Pico EV Charger

RDC-DD 6mA according to IEC 62955 (residual direct current detecting device)

Pico is the Swiss high-tech charging station. It connects directly to the cloud via Wi-Fi or mobile communications. The integrated smart meter exports high-precision measurement data that is signed during transactions and can be validated at any time free of charge. The station can be integrated into a backend (eCarUp), energy management systems and other third-party systems. Furthermore, Pico can be used for both static and dynamic load management (including phase balancing).

This article covers the first Pico generation (article number 202170exA). All information on the latest Pico version can be found here: Pico EV Charger.

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.

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

Cable routing

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

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

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

Details on mounting the stand can be found in the installation instructions under Downloads.

Load Shedding (External Inputs)

Pico load shedding

Load shedding can also be implemented using just 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.

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

Alternatively, load shedding can also be carried out via the if/then actions and Pico control.

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 from high electrical voltage. Never make changes to components, software or connection cables unless they are de-energized. For this reason, the corresponding upstream fuses must be removed and stored in such a way that other persons cannot reinsert them unnoticed.
The product may only be installed, repaired or maintained by an authorized electrician. All applicable local, regional and national regulations for electrical installations must be observed.
Installation must not take place near flammable or explosive media, in flood-prone areas (underground car parks) 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 cycles.

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 other objects, with anything other than the Pico electronics.
Depending on the type of installation, permits may be required before installation, e.g. when increasing the building connection capacity.
The charging station must be registered with the grid operator.
