Electric Vehicle Batteries: How to Charge and How Long They Will Last

Electric vehicles are becoming a new reality for all inhabitants of the planet. We can see an increase in the number of eco-friendly cars on the roads every year as people start to take the issue of environmental protection more seriously.

Such cars can not only be bought, in which the states of some countries help their citizens by providing subsidies and exemption from transport tax, but also rented in different countries of the world. Dubai car rentals provide customers with a large selection of for-hire electric cars for their clients. Everyone, depending on their needs, can use hourly car rental Dubai, or rent a car for several days and even a month. In addition, car rentals offer competitive prices, as well as first-class service.

Those who are going to buy such a car, opting out for the car with an internal combustion engine, are wondering how long the battery of an electric car will last before the degradation process begins.

Li-ion batteries

Many are aware that such batteries are installed not only in electric vehicles, but also in all modern smartphones, laptops, and various devices. As practice shows, the owners of such devices can only enjoy a good battery for several years before the battery capacity starts to deteriorate and the device needs to be charged more often.

In this regard, many are concerned about whether the same will happen to their car battery since such batteries are more expensive than smartphone batteries.

It is worth understanding that factors such as the way they are discharged and recharged, as well as the temperature environment in which it is located, affect how long a battery will last.


The most intensive use of such batteries is to charge them from zero percent to full charge. If you discharge and charge the device in this way, you can thus charge the device about five hundred times before the maximum capacity value starts to decrease.

Famous smartphone manufacturers are betting on this so that customers update their devices after 2 to 3 years. In the case of electric vehicles, since they are designed to last approximately ten years, if their battery starts to degrade after two years of use, this is bad news for the industry. Fortunately, batteries in electric vehicles can be serviceable for a longer period.

Battery buffer

In the production of batteries for electric vehicles, protection called a battery buffer is used. This means that even if your car indicates that there is 0% charge left, then, in fact, there is a supply of electricity in the battery. This is done to delay the start of battery degradation as long as possible. That is you can only discharge the battery up to 15%, and charge up to 90%. As a result, you use your battery less intensively.

When compared with other Li-ion battery devices, the battery of electric cars can be charged more than 1,000 times in this way. One of the worst things you can do is completely drain your battery and leave your electric car without recharging.

In this regard, Elon Musk recommends that owners of electric cars discharge the car up to 30% and charge up to 80%.

Temperature regime

In addition, automakers have made sure that the battery is in the correct temperature range. In general, the best temperature for such batteries is 20-23°C. Temperatures that are too low or too high can shorten the life of such batteries.

A large number of electric vehicles are equipped with special temperature control and management system. In this system, the main component is liquid cooling, which does not allow the batteries to overheat.

Electric vehicles are the new future for all car owners, as automakers will begin to move away from the production of petrol cars.
