EVduty product in development: EVCCS200 external current sensor
Constantly in search of efficient and affordable solutions, the Elmec engineering team is designing an external current sensor. This device will make it possible to install an EVduty charging station without having to increase the electrical panel amperage capacity. Another context of use is when an electrical panel is located in a unit within a multi-dwelling building while the electricity meter is elsewhere, in the basement for example.
Operation
This product consists of a smart current sensor that transmits its data over the local network via Ethernet or WiFi to one or more EVduty EVC30 smart charging stations connected to the same local network. The charging stations can thus reduce their maximum charging current so that the total current consumption (from the charging stations and other devices in the building) remains below the protection circuit breaker’s limit. Only charging stations from the EVduty brand can “communicate” with the current sensor via a configuration with the EVduty mobile application.
Use # 1: LIMITED ELECTRICAL PANEL
For an existing electrical panel that does not allow the addition of a 30A electrical load such as a charging station.
Installation:
- Install the external current sensor on the output of a circuit breaker that protects equipment that has a similar or equivalent electrical load and install a 40A circuit breaker for the EVduty EVC30 charging station.
- Configure the sensor and charging station so they are connected on the same local network and “communication” between the two devices is possible.
- If the selected equivalent equipment is in use, only the remaining current portion will be available for charging with the EVduty EVC30 charging station. Ex: If the stove consumes 12A and is protected by a 40A circuit breaker, the current available for the charging station will be (40A x 80%) – 12A = 20A.
Use #2: MULTI-DWELLING BUILDING
For a multi-dwelling building situation where electricity meters are in the basement while electrical panels are located in each individual unit. An individual unit’s owner wants to install a charging station and wants the electricity consumed to come from the electricity meter supplying the unit in order to pay for the electricity consumption related to vehicle charging in the electricity bill.
Installation:
- Install a 40A electrical panel on the 125A branch circuit between the electricity meter and the individual unit’s main electrical panel.
- Install a 40A circuit breaker in this sub-panel for the EVduty EVC30 charging station.
- Install the current sensors on the main 125A cable to measure the current consumed by the individual unit and sub-panel for the charging station.
- Configure the sensor and charging station so they are connected on the same local network and “communication” between the two devices is possible.
- If the individual unit consumes electricity, only the remaining current portion will be available for charging with the EVduty EVC30 charging station. Ex: if the individual unit consumes 80A and is protected by a 125A circuit breaker, the current available for the charging station will be (125A x 80%) – 80A = 20A.
Features
Here are some technical details for the EVCCS200 EVduty external current sensor currently under development at Elmec:
- Current measuring range between 0 – 200A
- Ethernet and WiFi communication over LAN
- Equipped with a failure detection system of current measurements
- Configuration of the type of circuit breaker to be protected
- Ability to manage the system with a mobile device or computer
- 120VAC power supply
- Possibility to have multiple EVCCS200 current sensors on the same local network
Availability
Available soon online through the EVduty store or from an authorized EVduty representative, the EVCCS200 external current sensor will typically be sold together with an EVduty EVC30 smart charging station. EVduty EVC30 charging station owners will also be able to purchase the device alone. In order to pair the sensor with an EVduty EVC30 charging station, the station must be a smart version (Smart-Home or Smart-Pro). Note that standard EVduty EVC30 charging stations (non-smart versions) can easily be upgraded remotely.
Price
Since product development is in progress, it is not yet possible to announce a price. It will be announced once the sensor’s marketing begins.

Please note that this device must be installed by a master electrician.
