Lead-acid battery works Principle聽 Lead-acid power charging and discharging of the electrochemical reaction process may be the process of charging, lead sulfate to form lead oxide, lead oxide as well as reduction of discharge with lead sulfate. The lead sulfate crystals is a very easy matter, when the battery electrolytic solution of sulfuric acid within the concentration of lead in your static idle time is too high or too long, they will "hold a" group, to form small crystals, and appeal to around these small deposits lead sulfate, as the inertia of this formation of large snowball as the crystallization of lead sulfate crystals when the charge not only can not be reduced to lead oxide, but also precipitated the board mounted on the electrode, resulting in any decline in working area of electrodes, this phenomenon is called sulfide, which is often said that aging. At this time frame the battery capacity might gradually decrease until useless.
Special working environment of electric bicycles
As long as lead acid batteries are recommended in the curing approach, but other than the actual field of lead-acid variety electric bicycle with lead-acid batteries come with a longer life, it is because lead-acid battery electric bicycle comes with an easy cure work surrounding.
鈶? depth of discharge Used lead-acid batteries in the car when the one-way only in your discharge ignition, ignition battery automatically charged after the generator will not purpose the battery depth connected with discharge. The electric bicycle can not be charged when riding, often more than 60% of the range of discharge, deep release, lead sulfate concentration, sulfide would be very serious.
鈶? large current discharge Current electric vehicles is generally 20 km cruise 4A, this value is higher than other areas of typically the battery current, while speeding the work overload of the up-to-date electric cars is even greater. Battery manufacturers have long been 1C charge 70%, 2C 60% of the discharge cycle life try out. After such a life test can be achieved 350 charge and discharge cycle life of this battery a lot, but the actual effect will be far in the use of the. This is because the large current increase of 50% of this work of depth involving discharge, the HP EliteBook 6930p Variety will accelerate curing. Therefore, the electric three-wheeled sport bike shorter battery life because the body is too major three-wheeled motorcycle, working current up to 6A above.
鈶? high frequency discharge Used in the field of battery backup power give, and only during capability outages will discharge, if the stop 8 times annually electricity to reach 10 years of life, only carried out 80 cycles charge everyday living, and electric vehicle request and discharge cycles a year 300 times or more tend to be.
鈶? Short Charge As electric bicycles are motors, not much time towards charge, to be completed within 8 hours from 36 volt or seventy two volt rechargeable 20 Goodness me, this must raise typically the charging voltage (typically step 2. 7 to 2. 9 V single-Festival), when the charge single-cell voltage exceeds a voltage of oxygen story (2. 35 V) or even hydrogen-voltage (2. 42 V), the battery will be open due to excessive oxygen evolution and then the exhaust valve, causing drinking water loss, so that a electrolyte concentration increased, the phenomenon of increasing sulfide variety.

鈶? charge after discharge can not be timely As a moving, charging and discharging from electric bicycles are completely separated in the difficult conditions in a timely manner after discharge charge, and discharge of live sulfate formed after a large number of hours without charge if more than half reduced to lead oxide, sulfide will form crystals.
The Getting Equipment
Widely circulated saying the industry is: the battery is not worn, it is a bad charge. In order in order to satisfy short-term electric bicycle high-capacity rechargeable battery, charging in the three-constant voltage current minimize, had to constant pressure by increasing the worthiness to 2. 47V ~ 2. 49V. In this manner, much higher than the actual battery voltage of oxygen evolution at the positive plate and bad plate hydrogen evolution voltage. Some charger manufacturers of products in order to reduce the charging precious time of instructions, improved float switch current constant tension, and making full power after charging indicator, there is no full power to repay by increasing the move voltage. Thus, many of this charger float voltage as compared with single-cell voltage 2. 35V, so that a large number of oxygen evolution is even so floating stage. The electric battery in poor oxygen lymphatic circulation, so that the uses up are constantly floating cycle. High constant value to ensure that the charging time, but the sacrifice is the the water loss and cure. Low constant value, and charge into the battery charging time is difficult to guarantee. The battery in boosting battery grid alloy to improve the analysis of air potential, improve oxygen move performance, improve the efficiency of sealed response based on the control of the highest possible charging voltage 2. 42V charging less, that is, hydrogen evolution potential in the following. This will inevitably result in the extension of that charging time, which must be charged in the higher current (limiting charge) of this state, adding to the polarization of this negative pulse, to enhance the battery's charge acceptance in your high current charging more than filled the time A number of power and reduces the charging time. 70% of the 2C charging current, battery charge acceptance is relatively large when using large current charging typically the HP Compaq Business Journal 6535b Battery, damage towards the battery is relatively smallish. Basically, the battery voltage is not higher than that from a serious hydrogen evolution. Once above the hydrogen evolution voltage, the battery will be fast water loss. The use of such chargers, must be a regular charge and discharge a few days if the half-way end charging, the battery will have a more serious lapse too rapidly curing. And users use the battery, is no guarantee that after each make use of, are able to charge in time, occur several times inside a year the situation is not promptly charged, the battery will be the accumulation of sulfide. Most chargers manufacturers say the depot because of the price factor does not even accept the charger can certainly guarantee the battery existence. Admittedly, this is most smaller businesses is the case, however, for development, the scale of the large companies do not chose the expensive good charger. Some charger manufacturers to exaggerate certain features, not the effectiveness with its promotional products too. There are many features to sell the concept of function, effectiveness is limited.
Other reasons Many cells in the single test, it could possibly get good results, but the battery pack for the thread, because of capacity, the open rounds voltage, state of request, curing varying degrees, the difference will be in series with the battery power is expanded, a single experience of the poor state of the entire group of energy, their life significantly decreased. Cong charge the battery in the production line, to the user with the help of car after car use this time to go through many Huanjie interval of one's or even for many weeks, in this period, as not to supplement the battery capability, resulting from the being let go of lead sulfate good sized accumulation of crystals, the user just purchased a new battery may have been reported to charge the battery and even aging. When the battery manufacturers within the implementation of quality self-confidence, on the recovery from the battery is not 100 % eliminated. After back to back the battery, the battery manufacturer to re-charge not to mention discharge test, the test often found in more than 60% from single cells is inconsistent aided by the conditions of the batteries oh no - back. The reason for that is in series together with the battery pack, the individual behind the formation from the entire set of battery pack cells function decline caused by the whole group in to back. Many battery manufacturers to take back to back aided by the battery group, pay, in addition to sulfur, packaging, again available to users to increase the actual effective battery life, reduce scrap, reduce some of this battery manufacturer's claim for loss of management Therefore, many dealers have already felt the battery was provided by the manufacturer, "Generations. " Electric vehicle HP Compaq 6735b Variety when used properly, the general problem of the battery is absolutely not used for 3 years perhaps, on the contrary, greatly reduce the service life might be short. Therefore, consumers daily maintenance from electric vehicle batteries electricity car battery life is to determine the key. <! --INFOLINKS_OFF-->.
