TÜV-certified Batteries for use in Wind Turbines

In wind turbines, the TÜV-certified NP7-12 battery from GS YUASA buffers the power supply of the pitch systems.

GS YUASA has developed the powerful and TÜV-certified NP batteries buffering pitch motors in wind turbines.

In order to keep the power output of a wind turbine as constant as possible at different wind speeds, the blade angle adjustment has become established. This stepless adjustment of the rotor blades is usually working electrically using pitch motors. In strong winds, a control system turns the rotor blades around the longitudinal axis out of the wind. In storms of 25m/s or more, the wind turbine is shut down to prevent damage to the generator. For this purpose, the rotor blades are turned by almost 90° into the feathering position. Batteries buffer this power supply so that the pitch system can continue operating reliably even in the event of a power failure. To be on the safe side, each motor has its own buffer battery, which is subjected to very short autonomies with very high discharge currents that are a multiple of the rated capacity.
 
For this demanding application with the battery being exposed to shocks and vibrations, GS YUASA has developed the 12V NP battery series. The NP7-12 and NPH5-12 types are even TÜV-certified according to the standards for determining resistance, DIN EN 60068-2-6:2008, DIN EN 61373:2011 and DIN EN 60068-2-27:1995. The 20-hour rated capacity of the batteries is 5Ah (NPH5-12) and 7Ah (NP7-12). In addition, the batteries are highly reliable and fast recovering after deep discharge. Due to AGM technology, operation in almost any position (except overhead) is possible without loss of power, even in moving parts. Special lead-calcium grids ensure a long service life of 3 to 6 years according to EUROBAT, making a replacement outside the usual service intervals not necessary. This is particularly important in the offshore sector, where service costs are very high. Water refilling is also not necessary over the entire service life.

GS YUASA’s NP battery series are TÜV-certified and used in pitch systems of wind turbines, among other applications.
