Hi forum! I recently embarked on a journey to increase the performance of my LEAF. I've made a video series on this subject, might be interesting for many here
All Leaf packs are nominally 360 volts. A higher-power inverter doesn't need a larger battery, but to take advantage of the capability of the inverter the battery must be able to withstand the discharge rate; Nissan only uses an inverter allowed to run this much power with the 62 kWh battery. With the 40 kWh battery power is limited to 110 kW, and with the lower-capacity batteries the limit was 80 kW. DIY builders often exceed the factory power limits.So what battery size do you need with this size of inverter?
The problem with "peak current limit" is that it depends massively on the time - for continuous - as in minutes - 3C is probably max - and that will empty your battery in 20 minutesDoes anyone know the peak current limit for these first generation (24kwh and 30kwh) Nissan Leaf batteries? Would it be possible to power a 220kw Tesla small drive unit with these batteries? I'm guessing not, but I am struggling to find peak current numbers for these battery packs. Thank you!
Thanks, and YES! One of the first things I did was to message all my findings to Isak, and he now has confirmed the 110kW inverter to work perfectly with the Resolve controller. 160kW has identical commands, so both will work!Dala you are a pioneer doing great work! With this procedure a 110 or 160kw inverter can be used with a Resolve-EV as well, correct? You make it so easy to just....oh you know...DOUBLE THE POWER!
Hi Dala! Thank you so much for sharing this info. About how much should I expect to pay for one of the 160KW inverters. Do you have a special source or is it 'salvage yards' around the world?Here's a list of inverters for ZE1 incase you are buying one:
ZE1 inverters (2018-2022)
291A0-5SA1A - 110kW inverter
291A0-5SA1B - 110kW inverter
291A0-5SA0A - 110kW inverter
291A0-5SN0A - 160kW inverter
291A0-5SN1A - 160kW inverter
Salvage yards for the win! Nissan quotes >3k for an inverter, but depending on the salvage yard these can be had for between 500-1300USD depending on the place.Hi Dala!

@Dala - Hi Dala, I'm curious what you think the limit of the Nissan Leaf batteries are and if there is chance they could power a 220kw Tesla small drive unit for short periods of time, 5 to 10 seconds?The problem with "peak current limit" is that it depends massively on the time - for continuous - as in minutes - 3C is probably max - and that will empty your battery in 20 minutes
For a few seconds down the straight before braking for the bend?? - I'm drawing 28C from Chevy volt modules
I suspect a Leaf would NOT be able to match that
But 10C for five seconds should be OK
