Charging Infrastructure: If you have access to a home charging station or other charging infrastructure, it’s a good practice to keep your EV plugged in when not in use. This ensures that the vehicle can maintain its state of charge and, if necessary, take advantage of grid electricity during low-demand periods.

Do electric cars lose battery when parked?

Most electric cars will only lose about 2-3% of their charge a month while sitting idle. That means that if you had a car with a 220-mile range, you could expect to lose about 4.5-7 miles out of your whole charge over the course of a month. Avoid extremely high or low temperatures to help preserve charge.

Self-Discharge: All batteries, including the lithium-ion batteries used in EVs, experience self-discharge over time. Self-discharge refers to the gradual loss of charge that occurs even when the battery is not in use. The self-discharge rate can vary depending on factors such as battery chemistry and temperature.

Battery Management System (BMS): Most EVs are equipped with sophisticated battery management systems (BMS) that help monitor and manage the state of the battery. BMS systems can take measures to minimize self-discharge and prevent over-discharge, helping to preserve the battery’s health.

Parasitic Loads: Some energy is consumed by various systems in the EV, even when the vehicle is parked and turned off. These systems may include the onboard computer, security system, and climate control settings. However, the energy usage from these parasitic loads is typically minimal and should not result in a significant loss of charge over short periods.

Temperature: Extreme temperature conditions, such as very hot or very cold environments, can affect battery performance and self-discharge rates. Parking your EV in a temperature-controlled environment, when possible, can help mitigate temperature-related effects.

Can I sit in my electric car while it is charging?

Yes, it’s fine to sit inside an electric car while charging, as engineers have spent years making sure they’re fully insulated. The only exception to this is when you have certain medical devices inside your body which can be affected by electrical current, such as pacemakers.
