UK: The project, implemented in the country, is aimed to develop LiFePO4 battery that is 40% smaller and 22% lighter.
Such batteries are important for low-floor trains because the undercar space where these power sources are located is limited. Hitachi Rail also expects that reducing the weight of batteries would lead to a reduction in the weight of rolling stock, making maintenance and refurbishment easier.
The €1.7 mln R&D will involve UK research centres and battery supplier Turntide Technologies. The project is part-funded by Innovate UK.
Hitachi Rail is not giving a timeframe for the project, but the batteries could be in demand now. For example, a five-car Class 802 hybrid train powered by batteries and diesel fuel is being tested in the country.
LiFePO4 batteries are distinguished from other lithium-ion batteries by their longer service life, faster charging and other advantages. They are widely used in wheeled public transport, and are also used in locomotives and other rail vehicles, such as those produced by CRRC.
