Agreed, the adaptive/regenerative charging works the battery pretty hard, and short trips especially. The very first thing the shops do is to charge the battery when one comes in - it takes a lot of questions off the table.

This is one reason the car is equipped with an AGM-type cell. These are good for deep-discharge and large reserve. The charging algorithms depend on it for their efficiency. Topping it off with a proper charging unit during times of light use is a good thing IMO.
