Achieving the desired output for a system requires proper designing and giving attention to each building block of the design. Adverse consequences prepare due to lack of attention to overheating, a critical component. 

When there is an excess amount of power in the system there is always a risk that roast running away, causing the battery to stop functioning, but presenting potential threats.

How To Avoid Overcharging?

Dedicate Smart Charging Functions: Most modern EVs are equipped with smart charging functions which stop charging once the battery has been fully charged, allowing such functions to be activated to avoid overcharging. 

Avoid Charging Over Extended Periods: Try your best to refrain from keeping your EV plugged in for prolonged durations and, if possible, overnight. If you need to charge overnight, use a timer to limit the charging time. 

Watch Out For Battery Limits: Avoid letting the battery deplete under 20% or exceed 80% charged for optimal battery life and longevity.

Tire Wear: A Unique Maintenance Problem 

Tires are an essential part of any vehicle. This includes EVs which seem to get overlooked by their owners when it comes to maintenance. Failure to take care of tire issues can result in increased wear and traction issues, or worse, a blowout. Maintaining tire health is paramount in assuring the EV runs in an efficient and safe manner.

Why Do Tires Wear?

Compared to traditional vehicles, EVs are heavier and have higher torque. This puts a lot more stress on the tires which, as a result, causes them to wear down at a faster rate than usual if not managed. Improper inflation of the tires to the correct pressure can also aid in heightening wear and drop fuel economy altogether. 

How To Reduce Tire Wear & Tear?

Consistently Inspect Tire Pressure: Inspect user tire pressure at least once a month, and prior to long distance travel. Keeping inflow up to the desired level can help increase the life of tires and fuel economy.

Rotate Tire Periodically: Move tires around each 5,000 to 7,500 miles mark to guarantee all tires wear at a similar rate. This helps increase the lifespan of the tires by minimizing wear patterns.

Examine Tires: Inspect the tires at regular intervals for potential damage such as cracks, swelling, and wear. These tires should be discarded immediately due to high potential for blowouts and threatening safety.

Regenerative Braking Issues: Maximizing Efficiencies

One of the distinctive features of EVs is the ability to recover some of the energy used while braking - also known as regenerative braking. Nevertheless, the improper application or lack of maintenance of regenerative braking systems can lead to poor performance, inefficient power recovery, and in some cases may even cause brake damage. 

Understanding Regenerative Braking

Regenerative braking is achieved by turning the kinetic energy possessed by a moving vehicle into electrical energy. This energy conversion not only recharges the vehicle’s battery, but also minimizes the deterioration of other brake parts through seldom usage. 

How to Avoid Regenerative Braking Issues?

Understand Your Vehicle’s System: Learn how your automobile’s regenerative braking system operates; this is important as certain vehicles have different ‘strengths’ or intensity levels for regenerative braking. Adjusting them can vary depending on the vehicle, so familiarize yourself with these features.

Use Regenerative Braking Wisely: It is highly recommended that the regenerative braking feature is employed frequently as this will maximize energy recovery. Other than helping extend the EV range, this will also slow down the wear and tear of various brake components.

Monitor Brake Health: It is crucial to always check how well your brakes and other components like brake pads and brake rotors are doing from time to time. Even though regenerative braking aids in reducing damage, it cannot be avoided completely. Always make sure brake parts are replaced in a timely manner so their safe functionality is guaranteed.

Disregarding Battery Health: Why Frequent Inspections Matter

Undoubtedly, maintenance is essential for any machine, particularly for the battery of your EV because it's referred to as the heart. Unfortunately, health check-ups are seldom performed by EV’s users, resulting in reduced performance and space over time. For a vehicle to perform effectively and last long, its batteries must be taken care of – the primary concern being the EV’s battery health.

Evaluating A Battery's Overall Wellbeing

An EV battery naturally experiences a gradual decrease in capacity over time; however, consistent and accurate health checks can avert these issues. Some consequences of ignoring the problem of aging include range reduction, charging inefficiency, and in some instances, total failure of battery function.

Prevention Against Battery Health Complications

Health Issues: Battery care instructions are best complemented with regular check-ups by a certified EV technician. These visits can significantly reduce the chances of encountering major issues later down the line. Greater preventative measures come alongside active maintenance.

Regulations on Battery Temperature: It is never recommended to maintain batteries around dangerous extremes for prolonged periods of time. If possible, keep your car parked in a garage or covered area to shield it from extreme temperatures.

Battery Management Systems: These have numerous functionalities and on top of maintaining the optimum health of the battery, they provide ample support in caring for the battery. Ensure that the stipulated guidelines from the manufacturer about caring for the battery, stipulating the use of these systems, are always followed.
