An ‘Online’ Battery Management System has been developed to provide necessary battery data via the internet in real time. The hardware and software design presents the data to ensure a quality service when leasing and renting batteries for motive power applications. Through several years of field experience with this system and the integration of new features and an improved reporting system, the product has been enhanced for use in solar applications and energy storage. The software is compatible with any common battery chemistry, e.g., lead–acid, lithium-ion, and nickel–cadmium. The presentation describes the innovative design of a wireless e2BMU version and the high flexibility it offers to ensure the capture of vital basic battery information through an internet website. The battery data is continuously monitored, stored and analysed by dedicated software that is able to take automatically the necessary actions to ensure reliable and safe battery operation. The data is sent periodically to a web server, through the latest state-of-the art technology in wireless communication. The field experience and results demonstrate the huge advantages to be gained through using this battery monitoring technology. In particular, the high flexibility of the hardware and the software makes the system an ideal product for the new emerging market of the storage for solar energy.
