Abstract:

The development of power sources plays a vital role in green transportation, large-scale energy storage, smart grid, etc. Electrochemical power sources, usually, have complex reaction mechanisms, and multi-physic and multi-scale characteristics. Also, they exhibit strong nonlinearity, time-varying, and spatial distribution characteristics during operation, which brings challenges to battery management. The power battery is taken as the object, the current research status and technology development trend are reviewed from aspects of battery modeling, measurement, and management, and it is proposed that the local management will move towards global digital management. The concept of digitalized electrochemical power source aims to facilitate the development of electrochemical power source application scenarios, e.g., new energy vehicles, hydrogen energy storage, new power grids, and charging infrastructure.

Key words: Battery, model, measurement, management, digitalized electrochemical power source
