Embodiment Construction

[0027] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0028] Good control of the battery of the train is an important part of ensuring the operation of the train. In the related technology, the train is usually powered by all the battery modules, and the running energy required by the train is shared by all the battery modules. Therefore, even when the train is running at a low power, there are more battery modules at low power. Low working state, which will lead to low battery working efficiency and easy to reduce battery life.

[0029] In order to solve the above technical problems, this application provides a battery control method. The processing device can dynamically adjust the number of battery modules in the working state in the train based on the running state required by the train, so that each battery in the working state can All modules can have a relatively reasonable output power, improve the rationali...

Abstract

The embodiment of the invention discloses a battery control method. The method comprises the steps: acquiring a target running state corresponding to a target train; according to the corresponding relation between the operation state and the number of the battery modules and the target operation state, determining the number of the target battery modules; and adjusting the number of the battery modules in the working state in the target train to the number of the target battery modules. Processing equipment can dynamically adjust the number of the battery modules in the working state in the train based on the running state required by the train, so that each battery module in the working state can have relatively reasonable output power, the reasonability of power control is improved, and the service life of a battery system is prolonged.

Description

technical field [0001] The present application relates to the technical field of energy management, in particular to a battery control method and a related device. Background technique [0002] The train is a travel tool commonly used in people's daily travel, such as taking a train or a subway. With the continuous improvement of energy technology, more and more trains choose to use more environmentally friendly and energy-saving batteries as energy supply modules for operation. [0003] In the related technology, since the running status of the train may change frequently, and the power control of the battery module is not done well, it is easy to cause problems such as energy waste and shortened battery life. Contents of the invention [0004] In order to solve the above technical problems, this application provides a battery control method. The processing device can dynamically adjust the number of battery modules in the working state in the train based on the running ...
