Green lightning bolt while fast charging

[Max Powers]

So this has happened to me a couple times, and I can't find any details about what it means.
While sitting at an EA 150kW charger, I've noticed the charging speed ramping up above the charger's rating and seeing the charging lightning bolt turn green.
I suspect it's the onboard charger kicking on but I read that it only works with 400V chargers and EA uses 800V so it doesn't really make sense.
Has anyone else seen this?

ive seen this as well and think it is when the system is realllly sucking back electrons. I dont know the logic of when etc. My last charging session had it for a few mins and then went to normal, but it gave me some quick range.

Do you you have L3 battery friendly charging enabled by chance? It’s the only thing I could think of. It’s not the onboard charger.

@Max Powers The EA 150kW chargers are actually 175kW (and the 350kW ones are just two 175kW ones bundled together). They can still handle voltages up to ~900V, but are limited to 375A.

At 400V, 375A is exactly 150kW, which is where the 150kW numbers comes from. With battery packs at higher voltages you actually don't hit the 375A limit, as the Taycan's 800V architecture only needs 220A to hit 175kW.

So EA is labeling 175kW chargers as 150kW because most cars can only get 150kW from them (at 400V). If you're getting more than 150kW from those chargers, it means the chargers are supplying power at higher voltages (which then again also means the internal 150kW 400V voltage doubler is not active).

I had to double check - It's not enabled

Great info, thanks! I still don't understand what the green lightning bolt and the charging boost relates to if not from the onboard charger option.

Guesses for what the icon means:
- direct charging is active
- DC charging is active
- charge rate is limited by the charger capabilities, not by the car
- ...?

I always get the lighting bolt even when AC charging at home. Simply denotes charging is in progress!

I assume you've never seen the bolt turn green then...

I see it green when it’s really fast at the beginning.
Like at Ionity at 269 kW

But not at the end when it’s slower.
Example latter on, same charge

 

[tigerbalm]

Its when charging rate is currently above 150 kW – the battery graphic/green box – also pulses during this part of the charging curve.

DOH!
