Do I need to charge my Tesla at night?

You have complete discretion over whether to charge your Tesla every evening.  

You may certainly plug in every night if you'd like to because your Tesla's battery is made to handle daily charge.  

For optimum performance, the typical advice for Tesla owners is to maintain your battery between 50 and 80% of its capacity.  

In light of this, if it suits your needs, you can choose to charge every night up to 80%. You might be able to charge your Tesla less frequently,  

like once a few days or once a week, if you don't use it frequently.  

The best course of action is to monitor your battery level and choose what suits you the most.
