In the future, electric cars will become active participants in a decentralized energy system. To achieve this, we are making all charging and discharging processes traceable down to the specific facility.
Together with corporate partners and start-ups, we developed a distributed ledger-based billing infrastructure for electric vehicle charging at the Digital Hub Mobility. We use hardware-secured digital identities and a blockchain infrastructure for this purpose. This enables cross-system, unique, and tamper-proof accounting of charging processes, including the labeling of locally generated solar power. This facilitates the integration of e-mobility into the electricity market and simplifies sustainability reporting for fleet managers.

The challenge of market-based emission accounting for charging

Green electricity contracts consist of electricity and renewable energy certificates bought separately.
Public and private charge point operators often advertise the supply of 100% green electricity. Because they are the „end consumer“ as defined by §42 EnGW, they do not share auditable proof with downstream stakeholders.
Today, fleet operators and car manufacturers either use the residual mix or resort to buying GOs themselves in order to reduce market-based emissions for their fleets.
In the future, fleet operators and car manufacturers could incentivize charge point operators to procure green electricity and to provide auditable proof by covering a part of the cost of GOs.
