1. Short Description of Technology
clean energy and Faktor/AWE present the first TÜV certified megawatt storage system called . Themegamax
electrical energy storage system based on battery energy storage technology includes state of art superior
batteries: lithium-iron-phosphate batteries. An especially developed two-way, high-capacity inverter and
transformator (2 x 250 kW, 3-phase, 0.4 kV) is responsible for the loading of the battery blocks by the grid as
well as for feeding the grid with the storage system’s energy. The storage units can be operated and managed
remotely via the AWE BSVPP monitoring and process control system (BSVPP: Battery Strengthen Virtual Power
Plant). Operating and managing is a geographically independent procedure. The equipment is going to be placed
in a 40’ feet high sea container. The container includes all the major equipment, the control system and the
cooling technology, which is capable to maintain the required temperature. The cooling technology is also
operated by the control unit. Because of its standard size and design, the plant is mobile and can easily be
moved. But it is also applicable for stationary use inside as well as outside of buildings or halls.

3. Main Storage Applications
I. The Lithium Energy Storage is very suitable for ancillary service purpose (control energy) because of
its short reaction time.
II. It serves for interference filtering on medium and high voltage system level in order to prevent
disturbances and damages of sensitive electronic equipments.
III. The Storage System maintains uninterrupted power in case of electrical outage: UPS function!
Because of the very short switching time (only milliseconds!) the availability of the changeover
voltage downstream and the availability of the changeover function are absolutely ensured.
IV. The Storage System is able to feed in a defined idle power into the medium-voltage grid not only in
normal operation, but also during a short breakdown of the voltage in the high or highest-voltage
grid.

V. The MW-Storage can be used as a mobile off-grid power station providing energy where normally is
none: in emergency cases, for out-door events, geological research areas, …)
VI. Storages in combination with PV-parks, provide power during night time in order to keepmegamax
going the system connection with the surrounding distribution grid.
4. Battery Technologies in comparison:
Li-iron-phosphate batteries – a leading edge technology
Our Storage System is based on the Li-iron-phosphate battery technology. The overview shows why:
Technology Advantages Disadvantages
Modern lead-acid
battery
1. Well known technology
2. Cheapest battery (USD/Ah)
1. Low energy density, relatively high
space requirements
2. <1000 cycle lifetime
3. High environmental impact
NaS battery 1. Higher energy density compared to
VBR and Lead-Acid
2. High lifetime(even 6000 cycle)
3. Low environmental impact
through lifecycle
1. Flammable technology 00- 0 C –
fire accident in Japan in
September of 2011)
2. Through corrosion problems the
self discharge rate increases
constantly in time
Vanadium Redox
battery VRB
1. Higher energy density compared to
Lead-Acid.
2. High lifetime (10000 cycle)
3. Closed system
1. Lower energy density compared to
NaS and Li-ion technologie, higher
space requirements
2. Limited experience in industrial
scale
3. High environmental impact
through acidic technology
4. High fixed cost
5. Not maintenance free
Lithium Polymer
battery
Li-Kobalt, Li-
Mangan …
1. Higher energy density and
therefore lower weight and less
volume compared to LiFePO4
2. Minimal maintainance
1. Explosive and oxygen-reactive
cells! (Dreamliner accidents
2013!)
2. Only 1000 cycles lifetime
3. Limited industrial scale experience
4. Need nearly double the amount of
Lithium in comparison to LiFePO4
batteries
Lithium Iron
Phosphate battery
(LiFePO4)
1. Self secure; non explosive!
2. Higher energy density compared to
Lead-Acid and VRB
3. relatively small place requirements
4. Very long lifetime: >5000 cycles
and more
5. Nearly maintenance-free
6. Low environmental impact
1. Limited industrial scale experience
2. A bit more volume and weight
than LiPolymer batteries
