As a global player in lithium-ion battery systems, the BMZ Group develops large-scale batteries for vehicles like buses, forklifts, cranes, sweepers, commercial vehicles in harbours and airports, E-taxis, industrial trucks, and E-boats.
The advantages of BMZ lithium-ion battery technologies are their quick-charging capabilities and long service life of up to 20 years. They are a sensible and economical alternative to maintenance-intensive lead-acid batteries. BMZ produces modular battery systems with 24 to 48 volts that can be connected in parallel and cascaded up to 800 volts.
Module production with laser welding robots
These customer-specific BMZ lithium-ion batteries use battery cells from the automotive industry. The new technology fulfils the highest safety and stability requirements. The high-quality installed automotive cells withstand 4,000 charging cycles. Module production at BMZ is handled fully automatically by laser welding robots.
BMZ supports its customers in building the car of the future, helping them achieve new dimensions of mobility. Electric vehicles are quiet, reliable, and low-emission. They use the best infrastructure for recharging.
Batteryuniversity Tests Large-Scale Batteries
BMZ is working closely with DAKKS accredited Batteryuniversity GmbH, an independent subsidiary of the BMZ Group, to meet all of the safety requirements and obtain all permits required for global shipment and sale. For the customer, the advantage is that we can handle all required nationally-specific permits quickly and reliably from a single source.
New test benches at Batteryuniversity GmbH are able to test large batteries for electric cars or forklifts. The 120 kilonewton BU shaker can handle loads of up to 800 kilogrammes, and can test noise profiles, sine sweeps, superimposed sine waves, and shock impulses.
