Energy Storage
Smart Battery Storage for Solar-Powered Bus Depots
Project
The bus company installed a 235 kWp photovoltaic system at its site, supplying the office building and bus depot with green solar power. Additionally, electric buses were introduced to electrify inner-city transport in Kempten, reducing greenhouse gas emissions in the transport sector. An appropriate charging infrastructure is required to ensure reliable and CO₂-neutral passenger service.With the help of the Pramac Battery Storage Container BSC 528 / 2133, the company’s self-consumption of solar energy is optimized. The 450 battery modules housed in 40-ft containers, with a total usable capacity of 1,920 kWh, ensure that as much on-site generated solar power as possible can be used. The modules are organized in 18 racks, each equipped with its own battery management system to ensure safe operation and long battery life. Air conditioning systems within the containers maintain the battery modules at their optimal operating temperature range at all times.The battery storage system is charged and discharged by the Pramac Smart Energy Controller (PSEC), an in-house-developed energy management system that acts as the brain of Pramac battery storage systems, monitoring and regulating power and energy flows within the Berchtold company’s existing energy system.
