This paper introduces the lack of standard-interface of DC battery in the substation and that varies types of test equipment can not be integrated used. It proposes an integrated standard-interface design Scheme of DC battery

which can be used by varies types of test equipment. The interface is easy to install and maintain and can be connected with the equipment of capacity test

operation parameters test

single battery internal resistance and connection resistance test. It is beneficial for the battery test data comparisons. The paper analyzes the battery test efficiency and reliability between traditional manual and online method finally. Laboratory and field test results show that the method can improve productivity and reduce operational risks.
