To make good use of new energy vehicles means to grasp the professional knowledge about rechargeable batteries

Battery life anxiety is a common concern for people who buy electric cars for the first time.

Battery life anxiety is essentially a problem, so as an electric vehicle user, the most concerned thing is the actual life of the battery pack.

The experience of using mobile phones, tablets and laptops shows that their batteries will decay over time, so they need to be recharged more frequently.

But the good news is that electric batteries are more flexible than we thought, and there are ways to ensure that their batteries last longer than those found in most household appliances.

Battery life of electric vehicles

For consumers who switch to electric vehicles, battery life is one of the biggest concerns after continuing the mileage anxiety.

Just like your mobile phone or laptop, the battery of an electric car will decay over time and use, which means that their efficiency will decrease, and ultimately, your car’s range will decrease.

And the battery packs of electric vehicles are not as cheap as small appliances. When the batteries need to be replaced, the cost of purchasing the batteries will far exceed the actual value of the electric vehicle.

So replacing a new car is more cost-effective than replacing the battery pack.

Of course, if you don’t want to replace your car prematurely, you can extend the life of the battery by using it correctly every day, making it healthier and more efficient.

In addition, although the performance of the battery may decline over time, it has been tested by experts and car manufacturers that it can provide at least 70% of the electricity after driving 320,000 kilometers.

Why does the battery decay

The advancement of battery technology means that the problem of performance degradation has been decreasing.

However, even the latest applications cannot completely avoid performance degradation, and there are many factors that may affect it.

Perhaps the biggest reason for the decrease in efficiency is the use of the battery and the charging cycle.

often discharge the battery when fully charged, over time, it will damage the battery’s ability to maintain the best energy storage-this is why manufacturers usually recommend charging only 80%, and never let the cruising range completely drop to zero.

Fast charging will also cause the performance of the battery to decrease, because fast charging will cause the temperature of the battery pack to rise.

Although liquid cooling helps to alleviate this problem, fast charging is usually used. Over time, this extreme thermal cycle may cause damage to the lithium battery.

Similar, but not so extreme. When an electric car is used in hot weather, the performance degradation is much greater than when it is used in cold weather.

How to maintain electric car battery

Although the battery aging of electric vehicles is inevitable, there are some ways to help car owners keep the battery fully charged for a period of time and improve the efficiency as much as possible.

One of the main ways to protect a battery is to carefully manage its charge and discharge.

Ideally, this means keeping the battery at no less than 20% and charging no more than 80%—especially when the battery starts to heat up, which will affect its chemical performance.

Of course, if possible, it is best to choose electric vehicles that allow car owners to customize the charging time when buying a car.

This allows the user to decide when to charge the battery, and more importantly, set a maximum charge limit for the battery to prevent overcharging.

In addition, it is best not to completely drain the battery and cause excessive discharge.

Excessive release will cause irreversible damage to the battery, reduce the battery capacity, shorten the service life, and increase the internal resistance of the battery. Therefore, it is best to charge when the power is 20%, and the car owner should avoid parking the electric car for a long time, so that the battery is completely drained.

When charging, if conditions permit, it is best to use DC fast charging piles less.

Although charging is okay when fast charging is required during long-distance travel or emergency situations, the side effect is that the battery will heat up during an electric shock, thereby damaging the lithium ion.

If you use an electric car in extremely hot or cold weather, please make sure to fully charge it when parking (of course, up to 80%).

This keeps the battery’s thermal management system working and keeps the battery at an optimal temperature to extend its service life.

Finally, as an electric car owner, you need to understand that the way you drive an electric car also affects battery life.

Just like fast charging, the rapid depletion of the battery will cause damage, which will lead to a decrease in efficiency and battery life over time.

The faster you drive, the more you use the iconic lightning-like momentary torque of electric vehicles, and the more harmful heat you will generate in the battery.

So if you want battery life, it’s best to drive smoothly.

Electric car battery warranty

Manufacturers are keenly aware that expensive battery failures that occur prematurely may scare away many potential buyers of electric vehicles. But if handled properly, most lithium battery packs today can last as long as a car.

But in order to reassure customers, most car companies provide a separate extended warranty for the battery.

For example, Audi, BMW, Jaguar, Nissan, and Renault offer an 8-year battery warranty and a range of 160,000 kilometers, while Hyundai has increased the range limit to 20 Ten thousand kilometers.

Tesla also has the same 8-year warranty, but there is no mileage limit (except Model 3).

So when buying a car, it is best to look at the battery warranty clause. Most car manufacturers have stipulated that the battery warranty period should be able to maintain 70%-75%.

If the attenuation value is higher than this value, you can directly ask the manufacturer to replace it.
