Constant fast charging of the Ideal one is bad for the battery
Ideal one often fast charge compared to the battery, now a lot of charging fire accident is in the fast charge time, is not necessarily difficult to define, I personally think it is better to slow charge, if conditions or try to use slow charge
Long-term fast charging will definitely accelerate the decay of the battery.
I hope my answer helps you.
It shouldn't have much of an impact,
However, the battery of the car has a certain service life, and there is a fixed complete charge and discharge time, but the fast charging is not much impact, mainly because the temperature change will have an impact.
Other manufacturers support fast charging, proving no harm to the battery
