Analysis of the correct charging and maintenance of lead-acid batteries for electric vehicles

1. Charge when the battery indicator shows the remaining one-third of the 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 the charger is easily burned when it is not breathable. 3. Try not to use fast charging, if not necessary, no more than twice in a month. 4. Place the charger in a fixed place, don't bump it, even if you carry it, you must fully consider the malfunction caused by bumps. 5. Use the standard charger to charge. 1. The most ideal charging time is when 60% to 80% of the battery's power is consumed. 2. Use and charge frequently. 1. Lead-acid batteries have no time and amount of charge for the first charge, and they can be charged and discharged at any time without causing plate memory. 2. It should be noted that over-discharge and over-charge are absolutely not allowed. Over-charging is a process in the chemical workshop, which will cause the grid metal layer to become thinner and easily break the grid. Excessive discharge will cause the electrode plate to vulcanize and the active sponge structure to fail. To shorten the life of the plate, lead-acid batteries should pay attention to the specific gravity of the electrolyte and the height of the liquid level, and there should be no shortage of liquid. 3. When lead-acid batteries are used in cars, they are charged and discharged at any time. The battery meter on the old Jiefang truck is a pointer ammeter, and you can see whether it is charging or discharging at any time, especially the headlights. When the high beam is fully turned on, the power supply of the generator is insufficient, and the speed of the generator is low when decelerating, which means that part of the battery is used. Therefore, charging and discharging will automatically switch dozens of times every night, no effect, no need to be like NiMH The battery must be overflowing like that. 、Battery/battery is the power source of electric bicycle, it is also a kind of consumable, and the price is relatively high, so keep the battery in good working condition and prolong its service life, no matter from the environmental protection or economic point of view, it has great The practical value. The following are some maintenance methods for the battery: 1 The newly purchased electric vehicle should be fully charged before using it. Because many electric vehicles have been stored in stores for several months, or even more than half a year, they must be fully charged before using them. It is best not to use them immediately after they are fully charged. They need to be left for about ten minutes. 2 Remove the battery for charging. When installing, install the battery on the electric bicycle firmly to prevent the battery from being damaged by vibration during riding. Do not drop, roll over, or press the battery during transportation. 3 Always remove the dust and dirt on the battery cover, pay attention to keep the battery dry and clean to prevent the battery from discharging by itself. 4 Never leave the battery in a state of insufficient power for a long time, and develop a good habit of charging the battery every night. Temporarily unnecessary, it should be charged, placed in a cool and dry place, and charged regularly (usually 10 days) 5 When the electric bicycle is just started, use the pedal (you can use the foot to push the ground without a pedal) to assist in starting, and when going uphill , Use the pedal to help the electric vehicle go uphill, so as not to damage the battery due to excessive discharge current. When riding, be careful not to over-discharge the battery. After the battery is discharged to the termination voltage, continuous discharge is called over-discharge. Over-discharge can easily cause serious power loss of the battery, thereby greatly shortening its service life. Therefore, when the battery is in use, beware of deep discharge as much as possible, and perform shallow discharge and frequent charging. Generally, it is best to charge the battery once when the depth of discharge is 50%. Electric bicycles are generally equipped with undervoltage protection. When only one indicator light on 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 battery.
