Embodiment

[0039] This embodiment provides a method for detecting the health of a battery, which is used to detect the health of a valve-regulated lead-acid battery when it is in a floating charge state. Based on the voltage, current, DC internal resistance and capacity of the valve-regulated lead-acid For the health of the lead-acid battery, estimate the capacity coefficient, open circuit voltage and DC internal resistance of the valve-regulated lead-acid battery under the state of floating charge after multiple discharges, and calculate the voltage or capacity ratio of the valve-regulated lead-acid battery, including the following step:

[0040] Carry out several discharge tests on the valve-regulated lead-acid battery, and after each discharge test, charge the battery to keep it in a floating charge state.

[0041] The valve-regulated lead-acid battery needs to be in a floating charge state before each discharge. Therefore, the open circuit voltage V of the valve-regulated lead-acid b...

Abstract

The invention discloses a battery health degree detection method, and relates to the technical field of valve-regulated lead-acid storage batteries. According to the battery health degree detection method provided by the technical scheme provided by the invention, the health degree of a valve-regulated lead-acid storage battery in a floating charge state is predicted based on the voltage, the current, the internal resistance and the capacity of the valve-regulated lead-acid storage battery, and the battery capacity coefficient, the open-circuit voltage value and the direct-current internal resistance of the valve-regulated lead-acid storage battery in the floating charge state after multiple discharge tests are estimated; and the voltage or capacity ratio of the valve-regulated lead-acid storage battery is calculated. By analyzing and assimilating the multi-dimensional data of the valve-regulated lead-acid storage battery, the aged valve-regulated lead-acid storage battery can be effectively identified, and the reliability of the valve-regulated lead-acid storage battery is ensured.

Description

【Technical field】 [0001] The invention relates to the technical field of valve-regulated lead-acid batteries, in particular to a battery health degree detection method. 【Background technique】 [0002] The capacity of the valve-regulated lead-acid battery is represented by AH, which represents the amount of electricity that the outside world obtains from the battery when the specified conditions are met during the actual discharge process of the valve-regulated lead-acid battery. VRLA battery capacity early warning can effectively monitor the working status of VRLA battery and maintain the normal and continuous operation of the system using VRLA battery. Therefore, it is of great significance to study the health of VRLA battery: health Incorrect estimation will affect the effective performance of the valve-regulated lead-acid battery within the capacity range, and will affect the safety and reliability of the valve-regulated lead-acid battery. 【Content of invention】 [000...
