For electric cars, its most expensive part is a power battery, so how long it will be considering the battery when purchasing electric vehicles. According to the current battery level, if the electric car's battery is used, it can be used for ten years. According to Nissan and General Motors and other car manufacturers, the current warranty policy is eight years or 160,000 kilometers.

How long can the battery not only depends on the quality of the battery itself, but also how usually use it. At the time of visiting a Japanese catering enterprise, and communicating with its senior engineers, the author is aimed at this exchange of content and experience, summing up how to use the battery correctly, extend the battery life, and provide a few "immature" Small recommendations for reference, this is an important industry secret 喔. 1.

Avoid battery charging over the battery cannot be filled with electricity, that is, often charge the battery, which will affect the battery life. About this reason, we can use only three or four years from now on the most common mobile device. For example, the mobile phone commonly used in our daily lives, such as Apple iPhone6S, or Xiaomi mobile phone, Huawei Mate7 mobile phone, etc.

, most of the situation is completely exhausted, then completely full, so, often Complete charging, this is actually a very serious damage to the lithium-ion battery, and the result is that the mobile phone battery has been in three years. For example, the electric car Leaf of Nissan, there is an improvement of the battery life, so that the battery is charged to 80%, which reduces the mileage, but can greatly improve the service life of the battery pack. This setting is completely satisfied with only the daily get off work that is for daily, the key is to improve the easiest way of battery life.

For electric vehicles, it is not suitable for electricity, there is another reason, that is, when the electric vehicle is braking or downhill, it is necessary to recover some of the energy and return to the battery, then this requires a certain charging space in the battery pack. During the driving process, when it is uncertain when it is necessary to reproduce brake to the battery. 2.

For pure electric vehicles, the battery pack avoids depth discharge to the pure electric vehicle, avoiding the charging of the charge with the above, avoid depth discharge. One of the characteristics of the lithium-ion battery is partial cyclic use without depth, there is no memory effect for lithium ions, so it has no effect on the battery using local discharge, and does not reduce the battery capacity. During the Nissan Listening, there is a scale of 12 battery charges on the dashboard, which generally allows you to maintain the amount of electricity at 3-10, which is within this period.

For a better battery energy management system, when the battery power reaches a certain threshold, it will give a warning. "How far you still need?" To remind you to make up according to the itinerary. 3.

For plug-in hybrid vehicles, you can consider using "Mountain Mode" based on the above-mentioned avoidance of battery excessive discharge. For Toyota Prius plug-in hybrid car or increased range electric car, such as Chevrolet Volt, BMW I3, almost It is the mode of the battery and then switch to the petrol engine. Fortunately, because there is a battery management system, you know when to stop using the battery, avoid depth discharge.

However, there is a situation that there is no way to identify the current battery management system, that is, in your driving route, there is a long-range driving operation, if it is a flavor, it is easy to use The battery is exhausted, and the other may cause the battery depth discharge. If you can work mode, switch to the mountain mode before climbing, it is the mode of the engine work, or select a point in the EV mode, which can save at least 20% of the battery. In addition, there is a need to explain that, in fact, Toyota Puri's operating system is provided with a similar operational option to the driver, so that the vehicle exits the pure electric mode, which can use gasoline in this section, and the battery is less.

4, use the timing charger to minimize the time on the high-charge state, in many cases, will choose to charge late at night, so that the load on the grid is small, but the electricity bill is relatively cheap, but this is very likely Charging is full. So how do you guarantee that the battery can be kept in the best charge? For example, suppose it is only 50% of your power, but this 50% is difficult to maintain your next day's itinerary, at this time, the battery can only be charged for 60 minutes, so you can reach 80%, to meet your second Day driving needs. So, this time, there is a need for a charger with a timing function to ensure that the battery is reduced in the high-charge state.

In fact, this charging timer, there are other applications, for example, in the usual, there is no need to keep up on the car waiting to be charged, you can make a charging at any time, people can do other things, and for the merchant, you can Provide a timing fee; in addition, it can also make the battery to be charged. The time is cooled. Summary about the maintenance of electric vehicles, especially the maintenance of the battery, especially the key, especially to remember this basic criterion, avoid overcharge, and avoid excessive discharge.

The battery management system is also managed based on this principle. Of course, the process of use also needs to follow this criterion, so develop a charger with timer function, it is particularly important, maybe, this is also an entrepreneurial project.
