HeyCharge Offline EV Charging and CPMS

HeyCharge GmbH is a company registered in Munich, Germany, that develops EV charging based on offline Bluetooth authentication. It targets residential and commercial buildings, such as underground garages, where network connectivity is poor or costly, and which therefore struggle to deploy conventional charging.

The offer combines hardware (the HW18 wallbox, retrofit adapters and an edge gateway) with a charge point management system, a driver app and an SDK/API for white-label use. Session data syncs to the cloud when connectivity returns. The site lists real estate customers such as Vonovia and Patrizia and backers including Y Combinator and BMW i Ventures.

• Offline authentication: Bluetooth access with patented cryptographic protocols and later cloud sync.
• Retrofit hardware: Connect MagicBox and Connect Bridge adapt OCPP chargers to the platform.
• Edge gateway: Multi-charger site gateway with dynamic load management.
• CPMS: Site management and billing via Stripe.
• Offline roaming: EMP card sessions settled through Hubject.
• SDK and API: White-label integration, including Android Automotive OS.

Apartment buildings can equip basement parking with chargers that work without network coverage. Office towers can add paid charging for tenants. Developers can pre-wire parking spaces and activate chargers later.

Chargers work in basements and garages without SIM cards, network infrastructure or connectivity fees. The company claims 40-70% lower total cost of ownership. Existing OCPP wallboxes can be retrofitted, and offline roaming settles through Hubject, so drivers can use existing EMP cards.

High-rise apartments and basement car parks are common in Vietnamese cities and the government is pushing charging in residential complexes. Offline-capable charging addresses poor connectivity in such sites and lowers installation cost.

HeyCharge GmbH is registered in Munich, Germany (imprint). Backers listed on the site include the European Innovation Council, Y Combinator, BMW i Ventures and Vireo Ventures. The HW18 wallbox is Eichrecht-certified.
