Types, performance and battery maintenance of electric tricycle batteries

Types and performance of electric tricycle batteries:

1). Lead-acid batteries (including lead-acid gel batteries), which are cheap and stable in performance, and are used in electric vehicles on the market.

Brands include: Xu Pai, Dr., Tianneng, Chaowei, Haibao, etc. From the perspective of battery quality itself, it should be similar. The homogenization of such batteries is very serious, so buying such batteries is not the choice of the battery itself, quality, picking the quality of service.

At the same time, the battery pack size should be configured according to the power of the motor, and it should be configured according to the size of the battery box. Please pay attention to the above points when buying a new battery:

1. The battery identification should be clear, first, the date of production, and second, whether the capacity identification is consistent with or larger than the original battery.

2, it is recommended to weigh, the battery weight is a very important indicator, compared with the weight of the package identification, avoid exchange;

3, the battery open circuit battery, this is related to the production date;

4. When installing the battery, be sure to check it yourself, whether the welding or the screw is in place;

5. During the use, test whether the parameters of the charger match the battery. The general battery problem is caused by the charger mismatch.

Main models applied to three-wheel electric vehicle batteries:

EVF series (for tricycles) for electric road vehicles, the main types are:

6-EVF-32, 6-EVF-38, 6-EVF-45, 6-EVF-50.

Example of model naming rules:

6-EVF-45:

6- Represents the battery cell serial number, which is a 12V battery.

EVF-valve-controlled battery for electric road vehicles.

45-3 hour rate rated capacity value, 45Ah

2). Lithium-ion batteries (often referred to as lithium batteries) are expensive, unstable in performance, prone to explosion, and have a low safety factor. The lithium iron phosphate power battery currently being developed has solved the safety problem.

Battery maintenance

1. The battery cannot be stored in a loss of power. The state of deficient power means that the battery is not properly charged after it is used up. It is easy to cause salinization of sulfuric acid, so that the lead sulfate crystals adhere to the electrode plate of the battery, blocking the passage of the ion, which will cause If the charge does not charge, the battery capacity will drop. The longer the idle time in the deficient state, the more serious the battery damage. When the battery is not in use, it should be recharged once a month to extend the battery life.

2 The battery of the electric tricycle should be regularly inspected during use. If the mileage of the electric bicycle suddenly drops by more than ten kilometers in a short time, it is very likely that at least one battery in the battery group has a broken grid and a plate. Short-circuit phenomenon such as softening and falling off of active material of the electrode plate. At this time, you should go to the professional battery repair organization for inspection, repair or matching. .

3. Do not discharge the electric current bicycle. When starting, manning or going uphill, it is best to use the ankle to assist and avoid the instantaneous high current discharge. Large current discharges tend to cause lead sulfate to crystallize, thereby damaging the physical properties of the battery plates. . .

4. To master the charging time, under normal circumstances, the battery is charged at night, the average charging time is about 8 hours. If it is a shallow discharge (the mileage after charging is very short), the battery will soon be full. If it continues to charge, it will overcharge, causing the battery to lose water and heat, reducing battery life. Therefore, when the battery is discharged at a depth of 50%-60%, the charge is optimal. In actual use, it can be converted into a riding mileage, and the necessary charging is performed according to the actual situation to avoid harmful charging. .

5. To prevent high temperature exposure to electric vehicles, it is strictly forbidden to expose to sunlight. If the temperature is too high, the internal pressure of the battery will increase and the battery pressure limiting valve will be forced to open automatically. The direct consequence is to increase the water loss of the battery. The excessive water loss of the battery will inevitably lead to a decrease in battery activity, accelerate the softening of the plate, and charge the case. Fatal damage such as body heat, shell drumming, deformation, etc. maintenance

(1) Before riding, check if the battery box is locked and the display panel lights are normal.

(2) When driving on a stagnant water surface in rainy days, the water depth does not exceed the normal driving of the center of the electric wheel. If the water depth of the road surface exceeds the center of the electric wheel, it may cause the electric wheel to seep and cause a malfunction.

(3) The whole vehicle should be placed in a place where the air is humid, the temperature is too high and corrosive gas is present, so as to avoid chemical corrosion of the electroplated paint surface of the metal parts.

(4) It should be avoided that the whole vehicle will be exposed to the sun for a long time and rain, so as to avoid damage to the components inside the controller, resulting in malfunction and accidents.

(5) The electrical control part has a complicated structure, and the user should not disassemble or repair it without authorization. If the local charging voltage is unstable, it is easy to blow the charger fuse. It is recommended to use an AC voltage regulator.

(6) The electric bicycle feels heavier when it is reversing, and it is normal to have a slight friction sound in the forward propulsion hub.

(7) Cycling should not be overloaded. Heavy objects and people should not be placed to avoid damage to the battery and motor.

(8) Lubrication of electric vehicles is an important part of the maintenance of electric vehicles. According to the use situation, the front axle, rear axle, central axle, flywheel, fork, shock absorber pivot point and other components should be scrubbed every six months to one year. Lubrication (Molybdenum disulfide grease is recommended). The transmission components in the electric hub have been coated with special lubricants, so users do not have to scrub the lubrication themselves. If abnormal conditions are found, you can go to the special maintenance point for maintenance.
