Understanding Electric Car Battery Behavior During Quarantine

As the world continues to grapple with the COVID-19 pandemic, many people are staying home and using their cars less frequently. This change in driving habits has led some electric vehicle (EV) owners to notice a decrease in their car's battery capacity when parked for extended periods. In this blog post, we will explore the reasons behind this phenomenon and discuss best practices for maintaining your EV's battery health during these unprecedented times.

Paragraph 1: The Importance of Battery Management Systems

An essential component of any electric vehicle is its Battery Management System (BMS). The BMS monitors and controls the charging and discharging of the battery pack, ensuring that it operates within safe limits. One crucial aspect of a BMS is estimating the State of Charge (SOC), which gives drivers an idea of how much energy remains in their battery. However, it is important to note that the SOC provided by the BMS is not always an exact measurement but rather a "best guess" based on various factors such as temperature, voltage, and current.

Paragraph 2: Charging Behavior Changes

Recent software updates have altered the way some electric vehicles manage their batteries while connected to a charger. Instead of continuously topping off the battery, these vehicles now initiate charging only after losing a certain amount of charge first. This change prevents trickle charging, which can be harmful to some battery chemistries like lithium-ion batteries used in most electric vehicles.

Best Practices for Maintaining Your Electric Vehicle’s Battery Health

With more people staying at home due to COVID-19 restrictions, it's essential to understand how to maintain your electric vehicle's battery health during this period of reduced usage.

Paragraph 1: Monitoring Energy Consumption

One issue that may arise from leaving your electric vehicle parked for extended periods is increased energy drain overnight. To minimize this drain, ensure that your car enters "sleep mode" when not in use. Additionally, consider switching your battery display from "distance" (miles) to "energy" (percentage), as this may provide a more accurate representation of your vehicle's current SOC.

Paragraph 2: Balancing Charging and Discharging

While it is generally safe to leave your electric vehicle plugged in during periods of low usage, it is also essential to allow the battery to discharge periodically. This practice helps the BMS maintain an accurate estimate of the battery's SOC by exposing it to a wider range of charge levels. If you notice a significant drop in your vehicle's available range or capacity, try taking it for a drive to help recalibrate the BMS.

Paragraph 3: Maintaining Your Electric Vehicle During Quarantine

In conclusion, understanding your electric vehicle's battery behavior during quarantine can help ensure that it remains healthy and ready for use once restrictions are lifted. By monitoring energy consumption, allowing periodic discharging, and staying informed about software updates affecting charging behavior, you can keep your EV running smoothly throughout these challenging times. And remember, while it might be tempting to worry about every fluctuation in battery capacity, sometimes the best advice is simply to trust your vehicle's systems and focus on other aspects of life during this unprecedented period.
