Features of Concentrated Scale Power System
Power Consumption is Low High Dependability

Use a cutting-edge, high-efficiency liquid cooling system.
High levels of integration and consistency

The battery cluster has a horizontal configuration, and each cluster of wire harnesses is the same length , increase cluster consistency, and the system meets overall transportation and installation requirements.
The same platform on a larger scale

To enable platformization mass manufacturing, the DC side is compatible with 1000V and 1500V designs.
High-capacity non-walk-in
Non-walk-in integrated design, higher energy density in a single box, and high voltage.
The platform's capacity can be raised by 45%.
Security, subdivision

To improve the system, the liquid-cooled unit, battery, and electrical compartments are constructed individually.
Security performance of the system
Power Consumption is Low High Dependability

Use a cutting-edge, high-efficiency liquid cooling system.
