As seasonal changes bring dropping temperatures and fallen leaves, electric vehicles (EVs) require specific maintenance attention beyond routine care, especially as drivers prepare for prolonged periods in cold weather. While fall can be a restful time, the transition to winter demands careful preparation to keep the vehicle operational and safe from elements like snow and ice.
Protection and Storage
A primary method for safeguarding an EV during cold spells is proper sheltering. Parking the vehicle overnight in a garage is the most effective measure, as it maintains a stable, warm environment, protecting it from harsh weather. Although less enclosed, parking structures or carports can also provide a degree of necessary protection.
Handling Snow and Ice Build-up
While all vehicles need clearing when snow falls, EVs require extra diligence. Because many manufacturers incorporate unique or non-traditional door handles, these components are more susceptible to freezing in place. Furthermore, it is crucial to ensure the charging port door is thoroughly cleaned to prevent it from becoming frozen shut and inaccessible.
Optimizing Battery Performance Through Preconditioning
A vital aspect of EV maintenance is understanding and utilizing the battery preconditioning feature. This process stabilizes the temperature of the vehicle’s main battery pack within an optimal range, which significantly enhances charging efficiency and overall performance. Manufacturers allow this process to be initiated either through the car’s charging settings or via a companion smartphone application. Notably, the preconditioning function is designed to manage temperature extremes, offering warming capabilities during winter and cooling capabilities during summer.
The Importance of the 12-Volt Accessory Battery
Electric cars utilize large traction batteries to power the motors for driving. However, they also contain a separate 12-volt battery, similar to those found in traditional gasoline cars. While this smaller battery does not power the primary driving mechanism, it is essential for operating numerous auxiliary systems, including the vehicle’s lighting, climate control, infotainment system, and even the charging settings. According to a blog post from Battery Tender, “Electric vehicles eliminate many maintenance tasks, but one critical component remains: the 12V accessory battery.
This small battery powers essential systems and can strand you even with a fully charged traction battery.”
