The wishes of customers to be able to charge several e-cars at the same time were heard by the manufacturers. For example at Heidelberger Druckmaschinen AG. With its Heidelberg Combox Lite, it launched a system on the market in 2021 that was presented at the virtual Hannover Messe 2021 and that controls the charging infrastructure in an intelligent and transparent manner. And this for up to 16 e-cars.

These up to 16 cars can be charged at the same time via 16 Heidelberg Energy Control Wallboxes, all of which have been networked with each other by the Heidelberg Combox Lite Smart. A safe and user-friendly option for parallel and simultaneous charging of the batteries.

This system is particularly interesting for the operators of apartment buildings and hotels, who can use it to centrally regulate the parking spaces assigned to customers and tenants.

The control of the charging infrastructure is taken over by the Combox Lite in the leader function. It also has control over the connected wallboxes in a locally dynamic load management system. Up to 16 wallboxes can be integrated into the network.

However, the Heidelberg Combox Lite itself does not have any charging function.
Like the Heidelberg Combox variant, the Lite version can be installed as far away as you want from the connected wallboxes.

The standard application protocol OCPP 1.6 is used for communication between the Heidelberg Combox Lite charging management and the connected wallboxes. It also allows the connection to different backend providers with a cloud. This makes it possible to control the entire system remotely.

The networked Heidelberg Wallbox Energy Control is controlled via the network interface. This also provides the user with information on the current charge status and allows diagnoses and evaluations. Access to important current data and data from previous processes can also be called up via the backend system or web interface. A software update can also be carried out via the interface.

The Heidelberg Combox Lite is installed directly in the control cabinet or in the sub-distributor. In contrast to the Heidelberg Combox, it cannot be installed outdoors.

Products from the field of e-technology from the manufacturer Heidelberg Druckmaschinen AG have often been positively evaluated in tests. And this because of the high-quality and qualitative production. And for this product, too, the company guarantees manufacturing based on the zero-defect principle.
