Does that manufacturer produce fast charging electric vehicle batteries?

If the battery breaks after 5-6 times at the charging station, the problem is not in the battery but at the charging station.

Lead-acid batteries and lithium batteries have worse performance than fast charging, and general fast charging can only charge to about 70%.

Generally speaking, most of the batteries can be charged at 1C using positive and negative pulse technology, which means that all qualified batteries are fast charging bottles, and there is no need to develop special batteries for fast charging.

Whether fast charging is harmful to the life of the battery, there is no special research in China, from practical experience, even if there is a loss of battery life, this loss is very small, and fast charging is often only for emergency use, all of which are not very damaging to the battery.

It is very unrealistic, and a fast charging station can be charged for 1 yuan for 10 minutes. If you charge up to 3 yuan, you can run 5-7 kilometers once (10 minutes). We can calculate the account, according to the normal charge of a battery can run 40 kilometers, every day to use fast charging is about 180 yuan a month, two months of charging money is basically enough to change the group of batteries.

<> lithium batteries for low-speed electric vehicles.

Before buying a lithium battery, see if the battery cell used is a product, the quality of the battery determines the quality of the battery, such as capacity and energy density, etc., and then find a lithium battery produced by a large manufacturer, the production process is mature, the after-sales service is guaranteed, and the lithium battery market reference price is 1250 yuan. If you need to run long distances, it is best to install a range extender, with which you are not afraid of running out of power halfway, it can help you gallop without worry.

Because the cruising range of low-speed electric four-wheeled vehicles is still relatively limited, can not fully meet the daily travel needs of the public, if you want to increase its cruising range, you can install a range extender, in order to increase its cruising range, increase its range of activities, meet the daily travel needs of the public, and realize the freedom of travel, no longer due to the lack of power halfway and difficult.

The range extender can be purchased directly from the manufacturer, and the manufacturer will ship it directly, which will be cheaper. It is necessary to choose a range extender produced by a large manufacturer and a big brand to have a comprehensive guarantee of quality, performance, technology, after-sales and so on, otherwise if it is a small workshop-type manufacturer, it is easy to break and there is no guarantee in all aspects.

Recommendations for the use of range extenders:

It is not recommended to start the range extender when the battery is full, and it is generally recommended to start it when the battery is only 30%-40%. There is no particularly good effect when starting when the battery is full, in order to be environmentally friendly, it is recommended to start the range extender when needed, battery pollution is more serious than exhaust gas pollution, and protecting the battery is to protect the environment. It is not recommended to use it when the battery is not a little charged, the range extender is electric when it starts, and it may not catch fire when the battery is not charged at all.

I have long been from high-rise buildings, to downstairs electric bicycle charging place, experienced.

In order to ensure the life of the battery and ensure the safety of transmission, it is necessary to use an ultra-low voltage drop charger, and I not only use the ultra-low voltage drop linear stability guarantee line assembled by all discrete components, but also use imported ultra-low voltage drop linear integrated circuits, and also use switch modulation integrated circuits.

The problem you mentioned is caused by the low level of design of general e-bike chargers and the high pressure on cost constraints. For high-energy batteries, it is emphasized that the temperature rise of the battery should be continuously monitored; For lead-acid batteries, their tolerance is much stronger, and if the temperature rise of the lead-acid battery is too high in the charging state, it has been charged very seriously.

The simplest way is to connect the ammeter in series, manually monitor, and manually convert to a low float charge voltage in a timely manner according to the actual situation; The obstacle is that charger manufacturers are now keeping the line secret, and it takes a few days to slowly interpret the assembly distribution of the line in detail, and redraw the circuit diagram in reverse engineering before formulating modification measures.

The greater difficulty is that now the method of charging several rated voltage 12 volts batteries in series has serious defects, after dozens of charging cycles, the capacity of each battery, the voltage difference of each battery is getting bigger and bigger, even if manual intervention in charging, it is a drop in the bucket, helpless, anxious, unable to help.

The complete solution is a charger for each battery, and each battery has an independent voltmeter and ammeter for continuous monitoring, which is not the current three-stage charger or the "computer intelligence" charger advertised by the company.

I have always wanted to fully disclose the relevant design and a large number of test data free of charge, you want Ye Qin, Hu Jun, Jiang Shuzhuo to open the free teaching network, as well as the publishing house they are in charge of.

Customized lithium battery, appearance, voltage, internal resistance, capacitor can be customized.

Ten years old factory, you can contact me.

The battery is ** produced.

The original one is not possible with fast charging, however, you can match it yourself

1. The battery generally retains more than 20% of the battery, and the chemical conversion efficiency of the battery is about 50% when charging, and the power needs to be increased by 150%*80% when the battery is fully charged.

2. The optimal charging current of the battery is 10% of its capacity, however, the charging time needs to be 150%*80% 10%=12 hours, plus about 1 hour of segmented charging time.

3. In order to meet people's work and rest time, in the design, the charging current with a capacity of 13% is generally used, so that the charging time is at least 150%*80% 13%=hours, plus about 1 hour of segmented charging time.

