Non OEM Leaf battery upgrade?

Hi All, These look to be a generic brand Samsung SDI cell, and could be a winning formula for cost effective, high energy density storage. http://www.liyuanbattery.com.cn/en/product_detail-788672-1943470-81261.html Their 135 Ah cell promises 220 Wh/kg - about twice that of the original Leaf battery ...

Re: dogphlap's Jumbuck

I have this exact motor and inverter ready to go in the Prelude. Did you ever install it? Did you find the gearbox was essential? Need the clutch?

Nissan battery packs are very easy to retro-fit with new battery cells. Sounds like a project.

Re: Off-grid solar diagram / ideas

If I'm not mistaken, the way this is set up, should the BMS decide to cut the contactor off it will remain off even when the sun comes out again. If the BMS is the last line of defence this might be fine. I think the PIP5048 can be set to stop drawing power at a setpoint voltage, like 43 volts or so...

I've decided to start three threads on how the keen amongst us might set up a solar + storage system. Pending further input from the brainstrust here, this would be a fairly sensible way to do it: An off-grid setup: offgrid setup.png The PV array is set up as three panels in series, and as many of t...

The three phase adapter only allows you to access single phase to supply the on board charger. It won't charge any faster, it just gives you more options.

You will definitely need the gearbox - anything under 200 Nm is a bit weak for pushing 1000 kg of car around.

My 4 kW scooter does 70 km/h, and that's honkin' on bobo. So 8 kW should manage 100 km/h (eventually).

I have noticed the heat pump running after I have turned the car off after a long drive.

I suspect the car uses the heat pump to hold the battery at 20 deg C or so all the time. Or at least while driving, charging and immediately after both
That's a very good thing - heat soak is a killer.

Hi Martin, The motor on the swingarm is a well travelled route. If you can make it fit I think it will work quite well. The battery though - a little bulky for the energy stored, but the right price I guess. At least with the motor out of the way you should be able to fit them. Otherwise you could g...

DC motors are not very efficient - most are around 80-85%, while AC motors are...
