Overview
The 30kW 1000V fast wallbox EV charger with DC input is a highly advanced and efficient charging solution for providing EV charging possibilities at sites with weak grid connection and already installed DC microgrid or DC-coupled installation with integrated battery energy storage.
This all-in-pack solution features integrated electrical DC input and output protections and precharge and requires no external components to connect to the DC grid.
The charger also comes equipped with Ethernet, Wi-Fi, and 4G LTE connectivity options, with in-built OCPP support, allowing for easy integration and management by any charging stations e-mobility operator.
The energy management capabilities and connection protocols are directly transferred from the best industry practices making it easy to be integrated into the modern complex DC grids with centralized control.
The high-quality 10” color display provides real-time information, making it user-friendly and easy to operate. Available for customization based on operators’ requests.
The charger provides true power output of 30 kilowatts when input voltage is over 650V and will keep charging the vehicle even with well-exhausted EV batteries being down to 300V. Being possible to output voltage up to 1000V, this charger can charge any vehicle on the market – low-voltage architectures, high-voltage architectures, and even buses and trucks.
Sequential Charging
This 30kW EV charger is equipped with 2 connectors that can charge 2 electric vehicles. It provides maximum power to one of the vehicles for some time and then maximum power to the other one. In this sense, a sequential charging is executed. Different algorithms can be applied for charging the two vehicles over a certain period – based on time and based on SoC. Custom algorithms can be designed on request.

Changing the paradigm
The regular fast EV charger converts the AC grid energy to DC power while EV batteries operate on direct current (DC). The constantly increasing demand for improved and sustained electric vehicle charging and especially fast EV charging will result in higher stress over the existing AC electrical networks, while they will tend to stay limited because of the enormous capital investments needed to be done to align them to the coming requirements.
Our mission in Ampernext is providing innovative solutions and methods for rapid EV charging that take advantage of the latest technologies and advancements in smart DC networks, microgrids, battery storage hubs and mixed AC-DC coupled grids. Such an approach brings minimal to none impact of the existing AC infrastructure, while maximizing site revenue to the site owner.
Our DC-DC EV chargers based on the Elevation DC platform eliminate the need for AC to DC conversion bringing energy savings and faster changing times. This will change the whole paradigm of how the EV charging infrastructure will be built in the future.
