How Long Do Batteries Last In Vehicles A What Affects Their Lifespan?

Motorists in Bristol and throughout the UK are switching to electric vehicles due to the increased price of petrol and diesel. How long can electric car batteries last? Hybrid and battery-powered electric cars have been commonplace since the dawn of the 21st Century, and technicians and drivers have ample experience with the new technology. Many drivers who switch to electric have to worry about range anxiety. Battery degradation is another reason used car buyers need to be concerned. This happens especially as there are more cars to choose from, with more owners and close to the manufacturer's end-of-life date. The same happens to EVs. Just as your phone battery might not be as powerful as it once was, so may your cellular phone. Reduced capacity will eventually affect range and performance. This guide will discuss the factors that affect battery life in electric and combustible cars, what you can expect from degradation, and how to maintain the optimal performance of your car's batteries.

Which Type of Batteries Are Used in Modern Electric Vehicles?

To store energy, full EVs require a large number of cells. The cells are similar to those found in mobile phones and laptop batteries. They can be charged quickly, store energy efficiently, and can be used for thousands of charges without losing their charge. As with phone and laptop batteries, their life expectancy can be affected by how well they're charged. Also, as they age, they may experience failures that could cause the entire system to fail. Dealers often opt for the simple, expensive approach to replacing the whole module, which is equivalent to replacing the entire engine because your water pump has failed. You are better off getting electrical problems diagnosed by trusted auto electricians with the expertise and equipment to diagnose electrical faults at their source.

What Causes The Battery Life Of Electric Vehicles To Degrade Over Time?

Similar to how a cell phone battery eventually fails, electric car batteries will lose their capacity over time. The chemistry and materials of the battery are the same after they've been recharged, but the structure of the cells is altered. The lithium portion of the "lithium-ion" pairing eventually forms internal spikes that can reduce the cell's area and damage the protective layer. Fast charging and charging at full charge can make this worse. This is why most EV makers talk about charging up to 80%. This is the best way to prolong battery life. The latest iPhones even allow you to defer charging until your full charge has been reached. Modern EVs have a high-capacity battery because they are equipped with more battery cells and better battery technology. Many older EVs are still in good condition after thousands of miles of travel. A decade-old phone may need to be plugged in for work daily, but a decade-old Electric vehicle can still provide a reasonable range.

How Does Rapid Charging Affect Your Battery Life?

Rapid charging is a method that can significantly reduce charging time. Rapid charging uses direct current (DC), which charges your batteries faster than traditional methods, and this means you won't need to wait for them to charge. Fast charging can accelerate battery degradation, and the higher heat generated during rapid charging could eventually cause damage to the batteries. If you plan to use quick charging for long distances, it can be costly.

How Can Other Factors Affect The Life Span Of An Electric Vehicle's Battery?

The best way to reduce a battery's power is to drain it constantly and recharge it at 100%. If a battery is allowed to drain completely, it can cause damage. The good news? Most manufacturers design their systems to have a buffer at each end of the battery's capacity. Most systems don't charge to full capacity. Instead, most manufacturers keep a reserve to protect the battery from being damaged by excessive driving. Your battery life can be affected by how you drive. Although EVs can boast impressive acceleration and launch control, too many of these actions could lead to faster battery wear. Before doing rapid accelerations at every traffic light, keep in mind that it drains your battery and accelerates battery degradation.

Systems & Factors Which Acccelatate The Drainage OF Your Battery

The wipers work overtime to remove torrential rain from the windshield, and the headlights turn on full beam to see corners of unlit roads ahead. The climate system, four heated seats and the temperature control do everything they can to warm you on cold winter nights. The navigation system adjusted the range to reduce the distance between your destination and your car's remaining range. Every EV owner is now playing a game of mathematical brinkmanship. There's also a possibility you might not make it. Can you prolong the life of your battery by turning off some electrical devices? When you are nearing single-digit charges, the real question is, "Would any of these things make a significant difference?" If so, how much? Can you earn extra mileage by not using warm air or turning off the radio? There are many surprises and complicated answers.

The Battery Temperature Is A Factor

What is the importance of battery temperature? Specific chemical reactions can limit the performance of a cold battery. Current automotive cell chemistry does not perform well at low temperatures. It cannot withstand high currents or charging and discharging. Lithium plating can occur if the cells are exposed to high temperatures. It is similar to corrosion and can cause battery degradation and ageing. An EV can accept more power than a charger will provide. A charger may always deliver the power stated, but it cannot supply all of its power. The charging speed is controlled by electric vehicles to ensure the safety of the battery. This is called the 'charging curve for electric cars. Winter is when fast charging takes longer than any other season. This is due to the 'battery temperature. The temperature of an EV battery has a significant impact on its charging speed. It can often drop to below zero degrees. The ideal temperature for an EV battery is between 20-40° depending on its model, and this can prove not easy in winter. Temperatures below this temperature will impact the charging speed and the range because as the temperature decreases, the battery's electrochemical process slows down.

How Important Is Weight In Power Consumption?

An electric car's consumption can be affected by passengers or luggage. An EV's regenerative braking system helps offset some energy loss caused by lugging more weight, which is impossible with an ICE car. The extra weight and momentum increase the vehicle's mass, which in turn boosts the energy recovery rate when coasting or braking.

What Can You Do To Avoid Slow Charging In The Winter?

Although it is challenging to prevent cold batteries from winter, there are ways you can avoid slow charging.

  • Preheat The Battery: Many EVs offer the option to heat the battery before going on a driving trip or as a stop at a charging station. The car will prioritize heating the battery to reach operating temperature, so power is not diverted during charging. If your model permits, we recommend you preheat your EV's battery.
  • You should wait to charge your electric vehicle: If your car cannot preheat your battery in advance, you can leave it idle for as much time as you have. The battery will have time to cool down, which makes charging more manageable and quicker. Regeneration may be an option to heat the battery. Accelerating quickly can increase temperature, but we don't want to encourage reckless driving.
  • You can park your car inside: We understand that not everyone will have this option. However, if they do, keeping the vehicle in a warm environment is a good idea. You won't have to heat your car as often, and the battery will not become as cold.

Battery Maintenance

These advanced batteries are limited in their charging cycle (also known as "cycle life", the number of charges that can be made to the battery). Ask the dealer for information about warranties and battery life. Also, be sure to review the battery recycling policies of the manufacturers. To maintain operating temperatures, some automotive batteries use liquid cooling. Regular checks may be required for these systems. If you would like more information about having your vehicle serviced or its battery replaced, you can contact an auto electrician in Bristol, as using an auto electrician is usually cheaper than visiting your dealer directly. Most batteries used in electric-drive cars are designed to last the vehicle's lifetime. The advanced batteries in electric cars (EVs) are similar to conventional engines but will eventually wear out. Although there is no comprehensive information on EV battery failures, many manufacturers offer eight years/100,000 miles warranties for their EV batteries. Although manufacturers don't usually publish prices for replacement batteries due to the fact that warranties do not cover them, it can be costly if the battery needs to be changed outside of the warranty. As technology advances and manufacturing volumes rise, however, prices for replacement batteries are likely to drop.
