WIMA PowerBlock modules stores energy and releases it within short time in e.g.

• Motor start in construction,agricultural and earth moving machines, trucks,busses,vessels,generators
• Railway technology e.g locomotives, electric tramway etc.
• Hybrid and heavy transportation in e.g. construction, agricultural and forestry machines,city busses,fork­ lifts,cranes etc.
• Automated guided vehicles (AGV) in production facilities,in-plant logistic systems etc.
• Uninterruptible power supply (UPS) in hospitals, telecommunication systems,oil and gas extraction etc.
• Wind power systems e.g. in pitch control.

• Fast supply of several 100 – 1000 A in direct current operation
• Operating temperature range from -40° C to +65° C
• Maintenance-free operation with up to 1 mill on charge/discharge cycles
• Life expectancy >10 years
• Low weight against batteries or secondary batteries
• Environmentally friendly materials
• No risk of damage do to complete discharge of the component
• Very fast recharge of the PowerBiock.

The use of PowerBiocks as energy storage increases efficiency and life time of the applications,saves weight and cost for maintenance,and is environmentally friendly.
