Embodiment 1

[0136] A method for selecting a rated capacity of a commercial vehicle valve-regulated lead-acid battery, comprising the following steps:

[0137] The first step is data collection and sorting: collect the power consumption information of each electric device for the vehicle to be selected, sort out and classify the battery power consumption items and power consumption time;

[0138] The second step is to establish a demand model: to establish a power consumption model required to meet the specific needs of high-power electrical equipment. Electricity demand and parking high-power equipment power demand are respectively established according to the power demand: start-up power demand model, static power demand model and conventional power consumption and parking high-power equipment power demand model;

[0139] The third step is to calculate the power consumption: according to the characteristics of the battery and the geographical distribution information, calculate separatel...

Embodiment 2

[0142] Embodiment 2 is basically the same as Embodiment 1, and its difference is:

[0143] In the first step, during data collection and sorting, the power consumption information collected for different types of power consumption equipment on the vehicle to be selected is different, and the specific content is as follows:

[0144] For conventional power demand equipment, it collects: working rated current, use frequency coefficient and 4-hour power consumption information;

[0145] For starting electrical equipment, collect its: starter power information;

[0146] For the static power demand, collect the static current information of each electrical appliance on the vehicle to be selected, and sum the static current of all electrical appliances to obtain the static current I of the whole vehicle S ;

[0147] According to the power demand of parking high-power equipment, collect its power consumption information in different use environments: rated power, rated current, work...

Embodiment 3

[0197] Embodiment 3 is basically the same as Embodiment 2, and its difference is:

[0198] In the first step, during data collection and sorting, the power consumption information collected for different types of power consumption equipment on the vehicle to be selected is different, and the specific content is as follows:

[0199] For conventional power demand equipment, collect its: working rated current, use frequency coefficient and 4-hour power consumption information; in ACC mode, the working parameters of electrical equipment are as follows: Table 3:

Abstract

A rated capacity type selection method for a commercial vehicle valve-regulated lead-acid storage battery comprises the following steps: step 1, data acquisition and arrangement: acquiring power utilization information of each power utilization device of a vehicle to be selected, and sorting and classifying power utilization items and power utilization duration of the storage battery; 2, demand model establishment: establishing a starting electricity demand model, a static electricity demand model and a conventional electricity demand model and a parking high-power equipment electricity demand model respectively according to electricity demands; 3, calculating the consumed electric quantity: respectively calculating the required storage battery electric quantity of the starting power consumption demand model, the static power consumption demand model and the conventional power consumption and parking high-power equipment power consumption demand model, and selecting the maximum required storage battery rated capacity as the storage battery rated capacity selection requirement of the to-be-selected vehicle; and 4, verification of a model selection result: selecting a storage battery meeting the requirement, and installing the storage battery on the vehicle to be subjected to model selection for real vehicle verification. According to the design, the model selection method is scientific and reasonable, and the model selection result is high in reliability.

Description

technical field [0001] The invention relates to a rated capacity selection method of a commercial vehicle valve-regulated lead-acid battery, which is particularly suitable for shortening the selection cycle and reducing the selection cost. Background technique [0002] The main function of traditional commercial vehicle batteries is to meet the needs of static consumption such as starting the vehicle and leaving it for a period of time. The demand arises at the historic moment. Under the influence of higher and higher demand factors, the whole vehicle puts forward higher requirements on the life of the battery, especially the deep cycle capability, so that the battery can still start the vehicle normally when the battery is discharged to a certain depth. Therefore, the selection of battery type is very important. Selecting the most suitable battery according to the needs of the vehicle and customers can achieve the goals of optimal vehicle cost, highest customer satisfaction...
