How to optimize the charge of your electric car?

Have you purchased an electric vehicle or are planning to buy one and are wondering about its charging method? The autonomy of your vehicle varies according to a wide range of criteria, but it is possible to optimize it to get the best benefits, that is, to achieve significant savings and preserve the life of your battery. How can you optimize your electric car’s charge? Let’s take a look at this case.

Charging an electric car: what about autonomy?

The autonomy of an electric car is a very random factor. It depends on the vehicle, the method of loading, the power transmitted, the displacements made in terms of duration and context, but also the equipment used (heating, demisting, defrosting, air conditioning, etc.) and the weather conditions.

Also, be aware that the capacity of a battery to store electricity decreases over time, as with any device that works with this type of equipment. Within five years, batteries would lose an average of 10% of their capacity, a normal degradation associated with component wear. This average varies depending on the time of use, the power of charge, the number of cycles of charge, etc.

The battery of an electric vehicle is one of the most expensive items. Before buying a used car, be sure to test its autonomy to avoid unpleasant surprises. You can request SOH delivery (state of health or “health status”) of the vehicle to the seller, a document that states the health status of the car and its battery.

How to optimize the charge of your electric car?

To drive your electric vehicle optimizing its range, it is a good idea to adopt good habits.

Aim for the correct upload window

The battery of an electric vehicle does not support full charge or full discharge. To prevent premature battery drain, be sure to keep your charge level between 20% and 80%. Also note that most chargers limit charging to 80%.

Regular use

As with any battery-powered device, the battery of an electric vehicle is not appreciated if it is not used for long periods of time. Therefore, you should avoid leaving your vehicle immobilized for several weeks. To keep your battery running at its best, it’s best to use it every day, even for very short trips.

Frequent spare parts

The longer a battery is charged, the more it heats up and therefore wears out. It is better to recharge your car more often, even to gain only 10% autonomy, than to drive 100%. In fact, the battery does not have time to heat up in these cases, which allows it not to wear out too quickly.

Rest assured, if your electric vehicle’s battery is guaranteed for a certain number of charge cycles, these are 100% cycles. Therefore, if you perform ten 10% charge cycles, this will correspond to a 100% full charge cycle and not ten charge cycles.

Ecological driving

With a combustion engine vehicle as with an electric vehicle, to consume less fuel or energy, it is preferable to adopt eco-friendly driving, which is more flexible. Heat is especially harmful to batteries, so it is recommended to limit excessive acceleration, especially in summer, as this causes the components to overheat. Similarly, a battery that is too full (more than 80%) gets much hotter.

Adopt a smoother, more pleasant driving style and try to park in the shade as much as possible.

A proper and slow charging mode

Recharging your electric car in record time, on a fast or ultra-fast terminal, is especially convenient. Waiting time is reduced. On the other hand, the battery overheats very quickly and therefore wears out much faster.

It is best to choose a reasonable power charging mode, not too fast. Slow loading does not heat up vehicle components too quickly. A classic charging station (3.7 kW to 22 kW) or a reinforced power outlet (3.2 kW) are the best charging solutions to preserve the battery.

Avoid driving before or after charging

If possible, you should avoid driving your electric vehicle before or after charging. Because ? Simply, again, by the rise in temperature. If you just drive, your car battery is hot. Therefore, the recharge will cause it to heat up even more, which contributes to its wear and tear. Similarly, after recharging, the temperature rise is larger, so it is best to avoid driving.

If possible, try to return the battery to normal temperature before and after charging to prevent overheating. You will see that you will also gain precious miles of autonomy.

Protected parking

As we have said, the battery of your electric vehicle does not tolerate high temperatures, but also extreme cold. Therefore, it is preferable for your car to sleep in a garage, protected from bad weather and summer heat, or at least under a roof. On the one hand, the heat causes the battery components to overheat, which tends to wear out much faster.

On the other hand, the cold has a significant impact. If you conserve battery power, it will reduce your ability to restore power. In addition, having a car at room temperature allows you to reduce the use of heating, defrosting and defrosting in winter, as well as air conditioning in summer, equipment that consumes a lot of energy, which therefore drastically reduce your autonomy. !

Aim for off-peak hours

To reduce the cost of recharging, favor low hours. Subscriptions that operate on peak hours and peak hours may offer variable peak hours, usually overnight. Sometimes it is possible to benefit from this advantage also at lunch time.

Feel free to check your energy contract for your off-hours. Also note that some wallbox models have the ability to detect only off-peak hours.
