Valve-regulated sealed batteries (VRLA)

Valve-regulated sealed batteries for railway rolling stock, as a key onboard energy storage device, are mainly used for starting diesel locomotives, emergency backup power supply and auxiliary system power supply to ensure the safety and reliability of vehicle operation.

Product advantages

  1. Sealing and maintenance-free design: It adopts valve-controlled sealing technology to maintain air-tight and liquid-tight conditions during normal use. There is no need to add acid or water regularly, reducing maintenance workload and environmental pollution risks.
  2. High reliability and safety: It has the functions of explosion-proof, acid mist proof, liquid leakage proof, etc. The safety valve can automatically open or close when the internal air pressure is abnormal, ensuring the safe operation of the battery under various working conditions.
  3. Large current discharge capability: It can withstand large starting current and emergency discharge current, meeting the high power requirements of railway rolling stock under starting, /braking and other working conditions.
  4. Good low-temperature performance: It can still maintain a certain discharge capacity in low-temperature environments (such as -40°C), adapting to the operating needs of railway vehicles under different climate conditions.
  5. Long cycle life: By optimizing battery materials and structural design, the cycle life of the battery is extended and replacement costs are reduced.
