  The safety and reliability of batteries have become the core concern, and the road spectrum testing conditions are stringent

  The rise of electric vehicles has propo- sed higher requirements for the safety and reliability of lithium batteries. The simulation of various actual working conditions and the road spectrum testing have put forward higher require- ments for the dynamic response and performance of the testing power supply.

  The application scenarios of lithium battery terminals tend to present large capacity, high voltage and low cost

  The capacity and voltage of lithium bat- teries have grown, and the production costs have declined; the testing equip- ment needs to gradually develop towar- ds high power, high voltage and high efficiency. Meanwhile, the rapid development of high-end lithium battery application fields, such as the increas- ing refinement of indicators such as range estimation in manufacturing of new energy vehicles, has put forward higher quality requirements for lithium batteries in terms of consistency, capa- city, lifespan and discharge rate, there- by promoting the continuous improve- ment of detection precision and stability of lithium battery detection systems.

  Overseas battery cell expansion demand

  The expansion of overseas battery cell production capacity has driven the export demand for testing equipment, accompanied by growing operation and maintenance costs and upgrading of certification standards in multiple coun- tries. 

• 

  Fast switching without voltage difference in both positive and negative directions is provided, which meets the rapid response requirements of testing equipment; the full load charge and discharge switching speed is less than 5ms, and the voltage overshoot is small; it can fully simulate various harsh working conditions for road spectrum testing, and perform detection on the batteries in the all-round limited working conditions.

  Excellent dynamic response
• 

  The product voltage ranges from low voltage 15V to high voltage 900V, covering solutions within the entire voltage range; The module is highly efficient in both positive and negative directions, maintaining high feedback efficiency of the entire equipment; The output current and voltage present high precision and small ripple, which does not affect the precision of the subsequent DC/DC, thereby maintaining the high precision and more stability of the entire testing equipment; Besides, it is small in size, light in weight and easy to install, which is provided with a reserved operating space for laboratory testing.

  Complete product range, high performance and simple operation
• 

  The product has passed UL, CE and other certifications, which can adapt to all kinds of overseas export needs; moreover, the modular design makes it easy to eliminate the faults and cut overseas operation and maintenance costs.

  The complete certification and modular design lower the overseas operation and maintenance costs
