On March 28, global battery manufacturer CALB officially debuted its mass-produced 400Wh/kg solid-liquid hybrid battery at the Hefei New Energy Commercial Vehicle Exhibition, with the system making its first market installation in Chery’s new energy light-duty mini-trucks. This milestone marks the first large-scale commercial rollout of high-energy-density solid-liquid hybrid battery technology in the global commercial vehicle segment, with CALB also showcasing its full "Zhiyuan" commercial battery series across multiple Chery light commercial platforms, including cargo trucks and delivery vans, at the brand’s spring launch event.

Core Technical Breakthroughs of the Mass-Produced Hybrid System

Unrivaled Safety Validation for Commercial Fleet Use Cases

Fast Charging & All-Weather Performance to Minimize Fleet Downtime

For commercial fleets, minimizing downtime is directly tied to profitability, and the new hybrid battery supports 2C supercharging technology, enabling a 30% to 80% state of charge (SOC) top-up in just 15 minutes. This rapid charging capability drastically cuts vehicle idle time during driver breaks, maximizing daily operational hours for logistics and delivery fleets.

Additionally, the system resolves a longstanding pain point for electric commercial vehicles: cold-weather performance degradation. In frigid -25°C environments, the battery retains over 20% more driving range than equivalent conventional liquid lithium-ion systems, while supporting continuous 1C discharge rates. This breakthrough eliminates the range and performance drops that have historically limited electric commercial vehicle adoption in cold regions across North America, Europe, and Northern Asia.
