ZDK is also known as Zhongde Energy. The SmartgridOne Controller supports two versions of the ZDK Booster product line. The booster is a DC-fast charger with a built-in battery. Typically the battery is used to support the grid when charging an EV at high power, but it can be used for other purposes.

:::danger Safety warning: risk of electrocution Disconnect power before performing the steps below. When the back panel is opened, it exposes a high voltage 800v DC bus. :::
Prerequisites: The system should be physically installed and connected to the power using the installation manual. The guide below only covers the installation if the communication with the network and with the SmartgridOne Controller.
Step 1: The communication between the SmartgridOne Controller and the ZDK Booster is established through Modbus TCP. Shutdown the power and open the back panel of the booster. Focus on the marked part in the picture:
Step 2: Use two ethernet cables to connect:
Step 3: Only for commissioning: Connect your computer with a LAN cable directly to the diagnostic interface of the Booster. This is the interface marked in purple in the image above. After commissioning, you do not need this interface anymore.
Step 4: Open the network settings on you computer, and manually assign IP address 192.168.1.101:
Step 5: Open the browser and go to . Proceed trough security dialogs if the browser warns about an insecure page.
The default username is default_admin and the default password is Default_Admin22! (pay attention to the capital letters).

Step 8: Check the firewall settings. You have two options here:
Completed: The system is now prepared for a connection with the SmartgridOne Controller. Proceed in the SmartgridOne Controller interface find the device in the wizard.
The Booster generation 2 has the following characteristics:
This means that the battery can only be (dis)charged with 80 kW from and to the grid. The discharge power is up to 200 kW when discharged to DC meant for EV charging. Depending on the battery control power, we switch between two modes that are provided by ZDK:
By default, the minimum state of charge is set to 10%. When it discharges to this level, it should be charged up to 20% before discharging again.
