While it is possible to charge to 100%, it is not a great idea to do so regularly unless it’s absolutely necessary. Keeping the battery at 100% will speed up battery degradation which will decrease range over time. Additionally, charging slows down as you approach 100%, so charge times will take longer. Whenever possible, it’s a better idea to make more charging stops on a road trip to reduce the overall time spent charging (because the average charge rate will be higher). Tesla does recommend charging vehicles with LFP batteries such as the Model 3 RWD to 100% at least once per week when possible. This is because the battery management system (BMS) is not able to properly calibrate when the LFP battery is not at or close to 100%. This does not mean that there is no added degradation from charging to 100%.
