Enabling Offline EV Charging With A Bluetooth Offline Solution for OCPP
EV hardware suppliers often face a critical limitation: their OCPP chargers require a stable internet connection to operate. This dependency prevents installation in offline locations like underground parking or remote areas, creating a significant barrier to market expansion and leaving a gap in service reliability for drivers.

The Outcome
The Challenge
A leading hardware supplier wanted to capture the market for locations without connectivity but found their standard open charge point protocol chargers were unusable, risking a major loss in potential revenue and market share.

Limited Market Reach

The inability to operate open charge point protocol offline made their products unsuitable for a growing number of valuable commercial and residential sites.

Inconsistent User Experience

In areas with poor connectivity, charging sessions using open charge point protocol would fail, damaging brand reputation and driver trust in their network.

The Solution
Entrans delivered a sophisticated offline open charge point protocol solution, integrating Bluetooth and a mobile app to ensure flawless operation without an active internet connection.

Result:

The supplier was able to market their chargers as "connectivity-proof," opening up new revenue streams and providing a reliable, premium user experience that competitors could not match.

Detailed Solution:

  • Bluetooth & Mobile App Integration: We developed a system where open charge point protocol chargers communicate directly with the driver's smartphone via Bluetooth for secure, local session authorization.
  • Secure Offline Authentication: The OCPP solution authenticates the user and authorizes the charge locally, removing the need for a real-time connection to a central server.
  • Store-and-Forward Transactions: Transaction data is stored securely on the charger and is processed automatically once connectivity is restored, ensuring no lost revenue.

Impact:

This turnkey solution allowed the supplier to immediately offer a highly-demanded feature without any internal R&D, giving them a powerful competitive advantage in the market.

Future-Proof Infrastructure:

The offline solution is designed with scalability in mind, supporting over-the-air updates and adaptable to evolving OCPP standards, ensuring the hardware remains competitive and compliant as industry requirements change without costly hardware replacements.
