Usability Evaluation Method for VRLA Battery Measuring Equipment

Haifeng Jiang, Shusheng Lin

Abstract


This paper presents a method for evaluating the availability of lead-acid battery test equipment and designs the corresponding evaluation mathematical model. International standard IEC60896-2 specifies the lead-acid battery internal resistance level. Because the internal resistance value is usually micro-Ohm level and the lead-acid battery has special electrochemical characteristics, it’s very difficult to measure it. Until now no authority can officially provides the actual resistance value for a given battery. However, the industry has agreed that the internal resistance will gradually increases during the use of the battery and the performance of the battery has close relationship with the change of the internal resistance, so even if the measurement equipment can not measure the absolute actual resistance, but as long as the battery can be measured a small change in internal resistance, it has a high availability. In this paper, we propose a micro-incremental verification method and a mathematical model to facilitate, accurately and quickly verify whether the battery internal resistance test equipment can accurately and stably measure the internal resistance of the battery, and provide technical verification reference for selecting the battery measuring equipment.
