Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] Combine first figure 1 Briefly introduce the principle of the power system of the vehicle. The circuit includes a generator, a battery and some parallel electrical loads. Partial loads, such as normally open loads, are always in working condition during the driving of the whole vehicle (such as ECU, TCU, electronic steering, instrumentation and other electronic devices necessary for driving). There are also some loads that can be turned on or off according to the driving conditions of the vehicle, the needs of the driver or passengers (such as headlights, turn signals, air conditioners, blowers, audio, seat heating, etc.), this part of the load is variable load. In addition, some loads continue to work after the car is locked ...

Abstract

The invention relates to an analog simulation method for automobile storage battery sizing. The method comprises the steps of (1) dividing a driving cycle into three working conditions including a parking working condition, a starting working condition and a driving working condition, and calculating charge-discharge situations and electricity demand situations of a storage battery under different working conditions; (2) inputting a rated capacity and an initial charge state of the selected battery, and simulating under NEDC (New European Driving Cycle) working conditions through a MATLAB (matrix laboratory); and (3) carrying out multiple cycles to obtain the capacity of the storage battery after one and a half years. According to the analog simulation method, all electricity demand working conditions, including the starting working condition, the driving working condition and the parking working condition of an automobile in the use process are fully considered; meanwhile, the influence of environmental factors is also considered, starting in the low temperature environment is added into simulation calculation so that a calculation result is accurate; in addition, a simulation process simulates the use condition of the storage battery in the whole life cycle, and one-sidedness caused by only consideration of a new battery is avoided. Meanwhile, the problems of frequent lack of electricity and difficult starting of the automobile and shortened life of the storage battery caused by improper storage battery sizing and cost waste caused by excessive battery capacity selection can be solved from the technical angle.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a type selection method for an automobile storage battery. Background technique [0002] With the development of science and technology, there are more and more electronic devices on the vehicle, so how to accurately design the power system of the vehicle to ensure the normal use of the electrical components of the vehicle has become very important. The total electricity consumption during the use of the car is a variable quantity, which depends on the number of loads turned on in the current state and the load power. Usually, the selection of each power supply device is determined according to the working conditions that the vehicle may encounter during its entire life cycle, so as to ensure the performance requirements of the vehicle power supply system. It mainly involves the research on the basic characteristics of the electrical system of the vehicle, especially the two...
