How to make electric car battery life (Summary) I am important to make the original life of electric car battery life (original article), and finally summarize some attention. First of all, by the battery itself and the original origin of the battery, this is what we can't control, what we can do, then there is only to choose. The battery manufacturers in this chapter are dazzling, the quality is different, how do you choose a battery to become a problem.

First, we consider the brand (I refer to the battery brand, not electric car brands). Why have some electric car brands? Because, even if there is a famous brand! Many dealers are often used for interest and returns. It is often not using the original manufacturer brand battery, but the local life of the factory.

So, everyone will leave a heart when buying a car, can ask what brand of batteries. If the money is permitted, try to choose brand batteries, such as Super Wei, Tianmeng, Panasonic, expensive, you can have more trustworthy, if the price is unbearable, then choose some (all places) Good reputation, Modular battery. Don't be cheap.

Second, consider the after-sales service. After-sales service is guaranteed. Clear the true guarantee of the battery.

Some maintenance organizations will be treated as a warranty period of the battery, especially the time to replace the new battery. Generally, the new electric bicycle, generally a year warranty, the amount of half a year is less than 60%, can be replaced new, half a year to one year Replace the battery after re-enrolling the group; and electric motorcycle, generally for half a year to eight months warranty, three months of content, less than 60% can be replaced, three months to warranty end replacement by manufacturers Battery. I once asked me why 14ah's battery was light than 10ah battery! The larger the battery of the same rated voltage, the larger the battery quality (weight), the bigger the 14ah battery is a fake 14ah battery, in fact it is 10ah, this is a promotional means of the merchant (say it's deceived Not completely, because it is possible to use the 20-hour rate (20HR) to discharge the result, but according to the national standard is 2 hours (2HR), it should be 10ah), because the capacity is more The battery, the more expensive, and the distance runs farther.

Regarding the battery, I just talk about the above, because of the biggest problem with us, let's keep the use of electric car battery longer. About lead-acid batteries, what is the most important reason for its life? vulcanization. The right is vulcanization, and we have already said that as long as it is a lead-acid battery, it will vulcanize in the process of use, we can't handle it, but we have a way to reduce the sprouting of the vulcanization, this is what we can control, and we are As mentioned earlier, the original source of sprulgization is also said: the large current discharge, can not be charged in time, depth discharge, frequent charging, the charging time is too short, the factor caused by the charger itself, etc.

To reduce the vulcanization of the battery, extend the battery life, first improve the environment of the electric bicycle: 1. Leverage heavy objects, control the speed and brakes, prevent large current discharge. When accelerating, especially when starting, you should slowly turn the turn, sometimes you can stop, and you will continue to accelerate when you stand.

During the driving process, it is not appropriate to start, brakes, if the brakes are in the case, can release the turn in advance, try to let the car drive against the inertia. In this way, it can prevent the damage of the battery from the battery, but also the mileage of the battery. 2.

Timely charging. After use, it should be charged in time, preferably no more than half an hour, if necessary, if you don't have to use it, you have to ride a few, and the interval is relatively long, then you can choose to charge at night, and should appropriate Extending the charging time is 1-2 hours, that is, after the turning light (because each charger is not the same, I will collect it here, I don't say that the green light does not jump green light, or the other, the same) 3 -5 hour. If the mileage of the day's riding is greater than or equal to 50%, then it will be charged every day (determining that if you are no longer used), if your ride is less than 30% of the last mileage, you can choose to charge it for two days, if Less, you can extend proper, but you can't over 3 days.

It should also be appropriately extended. In general, you should pay attention to: It is best not to unplug the power to use it when you use it. It is not appropriate to frequently charge the battery because the charging and discharge cycle of the battery is certain, generally 300 times, frequent charging of the battery will increase the active substance of the battery positive panel to soften, which will cause the grid corrosion to accelerate.

Regular depth discharge. Regular deep discharge is also a good way to maintain battery capacity, what is this? It is not to say that the lead-acid battery has no memory effect, why should it be deeply discharged? Detiled originally made a comment at the end of the comments, all of them have seen it. At this point, I would like to wait for everyone to say my opinion, please don't see it! As for the cycle, the battery is generally purchased for three or four months, starting from four months to eight months, every two to three months, once a year, one year.

In fact, this method is more suitable for those who have a small number of days, because many people are very irregular, who can guarantee that there will be no one half of sitting to sit down to under pressure protection. So you don't have to completely follow the imitation, you will know how to have such a thing. Perhaps someone will ask, don't you charge it in time? Otherwise, it is easy to cause vulcanization.

That's right, but: when shallow is discharged, the lead concentration of sulfate is not very large, the crystal is slow, less, has not become a large crystallization, compare can be used to remove vulcanization. For example, when charging, it is positive and negative pulses, over charge method, etc. And we rose floating time, you can have a certain alert use of the vulcanized battery.

3. Do a good job of undervoltage protection, prevent the minimum protection voltage of the depth discharge {12V lead-acid battery is 10.5V, if it is a 36V battery pack, the minimum protection voltage is 31.

5V, currently most of the vehicle factory uses controller undervoltage protection voltage Are 31.5V. It is feasible on the surface, however, when only 31.

5V voltage left, only 31.5V voltage left, due to differences in the battery, there is certain that a battery voltage has been below 10.5V, the battery is in an over-discharge state.

At this time, the battery capacity of over-discharge has dropped sharply, and the concentration of sulfate has increased, salted, and the damage to the battery is very large. In fact, the impact is not only the single battery, but affects the life of the whole set of batteries. In practice, when the battery voltage is less than 32V, until 27V, the newly added continuation mileage is two or three kilometers, but the damage to the battery is very large.

Therefore, although the controller has undervoltage protection, it is best not to charge when it is. Proposal: For alert battery over-discharge, the undervoltage protection is preferably set between 0.5V-2V, this value is different, and the undervoltage protection of the nominal 24V is 21.

5V to 22V, regarding the nominal 36V Set 32V ~ 33V, should be set in 43V ~ 44V about nominal 48V. Such voltage reduction is only less than 2 km, but can effectively extend the battery life of the battery. } Do not use the car for a long time, it should be filled after it is filled, and the total switch is disconnected, and the battery will be added once every 1 to 2 months.

4, don't charge frequently. The charging time is too short. Some people are like this when using electric cars.

When they are not in use, they will be charged. When they use it, they will unplug the power, and no matter whether it is full (the truly perline should be 2-3 hours after the turning light. ) The battery life like this is very short.

5, charger factor. Check the various parameters of the charger, such as the highest charging voltage (the voltage of the constant pressure stage, is also called a constant voltage value), the constant voltage value is high, ensuring charging time, but sacrificed is lost water and vulcanization. The constant voltage value is low, the charging time and the charge are difficult to ensure.

The light current, too large or too small. Some charger manufacturers' products In order to reduce the indication of charging time, improve the current of constant voltage transfer floating charge, so that after the charging indicates that the overflow, there is no overall, rely on improving the floating charge voltage to make up for. This is still in a large amount of oxygen in the floating stage.

The oxygen circulation of the battery is not good, so it is also constantly exhausting in the floating stage. Control charging the highest charging voltage should be at 2.42V per grid (12V battery is 15.

2V per), that is, under the hydrogen supply potential. If it is charged in a state where the large current is charged at this time, the charging reception capability of the battery can be improved. Otherwise, once it is higher than the hydrogen, the battery will quickly lose water.
