II. Standard Containerized Battery
The Standard Containerized Battery is a modular design platform whose core advantage lies in enabling flexible and cost-efficient configurations through standardization.
1. Design Principles:
1） Case Standardization: Offers multiple standard-sized battery containers, including the C Container (L1060×W630×H240) and the G Container (L950×W630×H240), to accommodate diverse spatial layout requirements.
2） Flexible Assembly: The platform supports various CATL battery cell capacities such as 173Ah, 228Ah, and 302Ah. By varying the number of battery cells connected in series within each container and configuring containers in series and parallel arrangements (supporting multi-string configurations), the system achieves a wide energy capacity range from approximately 90kWh to nearly 600kWh, catering to different vehicle models and operational scenarios.
