Great Wall Motor presents a high-density battery for plug-in hybrids
The Chinese manufacturer Great Wall Motor has unveiled a new energy storage system intended for its upcoming plug-in hybrid models. This technological advancement focuses on a pack that uses large-format cylindrical cells, achieving a very high energy density level. The main objective is for the vehicles to be able to travel longer distances using only electric propulsion. 🔋
The technological base: large cylindrical cells
The heart of this innovation consists of 6-series type cylindrical cells, which surpass conventional variants in size. This design allows for a greater amount of active material to be included within an equivalent volume, thereby increasing the total capacity of the system. The chemical composition uses a nickel-cobalt-manganese (NCM) cathode and an anode that combines graphite with silicon. The module and complete assembly architecture is designed to dissipate heat optimally and ensure safe operation.
Key design features:- Uses large cylindrical cells (6-series type) to maximize capacity.
- Battery chemistry based on NCM for the cathode and graphite-silicon for the anode.
- Optimized pack structure for efficient thermal management and maximum safety.
This battery represents a firm step in the strategy to electrify the vehicle lineup, making electric mode the primary option for daily use.
Extending zero-emission range
With this development, the brand aims for its PHEV models to meet the vast majority of daily trips operating solely on electricity. This translates into a drastic reduction in fuel consumption and, therefore, in pollutant emissions in urban environments. The initiative is part of a global plan to electrify its product portfolio. Manufacturing of these new batteries is already underway at the company's own facilities. 🚗⚡
System advantages and objectives:- Extend electric range to cover daily trips without assistance from the thermal engine.
- Reduce fuel use and significantly minimize local emissions.
- Integrate the technology into the brand's next generation of plug-in hybrid vehicles.
A new competitor in the technological race
The presentation of this battery pack positions Great Wall Motor as another participant in the intense competition to achieve the highest energy density. The goal is clear: to ensure drivers forget about gasoline during their weekly activities, reserving the combustion engine for longer or occasional trips. This advancement underscores the industry's commitment to transitioning to more sustainable mobility.
