Global testing and certification for Electric Vehicle Energy Management Systems (EVEMS)
Electric Vehicle Energy Management Systems (EVEMS) must meet rigorous functional safety and performance standards to be permitted under the Canadian Electrical Code and the US National Electrical Code. As a Nationally Recognized Testing Laboratory (NRTL) accredited by the Occupational Safety and Health Administration (OSHA) in the US, a Testing Organization and Certification Body accredited by the Standards Council of Canada (SCC), and an IECEE CB-Scheme National Certification Body (NCB), Intertek provides end-to-end testing and certification services for EVEMS manufacturers.
From line-side switching controllers and dynamic load management systems to multi-tier EVEMS for large fleets and multi-unit residential buildings, Intertek's global network helps manufacturers achieve certification with precision, pace and passion.
What is an Electric Vehicle Energy Management System (EVEMS)?
EVEMS actively provide a means used to control electric vehicle supply equipment loads through the process of connecting, disconnecting, increasing, or reducing electric power to the loads. This allows building owners and electrical contractors to apply a demand factor when calculating EV charging loads under the Canadian Electrical Code (CSA C22.1) and the NEC (NFPA 70).
The result? More EV chargers can be installed on existing electrical services – often avoiding costly panel, feeder, or service upgrades.
Comprehensive EV Energy Management System (EVEMS) Capabilities
Intertek tests and certifies the full range of EVEMS configurations:
- Line-Side Switching EVEMS – Controls power by switching supply conductors on and off. Simple, fixed-quota systems ideal for residential and small commercial applications.
- Dynamic EVEMS – Uses real-time communication to vary charging rates based on live current monitoring. Perfect for multi-station residential and fleet installations.
- Multi-Tier EVEMS – Manages load at multiple levels (branch, feeder, service) simultaneously. Built for large MURBs, commercial fleets, and campus environments.
- Life-Safety System Integration – Safely uses unused capacity of fire pumps, smoke control fans, and other life-safety circuits with dedicated monitoring and immediate safe-state response.
- Base & Swing Mode Configurations – Allows multiple EVEMS to coexist on the same circuit without hunting or oscillation. One system acts as base (fixed quota), another as swing (dynamic quota).
- Role-Based Access Control (RBAC) – Three levels of access: Standard (safety configuration), Assembly (safety execution), and Administration (password resets, software updates). Physical security requires tool-accessible covers for safety settings.

Electric Vehicle Energy Management Systems (EVEMS) - Frequently Asked Questions (FAQs)
EVSE (CSA C22.2 No. 280/UL 2594 and CSA C22.2 No. 346/UL 2202) is the charging station – the equipment that delivers power to the vehicle. EVEMS (CSA/ANSI C22.2 No. 343) is the energy management system that controls, monitors, and limits power delivery to EVSE to prevent overloads. The two standards are complementary and explicitly exclude each other.
- Yes – if your product actively controls EV charging loads to allow a demand factor in load calculations (load management controller, smart panel, software-based power allocation system).
- No – if your product is a standalone EVSE. You need CSA C22.2 No. 280/UL 2594 (AC) and CSA C22.2 No. 346/UL 2202 (DC) instead.
- Class B Response time – ≤5 seconds for circuits ≤60A; ≤10 seconds for larger circuits or single-enclosure systems.
- Loss of communication – System must revert to pre-defined safe state within response time.
- Current monitoring – CT/VT connections must be monitored for disconnection or out-of-range readings.
- Pre-defined safe state – Must generate an abnormal condition signal and log the cause when activated.
No. CSA C22.2 No. 343 is already approved as an American National Standard (ANSI). It references the US National Electrical Code (NFPA 70) and is recognized for installations across the United States. A single certification to CSA/ANSI C22.2 No. 343 provides North American market access – no separate US standard is required.
- The product must be marked "EVEMS" (Clause 6.2).
- Conductor temperature markings are required if terminal temperatures exceed 60°C.
- Configuration labels must indicate quotas, circuit identifiers, and warnings.
- Instructions must be bilingual (English/French) for Canada.
- An installation checklist must be provided to demonstrate correct configuration to the AHJ.
Absolutely. Intertek offers pre-compliance evaluations, design reviews, and advisory services to identify issues early. This minimizes costly redesigns and accelerates market access.
