Description
Technical Field
The application relates to the technical field of new energy, in particular to a method, a device, electronic equipment and a medium for dynamically correcting SOH based on the Internet.
Background
The battery capacity of the new energy vehicle power battery decays after a plurality of charge and discharge cycles. Excessive current accelerates the decay of battery life if SOH (State of Health, which is a State of Health of the battery in the industry) is not known. Therefore, accurate estimation of SOH is of great importance.
The current SOH calculation method of the new energy vehicle battery comprises the following steps: one method is a discharge experiment method, in which a discharge device is used to discharge the battery from full charge to the cut-off voltage of the battery, and the SOH of the battery can be calculated by comparing the discharged electric quantity with rated capacity. One method is an internal resistance calculation method, wherein the larger the internal resistance is, the smaller the SOH is, and the internal resistance of the battery is calculated through battery data such as current and voltage, so that the SOH of the battery is estimated. The other method is a battery cycle number folding algorithm, and the SOH of the battery is corresponding to the battery cycle number, wherein the more the cycle number is, the smaller the SOH is, namely the worse the battery state of health is.
The discharge experiment method cannot calculate SOH on line, and can only be used for testing in a laboratory. The internal resistance calculation method has larger SOH estimation error as the battery internal resistance changes smaller relative to SOH. The battery cycle number folding algorithm roughly corresponds to SOH according to the cycle number of the battery, for example, if the battery is charged and discharged twice rated capacity every time, the cycle number of the battery is increased by one, and finally, the SOH at the moment is obtained by looking up a table according to the relation between the cycle number of the battery and the SOH. The method has single calculation dimension and poor adaptability.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) through which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user may be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user may be received in any form, including acoustic input, speech input, or tactile input.
The systems and techniques described here can be implemented in a computing system that includes a background component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such background, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the internet.
The computing system may include clients and servers. The client and server are typically remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical hosts and VPS service are overcome.
