2018 Leaf Quick Charge

Mon Mar 19, 2018 12:30 pm

Hi everyone, I have a 2018 SL that I’ve been quick charging from time to time from about 30% or so and I haven’t seen 50 kW on my dash. The most I have seen is 27kW. I’m not having good feelings that this car on a long trip is going to charge fully in 30 mins or even an hour. When I do charge I get 80A 400V but inside I’m reading 27kW.

Thoughts?

Can you post some Plugshare locations of where you're DC charging at?

Some don't have high max wattages and some of them will not charge at full power if some modules in the DC FC fail.

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

It's not realistic to expect a full charge in half an hour, or even an hour if the battery is low. The charge tapers, so even at a full 50kw you will get less than that in an hour. QC stops are best for getting up to 80% charge.

@simply Based on your profile, you haven't owned a LEAF before, nor perhaps any EV.

Based on that assumption, there's a bit of a learning curve to the charging strategy for longer trips.

Like @LeftieBiker said, charging to 100% takes too long...

Typically, as long as there is opportunity along the route you choose, you want to charge to 100% before you leave, then drive until the SOC is around 20% and charge up to 80% at each DCQC. Repeat that cycle every 100 miles or so (2018 LEAF), until you reach your destination. Overall, using that approach minimizes your total charging time for the trip.

It's becoming clear from new UK Leaf 2 owners that there is a major problem with the 40kWh battery overheating on long trips. After 1 or two quick charges the car throttles the charge rate back to 22kW regardless of SOC.

What this means is that the new Leaf is 3 hours slower over 400 miles than the outgoing 30kWh model. Bear in mind it's still not far above freezing in the UK so this will be far worse in warm parts of the USA during summer.

I seem to recall the man in the video above saying specifically that the battery was NOT getting hot - that the reduced charge rate had no obvious cause other than the car deciding to throttle it back.

Sounds like slow charger to me. They come in all speeds. EVGO used to all be 100 amps (some were even lower) but most have been upgraded but strangely not all run the same speed. Some at110, 120, 121, 124, 130.... weird...
