Generally speaking, you can connect a Heidelberg Wallbox to a solar power system and charge your car with the surplus power produced. With the Heidelberg Wallbox Home Eco, you can switch the power supply of the solar power system on and off via the system’s inverter. The solar power system is connected via the isolated contact on the Wallbox PCB. The Heidelberg Wallbox Energy Control is the better choice for this application. With the Wallbox Energy Control, the charging current can be controlled dynamically via the so-called Modbus.

Product information: Wallbox Energy Control

No! You must not make any changes to the Wallbox after delivery; the functional and safety test performed in the factory is only valid for the Wallbox’s condition on delivery. Changes to this condition will void the guarantee and warranty. There are no spare parts available at this time.

Once the Wallbox is disconnected from your vehicle, it switches to standby mode to save energy. In this mode, the Wallbox deactivates as many functions as possible, e.g. the lighting. Power consumption is reduced to 1-1.3 W (depending on the model). The remaining power is needed by the signal processing electronics to detect a car being connected to the unit and to wake up the Wallbox into operating mode.

The Heidelberg Wallbox Home Eco indicates its status and any errors via an LED at the side of the Wallbox. The Heidelberg Wallbox Energy Control uses the front light for this purpose. See the respective operating manual for details.

The Heidelberg Wallbox Energy Control has a communication interface (RS485) that permits external control and diagnosis based on the Modbus RTU protocol. In addition, both the Wallbox Energy Control and the Wallbox Home Eco have an isolated signal input.

In a network of several charging points, the load management function ensures that the connected load of the main charging connection is not exceeded. That is it keeps overload devices from triggering, which would limit the availability of the charging points. The load management function constantly monitors the power requirement versus the available power. If the power requirement exceeds the available power, the load management function limits the charging capacity by directing less power to the individual charging points.

Most significantly, the Heidelberg Wallbox Energy Control has a communication interface (RS485). This permits (1) dynamic load management at the charging point and (2) the use an external control unit: It is possible to interconnect several Energy Control units, which can then control themselves, creating a self-contained, static charging system that intelligently distributes the charging capacity between the connected Wallboxes. The Wallbox Energy Control can be connected to an external energy management system (HEMS). This allows for functionalities like charging with surplus power from a solar power system. Beyond these functional differences, the Heidelberg Wallbox Energy Control indicates its status and any errors not with an LED at the side like the Wallbox Home Eco, but using the front light. In addition, the Heidelberg Wallbox Energy Control comes with a stainless steel frame.

Product information: Column

Yes, both Wallboxes have the same mounting plate and can be installed on the Heidelberg column.

Charging process

The white front light flashes more slowly.

Home Eco: The LED at the side flashes green. Energy Control: The front light flashes white.

The Heidelberg Wallbox Home Eco can charge your car with up to 11 kW, depending on the car’s charging capacity and your power connection. If your car has a charging capacity of only 3.7 kW, that is no problem for the Heidelberg Wallbox Home Eco: The car determines how much power it draws; the Wallbox only ensures that the maximum connected load is not exceeded.

No, the Heidelberg Wallbox Home Eco only has one charging cable and can therefore only charge one car at a time.

Yes, the external locking device (isolated switch) can be controlled by a time switch, for instance.

The charging process stops automatically once the battery is full. If you car’s battery starts to deplete again, e.g. because of an auxiliary heating system, charging will recommence.

Yes, you can also use the Heidelberg Wallbox Home Eco or Wallbox Energy Control if you are a tenant or live in an apartment building. In this case, we recommend installing an optional external locking device (isolated switch) to protect the Wallbox from electricity theft. Also, please remember to get your landlord’s or community association’s consent before installing a Wallbox!

The Heidelberg Wallbox is designed for maximum safety. The smart charging electronics ensure that charging is not started until the charging plug has been locked correctly in the car’s socket. Also, Heidelberg Wallboxes have an integrated residual current detector that detects alternative currents (AC) of 30 mA and direct currents (DC) of 6 mA.

The Heidelberg Wallbox is a plug-and-play system. Simply connect the charging plug of the Wallbox to your car’s charging socket. If you are using an optional external locking device, you must unlock it to enable the charging process.

The charging time with the Heidelberg Wallboxes depends on your car’s charging capacity and your power connection. The Heidelberg Wallboxes can charge your car with up to 11 kW. Ask your electricity supplier or electrician about the charging capacity available at the point of installation. You can easily calculate the charging time of your car if you divide your battery capacity by the charging capacity: charging time = battery capacity / charging capacity

You do not always have to fully charge your car’s battery. A partial charge is enough. The charging process can be started and interrupted at any time, e.g. if you have little time for charging.

You can stop the charging process of the Heidelberg Wallboxes at any time by unlocking your car and removing the charging plug from the car’s socket. Another possibility of interrupting charging is using an optional external locking device (e.g. an external isolated switch connected to the Wallbox).

An interruption of the charging process poses no problem. If the charging cable is still connected to the car after the interruption, your Heidelberg Wallbox will automatically restart the charging process.

Please check the status LED on the right side of the Heidelberg Wallbox Home Eco and correct the fault as described in the operating manual.

Installation

The communication connection with the RS-485 bus is made by connecting the two wires of a shielded bus line to the appropriate terminals in the Wallbox. Bus terminating resistors are installed and can be adjusted. See the load management documentation for details.

Adjustments to the Wallbox are made using microswitches and rotary switches. Adjustments and modifications may only be made by professionals. See the installation manual for details.

The MCB must allow 8-10 times the nominal current and must not exceed a maximum nominal current of 16 A, depending on the specified capacity of the charging system.

During installation, the electrician can choose a type A RCCB for the prescribed RCCB (Residual Current operated Circuit-Breaker). The integrated RDC-M-module fulfills the protection goals of IEC 62955-1.

The AC Wallbox is an intelligent switch that merely connects the vehicle to be charged with the power supply. The Wallbox’s own power requirement is in the mW/W range; this means the Wallbox does not generate any appreciable harmonics and the cos phi is approximately 1. This fact is documented via the applied harmonized EN 61000-6-3 standard within the framework of the EU Declaration of Conformity. The harmonics that are relevant to the grid operator are generated by the charging device in the vehicle (electronic charger), but Heidelberg can offer no information on this subject.

The DC fault current shutdown of the Heidelberg Wallbox Home Eco and Energy Control fulfills the protection goals of IEC 62955-1. The prescribed RCD according to EN 61851-1 and HD 60364-7-722 can therefore be an RCD type A.

Important NOTE! The DC disconnection is not a personal protection device in the sense of HD 60364-41. It can therefore not be tested in accordance with HD 60364-6 or EN 50110 -1 and -2 with the usual test devices (installation testers). In the test mode RCD type B of the test devices, the DC disconnection cannot be tested.

The DC switch-off must be triggered after a maximum of 10 seconds in the event of a DC fault current of 6 mA.

 

 

Yes, the Heidelberg Wallbox Energy Control is equipped with an RS485 bus that uses the Modbus RTU protocol. Any control system that supports this standard can control up to 16 Heidelberg Energy Control Wallboxes per bus. If you are using a Loxone server, you will need a Loxone Modbus extension.
