairs 1and 2 would be in module 1; cell pairs 3 and 4 would be in module 2; ... and cell pairs 95 and 96 would be in module 48.ctrama wrote:Hello,
I have been using a KONNWEI OBDING tool. I scanned a Nissan Leaf and I could get the information to an excel sheet.
I was able to figure out the voltages of the 96 paired cells.
I need to know how can we physically identify the particular paired cell and battery pack 1,2 & 3?
For Example: How can we find out the exact location of the CP10? In which battery pack is it located?
