For EV drivers, it is important to know how long you can leave an electric car unplugged without damaging the battery. Keeping your parked EV healthy with these simple tips will go a long way.
Do Electric Cars Lose Charge when Parked?
EVs are designed so that they lose charge while parked but at very minimal amounts and after even just one day of driving it’s back up to 100%. However, Green Car Reports suggest charging your EV 80% before leaving them for storage because over time this could add up. Experts also agree that vehicles should have 50% or more power in their batteries before parking them. This will provide enough energy to start the vehicle once again if there were some type of emergency like being stranded.

Do EV lose charge while parked? Users reported a range loss of up to 2% to 3% overnight.
After 14 days when the Li-ion battery available charge gauge reaches a zero or near zero (state of charge) avoid leaving your vehicle. Park/store your vehicle out of direct sunlight and away from heat sources in locations with cool temperatures.
According to experts, EV batteries can be damaged if left uncharged for a long period of time and in some circumstances even shorter periods like when at work or sleeping overnight. Experts also recommend charging the battery with a NEMA 14-50 home charger or supercharger before storing it, as this can cause damage over time.
Charging EV batteries on a regular basis helps them retain their ability to hold charge. However, there are still benefits from unplugging an EV for short periods of time like when parked at work or overnight while sleeping. Experts agree that this will not hurt because it is only temporary and after one day of driving it’s back up to 100%. So as long as they’re charged 80% before storage then you can go ahead and park your EV without worrying about damaging the battery.
Never allow the battery to completely drain
Even when an electric car is parked, its battery slowly discharges in order to power the car’s electronics. The battery can discharge at a rate of around 1% per day but this rate may vary depending on environmental factors and the vehicle configuration.
Consider taking time to fill up your Tesla before parking it. In situations where you must leave a Tesla unplugged (for instance, at an airport while travelling), keep the remaining battery charge in mind. Over 14 days, the car’s battery may discharge by as much as one percent if not filled with enough charge beforehand — especially when plugged after driving on electric only for long distances and no other charging is done during this time period.
0% displayed charge level
When parking your electric car, avoid fully discharging the battery. To protect against a complete discharge when not in use, your Tesla enters low-power consumption mode at approximately 0% displayed charge level and may lose key features like headlights or back up camera that rely on the 12V battery.
If your vehicle does not start, wait and try to reset the keys. If you cannot reset it externally or your car still will not start afterwards, then try to contact the automaker for further information on how to troubleshoot an issue with electrical vehicle starting problems or get a certified mechanic at a dealership if near-by.
EV cars do lose charge when parked but only in small amounts. EV owners should know the basics about parking their vehicle and how to protect it against.
