The FAQ “Should I charge my EV every night?” is situational, while the answer to the second question is yes. EVowners can and often do leave their vehicles plugged in overnight. Since EV batteries are designed to stop drawing electricity once they reach a predetermined level, the various concerns with the practice of leaving EVs charged while owners sleep are insensible.
Meanwhile, the answer to the question “Should I charge my EV every night?” hinges on the owners’ driving habits and the vehicle’s range. For instance, plugging in their vehicles every night would be necessary if they drive more than 100 miles each day and have a car with a 200-mile range.
Having said that, the daily average for US drivers is 40 miles, so it is certainly insensible to plug in and charge every day in that case. While most EV drivers only plug in every second or third day, there is no danger in doing so every day or every night.
There are certain advantages as well in plugging in every night. For instance, EV owners are considerably less likely to forget to charge their vehicles when needed if they plug them in every night since it has become a strong habit.
Additionally, charging every night allows EVs to be well-charged for unusual days when owners need to drive longer than anticipated.
However, it is worth noting that charging electric vehicles to 100% should not be practiced. It is because batteries degrade the closer they are to 100% or 0%, especially if sitting there for long periods.
People frequently advise keeping battery charges between 20% and 80% to be practical. If necessary, it can be close to 40% to 60% as much as possible. Therefore, it is crucial to set the charge limit to 70%, 80%, or 90%, not 100%, if EV drivers would plug in their cars every day or every night.
