Jiangsu Shuangdengcun Battery 6-GFM-65 parameters
a Open circuit voltage: the terminal voltage of the battery in the open circuit state.
b Working voltage: the voltage displayed during the discharge process after the battery is connected to the load. The working voltage is related to the discharge conditions. The higher the discharge current, the lower the working voltage ; The lower the temperature, the lower the operating voltage.
two 、 Battery capacity:
a , battery theory Capacity: the active substance is higher according to Faraday's law theory Value.
b . Actual capacity of the battery: the power output of the battery under certain conditions. It is equal to the product of discharge current and discharge time. Company :AH 。
c Rated capacity of battery: according to the state or relevant ministry door The issued standard guarantees the battery's lower capacity under certain conditions.
Under normal circumstances, the relationship between the three is: theory Capacity>actual capacity>rated capacity .
three 、 Internal resistance of battery:
When the current passes through the inside of the battery, the resistance will reduce the voltage of the battery. The resistance of the battery is not a constant, because the composition of active substances, electrolyte temperature and concentration are constantly changing. The internal resistance can be divided into ohmic internal resistance and comparative resistance. The ohmic internal resistance conforms to Ohm's law ; The comparison resistance increases with the increase of discharge current, but it is logarithmic rather than linear.
four Positive active substance:
Positive active substances include α-PbO2 and β-PbO2 Two crystal forms. β-PbO2 It has high activity and utilization rate. α-PbO2 It has good mechanical strength and large size. When α-PbO2/β-PbO2 by zero point eight The battery has a good deep discharge capacity.
