Want to Become a Hybrid And Electric Vehicle Mechanic? What It Takes To Maintain EV Batteries

Electronic Vehicle (EV) batteries are some of the most important components of the vehicles. Principally, they are responsible for storing and delivering power to propel the vehicle. Although EV batteries typically require minimal maintenance throughout their service lives, they can be quite expensive to replace. 

EV batteries can offer up to 15 years of service life. However, if an EV battery will fulfill this timeline will depend on how well-maintained it is. To ensure the longevity and optimal performance of EV batteries, proper maintenance practices are essential. In this blog post, we will explore the key factors involved in maintaining EV batteries for long-lasting performance.

Manage Temperatures Effectively After Hybrid and Electrical Mechanic Training 

Automakers are well aware that extreme temperatures, whether hot or cold, can pose significant challenges to battery performance and longevity. In response, they integrate auxiliary cooling and heating systems into their electric vehicles (EVs) to effectively manage and regulate battery temperature. These additional systems play a crucial role in maintaining the battery’s temperature within acceptable levels, thus protecting it from the adverse effects of extreme temperatures.

Temperature plays a significant role in battery performance and lifespan. Extreme temperatures, both hot and cold, can negatively impact battery health. To maintain EV batteries effectively, it is important to keep the vehicle parked in shaded areas during hot weather and avoid exposing it to direct sunlight for extended periods. In colder climates, preheating the battery before driving can enhance its performance. Furthermore, charging the battery while it is cold can be detrimental, so it is advisable to warm it up before initiating the charging process.

Hybrid and Electrical Mechanic Training Prioritizes Healthy Charging Habits

One of the best ways to maintain EV batteries is to use balanced charging. Balanced charging refers to charging all cells in an EV battery to an equal level. This practice helps prevent any individual cells from becoming overcharged or undercharged, which can cause imbalances and lead to premature degradation. Many modern EVs have built-in systems to automatically balance the cells during charging. However, it is still beneficial to occasionally perform a full charge and discharge cycle to ensure the balance is maintained, as you’ll learn in automotive school.

While fast charging may seem convenient, it can accelerate the wear and tear on EV batteries. Fast charging generates higher temperatures and puts additional stress on the cells, which can impact their longevity. Whenever possible, it is recommended to use regular or slow charging methods, as they are gentler on the battery and promote healthier cell performance.

Neither Fully Charge nor Fully Discharge the Battery

To maintain the longevity of batteries, it is important to avoid charging them to full capacity or completely depleting their energy. Fortunately, many manufacturers have implemented measures to prevent battery degradation. They have designed vehicles with settings that prevent full-capacity charging, thereby safeguarding battery health. Instead, these settings allow charging to a level below 100 percent. In fact, automakers often recommend charging EVs to around 85 or 90 percent for daily usage. By adhering to these guidelines, you can help extend the lifespan of EV batteries and mitigate the effects of degradation, whether you’re an EV owner or a hybrid and electric vehicle mechanic.
