According to the latest report from Chongqing Feilong Jiangli，Volvo Bus participated in a research and development project to use used bus batteries as solar energy storage devices. At present, the waste batteries of Gothenburg 55 electric bus in Sweden are used for solar energy storage devices.

With the progress of urban traffic electrification transformation, the recycling of waste batteries has become a key issue.

The project is based at Riksbyggen's Viva Housing Cooperative in Gothenburg, an apartment complex designed to make it the most innovative and sustainable residential project in Sweden.

To this end, Riksbyggen, Volvo, Gteborg Energi and Yorkshire Science Park have jointly created a system to collect energy from solar panels on the top floor of apartments and store them in used batteries used earlier by No. 55 electric buses.

The battery warehouse system consists of 14 lithium batteries for used buses. Researchers installed it in a battery chamber to create a 200 kWh battery pack. The equipment can meet the majority of the electricity demand of apartment residents and output the stored electricity to them.

The device aims to reduce peak hours of electricity consumption, use used batteries to store solar energy or sell surplus solar energy. The equipment can also be used to purchase and store the power of the State Grid, thereby enhancing the energy efficiency of Viva free energy system and improving the operation status of the city's power grid.

The project is supported by the European Union project IRIS Smart Cities, a Light House project funded by EU HORIZON 2020.
