Yes, it's recommend.

I would not leave an EV plugged in continuously. They should not be stored 100% full. Changes in pack temperatures can over-volt individual cells.

If your vehicle is submitted to very warm or very cold temperatures, it can only regulate the battery temperature if it is plugged in. You will note that the manufacturer recommends you leave it plugged in in your owner's manual. The BMS actively protects against the overvolt situation, but the BMS becomes inactive if the vehicle is not plugged in.

It is a common misconception that leaving the vehicle plugged in will maintain 100% of charge. This is not correct. The BMS holds the pack at 80 to 90% of the pack rating for maximum health of the pack.
