Should I Fully Charge My Tesla. You can adjust how full the battery charges from the charge settings menu. Utilizing a Level 1 or Level 2 battery charger to charge your Tesla in your home will cost about 15-18 based upon the price that we set at approximately 014 per kWh.

Level 3 480 V. The short answer is Teslas are pre-set to charge to 90 instead of fully maxing out the battery and this is by design to protect the battery long term. Level 2 240 V.
Constantly supercharging is not ideal for your battery because it tries to put in as may kW as it can.
This is a question that is quite common among both Tesla owners and non-Tesla owners who intend to become Tesla owners. Obviously if you own a Tesla you want to plug in at the Supercharger. The Tesla Supercharger is the fastest charging option when youre away from home allowing you to charge your car up to 200 miles in 15 minutes. This is Teslas recommendation.
