What is the charging voltage of the electric vehicle?

48 v electric cars are also divided into electric cars (that is with pedal) and electric motorcycle. Analyzing by tracking feedback information statistics, lead-acid battery of electric vehicle life having short cycle life may because of the water loss and sulfide. Electric motorcycle lead-acid battery life is also affected by large current discharge, which often leads to positive plate to soften. This softening of the positive plate is a physical damage, and it is irreparable. Water loss and vulcanization are physical damage, which can be restored. Taobao has what we made in Jinzhou, white battery capacity restorer, can repair sulfide, then add some water to the accumulator. Those four basic batteries can restore the capacity of the battery to around 85%. The following is a friend who buy sea battery capacity restorer. From his evaluation, he is professional.

Taobao sea, about 48 v battery capacity restorer of professional evaluation: "very magical, installed capacity of the restorer, I try to feed fresh water into the battery: first uncovered the lead-acid battery sealing strip per day, with a rubber cover, each filled with battery supply liquid, open wide type charging to the full, remove the overflow liquid, covered with rubber cover, AB glue sealing on the sealing strip, the capacity of necessarily rose from 20 to ninety-five, darling, really great, the province 7800 ocean, by the way, my battery is 48 v20a, with electric heating silk string before the battery discharge at the poles of each battery voltage, the difference between each section no more than one v, suggested friends check beforehand, and conditions are simple! Buy a heating wire is cheap, no way to long in the new, make section used batteries is about forty, deserve to go up the restorer, overall province big price, thanks for patent, thank you for your dedication!!!!!!"

1, the battery is not the car boss said that two pieces of battery lags behind, which might affect the entire group of battery discharge capacity.11 v and 10 v that two pieces of voltage drop quickly, and it is easy to form a discharge and damage.

2, in the two pieces of old batteries, four pieces is about 12 v, add some water, reoccupy white best battery capacity restorer except the sulfide, mileage would be more than the original, and is often not just a little more.

3, maintenance-free also need to add water and sulfide, the top cover plate stand aside, will see six and fluid. After adding water, sea, battery capacity restorer in addition to the plate, with luck, the four groups of battery capacity will reach more than 85% of the new battery, save the cost for battery 7800.

4, he changed the old battery method, it is very economic. But not the most economical, the most economical is fill some water, and then on Taobao buy a white battery capacity restorer to in addition to the vulcanization, this method is the most economic. You will be like the friend, save several hundred lead-acid battery replacement costs.

It took more than 1 year, basic whole group batteries should be changed

Charging what is only temporary,

Is based on a full charge, the voltage, but the power went out for a while, it will change the battery

1. Battery not line, that is to say the battery life can't, you are the two pieces of low voltage if a separate charge, can also charge is so high voltage

2. If the two is better than two pieces of original, in the range of natural increase

3. All batteries are now free maintenance, not as before to add water, but with a prosthesis and regularly add liquid to maintain or to extend battery life, general theory is extended three to six months

4. This method is only temporary,

It is best to use the battery power meter measurement under the stand or fall of each battery, he then changed into new, usually pay attention to don't drive to the battery is still open, often charging at ordinary times, but don't charge for too long

"My country is good," the friend said very reasonable, the view of Mr Abt-bj is about the same, he thought the lead-acid battery sulfide removal is using pulse to non-destructive repair. And done the experiment, the following was written by his pulse in addition to the sulfide contents:

To eliminate the negative plate vulcanizing experiment is such a process:

First is the preparation of lead sulfide battery samples: take 200 lead battery to do test samples, only 100 of them do not cure the deep cycle life test, for the life of the battery; Another 100 to completely discharge the battery only, and should in 40 ℃ under the condition of high temperature storage of 90 days, according to Swedish chemist Allen Wu Sri Lanka program that three months storage of 40 ℃, the equivalent of 25 ℃ storage for 12 months, thus formed the sulfide lead-acid battery negative plate vulcanizing samples.

