Battery-ultracapacitor hybrid energy storage unit
Specification
1) Up to 100000 charge cycles. It shall be workable for ten years.
2) Non-explosive: Physical reaction instead of chemical reaction. Much safer than chemistry-based batteries.
3) Energy density is 75-220wh/kg. Lots of power in a small unit.
4) 80% charge in 5-15 minutes! Quick.
5) -40 to 70℃ range of operating temperature. Suitable for extreme conditions.
6) Low self-discharge. SOC ＞80% storing 180 days after full charge
