The Rise of Home Energy Storage Systems in the Global Clean Energy Transition
The global transition to clean energy is accelerating, leading to the gradual adoption of energy storage systems in households. A home energy storage system refers to an energy storage system used in residential scenarios. The United States, Europe, and Australia are currently the main markets for home energy storage due to various factors. For most domestic households, the cost issue makes these systems not yet a worthwhile investment. However, for households without access to the grid, photovoltaic systems combined with energy storage batteries can meet daily electricity demands. Next, let’s discuss the specific components of a home energy storage system.
Composition of home energy storage system
Compared to megawatt-hour industrial and commercial energy storage systems and grid-side energy storage, home energy storage systems are much smaller in scale. Generally, home energy storage systems are typically 10kWh or 20kWh. The main components of a home energy storage system include:
Energy Storage Battery Pack:
- Stores electrical energy for later use.
Battery Management System (BMS):
- Ensures the safe operation of the battery pack by monitoring its state (e.g., voltage, temperature, and charge level), balancing the charge among cells, and protecting against overcharging, deep discharging, and short-circuiting.
Inverter Control Integrated Machine:
- Converts the stored DC (direct current) electricity from the battery pack into AC (alternating current) electricity, which is used by household appliances. It also manages the flow of electricity between the battery, the household, and the grid (if connected).
