If the keys are buried in a bag I find it 's easier to bring the bag to the car and open the door and press the button to open the charge port rather than find the keys and press the button on the key. OTOH, inside release fuel filler doors make sense. They help prevent fuel theft. But with an EV, who's gonna steal your electrons? Agreed, there isn't a major need to lock the charge port, except perhaps to reduce the vandalism attack surface. Other cars do it better than the Leaf, for example the i3 charge port opens when you push it, but it still locks with the car which may or may not be necessary. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)

Re: [EVDL] Leaf battery pack overheating due to depth of discharge.
Lawrence, Is this a 30kWh leaf? We've seen that they will accept charge much faster than the 24kWh leaves, maintaining 50kW for most of the charge to 80%. This will put a lot more I^2R heating into the battery than charging slower. The 24kWh cars average under 25kW for a charge to 80%. How hot is 5 and 9 bars?

[EVDL] Nissan Leaf CAN Bus Man in the Middle
I wrote a man in the middle for the leaf battery communication. It uses can4python and Kayak's kcd format to describe the signals. It probably only works on Linux. Source code is here https://carrott.org/git/leaf-can-utils.git It decodes all the messages received on one interface (from the battery) into signals, lets me change their values, and then re-encodes them back into the can bus format, recalculates the new checksum when necessary and sends them out the other interface (to the car). Yesterday I spent some time testing it on a Gen 1 leaf at https://bluecars.nz We cut the can bus wires inside the battery box, just after they go through the water proof connector to the outside and connected about 1 metre of thin figure 8 wire to each side of the cut. This let us access the bus on the car and the bus on the battery while the battery was plugged in under the car. It's possible to get enough slack in the internal battery loom to feed the connector all the way through the machined hole and make room for some extra wires to pass through. With the two pairs connected together, the car behaved normally, going into ready and spinning the wheels. The BMS module terminates the bus so we connected a termination resistor to the car side of the cut and used termination on the CAN interface talking to the battery. We plugged the other end of the man in the middle to the OBD2 port and didn't use termination. The MitM just worked. The car is very tolerant of errors on the CAN bus. You can stop the battery messages and it goes into turtle mode and all the battery info disappears off the instrument cluster. When you re-start the battery messages it goes back to normal mode and the battery info reappears. Start-up is quite critical, if you don't let the battery send it's start up messages the car doesn't go into ready mode. The car never shut down or went into a permanent turtle mode while I was messing with data on the bus -- it always went back to normal mode if I restored the unmodified messages flow from the BMS. I modified the data in nearly every field to see what would happen. The car will go into ready and turn the wheels even when it cannot send messages to the battery. This means the startup sequence doesn't involve a car to battery handshake, even if the car is expecting some startup messages from the battery within a time window. The "check engine" light comes on and it does record some DTCs: * P3180 (EVC-249) VCM detects an error signal that is received from LBC via CAN communication for 0.02 seconds or more. * P3183 (EVC-250) After a lapse of 0.3 seconds from M/C RELAY ON, the following state remains for 2.8 seconds or more: LBC's calculation result to the VCM-set example question is incorrect. My MitM only works in one direction (from the battery to the car) and it turns out my CAN bus setup wouldn't let two programs play together, so when I started a CAN repeater (candump -b) to copy data from the car to the battery I got corrupted frames and no buffer space errors. I'm going to make the MitM work in both directions to resolve this. If you play a different car's battery messages into this car, it does not go into ready. I didn't spend much time on this and I didn't write code to start the BMS messages at the right time, I just started playing the recording of a running BMS and switched the car on. One experiment that I should have tried was to start the car with it's real battery and then switch to messages recorded from a different car. There are some new DTCs when you try to start a the car while playing messages recorded from another car including * P3102 Li-ion Battery ID Registration must be performed if the Li-ion battery controller or VCM is replaced. The next experiment is to swap in a BMS module from another car. I figured out some more of the BMS protocol by messing with the data and seeing how the car reacted. The Fuel Gauge display on the instrument cluster is powered by the GIDs signal (the first 10 bits of 0x5BC), not the state of charge signal (first 10 bits of 0x55B). I guess it knows how many GIDS is "full" because the battery will have fewer gids and still read full as it ages. 0x5BC bits 36-39 (ie the high nibble of the 5th byte) somehow effects the Fuel Gauge, lower numbers mean more bars, all other things being the same. Maybe this is used to calculate how many GIDs each bar is worth? I haven't explored this. The battery capacity gauge (the bars outside the fuel gauge) is controlled by a muxed field, when 0x5BC bits 32-35 (ie the low nibble of the 5th byte) is 0x3, 0x5BC bits 16-19 (ie the low nibble of the 3rd byte) contains the capacity bars. I haven't yet used the mux field support in the kcd format to express this -- can4python doesn't support it so I had to hand code it. The cluster does not remember the capacity -- changing this value directly manipulates the number of bars displayed, the

Byte 4 (the fifth byte if you start counting at 0) is always a constant value for a given car. It stays the same across all 0x5C0 frames, it stays the same whether driving or charging. Every vehicle I've got a capture from has a unique byte here that never changes with any captures from that car no matter what else the car is doing. Pretty much all of the rest of the bytes change as you charge or discharge. I think what might be happening is that this byte is a sort of identifier that the rest of the system uses to see whether the pack is the same one it last knew. 256 unique values might not seem like a lot but that means that your odds of getting a pack with the same byte as your old pack is 1/256 or less than 0.5% - not so likely. One way to test this would be to set up a man in the middle configuration and then change that byte and see if it makes the car puke. Or, take a car with a replaced pack and try to change the reported byte from the new LBC to the reported byte from the old LBC and see if the car then wants to work better.

Japan has different voltage and frequency to the supply here, leaf charging cable: 200V 60hz, NZ voltage 230V 50Hz. There is a small transformer in the cable that has to be changed, but opening the cable means that it has to be re-certified. Does anyone know what the charging cable electronics does? The cable has an EVSE embedded in it. This basically tells the car how much current is available and only turns on the power if a car is actually present. In the EVSE supplied with the Gen 1 cars the power supply for the circuit inside the EVSE has a mains step down transformer not for more than 200v. This transformer will saturate on 240V and get very hot. The dealer forgot to do the replacement on our car and it failed after about 6 weeks being plugged in continuously. They replaced it with one that had been modified. I think you may also have to replace some over-voltage protection too. What is the certification you're worried by? I'm not aware of needing a certification to plug something in in New Zealand. The EVSE supplied with the Gen 2 cars is smaller, I don't know if that one needs modification or not. If you don't want to modify the Nissan EVSE you might look at https://bluecars.nz/bc-shop/ in Auckland. Carl has an 8-10-16A selectable EVSE with a 16A caravan plug & a caravan to "normal" 10A 3 pin plug adapter (with 10A circuit breaker and RCD). He also has a fixed 8A EVSE. ___ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Read EVAngel's EV News at http://evdl.org/evln/ Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
