PIERRE Pro - EV Charger 22kW Three Phase (6-32A) - PREORDER

1. Product Description

Three-phase AC EV charger with 22 kW nominal output, adjustable current (6–32 A), OCPP 1.6 compatibility, and multi-level protection features. Designed for fixed installation in residential and commercial settings, with Type 2 and GB/T connectors.

The EV Charger is monitored and controlled from the Smart PIERRE app. The charger communicates with the PIERRE cloud over OCPP 1.6 (Open Charge Point Protocol), which provides remote management, status monitoring and charging session control.

The integration enables features such as:

Remote start and stop of charging sessions.
Real-time charger status monitoring.
Charging session history and energy consumption statistics.
User authentication and access management.
Automation with other PIERRE devices and building functions.

Charging Modes

The EV Charger supports two operating modes.

Plug & Play Mode

In Plug & Play mode, charging starts automatically as soon as the vehicle is connected to the charger. No user authentication is required. Use this mode only where access to the charger is physically restricted to authorized users.

Authorization Mode

In Authorization mode, users must authenticate before a charging session can begin. Authentication is performed with an RFID card, so only authorized users can start a session. This mode is recommended for apartment buildings, workplaces, hotels, public parking areas, and other shared charging locations where access control and user identification are required.

Electrical Installation Requirements

An EV charger is a high-power electrical device and must be installed according to local electrical regulations by a qualified electrician.

Before installation, the following requirements must be verified:

The EV charger must be connected to a dedicated electrical circuit protected by its own circuit breaker.
The protective devices (circuit breaker and residual current protection, where required) must be selected according to the charger's rated power and local electrical standards.
The electrical wiring must have the appropriate cable cross-section for the expected charging current.
The installer must verify that the building's electrical installation and the available power capacity are sufficient to support the charger without overloading the electrical network.
If multiple EV chargers or other high-power consumers are installed, load balancing or power management should be considered.

Safety Notice

Improper installation may result in overheating, equipment damage, or electrical hazards. Always ensure that the electrical installation complies with local regulations and that the available electrical capacity is suitable for the selected charger and charging current. Installation and commissioning should only be performed by qualified personnel.

If you use a pacemaker or another implanted medical device, ask its manufacturer whether charging may affect it before you use the charger.

• Do not power the charger from a private generator. • Use the charger only within its operating temperature range of −30 °C to +50 °C. • Incorrect installation or testing can damage the vehicle battery or the charger. Such damage is not covered by the warranty.

3. What you need

Wired and cloud connected. Needs an internet connection for OCPP communication with the PIERRE cloud; no PIERRE Controller is required. Controlled through the Smart PIERRE app.

4. WARNING – HIGH TEMPERATURE

At ambient temperatures above 55°C, the EV charger may automatically reduce its charging power and, in certain conditions, may shut down to protect the device from overheating. Always install the charger in a cool, shaded, and well-ventilated location, protected from direct sunlight. Prolonged exposure to direct sunlight can significantly increase the charger's operating temperature and may result in reduced charging performance or temporary shutdown.

7. Before installation

Who may install the charger

Only a qualified electrician may install, operate and maintain the charger: a person with certified electrical training who knows the applicable regulations and the hazards involved.

Choosing the location

Check where the vehicle parks and where its charging port is. The 5 m cable must reach the port comfortably.
Mount the charger in a well-ventilated place, preferably in an enclosed garage on the side of the charging port.
Do not mount it in a closed box or next to hot appliances.
Mount the charger about 1.2 m above the floor.
Keep 190 mm free around it so the cable can be looped.

Tools you need

Pencil or marker
Drill and hammer
Phillips screwdriver and small flat-head screwdriver
Wire stripper and crimping pliers
Ferrules sized to the supply cable cross-section
Voltmeter or digital multimeter, to check the AC voltage at the site
Supply cable
Twisted-pair cable (max. conductor diameter 1.02 mm, max. cross-section 0.82 mm²) if you connect an energy meter for dynamic load balancing (RS485)

8. Installation

Switch off the circuit breaker before you start. Check with the multimeter that the supply cable is not live.

Step 1 – Fix the wall bracket

Hold the bracket against the wall and mark the four holes. Drill the holes to the size shown on the bracket, insert the wall plugs, then screw the bracket firmly to the wall with the four bracket screws.

Step 2 – Hang the charger body on the bracket

Hang the charger body on the bracket so the slots sit on the bracket hooks. Secure it with the base mounting screw and the under-base mounting screw.

Step 3 – Connect the supply cable

Strip the supply cable and its conductors to the lengths below. Choose the method that fits your cable entry; both are valid.

Crimp a terminal onto each conductor and connect it to the matching input terminal on the circuit board.

Single phase (7 kW): connect N-IN, L1-IN and PE-IN.
Three phase (11 kW / 22 kW): connect N-IN, L1-IN, L2-IN, L3-IN and PE-IN.

If you ever replace the charging cable, strip its conductors to: N-OUT 55 mm, L1-O 75 mm, L2-O 130 mm, L3-O 155 mm, PE-O 100 mm, CP-O 130 mm.

Step 4 – Connect dynamic load balancing (optional)

See section 7.

Step 5 – Set the charging current

See section 6.

Step 6 – Connect the upper cover

Plug the connection cable between the circuit board in the base and the circuit board in the upper cover.

Step 7 – Fit the upper cover

Place the upper cover on the base and fasten it with the six top cover screws.

Step 8 – Fit the front panel

Press the front panel onto the upper cover until all snap-fits click into place.

Removing the front panel

Release snap-fit A at the bottom, then snap-fits B on the left and right, and push the panel upwards.

9. Setting the charging current

The four DIP switches on the circuit board set the maximum charging current and two operating options.

Warning: the power must stay OFF while you change the DIP switches. Changes made with the power on are not applied, and touching the board under power can cause an electric shock.

Switch off the circuit breaker.
Move the switches with a non-conductive tool.

DIP switch settings:

Charging current (DIP1, DIP2)

Ground detection (DIP3)

Control mode (DIP4)

10. Power-on check

Before you switch the charger on for the first time, check the following.

There is enough space around the charger for use, service and maintenance.
The supply line has the correct circuit breaker and residual current device for the charger's rated current.
The charger is mounted and wired correctly, and all covers are closed.
Nothing is left on top of the charger.

Switch on the circuit breaker. The LED runs a self-check (blue, green and red flash alternately) and then shows a steady blue light: the charger is in standby.

If the LED shows red, unplug the vehicle, switch the charger off at the circuit breaker, wait 30 seconds and switch it on again. If the fault remains, contact your PIERRE partner.

12. Charging

Connect the vehicle

Make sure the LED shows steady blue (standby).
Plug the Type 2 connector into the vehicle's charging port and check that it sits firmly.
The LED flashes green for about one second and then goes off: the charger is ready.

Start charging

Hold your RFID card against the card reader on the front panel, or start the session in the app. The LED turns steady green and charging begins.

Stop charging

Charging stops automatically when the battery is full. To stop earlier, hold your RFID card against the reader again or stop the session in the app. Wait until the LED returns to blue, then unplug the connector from the vehicle and hang the cable on the charger.
