Flow Batteries have a significant place in Energy Storage

They have these properties:

• Scalable to 1GWh
• Long lifespan
• 100% Depth Of Discharge
• Long Discharge Time
• 100% Recyclable

However, there is a voltage constraint:

• Flow batteries natively operate at 48-70V DC
• It is difficult or impossible to place flow batteries in series at higher voltage.
• Solar MPPT and high voltage DC busses with wind power operate at 750V to 1250V DC.
• During maintenance some flow batteries require the low side to drop to 0.0 V DC.

Safiery have a modular DC DC solution:

• One DC DC per flow battery cell giving ultimate control per cell.
• Distributed control for maximum system reliability.
• Scalable up to 1 GWh of storage, with C5 Charge/Discharge.
• Isolated DC DC with 48V nominal on Low Side.
• Up to 1,250V DC on High Side.
• Bi-directional.
• LS Voltage can drop to 0.0 V on Low Side during maintenance mode.

Selectable options:

• A standard max. efficiency of 97.5%
• An upgraded model with a max efficiency of a staggering 98.5%
• Aircooled to 3.5kW, water cooled above that
• Autonomous Control
• Supervisory Control with CANbus up to 64,000 units
• AI used on PID control
• AI used on optimizing efficiency with 6D equations:

• Efficiency vs LS V,
• Efficiency vs HS V,
• Efficiency vs Temperature,
• Efficiency vs MPPT eficiency,
• Efficiency vs DOD,
• Efficiency vs Time to Maintenance.
