EV Charging Design & Engineering
Engineering comprehensive EVSE infrastructure plan sets, structural mounting designs, and dedicated electrical load studies for Level 2 and DC Fast Charging (DCFC) networks nationwide. From our core market in Southern California to utility grids across the country, we optimize system architecture to interface seamlessly with co-located commercial solar arrays, maximizing existing service busbar capacity without grid overload.
Avoid tripping breakers and failed inspections
Deploying scalable Electric Vehicle Supply Equipment (EVSE) requires strict alignment with NEC Article 625 standards and California Electrical Code (CEC) infrastructure mandates. Our engineering team executes precise main service panelboard calculations and dynamic demand-response load management designs to prevent system distribution failures—eliminating complex local building department plan-check redlines and field installation delays across all jurisdictions.
- ✓ NEC & CEC Load Analysis – Comprehensive 12-month billing data reviews and continuous load calculation sheets to evaluate upstream transformer and switchgear capacities safely.
- ✓ Complete Plan Sets – Scalable site plans, detailed electrical single-line diagrams (SLDs), underground conduit/trenching pathways, and comprehensive equipment scheduling.
- ✓ Fleet & Public EVSE – Specialized electrical schematics tailored for commercial Level 2 clusters, workplace charging stations, industrial fleet vehicle depots, and high-kilowatt DCFC hubs nationwide.
- ✓ DER Sync & Microgrids – Intelligent engineering strategies coordinating heavy EV charging loads alongside active solar PV networks, automated energy management systems (EMS), and battery storage.
From load analysis to installation-ready plans
Site assessment
We review existing service capacity, panel space, and intended charger location.
Load calculation
We perform a detailed load study to determine if a service upgrade is necessary.
System design
We select appropriate equipment, wire sizing, and protection devices, and draft plans.
Permit package
We deliver stamped drawings, load study, and equipment list for your permit application.
Common questions about EV charging design
Do I need a panel upgrade for a Level 2 charger?
Often yes, but not always. We'll determine this based on your existing load and the charger's power requirements.
Can you design for commercial fleet charging?
Absolutely. We handle multi-port Level 2 and DC fast-charging sites, including load management and demand-response capabilities.
How long does the design take?
Typically 48–72 hours for a residential system; commercial projects vary by complexity.
Do you include utility coordination?
Yes – we can prepare the utility interconnection application for your EV charger if needed.
Nationwide EVSE Code Compliance & Grid Integration
Our electrical infrastructure plan sets are engineered to cross-examine hardware configurations against evolving regional power metrics, strict public utility constraints, and localized green building updates across the country.
Title 24 & ALMS Compliance
Engineered to execute complete compliance documentation for the rigorous 2026 CALGreen Title 24 mandates, optimizing Automated Load Management Systems (ALMS) to satisfy the 100% EV-ready/receptacle frameworks for multi-family, non-residential, and commercial parking expansions.
National Code Alignment
Precise calculation of continuous electrical loads, overcurrent protection device (OCPD) thresholds, and specialized feeder/branch circuit ampacities to support massive multi-port configurations.
Hardware Interface Architecture
Open ecosystem blueprints mapping layout criteria seamlessly for standard SAE J1772 connectors as well as the newly standardized SAE J3400 (NACS) hardware networks.
Upstream Grid Integration
Comprehensive support compiling engineering packages and processing grid-interconnection requests with major nationwide utility providers when high-kilowatt DC Fast Charging hubs necessitate complex transformer upgrades.
