The most taboo thing about lead-acid batteries is to charge them after being discharged cleanly. In this case, the battery life will be significantly reduced. Power outages, Undervoltage and power outages must not continue to power on and drive, and the intermittent discharge of electric vehicle batteries will hurt the battery the most. If you encounter an electric vehicle Undervoltage and power failure during driving, it is best to get off the vehicle, close the electric door lock, and push the car to drive. Hope to help you!

1. Charge when the battery indicator shows one-third of the remaining battery.

2. The charging environment should be kept dry and tidy, and the charger should not be wrapped in plastic bags or plastic bottles because it is straightforward to burn when the charger cannot breathe.

3. Try not to use fast charging. If not necessary, do not use it more than twice within a month.

4. The charger is placed in a fixed place, do not bump it. Even if carried, it must fully consider the bumps that cause failures.

5. Use the standard charger to charge.

1. The ideal charging time is when 60% to 80% of the battery is consumed.

2. Diligently use and recharge.

friendly reminder:

1. Lead-acid batteries have no time and charge requirements for initial charging and can be charged and discharged without causing plate memory.

2. It should be noted that over-discharging and over-charging are not allowed. Over-charging is the process of turning into a workshop, which will cause the metal layer of the grid to become thinner and easily break the grid. To shorten the life of the plate, lead-acid batteries should pay attention to the specific gravity and liquid level of the electrolyte and not lack of liquid.

3. When the lead-acid battery is used in the car, it is charging and discharging at any time. The battery meter on the old Jiefang truck is an ammeter with a pointer. You can see whether it is charging or discharging, especially the headlights. When the high beams are fully turned on, the generator's power supply is insufficient. When decelerating, the generator speed is low, calling some of the electricity in the battery. Therefore, charging and discharging will automatically switch dozens of times every night. The battery must be fully charged. ,

The battery/battery is the power source of the electric bicycle, and it is also a consumable item, and the price is high. Therefore, keeping the battery in good working condition and prolonging its service life significantly impacts environmental protection and the economy. Practical value. Here are some maintenance methods for batteries:

1 Newly purchased electric vehicle should be fully charged before use. Because many electric cars have been shelved in stores for several months, or even more than half a year, they must be fully charged before using them.

2. Take off the battery for charging. When installing, the battery should be firmly established on the electric bicycle to prevent the battery from being damaged by vibration during riding. When the battery is being transported, it is forbidden to drop, roll, or press it.

3. Always remove the dust and dirt on the battery cover, and pay attention to keeping the battery dry and clean to prevent the battery from self-discharging.

4. The battery must not be left in a state of insufficient power for a long time, and it is necessary to develop a good habit of charging the battery every night. It is not required temporarily. It should be fully arrested, placed in a cool and dry place, and charged regularly (usually ten days)

5. When the electric bicycle is just started, use the pedal (the way without the pedal can push the ground with the foot) to assist in creating, and when going uphill, use the pedal to help the electric bicycle go up the slope, so as to avoid excessive discharge current and damage the battery.

6 When riding, be careful not to over-discharge the battery. After the battery is discharged to the termination voltage, it is called over-discharge if it continues to release. Over-discharge can easily lead to profound battery loss, thus significantly shortening its service life. Therefore, the battery should be used to avoid deep discharge as much as possible so that shallow release and frequent charging should be achieved. In general, the battery should be charged once when the discharge depth is 50%.

Electric bicycles are generally equipped with an Undervoltage protection function. When only one indicator light of the battery level indicator is on, the power should be turned off, the pedal should be used, and the battery should be charged as quickly as possible to avoid over-discharge of the storm.

When the battery is discharged to the terminal voltage, the internal resistance is significant, and the electrolyte concentration is fragile, especially the inside and surface of the plate hole are almost neutral. When over-discharged, the internal resistance has a tendency to generate heat, and the volume expands. When the discharge current is large, it will generate apparent heat. Even heat deformation occurs. At this time, the concentration of lead sulphate is enormous, and the possibility of short-circuiting of crystalline branches increases. Moreover, lead sulphate will crystallize into larger particles at this time. That is, irreversible sulfation will be formed, which will further increase the internal resistance and charge recovery. The ability is so poor that it cannot even be repaired.

