Smart energy system supports EV charging


Battery manufacturer, GS Yuasa will supply its dual chemical battery technology to a Port Energy Systems Optimisation (PESO) project in Portsmouth.

The project will provide power for electric vehicle charging and localised grid support and will be piloted at Portsmouth International Port. It will include a dual chemical (lead acid and lithium-ion) hybrid energy storage system. A big problem for rapid charging of electric vehicles (EVs) is the limited power available to many commercial premises. This will often be in the 30-50kW range for a medium sized building. The battery capacity of standard EVs range from 50kWh to 90kWh, so fast charging can overwhelm sites causing the grids to crash. GS Yuasa’s containerised solution avoids the need for expensive excavations and relabelling from the grid, reducing the project cost and environmental impact.
The new dual chemical energy storage system will be able to supply 100kW of power. The system will allow electric vehicles to be fast charged during the day from electricity supplied overnight at a lower tariff.

Mike Sellers, port director at Portsmouth International Port said, “We’ve previously said we’ll take bold action to meet our goal to be the UK’s first zero emission port. This innovative project demonstrates that we want to be at the forefront of research into sustainable energy initiatives that will help us reach that target.
“GS Yuasa’s battery will provide the centrepiece of the project which will help us use renewable energy more efficiently across the port estate.”

PESO is a two-year project co-funded by Innovate UK. There are three main areas of innovation to the pilot, the first is the construction of the dual chemical battery system, designed by GS Yuasa. The second is advanced management software which will optimise onsite energy generation. The third area will be the development of smart port grid infrastructure. All three areas will play a significant part in the port’s goal to be carbon neutral by 2030.

Mark Greer, general sales manager – Reserve & Renewable Power Division at GS Yuasa Battery Sales UK said, “As the need to move towards greener energy products increases, we’re delighted to introduce a viable and easily-integrable solution.”
GS Yuasa also offer a fully lithium energy storage system for maximum capacity and capability.
