OCPP-compatible overall solution for public charging. Plug-and-play devices.

Various solutions are available for public locations depending on the destination, capacity and the need for charging speed. The main advantage of a fast charging station (DC 30-300kW) is significantly higher charging power and thus faster charging. Fast charging brings comfort on long journeys, when the battery can be charged quickly during a short stop. Fast charging stations are well suited for, for example, public parking lots, gas stations, taxi operators, car dealerships or e.g. transport companies.

Basic charging (AC 11-22kW) is still the best solution for most public charging. The construction of charging stations is possible at considerably cheaper costs than fast charging. It is also possible to combine both charging methods with the target, then you can use the advantages of both charging methods.

The Woltti online service is very well suited for public charging and offers the best concept on the market for pricing, load management 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.

In public charging, the user is offered a free App (Apple/Android) that can handle practical matters related to charging, e.g. identification, monitoring of downloads and payments by credit card.
