The energy-efficiency of this power conversion process depends heavily on semiconductor technologies. However, when it comes to energy storage, it''s equally important to manage the battery safely and efficiently. For this reason, the battery management system (BMS) is a key component of energy storage systems. Based on dedicated ICs and
In 2003, energy efficiency provisions were introduced into the BCA for housing. In 2005, energy efficiency provisions were introduced for other residential buildings. In 2006, the provisions were expanded to include all other building classifications, as well as enhancing the stringency for houses to a target of 5 stars.
Over the past decade, global installed capacity of solar photovoltaic (PV) has dramatically increased as part of a shift from fossil fuels towards reliable, clean, efficient and sustainable fuels (Kousksou et al., 2014, Santoyo-Castelazo and Azapagic, 2014).PV technology integrated with energy storage is necessary to store excess PV power generated for later use
