The vital part to the successful operation of a wind turbine pitch system is the system’s backup power. As a wind farm operator, you want to be assured that your backup power source is going to pitch your blades successfully when necessary. There’s no room for failure. That’s why a reliable power source, like RELiON’s wind turbine lithium battery, is crucial to rotate the blades during an emergency shut-down situation.

Performance Characteristics
Reliable Power for Your Wind Turbine Pitch System
The RB10-PC deep cycle lithium battery is specially designed for wind turbine pitch systems. It’s perfect for use as a standby emergency power source with extremely high peak current requirements. In comparison to AGM batteries, lithium iron phosphate batteries do not decay under the constant centrifugal forces, yielding an extremely long life, thereby offering the lowest lifetime costs per kWh cycle. Up to six RB10-PC batteries (72V system) can be used in series to power the pitch of windmill blades.
Advantages of the RB10-PC Lithium Battery:
Extremely long life (up to 10x the life of a lead-acid battery)
Non-interrupt discharge (unique discharge terminals)
High discharge currents
High charge currents
High efficiency between charging and discharging
