Wattstor partners with HEP, the Croatian national energy supplier to enable an EV charging site in Kalovac County to reduce demand peaks.
The EV charging hub features 4x50kW and 1x175kW Electric Vehicle chargers which are connected into one transformer station. Planned further expansion of EV charging on site would require an expensive strengthening of the grid connection.
Wattstor have supplied and commissioned a state-of-the-art Energy Management System (EMS) and a containerised Battery Storage System which supplements grid power and provides peak-shaving capability when demand exceeds pre-set values of allowed consumption from the grid.
As well as offering peak-shaving functionality Wattstor’s proprietary EMS can also optimise charging available according to customer requirements such as:
• First in, first out
• Priority to chosen charges
• Time based optimisation to take advantage of dynamic time of use energy tariffs
The use of Wattstor’s platform also means that the end user can integrate new generation, storage, operational load and further electric vehicle charging without needing to upgrade their EMS in the future.
Excitingly, this initial project is operating as a pilot study and once proven to be successful will be rolled out at other service stations across the region.
The project was funded under the NEXT-E consortium, a unique cooperation of four leading companies from the electricity and oil & gas sectors joining forces with car manufacturers to create a interoperable and non-discriminatory EV charging network, as a viable alternative to combustion engine vehicles. The consortium consists of the following companies: E.ON Group, MOL Group, Hrvatska elektroprivreda in Croatia, PETROL (in Slovenia and Croatia), as well as Nissan and BMW.
A number of Croatian research institutes have also joined the project and will be collecting data from the site to learn more about EV charging behaviour and help inform the country’s future EV charging strategies.
