4. Product description

4.1 Purpose, operation and function

The Smart Charge Controller is an electronic device that is used in combination with an EV charging station. The device measures the mains current and regulates the charging current of the EV charging station based on the Dynamic Load Balancing function of the charging station and a chosen charging mode. Any EV charging station that supports Dynamic Load Balancing based on a Modbus RTU or Modbus TCP/IP current meter can be controlled if the correct configuration is installed on the Smart Charge Controller. The Smart Charge Controller can be used for both single-phase and multiphase installations. A maximum of 3 current transformers can be connected to the Smart Charge Controller to measure the mains current. Optionally, the P1 output of a connected smart meter can be used to measure the grid current. Wi-Fi is available to commission the device and to enable firmware updates when connected to the internet via the home router. The device is powered from the mains. The user selects the charging mode via the user interface, which consists of an OLED display and 3 buttons. The following charging modes are available: PV only, PV + 6 A and Capacity (4-22kW, in 1 kW steps) Selecting the charging mode via a smartphone app is a future feature. The purpose of the Smart Charge Controller is to externally control the actual charging current used by EV charging. Based on: · The Dynamic Load Balancing function of the EV charging station · The selected operating mode of the Smart Charge Controller · GRID parameter settings · The processed/recalculated current by the Smart Charge Controller And this is for the purpose of energy management in the context of: · Optimisation of own consumption · Capacity tariff

4.3 Conditions for the proper functioning of the energy management function

The proper functioning of the energy management function of the Smart Charge Controller depends on the Dynamic Load Balancing functionality of the EV charging station.

It is assumed that this Dynamic Load Balancing functionality works as follows: · When dynamic load balancing is enabled, the charging station works as a modbus master and the connected Smart
Charge Controller acts as a modbus slave. · The purpose of dynamic load balancing is to charge the car as quickly as possible, so the charge point asks the meter how much
power is currently being consumed by the mains connection so that the remaining power from the mains connection can be used
to charge the car. · The charge point thus charges the car with a calculated maximum current of : “Maximum current of the mains connection point – the
current mains consumption of the household.”

8. Use / operation

8.1 Charging mode
In charging mode, the desired charging mode or capacity of the EV charge point can be selected from 4 kW to 22 kW. However, the maximum power displayed in the menu depends on the max. capacity of the EV charge point, this is a device setting (see operating instructions EV charge point). There are charging modes: · ECO+ (PV only) = charging only with power that is fed into the grid · ECO (PV + 6 A) = charging with fed-in power + 6 A · Capacity = charging with set maximum capacity between 4-22kW, adjustable in steps of 1kW.
() Maximum adjustable capacity depends on the grid setting “Max charge current” at commissioning
