Measuring 4 power saving bottle to protect state, which is power saving and see bottles of lowest voltage compared with other sections, removed the power saving bottles, alone with a 12 v charger, press 2 current charging about 10 hours, reoccupy after full of around 25 watt bulb discharge 12 v to 10 v, calculate the discharge time, can see the battery discharge more than six hours;See if there are any increase several times cycle.If the discharge time is too short, you need to replace this section.Replace the former can also do some experimental such as distilled water and sulfuric acid can improve.Other sections can be single section after the electricity is full again, repeat several times the actual calculate the sections of the battery.20 ampere hour battery according to the single section 2 should be able to put electric current discharge 10 hours.

Li-ion battery electric vehicle is lithium battery electric vehicle, to pick up lithium ion batteries electric car.In recent years, the traditional internal combustion engine vehicle caused by the environmental problem and shortage of oil resources will make people out into the new energy vehicles.Pure electric vehicles with its can truly achieve "zero emissions" and become an important development direction of electric cars.Lithium ion batteries because of its excellent performance, become the ideal power source of the new generation of electric cars.

The traditional structure of lithium ion battery including graphite anode, and lithium ion cathode and the electrolyte in the composition of the metal oxide (organic solvent to dissolve the lithium salt solution).The most common form of lithium ion battery with carbon as anode, with six fluorine ethylene carbonate and dimethyl carbonate dissolved lithium phosphate solution as the electrolyte, cathode for lithium manganese dioxide acid;Light and strong, is greater than the energy, monomer voltage of about 3.7 V.

Compared with nickel metal hydride batteries, lithium ion battery has a relatively high working voltage and larger than the energy, is 3 times of nimh batteries.Lithium-ion batteries, small volume, light quality, long cycle life, low self-discharge, no memory effect and no pollution;A single battery performance index scale span is big, this is because the lithium ion battery electrodes have more combinations, they exist certain differences in performance.

Can be divided into lithium ion batteries and lithium-ion batteriesLithium polymer battery2.Lithium ion battery cathode materials mainly include lithium cobalt oxide, lithium nickel oxide, lithium manganese oxide, lithium iron phosphate, etc., mainly include graphite anode materials, lithium titanate, etc.

When the electric bicycle lithium battery slowly becoming more and more popular in the market, a lot of people for electric lithium battery charging method is not very clear.How to charge the lithium battery electric vehicles and maintenance?

1, the new battery charging method

For lithium battery "activate", this statement, it is an old topic, a large part of consumers think it need to activate the battery, almost all of the sales staff said, the first three time charge batteries are to be full of 12 hours, this is obvious from the nickel battery, such as nickel cadmium and nickel metal hydride) continue down.So that, the outset misinformation, so to speak.Lithium-ion and nickel batteries charging and discharging characteristics have very big difference, and can be very clear tell you, I have looked at all serious formal technical data will emphasize overcharge and over discharge of lithium batteries, especially liquid lithium ion battery caused great damage.

You need to activate the battery?Answer is yes I case, need to activate!However, this process is done by the manufacturer, has nothing to do with the user, the user is unable to complete.Real activation process is as follows: lithium-ion batteries, lithium ion battery shell infusion electrolyte - seal - into, is the constant voltage charge, and then discharge, so for several cycles, the electrode fully infiltrates electrolyte activates, until capacity requirements, this is the content of the activation process, that is to say the factory after the lithium ion battery to user hand is already activated.In addition, some of which cell activation process need battery is in open state, activate again after sealing, unless you have the batteries production equipment, otherwise how to do?Battery from the factory, then sell to the user's hands, will experience a period of time, a month or a few months, as a result, battery electrode materials will be "passivation", suggested to use for the first time in manual battery most good three times I completely filling process, in order to fast speed to eliminate passivation of electrode material, I can achieve the most efficient I.But the process without the need for 12 hours, should be full of.Normal use for a period of time can also eliminate the passivation.New lithium battery in the process of activation, so users don't need special method and the device.

In addition, lithium battery or charger will automatically stop after the battery, there is no nickel electric charger of the so-called "trickle charging for 10 hours.That is to say, if your lithium battery, after full on the charger is Bai Chong.But none of us there is no guarantee that the battery charge and discharge protection circuit will never change and quality according to the features of foolproof, so your battery will may be on the brink of danger for a long time.This is another reason we object to a longer charge.On some machines, charging after more than a certain amount of time, if you don't go to remove the charger, the system does not stop charging, will also begin to discharge - charging cycles.Maybe this vendor has its purpose, but obviously is unfavorable for the life of the battery.At the same time, the charging takes a long time long, often need to be done in the night, and to power grid in China, many places are relatively high voltage in the night, and volatile.Have already said, in front of the lithium battery is very delicate, it is better than nickel electric resistance to fluctuation in charging and discharging ability worse, so it brings the risk of additional.

2, when in normal use should start charging

Because the number of charge and discharge is limited, so should be lithium battery electric light recharging as much as possible.But I find a lithium ion battery charge and discharge cycle experiment table, the data of cycle life are listed as follows: cycle lifetime (10% DOD) : > 1000 - cycle lifetime (100% DOD) : > 200 times the DOD is the abbreviation of the depth of discharge.From the table, but the depth of the number of charging and discharging, 10% DOD cycle life than 100% DOD much longer., of course, if the conversion to the actual charge relative to the total capacity: * 1000 * 200 = 200 = 100100%, 10% of the latter to fully charge and discharge is still relatively good, but in front of the net friend of the idea to do some correction: under normal circumstances, you should have a reservation, according to the principle of battery remaining power run out to refill charging, but if your batteries in your expected to 2 days can't insist on the whole during the day, it should start charging in a timely manner, of course, if you are willing to carry the charger to the office when BieLun again.

Believe that the vast majority of consumers have heard of, the life of the lithium battery is "500", 500 times more than the number of times, the battery will "die", many friends in order to be able to extend battery life, each time to charge when the battery run out completely, so really have a longer effect on battery life?Answer I case is no.

Actually there is a concept of error, the life of the lithium battery is "500", refers not to the number of charge, but a charge and discharge cycle, for example, to 40%, with a period of time after filling 20%, next time later, used by 30%, 20% next time...In the middle of the 20% that just added 10% of its electricity, a total of the total a charging cycle.After the next cycle.

A li-ion battery in the case of a day I took only a half of the battery, then charge for it.If so, the next day with half of the charge, the total charges down, it can only be counted as a charge cycle, instead of two.Often, therefore, may be charging after several times to complete a cycle.Each completed a charge cycle, power will reduce a little.However, decrease rate is very small, high quality battery charge cycle for many times, still will retain 80% of the original electricity.If A completely discharge of the battery is Q, A battery the cycle of 500 times, so it is in life to provide the total power of 500 Q, if we will be half charge electricity use, set number of charging for A, simply, A = 1/2 Q * Q, 500 should be A 1000 times.So for battery life, we can use the cycle to measure, but not to be measured by the number.

The principle of battery remaining power run out to refill is not want you to extremes.As widespread and long charging a saying that is "as far as possible to get all the machines with battery power, the most I use to automatic shutdown".The practice of this kind of practice is just nickel batteries, purpose is to avoid the memory effect, unfortunately it also circulates in lithium-ion batteries.Once someone because machines low battery warning, without a charge to continue using has been used examples of automatic shutdown.The results in this case the machine in the later charging and boot no reaction, had to send to the maintenance of the service.This is because the battery voltage is too low, caused by the excessive discharge that do not have normal charging and boot conditions.
