The company offers the highest power and energy density ultracapacitors and hybrid capacitors ranging in size from 100 Farads
to 3,000 Farads
Maxwell offers ultracapacitor cells ranging in capacitance from one to 3400 farads
and multi-cell modules ranging from 16 to 160 volts, which have proven to deliver high power, whether used alone or paired with batteries, in a variety of applications from automotive or industrial to consumer electronics, transportation and beyond.
According to ACI, capacitances of more than 104 farads
per gram and energy densities of more than 325 kilojoule per kilogram have been demonstrated with carbon aerogel ultracapacitors, as have power densities of up to 20 kilowatts per kilogram.
This TesCom report also provides data on EEStor's layers increasing in energy storage as the frequency is lowered to dc (79 Nano Farads
at 100 Hz to 19.
A third contract manufacturer assembles Maxwell's HC family of small cell products, which range from one to 150 farads
, and are used mainly in industrial electronics applications.
to as high as 90 Farads
in a package that is only 2.
Primary applications for Maxwell's K2 series products, which range from 650 to 3,000 farads
, include automotive subsystems, hybrid and electric vehicle drive trains, renewable energy systems, back-up power, grid stabilization, electric rail system power and many other transportation and industrial applications that require burst power and heavy cycling that cannot be efficiently provided by a battery or power supply alone.
Primary applications for Maxwell's large cell products, which range from 650 to 3,000 farads
, include hybrid-electric transit buses, electric rail vehicles, cranes, lift trucks and other industrial systems.
Core of the technology is a double-layer capacitor with a capacity of up to 3,000 farads
per cell enough to handle several restarts in rapid succession, explains Dr.
