How correctly use the power lithium battery to extend the service life?

How long is the battery can be used, but also depends on the quality of the battery itself, but also how usually use it. When visiting a certain Japanese car company, the author exchanges with its senior engineers, the author is aimed at this exchange, summing up how to use the battery correctly, extend the battery life, and supply several“Incorrect”Small proposals for reference. Regarding electric vehicles, its most expensive part is a power lithium battery, so it will consider how long it will continue to use when purchasing electric cars.

According to the current battery level, the electric vehicle's battery is used normally, it can continue to use a decade, according to Nissan and General Motors and other car manufacturers' current warranty policies for eight or 16.0 million kilometers. How long is the battery can be used, but also depends on the quality of the battery itself, but also how usually use it.

This article is important to summarize how to use the battery correctly, extend the battery life, and supply several“Incorrect”Small proposal for reference. 1. Prevent battery charging over the battery cannot be electrified, that is, the battery is often overwhelming, which will affect the battery life.

For one of this original, we can use only three or four years from the most common mobile device from now on. For example, the commonly used mobile phones in our daily lives, such as Apple iPhone6S, or millet mobile phone, Huawei Mate7 mobile phones, etc. 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 increase in 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 fully satisfied with only the daily business, the key is one of the easiest ways to improve battery life. Regarding the electric car, it is not advisable to overflow, there is another original, that is, when the electric car is braking or downhill, it can recover some of the energy and return to the battery, then this should have a certain charging space.

During the driving process, when is not sure when to make a brake to charge the battery. 2. About pure electric vehicles, battery packs prevent depth discharge About pure electric vehicles, to prevent the charging of the charging from the above is to prevent depth discharge.

One of the characteristics of the lithium-ion battery is that some cyclic use cannot be depressed, and there is no memory effect on the lithium ion, so the use of local discharge does not affect the battery, and the battery is not reduced. 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. With regard to a better battery energy management system, when the battery power reaches a certain threshold, a warning will be issued.

“How far is you still?”To remind you to charge according to the itinerary. 3. About the plug-in hybrid vehicle, you can use it“Mountain mode”Based on the above-mentioned prevention of over-discharging, there is almost all the battery, such as Chevrolet Volt, BMW I3, etc.

Fortunately, because there is a battery management system, what should I stop using the battery while preventing depth discharge. However, there is a situation that the battery management system in this chance has not been identified, that is, in your driving route, there is a high-power drive driving situation in your travel route. If it is a flavor, it is easy to use it.

The battery is exhausted, and the other may cause the battery depth discharge. If you can switch the working mode, switch to the mountain mode before climbing, or the engine works, or select a point in the EV mode, which can save at least 20% of the battery. In addition, it will be explained, in fact, in fact, Toyota's operating system is provided to supply a similar operational option to the driver, so that the vehicle exits the pure electric mode, which can use gasoline in this period of time, and the battery is less.

4, use the timing charger to minimize the time of charge in the high-charge state, in many cases, will choose to charge late at night, which affects the load of the grid, and 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, assuming that when your power is only 50%, this 50% is difficult to maintain your next day's itinerary, at this time, the battery can reach 80% as long as it is charged for 60 minutes, there can be 80% to meet you the next day. Driving.

So, this time, 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 use purposes, for example, in the usual, don't keep up on the car waiting to be charged, you can make a charging at any time, people can do other things will come back, and about business, you can supply Timing fee; additionally, it can also make the battery to be charged. The time is cooled, to ensure the safety of the battery when driving, of course, this is not in the extremely cold area.

Summarize the maintenance of electric vehicles, especially the maintenance of the battery, especially the key, especially to remember this basic criterion, prevent excessive charging, and prevent excessive discharge. Battery management system is also managed based on this principle. Of course, the process of use must follow this criterion, so develop a charger with timer function, which is particularly important, maybe, this is also an entrepreneurial project.
