New boost for electricity storage systems

Besides increasing the range of their vehicles, electric car manufacturers are giving priority to reducing charging times. However, charging times depend not only on the configuration of the electric vehicle, but on the output of the charging station as well. While domestic wall boxes offer charging power of between 3 and 22 kilowatts depending on the model, high-speed charging stations have outputs of around 50 kilowatts.

Since the launch of Tesla’s 120-kilowatt Supercharger, charging stations have been on the agenda for automobile manufacturers too. In fact, Porsche is on the verge of raising the bar considerably higher in this area – with talk of a staggering 320 kilowatts of charging power!

ADS-TEC, a company based in the German town of Nürtingen, and the Porsche Engineering Group recently unveiled their jointly developed HPC Booster. HPC stands for “high power charger” and refers to both the battery storage system – which is less than 2 cubic meters in size and includes a battery, inverter, climate control, control unit, energy management system, security/firewall and communication unit – and the corresponding HPC Dispenser high-speed charging stations for DC charging power of 160 kilowatts (2 charging stations) or 320 kilowatts (1 charging station). In order to provide it with its own power supply, the booster can be directly connected to the distribution grid at the 400 V level.

The buffer storage unit provides local reinforcement for the existing power grid and, in the right conditions, should dispense with the need for considerably more expensive development work on the grid to enable the connection of high-speed charging stations. This has naturally made the system particularly interesting for regional utility companies, who have identified the installation and operation of these turbo charging stations in public spaces as a new business model to pursue. The idea of stopping by the supermarket and returning to your car to find it fully charged is undoubtedly highly appealing.

For the manufacturers of battery storage systems, this opens up a new application for their products – giving the electricity storage sector a further boost.
