OCPP-based system for charging electric cars.

The Woltti online service is very well suited for public charging and offers the best concept on the market for pricing, load balancing and high-quality user experience and back-end system management.

In our public charging locations, we always use the highest quality charging devices so that we can offer a reliable charging solution. Regarding the main products, we operate directly as a partner of the factory (AC: Garo, Alfen, Keba, DC:Walbox), which enables the best support, a longer than normal warranty and, for example, On-Site maintenance.

In the system, we have invested in operational reliability. All the products we use are remote controllable and most of the possible troubleshooting can be done remotely. We use high-quality components, such as Cisco remote control switches, Teltonika telecommunication products, ABB and Hager electrical components. The mobile connection to the chargers is secured and we can flexibly use the networks of different operators (Elisa, Dna, Telia).

The system can be customized according to the customer's needs or integrated with any other system using the interface. Our solution is a modern open OCPP solution, to which it is possible to connect an unlimited amount of electricity measurement (HAN/ traditional) as well as related load management and optimization. We have also used spot prices for a long time. The solution makes it possible to optimize the use of wind and solar energy as well as V2G charging.

Thanks to our own software development, we can offer a flexible system for public charging that integrates with the municipality's other systems, as well as a rental model for e.g. parking payment or various financial management systems.
