First master-slave EV charger presented by Circontrol

By / 4 weeks ago / Tech / No Comments

Circontrol has launched a new master-slave charge point for electric vehicles (EVs) that the Barcelona based company says can reduce operational and maintenance costs.

Circontrol master-slave

Circontrol presented the new system at EVS30 in Stuttgart.

The solution offers multiple charging consisting several slave points controlled by a single master unit. The new system also allows a DC Quick Charger (Raption Series) or an AC charging post (Post eVolve Range) to act as master and a ground-mount (eVolve Post) or wall-mount (WallBox eVolve) AC charger to act as a slave, the company added.

The advantage to company’s, Circontrol said, is that the system only uses one master unit (that is also a charge point) containing all the necessary hardware to control a grid of slave charge points. Therefore, the slave units can be made cheaper and are simpler to install, so capital expenditure (CAPEX) is lower. In addition, operating costs (OPEX) are reduced as, for example, a single 3G signal can be used on the master unit for the benefit of all the charge points, rather than requiring a 3G signal per charger as per traditional systems.

In common systems, control of several charge points (for example providing consumers IDs, power consumption monitoring, service support, configuration and more) would require costly smart chargers with each being individually connected to a back end control – typically operated by a third party.
