Storage battery pack and automobile with top-mounted electric drive operation function

Abstract

The invention provides a storage battery pack and an automobile with a top-mounted electric drive operation function. The storage battery pack is applied to the automobile with the top-mounted electric drive operation function, the automobile comprises an engine, and the engine comprises a generator. A shielding power supply and a battery module of the storage battery pack are electrically connected with the generator through a battery pack charging circuit; a management module can control the battery pack charging circuit to be switched on to charge the shielding power supply and the battery module when the engine works, and control the shielding power supply and the battery module to output power to supply power to an engine starter; when the engine stops, the shielding power supply is controlled to stop outputting the power supply, and the battery module is controlled to output the power supply to power electric equipment on the automobile; and when the engine is started, the shielding power supply and the battery module are controlled to output power to supply power to the engine starter. The storage battery pack can be used for avoiding the situation that the automobile cannot be started due to power shortage of the whole automobile storage battery pack.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a storage battery pack and an automobile with the function of top-mounted electric drive operation. Background technique [0002] During the use of vehicles, especially those with the function of electric drive, the battery pack of the whole vehicle is related to the normal operation of basic functions such as vehicle starting and electrical equipment. The following common conditions can easily cause the vehicle to fail to start normally, such as frequent parking and use of electronic equipment, frequent short-distance driving, external installation / modification of electrical equipment, excessive sleep current, driver forgetting to turn off the power, etc. It may cause the battery pack of the vehicle to lose power, which will easily affect the normal operation of the basic functions of the vehicle, and may even cause the vehicle to fail to start normally, which not only brings a...

Problems solved by technology

In recent years, people have also conducted a lot of research on battery capacity estimation methods, and achieved certain research results. The common research results include ampere-hour integration method, discharge experiment method, open circuit voltage method, neural network method and Kalman filter method, but It is difficult to obtain the estimated initial state due to the ampere-hour integration method, the discharge experiment method will be forced to interrupt the vehicle operation, the open circuit voltage method requires the vehicle to be stopped, the neural network method requires a large amount of reference data for training, and the Kalman filter method does not affect the hardware configuration. The requirements are relatively high, and the above research results have not achieved good results in application

It can be seen that the application of the existing remaining power SOC detection in the vehicle battery pack is hindered, which is not conducive to the solution of the above-mentioned vehicle battery pack loss phenomenon.
