How can a dedicated-line freight transportation system solve a battery degradation problem?

Based on a realistic dedicated-line freight transportation scenario, a modeling framework that incorporates the daily operation of the ET fleet and the long-term battery degradation is developed, which decides on the optimal configuration of the BSS. Then a tractable solution procedure is proposed to efficiently and globally solve the problem.

What is a battery product development facility?

Based in Coventry, the publicly-funded battery product development facility welcomes manufacturers, entrepreneurs, researchers and educators, and can be accessed by any organisation with existing or new battery technology – if that technology will bring green jobs and prosperity to the UK.

Are battery swapping stations effective for electric trucks?

Battery swapping stations (BSSs) have been gradually adopted in reality for electric trucks (ETs) to improve their operational efficiency. This study focuses on the optimal design of a BSS system that exclusively serves an ET fleet offering dedicated-line transportation services.

How do et batteries work?

ETs run continuously at constant and homogeneous speeds when they are not exchanging their batteries in the BSS during daily operating hours. At the beginning of the daily operation, each ET is equipped with a battery at a predetermined SOC level, i.e., S O C u as introduced below.

Can battery swapping stations reduce battery degradation cost?

The battery degradation effect and nonlinear charging profile are incorporated. A battery charging management strategy is proposed to reduce the degradation cost. Battery swapping stations (BSSs) have been gradually adopted in reality for electric trucks (ETs) to improve their operational efficiency.

Do et batteries need a smaller size?

Accordingly, batteries with a smaller size are needed. And the optimal numbers of batteries and chargers are subject to the requirement of operation of the ETs, which cannot be reduced. Overall, the benchmark results of the infrastructure configuration are relatively stable when the unit battery cost changes.
