With the increase in the power of lithium battery products, the expansion of application areas and the requirements of downstream enterprises to reduce production costs, the requirements for energy saving, detection efficiency and power of the Lithium cell testing system are correspondingly increased. At present, the traditional energy-consuming high-power Lithium cell testing system consumes a lot of electric energy during the charging and discharging process. However, the use of technologies such as energy feedback technology can greatly reduce energy consumption and achieve significant energy-saving effects.
In terms of detection efficiency, the main direction is to optimize the detection process and improve the detection method. Take the representative product of the new energy vehicle field as an example of the electric vehicle power lithium battery. Due to the large power and the large amount of charge and discharge detection of the battery pack, the charge and discharge time is average Up to 4-8 hours; for this reason, the industry has continued to increase investment in research and development of fast charging and fast discharging technology for electric vehicle power lithium batteries, and will be applied to the product development of new charge and discharge detection systems in the future to continue to shorten the battery detection time.
At the same time, with the further improvement of new energy vehicle manufacturing technology, and the rapid development of emerging high-end lithium battery application fields such as robots, civilian drones, and aerospace, the degree of refinement of various indicators such as the estimation of cruising range is increasing. It has stricter quality requirements for lithium battery consistency, battery capacity, battery life and discharge rate, which promotes the continuous improvement of the detection accuracy and stability of the Lithium cell testing system.
