Electrified fleets and high-traffic public sites fail on infrastructure, not vehicles. The decisive variables are connected: available service capacity, demand-charge structure, charger utilization, and software-driven uptime. OmniYield engineers charging deployments as integrated power systems—not a row of pedestals—so throughput scales without triggering a costly service upgrade.
Power architecture & demand-charge mitigation
Demand charges, billed on peak kW draw, routinely account for 40-70% of a charging site's electricity cost. A single uncontrolled 350kW dispenser can reset a facility's monthly peak in seconds. We model 15-minute interval demand windows against your tariff and deploy dynamic load management (DLM) to cap aggregate draw, plus optional battery buffering to shave peaks and arbitrage time-of-use rates.
Charger selection follows the duty cycle, not the spec sheet. Depot fleets that dwell overnight are best served by 19.2kW AC or right-sized 60-120kW DC with power sharing; corridor and public sites justify 150-350kW DC liquid-cooled dispensers delivering 10-80% on an 800V architecture in under 20 minutes.
Networking, interoperability & uptime
Every asset we commission speaks OCPP 2.0.1 to the back office and supports ISO 15118 plug-and-charge, preventing vendor lock-in and enabling smart-charging schedules, dynamic pricing, and remote diagnostics. Hardware-agnostic networking means a failed unit is swapped without re-platforming the site.
- Dynamic load management capping aggregate site draw to protect service capacity
- OCPP 2.0.1 back-office integration with ISO 15118 plug-and-charge
- Optional DC-coupled battery buffer for demand-charge shaving and resilience
- Liquid-cooled CCS/NACS dispensers rated to 500A continuous
- 24/7 network operations center with remote reboot and predictive fault alerts
Operations, reliability & return
Reliability is the entire value proposition: a stranded driver at a broken charger is a churned customer. Our 99.2% uptime SLA is enforced through redundant payment paths, predictive maintenance on contactors and coolant loops, and a managed spares program. We instrument every session and surface utilization, energy throughput in MWh, and revenue per port.
On the economics, we underwrite each site against utilization curves, blended energy cost, and applicable incentives, then report projected IRR and payback. Commercial depot deployments typically reach payback in 4-7 years once demand charges are controlled and make-ready credits are stacked against capital expenditure.
