Electric mobility

Monitor and manage electric vehicle charging—from one car in the garage, to a fleet.

Electric vehicles (EVs) and many EV chargers are smart individually, but they have to be managed within the overall electricity ecosystem, at sites ranging from individual homes to major commercial and industrial complexes. With Wattwatchers, you can track and report charging loads, control charging, and avoid creating unintended cost and operational burdens.

CASE STUDY

Electric vehicle (EV) charging is a major new infrastructure challenge for the electricity system, with massive growth anticipated as internal combustion engine (ICE) vehicles are phased out around the world. 

Evie Networks, headquartered in Queensland Australia, is a leading early-mover in the emerging EV charging service sector. When Evie Networks needed to remotely monitor electricity supply to its highway charging installations, it turned to Wattwatchers to supply its real-time energy IoT devices, initially for a number of tests and field pilots. 

Based on early testing, Evie Networks identified the Wattwatchers’ Auditor 3RM, a 3-channel cellular unit that comes equipped with Rogowski Coils to monitor large 3-phase circuits up to 3,000 Amps, as the solution for its requirements. 

How Wattwatchers can help

Highway chargers

R-Coil devices monitor large loads required for fast chargers.

Commercial sites

Manage EV charging within site demand peaks, constraints and budgets.

Home charging

Turn lower-cost ‘dumb’ EV chargers into smart energy solutions for households.

Industrial solutions

Coordinate and schedule charging of work fleets, such as electric forklifts.

Solar optimisation

Maximise EV savings by coordinating charging with rooftop solar availability.

Cost allocation

Anticipate emerging need to calculate reimbursements for vehicle-to-home & grid.

CASE STUDY

Rapid uptake of electric vehicles (EVs) in the United Kingdom in the commercial and industrial arena virtually always leads to power capacity issues on the host site that need to be overcome and then proactively managed. This pushed software-as-a-service company Envisij to seek out Internet of Things (IoT) devices that can act as its on-site data manager.

Wattwatchers caught Envisij’s attention with its nimble delivery of real-time, highly-granular electricity data, the addition of remote switching capabilities as well as monitoring, and easy integration with our API. Demand-side management is a core focus area for Envisij, including everything from lighting, to accommodating EV charging, to industrial machinery.

Through government grants it has won, Envisij is now incorporating Wattwatchers into smart home solutions as well as commercial and industrial use cases. Envisij promotes Wattwatchers as being ‘energy monitors that don’t cost the earth’, and bundles our solutions with its UtilitySMART and UtilitySWITCH platforms. 

Envisij has built the Auditor 6M+3SW into a number of its pilots and solutions, drawing on the cellular-communicating device’s ability to monitor up to six single-phase circuits (or two 3-phase circuits), while also remotely switching up to three circuits (single or 3-phase). Envisij also uses the Auditor 6W+3SW, the WiFi-communicating sister device to the 6M+3SW, and the monitoring-only 6M and 6W base versions.

FEATURED PRODUCT

For switching of loads and solar export control

The Auditor 6M+3SW combines all of the functionality of the flexible and reliable Auditor 6M with circuit-level switching capabilities.

Contactors are available for switching of single- or three-phase circuits, and can also be connected to other equipment, such as inverters, to remotely trigger control functions (such as solar export control).
