1. Electric vehicle battery repair methods:
(1) High voltage charging and deep discharge repair method (applicable to batteries with reduced range of 1/2 in electric vehicles) A. Charge the 48V battery with a 60V charger for 8 hours. B. Discharge the battery to 0V (no power at all) with a light bulb or heating element. Discharge separately or in parallel.
(2) Battery reconfiguration method (applicable to batteries in electric vehicles with a range reduced by more than 1/2 or bulging):
A. Select the bulging battery and exchange it for an older one. The replacement battery has a load voltage of 11.4V-12.7V and a terminal voltage of around 13.2V. B. Drive the electric scooter until it can no longer run, then prop it up and let it idle. Use a multimeter to measure the voltage of each battery. Select the battery with the lowest voltage and exchange it for an older one. The replacement battery has a load voltage of 11.4V-12.7V and a terminal voltage of around 13.2V.
(3) It is best to add Little Coppersmith Battery Repair Fluid for the above operations, as this will have a significant effect.
2. Electric vehicle battery maintenance methods:
(1) Adding distilled water: A. When the electric vehicle battery has been used for 6 months. B. When the electric vehicle's range begins to decrease.
(2) Adding Xiaotongjiang nano carbon sol battery activator: A. When the electric vehicle is unable to go uphill and the range is reduced by 1/3. B. When the electric vehicle battery has been used for about a year.
(3) Keep the battery fully charged. Every day when riding an electric bicycle, whether it is 10-15km, you should recharge it to keep the battery in a "fully charged" state. Also, charge it on the same day. If you leave it idle for a few days after use and then recharge it, it is easy to cause extreme sulfation and capacity reduction.
(4) Do not store batteries when they are low on power: storing batteries when they are low on power will seriously affect their service life. If the battery is left idle for a long time, the damage will be more severe.
(5) Charge the battery whenever you need it: When charging, the indicator light on the charger will turn red first and then green. After the light turns green, you should float charge for 2 hours, which is beneficial to suppress battery sulfation.
(6) Prevent battery overcharging: Overcharging the battery generates a large amount of gas that washes over the plates, accelerating the shedding of active materials from the plates and shortening the battery life. Overcharging the battery accelerates water loss, causing the electrolyte to dry out, the battery temperature to rise, resulting in thermal runaway, plate expansion, and casing deformation.
Electric vehicle battery repair methods: What if your electric vehicle's range is reduced by 1/2 or less due to improper battery maintenance? Follow these tips to repair the battery yourself and restore it to like-new condition, extending its lifespan by more than a year.
(1) High-voltage charging and deep discharge repair method: (Applicable to batteries whose range of electric vehicles has been reduced by 1/2)
A can be charged to a 48V battery in 8 hours using a 60V charger.
B. Discharge the battery to 0V (without any power) using a light bulb or heating element. Discharge the battery individually or in parallel.
(2) Battery reconfiguration method: (Applicable to batteries in electric vehicles with a range reduced by more than 1/2 or bulging)
Select the bulging battery and exchange it for another. The replacement battery has a load voltage of 11.4V-12.7V and a terminal voltage of around 13.2V.
B drove the electric scooter until it could no longer run, then set it up and spun it idle. Using a multimeter, B measured the voltage of each battery and selected the one with the lowest voltage. The old battery was then exchanged for the new one. The new battery had a load voltage of 11.4V-12.7V and a terminal voltage of around 13.2V.

2. Electric vehicle battery maintenance methods: (1) Add distilled water: A. When the electric vehicle battery has been used for 6 months. B. When the electric vehicle's range begins to decrease. (2) Add Xiaotongjiang nano carbon sol battery activator: A. When the electric vehicle is weak uphill and the range is reduced by 1/3. B. When the electric vehicle battery has been used for about one year.
(3) Keep the battery fully charged. Every day when riding an electric bicycle, whether it is 10-15km, you should recharge it to keep the battery in a "fully charged" state. Also, charge it on the same day. If you leave it idle for a few days after use and then recharge it, it is easy to cause extreme sulfation and capacity reduction.

1. Keep the battery fully charged. Every day when riding an electric bicycle, whether it is 10-15km, you should recharge it to keep the battery in a "fully charged" state. Also, charge it on the same day. If you leave it idle for a few days after use and then charge it, it is easy to cause sulfation and capacity reduction.
2. Perform regular deep discharge: It is recommended that you perform a deep discharge once every two months, that is, ride a long distance until the low voltage indicator flashes. This will deplete the battery and allow you to understand its current capacity level and whether maintenance is needed.
3. Do not store batteries when they are low on power: Storing batteries when they are low on power will seriously affect their service life. The longer the battery is left idle, the more serious the damage will be.
4. Regular checks: If your new car has a range of 50km and experiences a significant reduction in range within three months, such as only a few kilometers, you can use a multimeter to check the voltage at the battery's external terminals. A fully charged battery should normally have 39-42 volts. If it's several volts lower, or if one battery in the battery compartment has a voltage below 10.5 volts, it may indicate an internal short circuit. In this case, you should take it to a repair shop for repair or replacement to avoid damaging the other two good batteries. Also, check the charger for malfunctions.
5. The electric vehicle is designed to carry a load of 75kg, so avoid carrying excessively heavy items. Use your feet to assist when starting and going uphill. This is because the motor current increases at these times, causing the battery to discharge too quickly and the voltage to drop rapidly. The lower the discharge rate of the battery each time it is used, the longer the capacitor's lifespan. Therefore, reducing high-current discharge can extend battery life and increase driving range. Furthermore, regardless of the battery capacity, users should develop the good habit of charging the battery whenever needed.
6. It is normal for battery capacity to decrease as the temperature drops in winter. With 25℃ as the standard, the capacity is generally 80% at -10℃.
7. Keep the battery surface clean for a long time. Do not expose the vehicle to direct sunlight when parking. Instead, park the vehicle in a cool, ventilated and dry place.
8. When using the charger, try to use the original charger to avoid short circuits caused by reversed output voltage, which can burn out the charger and severely affect battery life. It is recommended to use a smart charger that can adjust the constant voltage value according to the ambient temperature.
9. Braking and restarting an electric vehicle while it is in motion will damage the battery and affect its range, so avoid frequent braking and starting.
10. The widespread use of electronic horns consumes a lot of power and is very damaging to batteries. It is recommended to avoid frequent use as much as possible.
11. In hot summer weather, charging should be done in a cool, well-ventilated place. Ideally, charge for 2-3 hours, then wait 1 hour before charging again. In cold winter weather, try to charge indoors.
