How long will it take to charge the lithium battery of electric vehicle?

1, after buying a car (or changing the battery), the battery should have about 80% of the power, home should be charged, the time is to change the charger lights and then charge 4 hours is appropriate, so to three times.

2. Keep charging every day (36v has ridden 10km, 48v has ridden 15km), but the charging time should not be too long, one hour after the charger changes the light is appropriate. When charging, would rather undercharge a few, also do not want overcharge, otherwise battery can be charged because lack of water hind, baggy, swollen. Cause irreparable damage to the battery.

3, do not let water into the battery box, in order to cause the battery in the shell power.

4. Fully discharge once a month (ride until "under-voltage" light turns on), and then charge continuously for 12 hours.

5, conditional of battery pack in the monomer switch, over the warranty period of the battery (especially in the summer), every three or four months to each monomer of the battery to supplement 3-4 ml of deionized water (Wahaha pure water can also like this).

6, once found that the charger does not turn the green light or turn the green light as soon as charging, be sure to check whether there is something wrong with the charger, or water loss.

7. The discharge port and charging port of the whole group of batteries should be kept clean at any time to prevent copper rust at the contact point, causing overheating and damage due to poor contact.

8, have feet as far as possible to start with feet, do not load too much, speed gently. Don't get on the bus and start it up with electricity.

A set of batteries can be used for more than 5 years under correct charging and normal maintenance. Many users only use 1-2 years to replace, mainly due to improper charging, so it is important to master the correct charging method. Remember the battery isn't broken, it's broken.

1. The charging time of the first charge, because the battery car battery is not used in the factory, has not experienced charging and discharging, to ensure the normal operation of the battery. In general, the charging time can be controlled within 5-6 hours, so that the battery can be fully charged, and then the application can be slightly longer.

2, after the first charge, although not charging for the first time, but the second is new car charge, then you can make a storage battery power is about to run out of time, and then for a long time of charging, the charging can maintain 8-9 or 10 hours, in order to make storage battery chemistry to make a complete cycle.

3, the battery car charging for the first time, the charger may generate heat quickly, heat is very high, therefore, especially in the summer when charging, the charger should not be placed on objects easy to burn heat, it is best not to put on the seat of the battery car, to prevent fire.

4. Before the first charge, the electric vehicle needs to run out of electricity, but it cannot run out. Electric cars won't be too full when they're new, but they won't be too low, unless they're old or shoddy. When you use it, you should estimate the distance you can run according to the merchant's estimation, so as not to run out of power or run out of power. When the battery car power display has reached the last grid, it is necessary to consider not riding, to be ready to charge.

Recharge your batteries every day

Even though your electric car's lithium battery can last two to three days on a single charge, it is recommended that you charge it every day. Since the lithium battery after use is in a shallow cycle state, charging every day will prolong the life of the lithium battery of electric vehicles.

2. Timely charging

Because lithium batteries in the discharge, will enter the vulcanization process, if timely charging, you can remove the serious vulcanization. Therefore, lithium battery should be charged as soon as possible after the use of the battery, as far as possible to make the battery power in a full state.

3. Regular deep discharge

A regular deep discharge of the battery also helps "activate" the battery, slightly increasing its capacity. The usual method is to discharge the battery completely at regular intervals.

The method of full discharge is to cycle to the first under-voltage protection under normal load conditions on a flat road surface.

After the battery is under voltage protection for the first time, after a period of time, the battery will return to the state of non-under voltage when the battery is fully charged, which will improve the capacity of the battery.

It should be noted that the lithium battery in the first under-voltage protection, remember not to use the battery, at this time the damage to the lithium battery is very big.

4. Try to use the original charger

Generally, charger of each manufacturer has personalized demand generally, do not change charger at will when in doubt. In addition, do not remove the speed limit of the controller, remove the speed limit of the controller, although it can improve the speed of some cars, but it will reduce the service life of the battery.

In fact, the correct use of lithium batteries in electric vehicles, but also with a lot of small make up will not be tired of this one. When you buy an electric car, there are generally instructions. In order to your electric car lithium battery can live a long time, small make up in remind you of a sentence, must be in accordance with the correct use of electric car lithium battery method to implement, must not give lithium battery overcharge or over discharge.

Each charge should be 40-60% of the time when the most reasonable charge, charging time 12AH battery 5-8 hours, 17-20ah battery 8-12 hours, the size cannot exceed 12 hours, the first time as usual, nothing to say... Don't charge it 2-3 times a month for a long time.
