How to connect the battery of electric vehicle

1. Do not change the charger casually and do not remove the speed limit of the controller

The charger of each manufacturer has personalized demand commonly, do not change charger at will when uncertain. If the mileage requirement is long, it must be equipped with multiple chargers for off-site charging. The charger that is fully charged during the day should be used with a supplementary charger, and the original charger should be used at night. Removing the speed limit from the controller may increase the speed of some cars, but it will not only reduce the safety of the car, but also reduce the battery life.

2. Protect the charger

The general operating instructions have instructions on how to protect the charger. Many users do not read the manual habit, often in addition to the problem later think of looking for the manual, often too late, so it is very necessary to read the manual. In order to reduce the cost, the current charger is basically not done high vibration design, so that the charger generally do not put in the trunk of the electric bicycle and the basket. If it is necessary to move, the charger should be packed with foam plastic to prevent vibration. After the vibration of many chargers, their internal potentiometer will drift, making the whole parameter drift, resulting in abnormal charging state. In addition, it is necessary to keep the charger ventilated when charging, otherwise it will not only affect the life of the charger, but also affect the charging state due to thermal drift. This will damage the battery. Therefore, it is very important to protect the charger.

Recharge your batteries every day

Even if your endurance is not long, you can use it for 2 to 3 days with a single charge, but it is still recommended that you charge it every day, so that the battery will be in a shallow cycle, and the battery life will be extended. Some early users of mobile phones thought that it was best to charge the batteries after they were basically used up, which was wrong. The memory benefits of lead-acid batteries were not as strong. Frequent discharge of the battery life of the impact is relatively large. After most chargers are fully charged when the indicator light changes, the battery charge may be 97% ~ 99%. Although the power of undercharge is only 1% ~ 3%, the impact on the range can be almost ignored, but it will also form the accumulation of undercharge, so after the battery is fully charged, the lamp will continue to float charge as much as possible, which is also good for suppressing battery vulcanization.

4. Timely charging

After the battery discharged, the vulcanization process began, and at the beginning of 12 hours, there was a significant vulcanization. Timely charging, can remove the serious sulfide, if not timely charging, these sulfide crystals will accumulate and gradually form large crystals, the general charger is powerless to these large crystals, will gradually form the decline of battery capacity, shorten the service life of the battery. Therefore, in addition to charging every day, you should also pay attention to charging as soon as possible after using, so as to make the battery power in full state.

5. 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 cycling under normal load conditions on flat surfaces to the first under voltage protection. Note that we place special emphasis on the first under voltage protection. After the battery is under voltage protection for the first time, after a period of time, the voltage will rise and return to the non-under voltage state. At this time, if the battery is used again, it will do great harm to the battery. After a complete discharge, the battery is fully charged. Will feel the battery capacity has increased.

6, develop some good habits of power saving

Use taxiing whenever possible. For example, when going downhill, take advantage of the power cut ahead of time to slow down. Slide in ahead of the traffic light to minimize braking. A friend of mine told me that he would rather make one more turn than one brake, and it made sense

When starting, it is best to add riding power, which can not only improve the starting speed, but also reduce the loss of battery power and life damage.

7. Pay attention to the charging environment

Charging the best environment temperature is 25 ℃. Now most of the charger did not adapt to the environment temperature automatic control system, so most of the charger is designed according to the environmental temperature 25 ℃, so in 25 ℃ under the condition of charging is better. Otherwise, it is hard to avoid the problem of under-charging in winter and over-charging in summer. And ambient temperature at 25 ℃ real time is less, so it must be summer winter owe battery problem. Fortunately, most families now have indoor temperature regulation conditions, so, when charging, it is best to arrange the battery and charger in a ventilated and temperature regulation environment.

In particular, the battery in the northern winter in the low temperature outside into the warm indoor state, the battery surface will appear frost condensation. In order to avoid battery leakage caused by frosting and condensation, the battery should be charged after the battery temperature rises close to the indoor temperature and dries out.

8. Make full use of the maintenance conditions

Many e-bike dealers can provide battery repair and maintenance services, should make full use of these services. Some brands of e-bikes have proposed battery overhauls. For example, regular maintenance of the battery can reduce the damage to the battery. Fixing the battery's charged state can mitigate "battery lag" failures, which are easy for dealers equipped with maintenance capabilities. For water loss, rehydration at 70 percent of the battery capacity is better than rehydration at 40 percent of the battery capacity. Even some brands suggest that failure to repair within the required time is equivalent to giving up the battery warranty. Make consumer suffer the loss that should not happen. Therefore, consumers should make full use of the condition of battery maintenance to extend the service life of the battery.

The red of the battery pole note is a positive pole, black is a negative pole, the battery is in series in the battery box, that is to say, the positive pole of a battery is connected to the negative pole of another battery, according to this connection method, the last will be left with a positive and a negative two lead, connect the battery discharge port.

Connect two car positive pole first, connect negative pole later, this order is to prevent careless take iron short circuit. When the negative terminal is connected, there are many cars whose negative terminal posts are blocked by other parts and cannot be connected.

You can find any metal part on the body of the car, because the whole body is equivalent to the negative electrode of the battery. The important thing is not to get it wrong.

Connecting the positive and negative terminals will cause the engine computer and other components to burn down, because it is equivalent to two batteries in series and the voltage is too high. When knocking down the battery line on fire, first pull down the negative pole, and then pull down the positive pole.

Many people, especially older cars, have experienced a situation where the battery is dead and they can't start. Battery power has the following reasons, the first is the battery life, storage power greatly reduced, so the car put a night do not open can not start; Secondly, the vehicle is placed for a long time do not open, natural discharge and lead to loss of electricity; Still have a kind of circumstance is to forget to close use electricity the equipment is caused by, or the vehicle has breakdown, have leakage of electricity, bring about put very short time to be able to lose power.

So once the battery power failure can not fire, generally is to call for rescue or find their own car with electricity. Call rescue save worry, do not need oneself to operate, drawback is the time that should wait commonly is longer, also collect fees likely. If you can take electricity, will save a lot of time, so how to operate electricity?

You'll also need a car with electricity, or an emergency power supply. Next, get the cars close enough that the battery lines can reach both cars' batteries, either head-to-head or side-by-side. Then connect the battery line, the formula is the positive pole is connected to the positive pole, the negative pole is connected to the negative pole.
