The Challenge
An industrial park carpark in Ethiopia wanted to introduce EV charging as a new tenant and visitor amenity—and as an additional revenue stream. The asset had open parking bays and an existing electrical supply, but several constraints:
- Limited bay footprint — floor-mounted 120–360kW DC units would have been oversized for the site’s initial throughput and physical layout.
- Need for revenue logic — simply providing power was not enough; the park needed session billing, payment acceptance, and public discoverability.
- Operational visibility — with multiple bays, the operator needed centralized monitoring of charger status, energy consumption, and electrical parameters.
The operator was looking for a wall-mountable 40kW-class DC charger that could act as a commercial-grade, revenue-ready charging point.
The Max Power Solution
We deployed 40kW OC Series wall-mounted DC single-gun chargers across the park’s parking inventory, configured for a public-facing commercial environment:
- 40kW DC single-gun output — a practical fast-charge tier per bay, balancing charging speed with manageable draw on the site’s electrical supply.
- Wall-mounted unit with floor pedestal/column — the OC Series’ wall-mount design was paired with a column/pedestal so each open-lot bay could host its own charger at the vehicle, without sacrificing the compact footprint.
- Type-A RCD + OCPP 1.6J — Type-A RCD provides AC residual-current protection for the commercial installation; OCPP 1.6J connects each charger to the operator’s cloud management platform.
- Cloud platform integration — the operator monitors online status, charging power, current and voltage parameters in real time, and can remotely control charging sessions and receive automatic fault reports.
- Smart power distribution — OCPP smart charging allocates the site’s available capacity across active chargers, protecting the shared transformer as the bay count grows.
- Online payment tools + map-APP integration — chargers are listed and discoverable through map applications, and sessions support online payment, converting a static parking bay into a billable charging asset.
The Results
- New revenue stream — previously unused parking bays became paid, discoverable charging points accessible through map apps and online payment.
- Centralized operations — the cloud dashboard gave the park operator real-time visibility into every charger, without on-site patrols.
- Scalable bay model — wall-mounted 40kW units can be added bay-by-bay as demand grows, matching capex to actual utilization.
- Tenant & visitor amenity — the park enhanced its offering to EV-owning tenants and visitors, supporting broader EV adoption in the region.
Key Takeaways for Commercial Parking Operators
- Match charger class to bay throughput. 40kW wall-mounted DC is the right commercial tier when bays are small-to-mid volume and floor cabinets are overkill.
- Revenue requires software. OCPP + online payments + map integration is what turns a charger from an amenity into an income line.
- Visibility reduces OPEX. Cloud monitoring and remote fault reporting replace truck rolls with proactive maintenance.
- Smart charging protects shared capacity. OCPP load management lets a site scale bay-by-bay without immediately upgrading the transformer.
