Pico EV Charger

Pico is a MID-certified charging station with an integrated mobile network and WiFi interface for transmitting real-time data. The charging station synchronises the measured values automatically and encrypted to the smart-me Cloud. The station can be integrated into the eCarUp backend and offers static and dynamic load management. The data can be exported to third-party systems and processed further in the smart-me Portal or via our open interface.

Key installation notes at a glance

• Pico has phase switching - please connect all phases according to the labelling (L1 = L1, L2 = L2, L3 = L3)

Function descriptions

ISO 15118 communication standard (Plug&Charge, V2H, V2G)

What kind of standard is this?

The ISO15118 standard is a communication standard between vehicle and charging station. It describes the physical requirements and protocols as well as the supported functions of this interface.

The functions primarily include:

• Charging authorisation for Plug & Charge

• Charge management for charging and discharging vehicles (unidirectional charging, bidirectional charging for V2H and V2G)

What is the goal of the standard? The goal of this standard is a homogeneous integration of the vehicle and its storage into the public grid or into the home system as a storage unit. In the long term, the vehicle storage should be usable to stabilise the public grid (V2G = Vehicle to Grid) or as a home storage solution (V2H = Vehicle to Home).

Is this already a reality?

The use of this standard is still very limited. Various charging hardware and vehicle manufacturers are currently carrying out tests on this topic in order to align and further develop the communication. Plug & Charge solutions are in some cases already in operation in real life, but are not yet particularly widespread.

V2G and V2H applications are already partly supported today by DC charging stations. The offering for V2G and V2H on the AC charging station side is currently still very limited or non-existent, because the necessary equipment is not available on the vehicle side.

However, the first vehicle manufacturers have already announced vehicles that will have the technical equipment. At present, however, none of these vehicles can be purchased on the market. (As of 16.05.2025)

What does this mean for your Pico charging station?

Your Pico charging station is fully prepared for the future. A software update will be sufficient to unlock the functions on your Pico. We are currently working intensively on implementing the functionalities.

RCD / DC fault detection and load protection

The integrated safety devices check their functionality fully automatically.

• At least every 24 hours since the last check.

• Whenever the device is restarted.

If an error occurs during the self-checks, no power will be released and the information will be shown on the display. If an error occurs during the charging session, the power is interrupted and the error is shown on the display.

The error can only be reset mechanically by unplugging and plugging the charging cable back into the charging station.

Display

The behaviour of the display is described on the page Pico display

Pico connections and dimensions

Connection diagram

L1: Phase 1

L2: Phase 2

L3: Phase 3

N: Neutral conductor

PE: Protective earth conductor

The protective earth conductor should be attached to the upper connection screw so that the stand is earthed directly together with the station.

Caution: The product can only be operated in 3-phase star connection or single-phase!

Cable routing

With Pico, the cables can be routed in and out at 5 points.

Two at the top, two at the bottom and one through the back plate.

For routing through the back plate, a hole with a diameter of 25-26mm must be drilled.

Details on stand assembly can be found in the assembly instructions in the downloads.

Load shedding (external inputs)

Pico load shedding

Load shedding can also be implemented with only one available signal.

For the configuration from no charging to maximum charging power, the signal is wired to IN1 and IN2 as well as COM. For the configuration from 6A minimum power to maximum charging power, the signal only needs to be wired to IN2 and COM.

COM is the neutral conductor; IN1 and IN2 must be supplied with a voltage for the ON signal. IN1 and IN2 do not generate any voltage; it must be provided externally.

Caution: Load shedding can be wired either to all Picos or, at a minimum, to one in each load group. This function is also guaranteed without an internet connection.

Alternatively, load shedding can also be carried out via multilevel load management using meter input signals.

Safety instructions

The safety instructions must be observed under all circumstances:

Installation, maintenance, repair, commissioning:

• Read the entire manual carefully before installing and operating the product.

• Danger to life due to high electrical voltage. Never make changes to components, software or connection cables without first disconnecting the power. For this reason, the corresponding upstream fuses must be removed and stored so that other persons cannot reinsert them unnoticed.

• The product may only be installed, repaired or maintained by an authorised electrician. All applicable local, regional and national regulations for electrical installations must be observed.

• Serial numbers before 7002702 require an upstream RCD Type-A in order to meet national installation standards. See Material recommendation RCD Type-A.

• The installation must not take place near flammable or explosive media, in flood-prone areas (underground car park) or in areas where there is a risk of running water.

• The product must be installed at a permanent location. The connections on the Pico and the back plate are designed for a limited number of plug-in cycles.

• The product must be installed on a wall or structure with sufficient load-bearing capacity.

• The connection terminals in the back plate are live when the circuit is closed and must under no circumstances be brought into contact directly or with any objects other than the Pico electronics.

• Depending on the type of installation, permits may be required before installation, e.g. if the building connection capacity is increased.

• The charging station must be registered with the grid operator.

• The screws of the cable connections should be tightened with a torque of 3 Nm. The maximum diameter of the cable with wire end ferrule is 6.5mm.

• The product must be operated in combination with a miniature circuit breaker. The short-circuit capacity of the miniature circuit breaker must correspond to the maximum short-circuit capacity of the connection point. For selectivity, one miniature circuit breaker may be sufficient for several charging stations. Observe the country-specific notes on our wiki. The stations can handle individual short circuits of up to 3kA without any problems.

FAQ

Why does the Pico always reserve 6A in the load group even though the car is no longer charging?

The IEC 61851 standard stipulates that every car must always have at least 6 A available. The standard provides for this so that a parking heater can be supplied from the grid, or so that the battery is not discharged if someone is away for several weeks.

Does Pico require an upstream RCD Type-A per charging station?

Pico charging stations with serial numbers before 7002701 require an upstream Type-A RCD 40A 30mA to meet national standards. The function is present in these devices but is not compliant. From serial number 7002702 or BY2024, the Pico no longer requires an upstream RCD; it is now integrated and compliant according to 60947-2.

Which material is suitable for this is described under Material recommendation RCD Type-A.

Does the Pico charging station support ISO15118 for Plug & Charge and V2G / V2H?

The Pico charging stations have all the technical equipment to support the ISO15118 and ISO15118-20 standard in the long term. Enabling the Pico to support the functions depends exclusively on software and does not require any hardware change or modification.

Bidirectional charging V2H and V2G with the Pico: Enabling the Pico charging station for bidirectional charging under ISO15118-20 depends exclusively on the release and availability of the functions and equipment on the part of the vehicle and the vehicle manufacturer. The charging hardware of the Pico charging station does not represent a limitation in this respect.

The first vehicles capable of this that can actually be purchased are expected in the coming years.

We are continuously working on developing these functions in our Pico charging station so that we are ready for that moment.

Can I reset the meter reading to zero?

No, since our meters are used for billing, it is not possible to reset them.
