Electric vehicles (EVs) are becoming increasingly popular worldwide, and with this rise come many questions from new users about the details of using these cars. One of the most common questions is: Do electric cars lose charge when parked for long periods? What factors influence this loss, and how can it be minimized? In this article, we provide a comprehensive guide on EV charge loss while parked, based on the latest studies and practical experiences.
Do Electric Cars Lose Charge While Parked?
The short answer is yes—electric cars do lose a small amount of charge even when completely parked. However, this loss happens very slowly and generally does not cause concern for most users. If your car’s battery is sufficiently charged, you won’t face issues even if the car is left parked for weeks. Typically, the loss does not exceed a few percentage points of the total charge over a month of inactivity.
What Causes Charge Loss While Parked?
Electric cars use lithium-ion batteries, known for their high energy storage capacity and relatively low weight. However, these batteries experience what is called “self-discharge,” meaning they lose a small portion of energy even when not in use. Additionally, several other factors contribute to charge consumption while parked, including:
Battery Management System (BMS): Some EVs keep the battery management system active to monitor battery health, which may include heating or cooling the battery depending on climate conditions, consuming a small amount of energy.
Smart Connectivity Features: Many modern EVs remain connected to the internet or wireless networks to receive updates or enable remote monitoring, which uses some charge even when the car is off.
Cabin Climate Control: Some vehicles allow remote activation of cabin heating or cooling or maintain a certain temperature, which consumes energy if activated while parked.
External Temperature: Batteries are sensitive to extreme heat or cold, which can increase energy consumption to keep the battery within an optimal temperature range.
How to Minimize Charge Loss While Parked?
There are several practical steps to reduce charge loss in electric cars during parking:
Park in Suitable Locations: Preferably park in a garage or sheltered area to protect the car from extreme temperatures, reducing the need for battery heating or cooling.
Monitor Battery Health: Most EVs offer advanced diagnostic systems that allow drivers to track battery health and detect issues early.
Adjust Settings: Use energy-saving modes or scheduled charging features if available, and disable unnecessary features like cabin climate control or automatic updates during long parking periods.
Maintain Proper Charge Levels: It is recommended to keep the battery charge between 20% and 80%, and charge up to about 80% if planning to leave the car parked for an extended time to avoid deep discharge.
Should You Worry About Charge Loss During Travel or Vacations?
In most cases, there is no need to worry. If your battery is well charged before parking, the loss will be minimal. However, if you plan to leave the car unused for more than a month, it is advisable to ensure sufficient charge and check the car’s condition upon return.
Charge loss in electric vehicles while parked is normal and occurs very slowly. It does not pose a problem for most users if basic battery maintenance tips are followed. Continuous advancements in battery technology and smart management systems make EVs a practical and reliable choice for daily use and even during extended parking periods. If you are considering purchasing an electric car, do not let this issue deter you—it is simply part of the future driving experience.
