Electric car battery

How to charge the new electric car for the first time?

Everyone should understand the importance of correct charging and discharging of the battery for the first time. There are still some misunderstandings about charging the new car. For example, the first charging should be full of 24 hours, and the power must be exhausted before charging. Is this the case? So how do you charge the sciences below?

Electric vehicle charging

1. Before the first charge, the battery will run out but not enough. When the electric car display has reached the last grid, it is ready to be charged.

2. Choose to be more assured during the day, so that the battery will not be overcharged and discharged for the first time, it is easier to make the first chemical reaction in the battery normal.

3. The first charging time is 5-6 hours, so that the battery can be fully charged, and then it can be charged for a little longer.

4. The second charge can be charged for a long time, 8-9 or even 10 hours, in order to let the battery car chemical reaction for a complete cycle.

5. When the battery car is first charged, the charger may generate heat quickly and the heat is very high. Therefore, the charger should not be placed on objects that are prone to heat and burn to prevent fire!

Daily electric car battery charging maintenance tips

1, the charger should be matched, try to use the matching charger when charging.

2. Under normal circumstances, fully charge the battery. After the charger turns on the light for about 1 hour, you can stop charging. It is best if the charger does not exceed 2 hours after turning the light.

3, usually charge to do "diligent charge shallow", that is, after each use, conditional charging, do not use undervoltage and recharge at a time, each time the rechargeable battery is full.

4, the master's experience, it is best to do every 7 to 15 times after charging, do a full charge, this will help improve the battery capacity and extend the life of the battery. (Hint: Do not use this method if it is not used, otherwise it will be prone to adverse consequences.)

The best way to do it: After the first indication of power failure, the electric vehicle battery has undervoltage protection. For the standard 36V electric bicycle, the undervoltage protection voltage of most controllers is around 33V. Will slowly return to the power supply, at this time do not ride electricity, otherwise the battery over-discharge will affect the battery life. It will be enough to charge (full charge) after the first power outage.

5, in the process of using electric vehicles, you can help a lot, the battery is provided as the final effect, it should be the main force of help, if forced to start using and bring people, I am afraid that the power consumption situation or damage to the battery is not only 1 The relationship of multiples.

The importance of electric vehicle battery management system

Electric vehicle battery management system

Nowadays, many people who use electric vehicles have the same feeling: the battery is not durable, it will be scrapped in a year or so, and charging is also done according to the above method. Why is the battery still not used for a long time?

Although we can do the above method when charging, there are some invisible indicators that we don't know very well. For example: voltage, current, temperature, we can't grasp, and we can't know, like the overvoltage of lithium batteries in electric vehicles. Or it is easy to scrap after the undervoltage. In life, we can't always pay attention to the battery condition of the electric car.

The lithium battery protection system can measure the lithium battery voltage well, and then judge whether the lithium battery is in a normal state (non-overvoltage, non-undervoltage) according to the voltage and voltage. When the battery has overvoltage/undervoltage/overcurrent/overtemperature/short circuit, etc., it can be adjusted in time to prevent the battery from being unfavorable to the battery charging, and also to avoid the spontaneous combustion explosion of the battery! The electric vehicle class is better. The lithium battery management system is a digital lithium dog system. It not only ensures the battery charge and discharge safety, but also has a strong anti-theft function!

Well, today's electric car battery charging skills we say so much, I hope to help everyone!
