JD Energy is a Chinese startup operating in the renewable energy sector. The company specializes in energy storage and management, offering a range of products and services that cater to both commercial and industrial clients. Their offerings include the eBlock, eLink, and eMind, which are part of an integrated energy storage system.

The eBlock is a smart energy block product that combines long-life batteries, a battery management system (BMS), a high-performance inverter system, an active safety system, an intelligent power distribution system, and a thermal management system. This all-in-one design allows for plug-and-play functionality.

The eLink serves as a link between the energy flow and data flow of the storage system. It connects the eBlock with the user's power distribution system, controlling and measuring the output of AC power. It also acts as a bridge between the eBlock and the eMind, facilitating high-speed data communication.

The eMind is a product that aggregates and displays data from the energy storage system, controls strategies, analyzes operations, and mines big data. It can be flexibly deployed on public or private clouds. It uses a time-series database storage method, allowing for second-level display and storage of each cell voltage and temperature in the energy storage system. It supports the retrospective of operation data and fault breakpoint recording of the energy storage station at any time in the past.

JD Energy's business model revolves around selling these energy storage and management solutions to its clients. The company makes money by selling these products and providing related services such as installation, maintenance, and data analysis.
