Battery storage

With peak shaving, the battery covers consumption peaks from its stored energy so that the power drawn from the grid stays below a set limit. PRAMAC’s EV-Boost Box supplies additional power for the charging stations of the company fleet during demand peaks and stores electricity from photovoltaics. The platform Novatec developed for a storage manufacturer also lists peak shaving as a central use case, alongside self-consumption optimisation.

Besides its state of charge, a connected battery storage system mainly provides data on ageing and stress. As live data according to DIN DKE SPEC 99100, the Battery.live passport lists capacity and degradation, battery resistance, charging cycles, deep discharge and overcharge events, temperature and the state of charge, among other values. On platforms such as the one built by Novatec, operators use this data to control individual units and entire groups, maximising service life and reducing operating costs.

The digital battery passport brings together the relevant data on a battery’s origin, composition and recyclability, as required by EU Battery Regulation 2023/1542. HK.DIGITAL’s Battery.live adds live operating data to static information such as manufacturer, carbon footprint, battery chemistry and spare parts. Users access it via QR code or NFC on a smartphone without installing any software first. The basic application is available free of charge under the Apache 2.0 open-source licence.

Commercial energy storage is more likely to pay off when it performs several tasks: shaving load peaks, increasing self-consumption and offering capacity on the electricity market. The platform Novatec built on Microsoft Azure for a manufacturer of redox flow batteries is designed for capacity trading and marketing via direct marketers. The manufacturer uses it to manage batteries at different sites centrally and to market their capacity as energy as a service.
