NO! Bigger is definitely NOT always better! All EV batteries have a maximum amount of current they can accept while charging, without causing damage. As the battery nears full charge (80%+), the amount of current it can accept drops quickly, which is why the last 20% of charge takes much longer to complete. Because of this dynamic, in some cases a more powerful charger would simply not be able to charge your EV significantly faster, but would cost you more money to install.
In some cases this may make sense if the expectation is to upgrade your EV to one with a larger battery in the near future, but in many other cases it simply costs more for no benefit.
There is also a limitation on how much electricity can be supplied for any given EV charger, based on the electrical service at the property, and other loads already connected to the service. It may be, that there is not enough available to supply a more powerful EV charger (although there can be solutions to this situation, too).
Finally, the actual charging requirements need to be considered. How much time is available for charging, and how much range needs to be gained, in the available time? How efficient is the particular EV that will be getting charged, or will it be multiple different EVs (public space)?
The bottom line is, selecting the correct size of EV charging solution requires multiple considerations. There definitely is such a thing as ‘too big’.
