Design of Microcontrollers Based Smart Battery Management System Enhancement for Off - Grid Remote Homes
Sylvester Tirones, Raj Kumar
Abstract: Existing battery management system (BMS) for off - grid standalone solar homes are designed to provide management to the batteries especially to measure and estimate the charge level, temperature, health, state of power and to engage computation that protects the battery. Integration of microcontrollers as smart enhancement for monitoring and control of the BMS extends flexibility in the operation of reliable energy distributions to the users. The design also integrates additional functional features to the existing solar photovoltaic (PV) system and communication facilities that cater for deployment of controls that utilizes load management in the BMS. Besides, load management is seen as a vital aspect that manages the power in an off - grid system. Variation of loads which put stress on the battery can be managed through battery selectors that have multiple batteries connection and can be selected upon the capacity of battery and the users desired. It also integrates a demand load controller that prioritizes the loads with reference power setting. Moreover, the need for balance in the energy chain enables the maximizing of incoming charges from the renewable energy (RE) for which the BMS will monitor and control the charges in and out of the battery. In an off - grid PV system, solar has made a substantial stand in generating electric energy for the users, but due to the limitation in solar irradiance and angle of incidence between the direction of the sunlight and PV panel during different times of the day have put challenges for the design of solar tracking system. The existing BMS provides less information to the users especially on - site, remotely and distantly. Therefore, the proposed microcontroller based system enables serial communication to transfer imperative data to be displayed on a graphical user interface (GUI) remotely. The design is proposed to utilize the demand in monitoring and protection of the BMS functions as well for off - grid solar PV system.
