Clean Energy Global GmbH from Berlin is developing a global, licensable standard for smart swappable battery packs to enable its B2B clients to offer Battery-as-a-Service (BaaS) to make the energy transition a success. Clean Energy Pack (CEP) is the only modular scalable, swappable and smart battery system with open IoT gateway Clean Energy Link (CEL) for stationary and e-mobility use. Controlling, steering and invoicing is done via energy cloud Clean Energy Net (CEN), available as a white-label solution, mainly for licensing as an ecosystem.
