    Should I Charge My Tesla Every Night?

    Aug 01,2022 | Chloe Lacour

    One of the biggest concerns for new Tesla EV owners is how often to charge their batteries. Advice varies on whether you should charge your Tesla daily, every other day, or when the battery is below 20%.

    The best approach is to charge your Tesla every night. This helps increase your vehicle's range and maintain a healthy battery. However, you should use a low-voltage charger if you intend to charge daily. Make sure your battery is charged between 70% and 90%.

    Charge daily
    How often you should charge your electric vehicle depends on how many kilometers you drive every day. If you drive 37 miles a day, which is the average American driver, then you might only need to charge your car every two days. However, if you charge every night, your car will stay powered the whole time.

    The Tesla owner's manual states, "The number one way to conserve battery power is to leave the vehicle plugged in when not in use." It also states that there is no benefit in waiting to charge until the battery charge level is low.

    According to Tesla, your car's battery will stay healthy and perform optimally if it's plugged in daily when not in use. For this reason, you should charge your Tesla every night, especially during off-peak hours. If you only use 30% of the charge, you can charge up to 70% and be ready to go again the next day.

    Of course, there are some pros and cons to charging your Tesla on a daily basis. So, before you charge your car on a daily basis, you should consider what will happen to your car's battery in the long run.

    The benefits of charging a Tesla every day

    Keep the battery healthy
    The first benefit of charging your electric car every day is to keep the battery healthy. The battery will not drop below its lowest recommended limit which is 20%. Your vehicle battery is performing optimally when it does not drop below 20% or rise above 90%.

    Increase battery range
    Aside from keeping the battery healthy, charging it every day will help increase your vehicle's range. You will have plenty of juice every day when you leave your house. So you can cover more miles per day than someone who only charges when the battery is low or below 20%.

    Since the average American drives about 37 miles a day, your Tesla can run for at least 5 days on a full charge. However, if you charge daily, you can increase your range and commute between cities without problems.

    The cons of charging a Tesla overnight

    High electricity bill
    The biggest downside to charging your Tesla every day is that you will increase the cost of your electric bill. Unlike ICEs, Tesla vehicles use electricity. If you keep your car plugged in at home, the cost of your electricity bill will start to add up.

    Reduced battery life
    Another disadvantage of charging your EV every day is that you will significantly reduce the life of your battery. This is because daily charging increases the number of charge cycles in your battery. Most lithium-ion batteries last about 15,000 cycles before their capacity drops to 70% of a new battery.

    So if you charge daily, no matter what percentage you charge, the number of charge cycles will increase. In the long run, this damages the life of your battery.

    FAQ

    Why does Tesla recommend customers maintain a 20% to 90% charge?

    Tesla recommends customers maintain a charge limit of between 20% and 90% to keep the battery healthy. The main reason is to preserve battery health. Tesla EVs have lithium-ion batteries that require care to avoid damage.

    Lithium-ion batteries will be damaged if they spend a lot of time at the very low and very high end of the charge spectrum. This is also the reason why Tesla vehicles have a maximum charge limit of 90% by default. Tesla also recommends its users stay above 20%.

    Why does Tesla not recommend charging the battery up to 100% daily?

    Charging the battery to full capacity will drain the battery. This is because a higher charge percentage is associated with battery voltage, which is associated with shorter battery life. Instead, you should maintain a 20% to 90% charge to maintain battery health.

    What are the consequences of charging your Tesla over 90%?

    First and foremost, your battery will lose efficiency. Charging your battery past this point will drain it unnecessarily. In addition, the loading speed drops significantly. As a result, refueling takes longer and your electricity bill is higher.

    When should I expect the range of my Tesla to decrease?

    It is estimated that Tesla's range begins to decrease after approximately 185,000 miles. At this point, you should expect your Tesla EV's battery to deplete by 10%, which is not bad after many years of ownership.

    However, if you live in cold climates, your car may never reach its full range. That's because the range decreases as the temperature drops. The battery simply needs extra energy to run at an optimal operating temperature.

    When should I charge my Tesla to 100%?

    Only charge your Tesla to 100% if you plan to drive a longer distance. Let the car charge up to 90% overnight and fill up the remaining 10% a few hours before driving. However, you should try to stick to a loading limit of 70% to 90% as much as possible.

    Keep your battery between 20% and 90%.

    Depending on your driving needs, you can charge your Tesla either every night or every other day. However, to maintain the health of your vehicle's battery, it is best to charge up to 70% or 90% daily. In addition, you should use a low-voltage charge.

    For your battery to perform at its best, you should never allow the battery to drop below 20% or charge above 90%. Not only does this keep your battery healthy, but it also charges it efficiently within this limit. In addition, the range of the battery will gradually increase.
