Hi all!
I am planning on assembling a 50kwh pack out of multiple Li Ion cells. I am planning charging with level 2 at 6.6kw and I was wondering if I need a battery cooling system when charging.

Active cooling: No
Passive cooling: Probably not
Depends on the the climate you are in and the pack temperature when you start charging.
Even temperature distribution is always a good thing.

I live in Ottawa, Canada. In the summer, days are on average 25°C and maximum in the low 30s. By passive cooling, you mean some air around the cells and a little fan to circulate the air?

Yes, by active cooling I mean with an airconditioning and passive cooling just using ambient temperature.
I wrote a blogpost about battery temperatures


Think you should be fine in terms of hot day temperature values, perhaps cold weather is something to think about. And as said temperature distribution perhaps.
