CATL, the world's largest manufacturer of batteries for electric vehicles, has released a new technology—an ultra-fast charging battery with an 8C rating designed for light commercial electric vehicles.
New Battery Characteristics
This battery is designed to charge from 20% to 80% in less than seven minutes, and a full charge cycle takes less than nine minutes. According to the company, this could significantly reduce downtime for delivery fleets and bring the convenience of electric vans closer to the refueling speed of diesel fuel.

Advantages of 8C Technology
The main feature is its ability to charge at an 8C rate. Simply put, the C-rate indicates how quickly a battery can accept a charge relative to its capacity. A higher rate allows the battery to absorb energy much faster, provided the vehicle and charging station are compatible.
According to CATL statements, charging from 20% to 80% takes only 6 minutes and 48 seconds, and a full charge takes less than nine minutes. If these figures are confirmed in real operating conditions, fleet operators will spend much less time waiting at charging stations.
Maintaining Longevity During Fast Charging
Fast charging often raises concerns about overheating and the long-term health of the battery. CATL claims to have solved these issues by reducing the battery's internal resistance by approximately half compared to the industry average, which promotes more efficient heat management during intensive charging.
Furthermore, the company has reengineered the graphite interface at the atomic level to reduce lithium loss, which slows down battery degradation over time. Because of this, CATL offers warranties of up to 10 years or 1,000,000 km, making the product attractive to businesses operating high-mileage commercial vehicles.
Performance in Cold Climates
Extreme temperatures can seriously slow down the charging process of electric vehicles, creating difficulties for fleets operating in cold regions. CATL states that the new battery increases charging time by only about 2 minutes and 30 seconds at minus 20°C compared to room temperature.
This improvement was made possible by self-heating technology, which was previously implemented in the Shenxing battery platform, allowing for high charging speeds even in severe cold.
Development of Charging Infrastructure
However, having a fast battery is not enough without corresponding charging infrastructure. To support adoption, CATL plans to install about 4,000 integrated ultra-fast charging stations and battery swap stations in nearly 190 Chinese cities by 2026.
These facilities are intended to serve both passenger cars and light commercial fleets, making high-speed charging more practical for daily operations.
Significance for Logistics
For companies involved in delivery and fleet management, every minute a vehicle spends charging means lost travel time. If the characteristics claimed by CATL prove reliable in daily use, the Tianxing II battery can increase vehicle utilization, simplify route planning, and reduce concerns about battery lifespan.
Combined with the expanding network of charging stations, this technology has the potential to accelerate the adoption of electric vehicles in commercial logistics, bringing electric operation closer to the speed and efficiency of diesel fleets.
