The so-called battery is an electrical chemical device that stores chemical energy and discharges electric energy when necessary. Generally referred to as a battery. After the battery is discharged, the internal active material can be regenerated by charging - storing electrical energy as chemical energy; and converting the chemical energy into electrical energy when discharging is required. Let's take a look at the daily charging method of the electric tricycle battery. How to maintain the electric tricycle battery?

Electric tricycle battery charging method

Electric tricycle batteries are generally tubular traction lead-acid batteries. The model number is X XV-×XAh, such as l2V--120Ah. The front section indicates the nominal DC voltage of the lead-acid battery, and the latter section indicates the nominal capacity of the lead-acid battery. Before using the lead-acid battery, a sulfuric acid electrolyte having a density of 1.289/cm3 should be injected into the six cells of the battery. The electrolyte should be kept between the maximum and minimum liquid level of the battery. After the dry-charged battery is filled with the electrolyte for 30 minutes, the battery can be used for loading. Charging with a three-stage charger for more than 12 hours before use is beneficial for extending battery life.

1. New car charging method

It is best to use the new car first after charging. The method is to adjust the charging current to within 14A and charge for more than l5h. The first 5 to 10 times of charging time should be as long as possible, so that the permeability of the battery plate can be fully reacted, which is beneficial to improving the mileage of the whole vehicle and prolonging the service life of the battery.

2. Do you need to charge every day?

According to the user's usage habits, they are generally used during the day and charged at night. The electric tricycle can drive 80-120km with sufficient power, and the design life of the battery is more than 700 times of charging and discharging (two years).

(1) If the mileage is sufficient, it is recommended to charge only once a day.

(2) If it is not enough, you can recharge it once at noon.

(3) The state of depletion should be charged for more than 8 hours. If the electricity is not used up (less than 50km in summer and less than 30km in winter), the charging time can be shortened depending on the actual driving mileage. Experience has proved that it is generally 1h or 20km and needs to be charged for 2 hours.

(4) If you drive within less than 2 km per day, you can charge the battery for 2 days, and the charging time is more than 2 hours. Use it for a long time, and conduct a deep charge (10h or more) every 10 days.

3. charger

The charger should clean the dust on the cooling fan inside the machine after charging, which is essential to extend the service life of the charger.

4. Electric tricycle charger performance parameters input voltage: AC 220V +5%, 50Hz.

Output voltage: DC 24V, 36V, 48V, 60V, 72V (lead acid battery pack). Charging current: 0 ~ 20A.

Working environment: a 5 ° C ~ "O ° C, no flammable and explosive gases, no corrosive gases, ventilation and dry places.

Insulation resistance: ≥ l0MQ.

Maintenance of electric tricycle battery

Electric vehicles, like electric tricycles, are all lead-acid batteries.

Use and maintenance of electric vehicle battery

Lead-acid batteries are the main batteries used in electric vehicles. The batteries are not worn out but are damaged. It is by no means an alarmist. The battery charging performance plays an important role in the service life and performance of the battery.

1. The discharge depth of the battery has a great influence on the cycle life of the battery. This is because the deeper the depth of discharge, the larger the amount of expansion and contraction of the electrode, and the more the active material of the positive electrode falls off, thus losing the discharge characteristics and degrading the performance until the end of life. Therefore, the battery should be used to avoid deep discharge as much as possible, so as to be shallow and diligent, the general situation should be: the battery is best charged with a discharge depth of 50%-70%.

2. After the battery is discharged to the termination voltage, continuous discharge (overdischarge) will seriously damage the battery. This is because irreversible sulfation is easily formed at this time, which makes the charge recovery ability worse or even impossible to repair. Therefore, the battery should be protected from overdischarge when used. "Undervoltage protection" is an effective measure. The “undervoltage protection” measure is controlled by the electric vehicle controller. However, since the electric appliances such as the electric vehicle instrument and indicator light are not controlled by the controller, the electric vehicle lock starts to use electricity once it is closed, although the current is small, If it is discharged for a long time, the battery will be over-discharged. Therefore, it is not allowed to unlock for a long time, and should be turned off immediately when not in use.

3. The charging current should be less than or equal to the charging current that the battery can accept. Otherwise, the excess current generated by overcharging will cause the electrolyzed water to be consumed too quickly, and a serious gassing phenomenon will occur, which will make the charging become longer. It is very difficult, so it is possible to prevent overcharging as much as possible during charging. Chargers made by regular manufacturers ensure that the battery is not overcharged.

4. Lead-acid batteries are especially afraid of loss of electricity and discharge. If the battery is placed for 3-7 days, it will be permanently damaged. Therefore, please charge the battery as soon as possible after using it. For batteries that are not used for a long time, charge the battery once every 15 days to compensate for the loss of self-discharge when the battery is stored.

5, the battery runs in the hot season, there is mainly the problem of overcharging. Therefore, in summer, the battery temperature should be reduced as much as possible to ensure good heat dissipation, to prevent charging after sun exposure, and to stay away from heat. In the case of low temperature, charging mainly suffers from poor charging acceptance and insufficient charging to cause the battery to lose power. In case of low temperature, anti-freezing measures should be taken, especially when charging, it should be placed in a warm environment, which is beneficial to ensure sufficient electricity, prevent irreversible sulfation, and prolong the service life of the battery.

6. Under normal circumstances, the service life of a battery with a large depth of discharge is about 1 year, and the life of a battery with a depth of 50%-70% is about 1 year and a half.
