A simple method is to measure the open circuit voltage of battery, which is using battery OCV curve and open circuit voltage curveBattery in the case of open is not pick up the load voltage is proportional to the battery capacity, for example, may represent 116 V battery capacity 13 V may represent 10% to 90%Different batteries have different characteristics, but in general as long as the open circuit voltage to 13 v basic capacity is above 90%The effect of voltage ammeter is not show the current value of the battery voltage and current, but the charger output current charging voltage and charging current.

Before nickel metal hydride battery is widely used, we tend to use nickel cadmium battery Because the cadmium in battery is toxic, it is now basically eliminated.

How do you calculate the number of connection batteries in series or parallel of a set of lithium battery need?Answer 1: simple, increase voltage series, in parallel to increase capacity, ternary lithium standard voltage 37 v, 4.

Lithium battery manufacturing process: in the former three working procedures accounted for nearly 35% / 30% / 35%Lithium battery production process is complicated, the main production process mainly covers the electrode made of coated stage (front), batteries of synthetic winding injection liquid phase (middle), and turned to encapsulate the phase of testing (section), value (purchasing amount) accounted for about 35-40% () : (30 ~ 35) % (30 ~ 35) %Differences mainly comes from the different equipment suppliers, the proportion of import/domestic differences, such as process flow, value deviation but overall than to have to meet the percentage.

The lithium battery industry development is very rapid, and it also has wide application We can say that our life of science and technology has been inseparable from the lithium battery.

Lithium battery profile"Lithium battery" is a battery using lithium metal or lithium alloy as anode materials, and non-aqueous electrolyte solution Lithium battery was carried out by GilbertN in 1912.

Some people thought that the better lithium battery brand, the higher the price is, better performance and even longer lifespan But that is not the truth, even if it is a good lithium battery, it may be over discharged.

The reasonable usages of lithium battery of electric cars are as following:1The battery do not need to "activate"Lithium battery does not need to be the first three time charge more than 12 hours, lithium battery no memory.

IEC International Standard IEC International Standard is a common standard in battery industry The IEC (International Electrical Commission) formulated IEC battery standard in order to promote the standardization in the field of electrical and electronic all over the world.

Currently, most of electric cars are using titanium manganese polymer lithium-ion battery, which is a kind of battery with high volume density, long life, repeatedly charging high frequency and high consistency If using quick charge mode, only one and a half hours, it can support a car to run 380 kilometers.
