Challenge

75-passenger capacity busses with ramps enabling entry of wheelchair-bound passengers and prams, USB portals and smart temperature management made their way to Solaris’ ‘headquarters’ - Bilbao. Heliox was approached to provide charging solutions which would mark the company’s first footprints in Spain and the Mediterranean region. 


Solution

Heliox’s first project in Spain and first cooperation with Solaris, one of Europe’s leading bus and trolleybus manufacturers, would have Heliox provide the depot charging infrastructure, ensuring interoperability between the charging infrastructure and e-bus.

To ensure smooth installation and problem-free operations, testing was also carried out at Solaris’ factory in Bolechowo, Poland. Close cooperation between Heliox and Solaris at this phase ensured seamless implementation in Bilbao. 

Busses were charged at strategic locations in the city via CCS. A total of four 2 x 30 kW chargers were installed in Bilbao, each with dynamic functionality that allows 60 kW to be supplied to one outlet. Additionally, a Service Level Agreement meant the chargers were monitored and serviced for optimized charging at all times.

Results

Close cooperation ensured a thorough understanding of the client’s requirements and seamless installation and operations.

Project Description

Heliox and TU/e ​​aim to develop an integrated solution that makes charging heavy electric vehicles accessible without negative consequences for local electricity networks. Together, we want to achieve this by developing and demonstrating a new, multiple and dynamic charging system for heavy electric vehicles that is equipped with software-controlled stabilization to absorb disturbances on the local energy grid.

The intended system will consist of a dynamically configurable charging system based on modules that can be connected in parallel, each with three 60 kW outputs. With this they want to be able to distribute the loading capacity dynamically over several vehicles. The charging system can therefore be used for opportunity charging up to 360 kW for a single vehicle as well as for regular charging of several vehicles.

In addition, smart software and a microcontroller board are being developed. The converter of the charging system can be used via this software to compensate for grid disturbances. The disturbances are neutralized via a low impedance path. This allows losses on the grid to be converted into usable energy, while improving the voltage quality of the grid. In fact, the system completely takes over the function of current power filters on the basis of smart control.
