Recording of Thursday, May 08, 2025 | The smarter E Europe Exhibition Program 2025 | Exhibition Program | Language: English | Duration: 2:11 .
Dr. Jan Figgener, a visiting scientist at RWTH Aachen University, introduces a session on bidirectional charging and storage solutions for homes and industries. The concept of bidirectional charging was first introduced in the 1990s but has only recently gained momentum with technological advancements. Presently, there are market-available bidirectional wall boxes and vehicles like the Renault 5 in France that work alongside Mobility House to facilitate smart charging systems. Utrecht plans to install 400 such stations over two years while Denmark integrates 600 megawatts into its frequency restoration market unidirectionally; meanwhile, a UK company boasts access to 1.3 gigawatts of charger power. Dr. Figgener highlights upcoming presentations from leading manufacturers in stationary home and industrial storage markets without direct participation from car manufacturers despite their significant role—cars remain idle about 95% of the time with an average battery capacity six times larger than typical home systems (60 kWh vs. approximately10 kWh), suggesting minimal degradation through shallow cycling usage patterns.

Bidirectional charging and vehicle-to-grid (V2G) technology in particular use the storage capacities of vehicle batteries to make our energy system more flexible, efficient and cost-effective. So do we still need home storage systems at all? In this session, the leading manufacturers of home storage systems will take a stand on the topic.
