It makes a good deal of sense to us, to roll out passenger commuter trains first before tackling heavier goods trains. The shipping industry is following a similar logic, as are passenger electric car manufacturers too. We were pleased to receive news of next gen train batteries under development, this time for a leading train manufacturer.
New Smaller Batteries for Next Generation Trains
The Hitachi press release we link to below, explains the project is a joint venture between University of Birmingham England, Innovate UK, and DB ESG rolling stock engineers. The broader project goals, which support UK innovation and skills are threefold, namely:
- Develop new next gen train batteries for Hitachi intercity and commuter routes.
- These should be 40% smaller than currently, but with 22% greater energy density.
- Reduce emissions and operating costs, while delivering more inclusive services.
This public-private partnership will complement a pioneering intercity program, currently on trial in Northern England and Scotland.
More About This New Next Generation Battery
Railway News website explains how lithium-iron phosphate (LFP) chemistry will deliver the smaller size with greater density. These new generation LFP batteries will use lithium iron phosphate as their cathode, teamed with a graphitic carbon anode electrode with a metallic backing.
A smaller battery, which does not compromise power requirements, takes less space under a carriage floor. This means the height of the floor itself can be lowered, facilitating easier access for passengers with disabilities.
Meanwhile the smaller batteries will also reduce overall train weight, height, and wind resistance too. This in turn will increase operational efficiency, and simplify maintenance according to Railway News.
“Continuous improvement means that we are always working on the next generation of smaller and more powerful batteries,” remarks the Chief Technology Officer at Hitatchi Rail. Next gen train batteries are helping them reduce railway costs, and even remove diesel engines entirely, so batteries can come into their own.
