With the increasing number of battery models and Residential Energy Storage System versions, engineers and designers have always face higher efficiency, power density and reliability needs in system design. It is expected that there are three trends that will have a significant impact on future Residential Energy Storage System design development methods and outlook:

Silicon carbide (SIC) technology • Lower cost per watt

• The system size is smaller and the weight is lighter

• More support frequency

• Magnetic components are smaller

• L for less loss and better heat dissipation (smaller heat sink)

• High power density

• Simplified two -way topology

• higher efficiency

• Material list (BOM) content is less content

• Stability and system reliability

Multi -module method • Repeated use of more and more secondary batteries

• The battery pack is connected to its own two -way power converter

• The output of the series converter to create a high -voltage DC bus

• The current from the battery does not need to be equal

• Voltage output controlled

• higher flexibility

Battery Management System (BMS) • Battery Protection

• Battery monitoring

• Safety Work Area (SOA) wider

• Short -circuit protection, with higher rated peak current current

• Tailoring and opening solutions for application requirements

• More economical solutions, more compact BOM and more effective parallel solutions
