Electrostatic Storage
WEST is redefining storage technology with its
hybrid-supercapacitor energy storage systems
Supercapacitors offer vast advantages over electrochemical storage in terms of power delivery, longevity, scalability, safety, reliability, efficiency, operational temperature and much more. Design with confidence – there is no need to compensate for degradation, efficiency, BMS limitations, or other factors associated with chemical batteries.
Scalable energy storage building blocks with an expected lifespan of several decades
Fully autonomous – no periodic maintenance required for the lifetime of the product
All components are replaceable – easy repair or update in the field with a minimum of tools and parts
Robust tolerance to hot and cold environments – no need for parasitic loads to heat and cool
EXTREMELY LONG LIFE
WEST modules are scalable energy storage building blocks with an expected lifespan of > 30 years. No regular maintenance is required, and the modules can be serviced in the field.
100% USABLE CAPACITY
Many battery manufacturers tell customers they can use 100% of the storage. This is false and is compensated for by 1) placing more than nameplate capacity into the box and 2) building significant degradation allowance into the warranty.
LEADER IN CYCLES PER DAY
WEST modules are capable of more than one charging and discharging cycle per day. No chemical battery can compete with this performance.
FAST CHARGING / DISCHARGING
WEST modules are capable of 30-minute charging and discharging. No chemical battery can compete with this performance.
NO CAPACITY DEGRADATION
Proven in the field in extreme temperatures for 9 years without degradation. Since the technology provides for electrostatic storage (energy stored as energy), instead of a heat-producing electrochemical reaction (energy stored in a chemical), there is no stress on the materials over time.
NO HEAT GENERATION OR THERMAL RUNAWAY
Chemical batteries produce heating during operation which, at a certain point, can become exothermic, meaning they will burn at a temperature that is self-sustaining and extremely difficult to extinguish. Because WEST modules operate without creating heat, this risk does not exist.
WIDE OPERATING TEMPERATURE
WEST modules can operate in a wide range of temperatures, from -30F to +140F, without experiencing damage. Lithium-ion batteries will lose capacity in cold temperatures and experience permanent degradation at temperatures over +113F.
MAINTENANCE FREE
WEST modules need no periodic maintenance as they monitor and protect themselves throughout their lifetimes.
ADEQUATE ENERGY DENSITY
While lithium-ion can boast higher energy density, in stationary applications energy density is not a critical factor. Much more important are the nine other factors already discussed.
CARBON-BASED MATERIAL
WEST energy storage is largely carbon-based, allowing for efficient, safe, and long-term electrostatic storage of energy.
COMPLETELY MODULAR CONSTRUCTION
In the rare event of a component failure, WEST is the only “battery” that allows for easy service or replacement in the field of every module part, eliminating the need for costly offsite repairs or replacements.
ULTRA-HIGH
EFFICIENCY OF 99.1%
WEST modules are highly efficient at 99.1%. Imagine, for instance, if every single charging cycle lost 10% (in heat). Over time these losses become prohibitively expensive.
