A compact 22kW charger for suitable three-phase sites

The NRG Charge Velox 22kW takes the compact socketed enclosure into workplace, shared-parking and other three-phase installations. It operates at up to 32A per phase on a suitable 400V supply and has an untethered Type 2 outlet. This standard version uses Wi-Fi or LAN for connected operation rather than including 4G.

Twenty-two kilowatts is a site and vehicle-dependent maximum, not a guaranteed charging rate. The electrical supply, circuit design, available capacity and vehicle's onboard AC charger must all support the intended output. A vehicle limited to a lower single-phase or three-phase AC rate will charge at that lower limit even when connected to a 22kW charge point.

Where the non-4G model makes sense

The standard 22kW unit is the appropriate connectivity choice where the charger can use a dependable site network. Wired LAN may be attractive for a managed building or workplace with planned data cabling, while Wi-Fi may be suitable where coverage has been surveyed at the mounting position.

Choose the separate 22kW 4G unit where a mobile-network route is a project requirement. Do not specify 4G merely because the site is commercial: a well-designed wired connection can be simpler to manage, and any mobile service has coverage and commercial terms that need checking.

Three current sensors for three-phase load monitoring

NRG's 22kW installation material documents three supplied grid current sensors, one for each phase. Their purpose is to give the charger/load-management arrangement visibility of the site's three-phase demand so charging can be controlled within the configured limits.

The site designer must determine the required sensor positions, wiring route, phase identification, polarity, communications arrangement and control settings. Three sensors do not mean every commercial supply is automatically suitable for 22kW charging. Existing loads, diversity, main protection and any other chargers must be included in the design.

Vehicle dwell time matters as much as headline output

A 22kW AC unit is most useful where vehicles can accept the higher AC rate and shorter replenishment time has operational value. Examples may include fleet vehicles returning between jobs, staff or visitor bays with moderate dwell time, hospitality parking and sites that want a higher-capacity socket without moving to DC charging.

For an overnight vehicle or a car limited to 7kW AC, the extra site work required for 22kW may not improve the real charging result. Compare the vehicle mix and expected dwell time before treating the higher number as the default choice.

An untethered socket for mixed users

The Type 2 socket lets each driver use an appropriate cable rather than leaving one lead attached to the wall. That can suit shared bays and mixed fleets because the cable can be replaced independently and the charger remains tidier when no vehicle is connected.

The cable must support the required phase/current arrangement if the vehicle is to use the full available rate. A single-phase cable or a vehicle with a lower onboard limit will restrict charging accordingly. Confirm cable specification and reach for the bay layout, then browse EV charging cables or obtain a project quote.

RFID, app and plug-and-charge access choices

Velox supports RFID, app and plug-and-charge operating modes. RFID is useful when access should be limited to authorised staff, residents or known drivers; two key-fob tags are documented with the unit. App mode provides supported remote and scheduling functions. Plug-and-charge removes the authorisation step for a controlled private bay.

For shared or commercial use, define the operational requirement before choosing a mode. If the project needs user reporting, public access, payment or a managed back office, obtain written confirmation of the supported service and costs rather than relying only on the presence of an app or protocol name.

PV mode on 22kW needs a configuration decision

NRG documents list optional PV monitoring using an additional current sensor. The 22kW wiring page also states that PV and a particular RS485 dynamic-load function cannot be used together on the device. That restriction must be resolved against the intended site design before solar-aware operation is promised.

Do not assume that the three supplied grid sensors also provide solar monitoring. The additional sensor, compatible control arrangement and commissioning method need to be specified separately, and the final design should be confirmed by NRG where simultaneous solar and wider load-management functions are required.

Black as standard, with four covers stocked separately

The complete charger is listed in Black. LAMPS plans to stock Anthracite Grey, Pure White, Sapphire Blue and Sage Green front fascias as independent accessories. A cover changes the visible finish only; power, phase and connectivity remain those of the 22kW non-4G charger.

Use the Velox fascia page for the four colour choices. Keep cover inventory and charger inventory separate unless LAMPS creates an explicit bundle.

Modular construction for phased projects

The passive backbox contains the main wiring and communication connection points, the electronic body engages with that base, and the fascia completes the exterior. This can help organise first-fix and final-fit stages on a commercial project while keeping the electronic unit out of the earliest wiring stage.

The modular design does not remove the need for a complete design, isolation, appropriate protection, testing and commissioning. Mounting, electrical work, CT installation and network setup must be completed by qualified and competent personnel.

Common questions

Does every EV charge at 22kW on this charger?

No. The car's onboard AC charger and the installation determine the actual rate. Many vehicles accept less than 22kW AC and will charge at their own lower limit.

What electrical supply does the Velox 22kW need?

It requires a suitable 400V three-phase supply and a circuit designed for the intended load. The site capacity and protection must be assessed before ordering.

Does the non-4G model still connect to a network?

Yes. It supports Wi-Fi and LAN, with Bluetooth used during configuration. Non-4G means it does not include the mobile-network connection found in the separate 22kW 4G unit.

How many load-monitoring sensors are supplied?

NRG's 22kW documents state that three current sensors are supplied for the three-phase grid arrangement. Their placement and configuration form part of the site design.

Can this model use a coloured fascia?

Yes, subject to final compatibility confirmation. LAMPS plans to stock Anthracite Grey, Pure White, Sapphire Blue and Sage Green Velox covers as separate accessories.
