Problems solved by technology

Traditional electric vehicle chargers are designed independently of the battery. Every time an electric vehicle needs to be charged, it must be connected to an independent charger or charging pile to charge, which is troublesome.
In addition, the traditional charger uses a magnetic core type electromagnetic transformer, which has the disadvantages of large volume, magnetic field interference, heat generation, low efficiency, and poor control accuracy.

Abstract

The invention relates to a built-in charging management type battery pack and particularly relates to a charger, a battery management system and a storage battery pack. The battery pack is mainly composed of a casing, a charging module, a management module and a battery pack body, wherein the charging module, the management module and the battery pack body are arranged inside the casing. The battery pack is characterized in that the built-in charging management type battery pack is designed specially, and module integration and functional optimization are achieved at the aspects of electronic devices, circuits (control circuits, voltage stabilizing circuits and detecting circuits), electromagnetic compatibility and heat management, so that the battery pack has the advantages of being small in size, light in weight, free from electromagnetic interference, stable in electrical performance, safe and the like, charging and management functions are integrated and built inside battery casings, batteries can be charged conveniently and quickly, the charger is not required to be carried with users, and the battery pack is low in charging energy consumption, high in efficiency, safe and reliable.

Description

technical field [0001] The invention relates to a battery pack with built-in charge management, which belongs to the field of new energy applications. Background technique [0002] At present, electric vehicles, especially electric bicycles and electric motorcycles have been widely used because of their advantages such as easy to use, labor saving, fast and environmental protection. In addition to caring about the service life of electric vehicles, users are also worried about how to charge and whether charging is convenient. Traditional electric vehicle chargers are designed independently of the battery. Every time an electric vehicle needs to be charged, it must be connected to an independent charger or charging pile to charge, which is troublesome. In addition, the traditional charger uses a magnetic core type electromagnetic transformer, which has disadvantages such as large volume, magnetic field interference, heat generation, low efficiency, and poor control accuracy....
