Title:
INTERNAL RESISTANCE DETECTION DEVICE AND DETECTION METHOD FOR STORAGE BATTERY, AND STORAGE BATTERY STATE MONITORING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/040778
Kind Code:
A1
Abstract:
An internal resistance detection device and detection method for a storage battery, and a storage battery state monitoring system. The detection device (100) comprises: a discharging unit (101), connected to a storage battery (105), and set to discharge the storage battery (105), wherein a discharging current is within a pre-set range; a discharging control unit (102), connected to the discharging unit (101), and set to repeatedly control the conduction of the discharging unit (101) and close same after a pre-set time, and to perform pulse discharging on the storage battery (105) a plurality of times; a data collection unit (103), respectively connected to the storage battery (105), and set to acquire, in real time, a current value and a voltage value during the process of performing pulse discharging on the storage battery (105); and a data processing unit (104), connected to the data collection unit (103), and set to calculate an internal resistance of the storage battery (105) according to the voltage value and the current value, and the number of times that pulse discharging is performed. On the premise of ensuring a lower degree of damage caused by discharging to the storage battery (105), the technical solution enhances the authenticity and accuracy of the internal resistance measurement of the storage battery (105).
