The C5 rated capacity of the forklift battery

by:Vglory      2020-08-20
C5 rated capacity is the industry standard for forklift battery, in South Korea, Japan, Europe and some countries in C6 as reference discharge time, C3 is sight-seeing cars and maintenance-free battery, requires the capacity is very big, C20 is to start with lithium batteries, is that the car battery, C10 is solar battery, of course, some factories also to C20 as a benchmark, forklift battery rated capacity is a concept of power. It refers to a single lithium-ion batteries, when + 20 ℃ to 5 hours of discharge rate reached the final voltage is 1. That is released by 0 v power to Ann ( Ah) Said. The rated capacity of lithium-ion batteries in the selection of lithium-ion batteries is particularly prominent, mainly because it is the concentrated reflection of lithium battery performance, including the number of monomer, charge and discharge performance, aging factors, etc. Lithium battery capacity needs to be established on the basis of the lithium battery performance, mainly by a large number of trials to obtain relevant data. To the use of data, some lithium battery manufacturers have the software, can according to user needs to provide the curve of the specific conditions. Selection of forklift battery rated capacity, the first input parameter is the lithium battery power supply load power ( P) The time ( t) The average voltage value and lithium battery discharge ( U) 。 According to P, t, U, can determine the discharge rate of lithium-ion battery, in the curve of the discharge rate capacity checking. Lithium battery power supply load sort is more, among them, the power consumption of the vehicle emergency ventilation effect to the rated capacity of lithium battery. The second input parameter is the monomer quantity lithium-ion battery pack, it with the rated capacity is a set of parameters of complement each other. Quantity is less, the lithium battery monomer to terminate the higher the discharge voltage, to meet the requirements of the same load power supply, the greater the rated capacity of lithium batteries, but lithium batteries to terminate discharge voltage value should be lower than lithium battery stable discharge voltage, otherwise, the utilization rate of the lithium battery is low. The third input parameters, performance parameters, including charging performance and discharge performance, aging factors, they are mainly as the redundant coefficient of lithium batteries, provides the calculation basis for the determination of ultimate capacity of lithium-ion batteries. This paper, taking a subway project in use of lithium battery charge and discharge performance as an example. In the late stage of charging, lithium battery capacity is nearly constant, and the constant value is generally lower than the rated capacity. Will the actual value and the nominal capacity percentage as charging coefficient, become one of the selection of rated capacity coefficient, in order to make sure the actual usable capacity can meet the demand of power supply.
