The next generation business charger

Eichrecht-certified billing, V2G-ready hardware and automatic phase switching, in a build that feels closer to a flagship phone than an electrical box.

Eichrecht MID Class C billing

Eichrecht MID Class C billing

MID Class C metering at +/-0.5% with Eichrecht certification and a meter display visible from outside. Accurate enough for calibrated, legally compliant billing across Europe. A Volt Time 4G SIM is included, so certified sessions reach Plugchoice from the moment it powers on, no customer network needed.

V2G ready (ISO15118-20)

V2G ready (ISO15118-20)

Bidirectional-ready hardware out of the box. ISO15118-20 lets your EV power the building or the grid when your energy setup is ready, with Plug & Charge (ISO15118-2/3) today.

Automatic phase switching

Automatic phase switching

Switches between 3-phase and 1-phase charging on the fly, so solar charging keeps running at low power instead of cutting out. 3-to-1 switching via Plugchoice, with fully dynamic phase use and automatic phase balancing.

Future proof by design

Every feature picked for serious business installations, in hardware that feels more like a flagship phone than an electrical box.

Learn about smart charging

Built like a flagship

IP65 and IK10 in a 350 x 233 mm, 4 kg body. Full rated power up to 45 degrees C and no derating to 55 degrees C, where lesser chargers quietly slow down, across a -40 to +55 degrees C range. Underneath: a 4-pole mechanically interlocking relay with 10kA peak withstand and 10kV/5kA surge protection.

5-inch touchscreen

Live session and billing information on the charger itself, with configurable branding and screensaver. Drivers see what they pay, owners put their own name on the wall.

Never locked in

Ships with a Volt Time 4G SIM, online the moment it powers on. Underneath runs Plugchoice: an open REST API, an OCPP proxy to any backoffice, and 250+ platform integrations. It is OCPP-certified with back offices like Last Mile Solutions and MOBI.E, so pointing it anywhere is proven, not promised.

Explore all integrations

OCPP 2.0.1, OTA to 2.1

OCPP 1.6j and 2.0.1 today, upgradable over the air towards 2.1. Works with any CSMS and is natively paired with Plugchoice.

Safety built in

30mA AC and 6mA DC leakage detection (IEC 62955), earth fault protection, overvoltage cat III and temperature sensors on the main contacts. No external Type B RCD needed, roughly 100 euro saved per install.

Our quality and safety standards

Plugchoice Smart Charging included

Full phase-aware power management, from a single home to a whole car park. Solar balancing with automatic 3-to-1 phase switching keeps you charging on sunshine at low power. Dynamic load balancing protects the fuse, and dynamic tariff charging follows the cheapest hours. It reads your grid connection via P1/HAN/Linky, Modbus, or CT clamps, whichever suits the site.

★★★★★ 4.7 on Trustpilot

Trusted by European businesses

The charger is half the story. What keeps businesses with us is the service level behind it, and the reviews keep coming back to it.

Very well helped by Volt Time customer service. The AI chatbot in the Pluggy app worked surprisingly well, and when it couldn't help further I was forwarded to a person who helped me very quickly. 5 stars!

Answers you need

Everything you need to know, explained simply.

How does it scale on large sites?

Load management in Plugchoice. Load management runs in Plugchoice, not on the charger. Dynamic load balancing shares the available power across every bay on the site and protects the main fuse, with solar balancing and dynamic-tariff charging on top.

No cap per site. A single site scales to as many chargers as you need, with no maximum, all managed from Plugchoice or any OCPP backend.

What does Eichrecht MID Class C billing mean?

Calibrated to +/-0.5%. MID Class C is more accurate than the common Class B, and Eichrecht certification meets the strict German calibration-law requirements for billing by the kWh.

Visible meter display. The meter reading is visible from outside the unit, which regulated public and workplace billing schemes require.

Is it really V2G ready?

ISO15118-20 onboard. It ships with ISO15118-20 hardware for bidirectional charging, ready for V2H and V2G once your car supports discharging and the combination is certified and approved for grid feed-in in your country. TPM-backed security is built in.

Plug & Charge today. ISO15118-2/3 Plug & Charge works now - drive up, plug in, and billing is handled securely without tapping a card.

How tough is it, and how does it install?

IP65, IK10, -40 degrees C. Rated IP65 and IK10 and tested from -40 degrees C to +55 degrees C, with temperature sensors on all main contacts and anti-theft detection with a permanent cable lock.

Clean install. A backplate with a screw terminal block (typically 6 mm2 for 32A) and rear cable entry. TN, TT and IT grids are supported.

How does it connect and stay updated?

OCPP 1.6j and 2.0.1. Speaks both OCPP 1.6j and 2.0.1, plus a REST API via Plugchoice, so it works with modern backoffices and is ready for what comes next.

Always online. Wi-Fi 2.4/5GHz, Cat4 4G with a 10-year SIM, RJ45 and RS485. Connected to Plugchoice even without customer Wi-Fi.
