Technical Field
The invention relates to the technical field of storage batteries, in particular to a storage battery detection system and a detection method thereof.
Background
At present, storage batteries are widely used as backup power systems in energy storage power stations, communication base stations, electric automobiles, electric locomotives and the like. At each stage of the life cycle of the battery, it is difficult for the existing testing technology to detect the SOH (State of health), SOC (State of charge), and remaining life of the battery, if the critical data cannot be obtained in time, and the storage battery to be replaced cannot be found in time, the potential safety hazard exists, even serious safety accidents are caused; meanwhile, the operation stability of the powered device is greatly disturbed.
Among the existing detection technologies for the secondary battery, the power line carrier communication technology is widely used, and has advantages of reduced wiring harness and low cost. For example, CN103336246B discloses a "device and method for monitoring storage battery", and CN104009268B discloses "a smart battery, a system for monitoring smart battery, and a method for detecting the same". However, most of the conventional transmission paths for the battery detection data need to transmit through a natural path through which the electrolyte flows. When the positive and negative electrode columns are in poor contact with the electrolyte due to aging and corrosion, or insufficient electrolyte, the detection data cannot be acquired or transmitted in real time.