Pulse generator, and then reuse the validation tests of sulfide battery samples, repair, edge sampling capacity recovery tests, until capacity is no longer rising.

The third step is to repair the deep cycle life of battery do after test.

According to the results of the experimental data, the impulse to repair negative plate vulcanizing conclusion:

The conclusion is: the pulse repair of lead sulfide battery repair rate is as high as 97%, of which three only battery lead branch bridge leading to the single circuit, beyond repair. After the repair battery life expectancy is 98% of the average life span for the new battery!

According to the result of this, the national lead battery industry confirmed pulse repair sulfide results are true and correct.

But there is a situation in which you should pay attention to, it's likely have the phenomenon of voltage and capacity, although you around each battery voltage is 12 v, but the voltage does not represent the discharge capacity, discharge capacity is the capacity to represent, electric vehicle battery pack with group, is to go with group to capacity. Voltage, capacity may be there is a very big difference, water shortage and water shortages, capacity will be different; Sulfide and serious sulfide to a lesser degree, capacity will be different, so, you had better be after a full charge, discharge with the same current, to measure each battery discharge time respectively.

Old batteries must, of course, there are water loss, abt-bj teacher post, also mentions the electric water loss is a big reason of early failure. Is the best filling water first, then using pulse device removal of sulfide, the lead-acid battery capacity restorer friend said above I guess this is the kind of pulse generator, is designed to prevent and remove the plate vulcanizing. Finally, test the discharge time, that is, testing capacity.

Right, miss zhao also said that after filling water filtration battery, must rest, to ensure the water infiltration of supplement, otherwise, the effect will be discounted. My best to show your ability is limited, you search abt-bj, net is abt - bj technical post, read patiently, believe that after you electric car battery, will not spend how many money. Because there were too many can be replaced the battery pack, filling water, the removal of sulfide and recovery capacity.

As the boss is not black, you said in two pieces of 12 v battery to charge you $40, how much is 20 yuan, here also is 60 yuan. This kind of treatment is certainly the most economical, now we here, a group of 48 v20ah electric car battery, the worst brand also want to nearly 600 yuan, famous brand, such as day, amd, the lowest 700 yuan. Because of lead pollution, countries recently shut down more than 80% of the lead-acid battery small-scale production enterprises, the next step, estimates that still have to rise in price, learn the related knowledge is more necessary.

48 v battery set in the condition of full electric voltage at 53.2 V

48 V electric vehicles set by the voltage is 41.5 ~ 43.5 V, on the road must not more than by the voltage, don't stand for a period of time after empty electricity run again, can cause over discharge, adverse to the battery life.

48 V battery when charging the highest voltage at 59.2 V. Let stand for a few hours after a full charge after the voltage stability at about 53.2 V.

1, the no-load voltage charger - for three phase charger is float charging voltage, the voltage is usually a single battery is 13.5 v to 13.5 v (generally marked the battery, also can find it out according to the manual), then for 36 v is: 40.5 v to 40.5 v, 48 v for are: 54 v to 55.2 v. Therefore the error of considering your multi-meter, 53.6 v and 55.6 v seem to belong to normal, after all, has entered the stage of floating and has set up a lamp, so the value is not very demanding.

2, charger of the termination voltage - this is the so-called turn lamp voltage, voltage is usually a single battery is 14.4 v to 14.4 v (generally marked the battery, also can find it out according to the manual), then for 36 v is: 43.2 v to 43.2 v, 48 v for are: 57.6 v to 57.6 v.

3, The actual charger of the termination voltage - as for sealed battery, its value should be 2.4 v per cell, the corresponding voltage are 36 v to 43.2 v, 48 v to 57.6 v. But in fact is to raise the value, consider r charging time and fully charge, namely 36 v 44.4V 44.8 v, 48 v to 59.2 v to 59.2 v, but it is easy to cause water loss and shorten the battery life. It is not easy to find out the truth, as long as know how to determine the voltage value.