When the battery is used, it should prevent over-discharge and take adequate measures of "under-voltage protection." In addition, because the "Undervoltage protection" of electric vehicles is controlled by the controller, some other equipment other than the controller, such as voltmeters, indicators and other power-consuming appliances, are directly powered by the battery and the power supply is generally not controlled by the controller. Electricity is used as soon as the electric vehicle lock switch is closed. Although the current is small, if it is discharged for a long time, for 1-2 weeks, over-discharge will occur. Therefore, the lock should not be opened for a long time, and it should be turned off immediately when not in use.

7. Prevent overcharging, stop charging when the charger shows full, can not be changed overnight or even days. Overcharging will cause the active material of the plate to harden and fall off, resulting in water loss and battery deformation. The battery runs in the high-temperature season, and there is mainly the problem of overcharging. Therefore, in summer, the temperature of the battery should be reduced as much as possible to ensure good heat dissipation, prevent charging after exposure to the sun, and keep away from heat sources.

To prevent overcharging, in addition, the parameters of the charger should be well-matched with the battery, and the operating conditions of the battery in the high-temperature season should be fully understood, as well as the changes during the entire service life. Please do not place the battery in an overheated environment during use, especially when charging. Keep it away from heat sources. After the battery is heated, take cooling measures, and the battery can be captured when the battery temperature returns to normal. The installation position of the battery should ensure good heat dissipation as much as possible, stop charging when it is found to be overheated, and check the charger and battery. When the depth of discharge of the battery is shallow, or the ambient temperature is high, the charging time should be shortened.

8. To prevent temporary power loss, the temporary power loss will make the plate vulcanized. In the case of low temperature, the charging mainly has the problem of poor charging acceptance and lack of charging, which causes the battery to lose power. At low temperatures, heat preservation and antifreeze measures should be taken; especially when charging, it should be placed in a warm environment, which is conducive to ensuring sufficient power, preventing the occurrence of irreversible sulfation, and prolonging the service life of the battery.

9. To prevent short circuits, special care should be taken when installing or using them. The tools used should be insulated. When connecting, the electrical appliances other than the battery should be connected first. After inspection, there is no short circuit. Finally, click the battery. The wiring specifications should be well insulated to prevent overlapping. Cracked under pressure. It is forbidden to use the method of battery short circuit to detect the charged condition of the battery so as to prevent the explosion and cause casualties

When the battery is in a short-circuit state, its short-circuit current can reach hundreds of amperes. The stronger the short-circuit contact, the greater the short-circuit current, so all the connections will generate a lot of heat, and the thin links will generate more heat, which will fuse the relationship and cause a short circuit. Explosive gas may occur locally in the battery or the combustible gas accumulated during charging. When the connection is connected, sparks may be generated, which will cause the battery to explode; if the battery is short-circuited or the current is not particularly large, the connection may not be blown. But the short circuit will still cause overheating, which will damage the adhesive around the connecting strip, leaving hidden dangers such as leakage. Therefore, the battery must not be short-circuited. Special care should be taken when installing or using it. The tools used should be insulated. When connecting, the electrical appliances other than the battery should be connected first. After inspection, there is no short circuit. Finally, click the battery. The wiring specification should be Good insulation to prevent cracks caused by overlapping pressure.

10. Prevent the battery from discharging with a high current for a long time, which will significantly damage the internal structure of the battery. It is recommended that the owner should not start more than 5 seconds each time. Two consecutive starts are required, with an interval of 1015 seconds in between.

11. Avoid exposure to sunlight, which will increase the temperature of the battery, increase the activity of each active substance in the battery, and affect the service life of the battery.

12 The discharged battery should be recharged in time and should not be put on hold for more than 12 hours.
