Product Highlights

High Energy Density

High Energy Density

Energy density increased by 50%. Integrated charge and discharge control saves floor space and civil engineering costs, facilitates on-site installation, and meets renovation demands in limited-space scenarios.

Low Attenuation & Long Lifespan

Low Attenuation & Long Lifespan

Adopting mature dry electrode technology, near 20 million cells have been fully verified in global automotive and power system projects. Superior consistency and long-term stability ensure prolonged system operation, with low attenuation in power output and backup duration.

Low-Voltage System Built for Durability

Low-Voltage System Built for Durability

Referring to the design of primary and secondary systems in high-voltage substations, the cabinet adopts separated power and control circuit layout. Data acquisition and control modules are independently replaceable. All core components comply with EMC Level 3 and higher standards, featuring high operational reliability and strong anti-interference ability to support long-term uninterrupted system operation.

Safe &Convenient O&M

Safe &Convenient O&M

Equipped with high-resolution touchscreen HMI for intuitive operation status display. Built-in charge-discharge units and maintenance isolating switches support one-click commissioning and maintenance. Dual isolation is applied to electrical circuits, while software and hardware adopt interlocking protection to ensure operational safety.