4. Fast charging, generally charged with 20% of the battery capacity, the charging time is 150%*80% 20%=6 hours. Although the charging time is shortened by charging with a higher current, it is harmful to the battery, so use it with caution.

5. If you use a 20ah battery, at present, the charger is designed according to the charging current of about 15% of the battery capacity, so you can buy a charger with a capacity of 20ah*20% 15%=27ah.

Yes, but it will wash out the battery.

1. Charge frequently to avoid "deep discharge". Riding an electric vehicle should develop the habit of charging on the same day, no matter how far you ride every day, it is best to fill up the battery no matter how far it goes, and don't wait for it to run out before charging.

2. When the battery is charged in the car, the electric door lock should be closed, do not charge the battery upside down, and try to fully charge it once when charging. If there is a peculiar smell or the battery temperature is too high during the charging process, the charging should be stopped immediately and sent to the Luqing Technology Department for maintenance. When removing the battery to charge, do not touch the ends of the electrodes with wet hands or metals such as keys to avoid burns.

3. When not in use for a long time, it should be charged every month, and the battery should be stored after being fully charged.

4. Use a special charger when charging. Due to the different battery formulas and processes, the technical requirements for the charger are also different, which kind of charger can be charged with what brand of battery can be filled, are not the same, so do not mix chargers.

5. In order to protect the battery, the user can charge it at any time, but can not use the rising voltage to drive to prevent serious power loss, and when the battery is out of power, the power should be turned off to ride.

6. When charging, do not stop charging immediately when the charging indicator shows full charge, and should float for another 1 hour.

1. Keep the battery fully charged, ride the electric moped every day, no matter 10-15km, it should be recharged, so that the battery is in a "full state" for a long time, and it will be charged on the same day. After being used up and idle for a few days before charging, it is easy to have extreme vulcanization and a decrease in capacity.

2. Carry out regular deep discharge: It is recommended that you carry out a deep discharge after two months of use, that is, ride for a long distance until the undervoltage indicator flashes, the power is used up, and then charge to restore the battery capacity, which also makes you know the current capacity level of the battery and whether it needs maintenance.

3. It is forbidden to store the battery with power loss: the battery will affect the service life, and if the idle time is long, the battery will be damaged.

4. Regular inspection: If you buy a new car for 50km, within three months there is a serious reduction in the continuation, such as more than ten kilometers, at this time you can use a multimeter to check the voltage value of the external terminal post of the battery, the general full charge should be 39-42 volts, if a few volts less, or open the battery box one of the battery voltage is lower than volts, it may be an internal single grid short circuit, at this time should find a maintenance station to repair and replace, so as not to damage the other two good batteries. The charger should also be checked for malfunction.

5. The design load of the electric moped is 75kg, so avoid carrying heavy material parts, and please use your pedals to help when starting and going uphill. Therefore, at this time, the motor current increases, so that the battery discharges too quickly, and the voltage drops rapidly. The smaller the depth of discharge of the battery each time it is used, the longer the life of the capacitor.

Therefore, reducing high-current discharge can prolong the battery life and increase the driving range. In addition, no matter how large the capacity of the battery is used, users should develop a good habit of charging at any time.

1. It is normal for the battery capacity to drop with the drop in temperature in winter, with 25 as the standard, and the general -10 capacity is 80%.

2. Keep the surface of the battery clean for a long time, prohibit exposure to the sun when storing the car, and place the car in a cool, ventilated and dry place.

There is another set of batteries, 6 12v = 72v.

The charger is 72v2ah, current, 12ah battery can also be charged.

The 3 batteries are only 36V, connect the negative pole, and charge with a 72V charger, which will charge the battery. Change the charger to match the battery charging, or connect the 72V battery to charge.

The output of your electric car charger is 88V, you can't charge three batteries, this battery has another plug, which is connected to another set of batteries for series charging, if you use a 36V charger to short the other plug, you can't use this charger, it will directly charge the battery.

Isn't this all connected? Unless the plug is not compatible with the socket, it should be charged normally.

Hello, I see that there may be no power on the other end of you**.

Now more and more friends use electric vehicles as daily transportation, electric vehicles use lithium batteries for power supply, so how to charge lithium batteries for electric vehicles, the following will introduce to you the lithium battery charging related matters of electric vehicles. How to charge lithium batteries for electric vehicles.

1. When charging for the first time, it is the same as the usual charging, no special treatment is required, and it can be charged for eight to twelve hours; 2. The special charger provided by the lithium battery manufacturer must be used for charging, and the output port of the charger must be connected to the battery first, and then the charger must be connected to the power supply;

3. Since the lithium battery has no memory effect, it can be charged at any time, which is good for the life of the battery, it is recommended to charge it for eight to twelve hours each time, and the longest time should not exceed one day. In the case of long-term non-use, the lithium battery needs to be charged for two hours every two months, otherwise the battery performance will be reduced;

4. In addition, try not to charge the battery when it is completely discharged, it is best to charge it as you go, and charge it shallowly;
