Title: Performance of battery charge controllers: An interim test report

Abstract

The performance of battery charge controllers and their effects on the system are a critical concern for stand-alone photovoltaic systems with battery storage. Many types of charge controllers are being marketed today, and designers need to understand more about their performance and compatibility with different kinds of batteries and systems. This paper describes the evaluations and selected interim test results from eight different models of small (approx. 10 amps) charge controllers. They are being subjected to a comprehensive test program including thorough electrical characterizations at selected temperatures, photovoltaic inputs and load levels. After electrical characterizations, the charge controllers are divided into concurrent evaluation paths. One path consists of side-by-side operational systems tests in which the charge controllers are installed in identical stand-alone PV systems. The other path consists of continuous environmental and electrical cycling in which the controllers are subjected to programmed electrical inputs, temperatures, and relative humidities. Recharacterizations of all controllers are addition, selected custom tests are performed on identical models to determine response to transients, installation issues and system compatibilities. The data presented here include measured electrical characteristics of the controllers, temperature effects, operational performance, and interface measurements at the array, battery and load. 8 refs., 9 figs.,more » 4 tabs.« less
