Title:
ENERGY STORAGE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/053403
Kind Code:
A3
Abstract:
An integrated energy storage system can include a first,second, and third energy storage units and a controller. The first energy storage units can have a gravimetric energy density of greater than 180 Wh/kg and volumetric energy density greater than 450 Wh/L in an environmental temperature above 0ºC, the second energy storage units can have a gravimetric power density of greater than 450 W/kg and volumetric power density greater than 1080 W/L in an environmental temperature above 0ºC, and the third energy storage units can be configured to operate in an environmental temperature as low as -100ºC The controller can be programmed to receive inputs from voltage sensors, current sensors, and temperature sensors, and to allocate the current or power among the first, second, or third energy storage units depending on a power consumption from an application load and an environmental temperature.
