FAQ – RZB Energy

RZB Energy is a brand of RZB Rudolf Zimmermann, Bamberg GmbH, which stands for innovations in the field of light and electromobility. The future of mobility is changing, which we want to actively shape through RZB energy. In the first quarter of 2022, the number of electric vehicles in the DACH region was around 830,000, with a simultaneous stock of only around 41,000 charging stations. This is a very poor result, especially if we assume that the number of electrically powered vehicles will grow rapidly in the next 5 to 10 years.

With the combination of high-quality outdoor lighting and intelligent charging infrastructure, RZB ENERGY offers attractive solutions: Make e-Mobility easy.

Quality made in Germany - the products of the RZB Energy brand are manufactured at the company headquarters in Bamberg. When selecting the individual, technologically sophisticated components, we also place the highest demands on our cooperation partners and suppliers. Our partners include the market leaders PHOENIX CONTACT and Monta Platform.

Yes, this possibility exists. In the case of a retrofit, only the bollard tube and the EV Charger KIT need to be replaced. The base plate and the luminaire head can continue to be used.

This is interesting, for example, if only limited power is available at a location and therefore only a small number of charging columns can be installed. If the infrastructure is improved and the available power for the location is thus increased at a later date, additional charging columns can be put into operation with relatively little effort by retrofitting the existing luminaires.

Compliance with standards, observance of guidelines and testing of products under real conditions, both in-house and by external institutes, are very important to RZB in terms of quality awareness. The influence of the leverage on the loading solutions was investigated with a tensile weight of 120kg. The plug was attached to the tube at a height of 1.2m. Only slight deformations of the fastening screws occurred. However, the tensile weight used is significantly higher than the normal tensile force of a human arm. The fastening of the RZB Energy charging solutions is basically possible with a buried piece or foundation.

The basic software, which is available on the controller by default, is provided by Phoenix Contact. This controller is then addressed via the mini-USB interface or, if it is already in the network, directly via the IP address. As a backend, the RZB Energy products can be provided at the factory with programmed Monta software. The controllers can also be configured via this system. Updates are then applied "over the air".

The load management is set up, for example, via a MID meter and a Charx 3150 controller. The controller is connected upstream of the system, measures the available power and distributes it evenly to the controllers responsible for charging. The upstream controller can of course also reduce the power for individual charge controllers, depending on the setting.

An example: 4 cars are connected to a charging station, the upstream controller ensures that the power is distributed evenly to all 4 charging points. One of the cars has now finished charging and is removed from the system. Now the controller ensures that the power that was previously still being consumed by the charging point of the fourth car is delivered as additional power to the three vehicles still charging.

In principle, each project always has got it`s individual conditions and prerequisites. However, some factors to be determined can be described as generally valid, these include:

-the total power available to the site,

- the difference between the available power and the power already consumed by the site (building services, machinery, etc.),

- planned access to the charging station (private, semi-public, public),

-desired type of billing.
