Limiting charge power from within the LEAF!

Dala · Aug 31, 2020

So this is a feature that I think should have been mandatory on the Leaf, since it increases safety tremendously. I was so upset that this feature wasn't there, so I added it myself.

Here is a link to the software for anyone wanting to try it at home: https://github.com/dalathegreat/Nissan-Leaf-ChargeCurrent

Great feature. Can we bring power draw down to 1 amp?

Power draw can be lowered to 500W and still charge the car. The car itself draws roughly 300W, so only 200W will then go into the battery. This is ideal for those solar builds, but keep in mind that efficiency will be low at these extremely low power levels!

Great. All the cool toys come out after I sell my leaf. sigh.

My rockpals 500watthour pack and solar panels look like a viable option again.

The car overhead is a consideration though. To your point, we would need 500w of continious power to make it minimally worth it, and add a gentle mile per hour.

I've expanded this functionality to also work with quickchargers. Take a look here if this sounds interesting to you, also cover rapidgate/degradation/cooling

This is not revelant to this topic, but
To stop charge in 0x1DB
frame.data[1] = (frame.data[1] & 0xE0) | 2; //stop
frame.data[3] = (frame.data[3] & 0xEF) | 0x10; //say full
