Weak current College】 【electric vehicle battery damage causes】.

Battery power as a "convenient" has been widely used in the year 2003 to be used directly but also ordinary people, with electric vehicles in our popular degree unceasing enhancement, the battery more and more close to people's life, but also on battery knowledge little is known about how bad loss: battery too quickly, the capacity reduction of battery can repair, maintenance of the battery and questioned in this we only on electric vehicle battery bad loss causes, repair, maintenance of the following for reader reference.

General use of electric vehicles is maintenance-free lead acid battery, the electrolyte is a colloidal form, 24V, 36V, 48V or 60V. 36V 48V on the market and more of 60V, 24V and. The second section, 24V 36V 48V for three, four, five section 60V single 12V batteries in series from; single battery 12V, each section is separated by 6 every concatenation of 2V, every has positive and negative plates and colloidal electrolyte. Cause battery bad is complex, roughly divided into the following six categories:

1, "" overcharge "lead battery bad loss.

"Overcharge" is too much to the battery charger and a battery of chemical and physical properties from destructive phenomenon.

"Overcharge" first is the charger. Current electric vehicle charger has a security charge voltage setting, charging voltage General set in battery standard voltage 1.2 times, such as 48V battery, charging voltage setting within the 57.2V. Battery in the discharge process, voltage will gradually decline, when once again to the battery is charging, the red light will light up the charger, charging, when the battery power input repeatedly, the voltage is rising, until the close or equal to the voltage of the green light will light up when the charger, charging stops or trickle charging. If the charger voltage component failure, charging will not stop the charging current is continually enter battery, the voltage is rising, the voltage increase result will increase the thermal reaction of electrolyte, ranging from battery shell deformation (expansion), the lead storage battery is charging and exploded.

Secondly, because the battery voltage unbalance of cause "overcharge". The above said, battery group is composed of 2-5 section of battery 12V, battery just the factory, each section of the battery voltage is very close to deserve a group, but after some time, battery voltage is between the variance, that is, the so-called "pressure drop". Electric car charger when charging is at the same time-line of battery charging, voltage higher battery will be fully charged, the battery voltage is low after the full or even been charged, since the charger is to overall voltage for charging or stop charging set, therefore, the first fully charged batteries will be "overcharge" State Department. "Pressure" hours on battery has little effect on the "pressure", often "overcharge" as the battery will generate increased electrolyte thermal reaction until the battery charging and this section.

2, "" lack of electricity, "lead battery bad loss.

"The lack of electricity" is the battery, the voltage low forcing excessive discharge when a damaged battery plate coating phenomenon. You know, any vehicle-mounted electrical voltage has a standard range, more than the range appliances easy to short-circuit or even burned down below this range appliances could not start or function properly, even from life, car electrical equipment and batteries. Many users tend to use electric cars is charging a few days, there are daily trips over new battery standard mileage by more than 60%, to know that the battery capacity drops can cause the battery voltage is low (low voltage), brownouts, will not be able to effectively meet the on-board electrical voltage supply, basically when the voltage drops, users in the use of electric vehicles, battery cannot provide normal voltage, so it will load due to in-car electric makes battery under-voltage appear "lack of electricity," regular "deficient electrical" will make the battery plates lead layer gradually peel off until the plate bad loss.

3, starting, accelerating, overload resulting high rate discharge the battery bad loss.

Electric start, accelerate the moment current is large, typically reach 20A-50A, depending on the size of the electric motor power, normal discharge current general control within the 10A. As a result of instantaneous current is too large to make a dramatic increase in electrolytic reaction, plate coating must be subject to a certain degree of influence over the plates lead layer powder will be instant and high current pull gradually shedding, electrolyte is black (lead by), the battery will be scrapped. Overload is electric cars load weight in motion, such as excessive loading, manned, overload makes the battery discharge load increase, long hours of high-current discharge, have a direct impact on the plate coating, speeding up the process of softening the plates. There is no good road conditions will make electric cars-propagation of brake and start. Such as potholes, theirs, roadblocks, and so on. This is causing high load current factors. Also worth is, the greater the electric motor power, the battery life is shorter, this is because the motor power increases, the discharge current, on battery, the greater the injury also.

4. plate vulcanizing lead damage battery is bad.

What is a battery on a curing? in the plate produces a white crystalline solid lead sulphate, while charging, it is very difficult to translate into active substances of lead sulphate is Kraft, hereinafter referred to as "curing". Generate this kind of lead sulphate is a discharge or discharge after long-term placement, lead sulfate particles in electrolyte is solubility, saturation, these lead sulfate when the temperature is low, while the ReCrystallize in Crystal quality lead sulphate is precipitation. This particle precipitation in once on a time and again due to temperature changes in growth, development, increase the crystalline grain. This lead sulfate resistance of the electrical conductivity of the bad, and the large, solubility dissolved speed and very small charge recovery difficult. Thus became the capacity reduction and shortened life expectancy. Vulcanization is battery capacity reduction of major sticking point, however, large current damage battery plates is EV battery capacity reduction and greater problem.

5, the "losing" so that the battery is bad.
BR > the "loss" is the basic battery capacity reduction. Most of the electric vehicle use is maintenance-free lead-acid batteries, many users would say, this type of battery is sealed and maintenance free, why is there a "loss" phenomenon? their logic is simple, the water is important for electrolytic reaction batteries, rechargeable battery, once seen, high-current discharge, internal resistance increases, the short, easy to produce heat and steam, the steam in a sealed battery box will most be retained, but there are very few parts will loss (due to battery shell material density of the decision), the passage of time, the battery will appear the "losing" status. In General, the electric car battery 6 months or more will present the "losing" status, motor power increases, the "losing" status, the more serious.

6. other reasons for making battery bad loss.

In addition to these main battery bad loss, poor quality, battery, the electrolyte leakage plates, shell breakage, battery terminal fault is the cause of the loss of battery bad, this is not a commentary.
Battery power as a "convenient" has been widely used in the year 2003 to be used directly but also ordinary people, with electric vehicles in our popular degree unceasing enhancement, the battery more and more close to people's life, but also on battery knowledge little is known about how bad loss: battery too quickly, the capacity reduction of battery can repair, maintenance of the battery and questioned in this we only on electric vehicle battery bad loss causes, repair, maintenance of the following for reader reference.

The second section, 24V 36V 48V for three, four, five section 60V single 12V batteries in series from; single battery 12V, each section is separated by 6 every concatenation of 2V, every has positive and negative plates and colloidal electrolyte.
