Customer Specific Requirements
Each application has different requirements. Charging profiles, load profiles differ but also the operational conditions like temperature, mechanical stress as well as available space and weight restrictions. Does the battery operate in space (under vacuum conditions), in wet environments, etc. Therefore we suggest customers start with filling in the Requirements Sheet.
Based on this input we select the best cell type, configure one or more suitable battery configurations, propose an adequate packaging (aluminium, steel, stainless less, ….), and add the required safety devices like fused switches, touch-safe connectors and cables, voltage indicators, etc.
Below some examples of previous projects.
Most of our powercapacitors batteries are customer-specific.
Powercapacitor batteries have many benefits for industrial vehicles like forklifts and AGVs. They charge very fast, operate in cold and hot environments and have a long lifetime with close to zero maintenance. Hence the ROI is much higher as the vehicles can operate 24/24 and might even outlive the vehicle.
Powercapacitors find often use in heavy high-performance batteries in applications such as
- Hybrid drives, such as a 300 kW system using 250 kW fuel cells with a 30 kWh powercapacitor battery.
- Hybrid generators, such a 200 kW fuel cell with a 25 kWh powercapacitor battery.
- Battery-electric trains, using 1 to more MWh powercapacitor batteries.
- Battery-electric or hybrid ships and ferries, using 1 to 10 MWh powercapacitor batteries
- High energy storage and grid stabilisation, from a few kWh to several 10’s of MWh.
These large systems often use the 18500 cells when the C-rate is < 3C or 18650 cells when the C-rate can reach > 10C. This allows fast charging and discharging. Hence a 20 kWh pack be drained at up to 250 kW till depleted. Benefits are no BMS, no active cooling (except some air ventilation), safety (no fire risk) and a lifetime of upto 30 years (depending on the load profile) with close to zero maintenance. Large batteries are composed by putting severla packs in parallel, e.g. 60 packs of 30 kWh provide 1.8 MWh. Typical voltage are between 450 and 800 VDC.
