Product introduction:

The service life of the pitch backup power supply (lead-acid battery) of Sinovel SL1500 fan is about 2 years due to unreasonable design and other factors, resulting in frequent replacement and affecting the power generation. By replacing the lead acid battery with the lithium ion battery, the battery life is extended from about 2 years to 5 to 8 years, which can reduce the downtime caused by frequent damage of the lead acid battery, reduce the equipment maintenance costs and the loss of electricity from discarded wind, save the operation and maintenance costs, and enhance the safety of the unit. The use of lithium ion battery in the wind farm instead of lead-acid battery can improve battery life several times, reduce unit failure rate and save operation and maintenance costs.

Technical project introduction:

The original lead-acid battery is changed into lithium battery. The specification of the lithium battery is 374.8V 5.3Ah, which consists of a battery management module and four 93.6V 5.3Ah lithium battery modules in series
