Energy Storage Power Supply is a device that can store electrical energy and release it when needed, typically consisting of a battery pack, power management system (BMS), inverter, charging module, etc. It is similar to a "large power bank", but with more powerful functions, supporting multiple voltage outputs, supplying power to high-power devices, and widely used in fields such as home backup, outdoor activities, emergency disaster relief, and renewable energy storage.
Core functions
Electric energy storage
Energy is stored through battery packs such as lithium-ion, lithium iron phosphate, lead-acid batteries, and supports charging from various sources such as the power grid, solar panels, and generators.
The capacity range is wide, ranging from a few hundred watt hours (Wh, such as portable power sources) to several kilowatt hours (such as household energy storage systems).
Multi scenario power supply
Communication output: Provides 220V/110V AC power through a built-in inverter, supporting the use of household appliances such as refrigerators and air conditioners.
DC output: Supports USB, TypeC, and car charging interfaces, and can charge devices such as mobile phones, laptops, and drones.
High power output: Some models support power above 2000W and can drive high energy consuming tools such as drills and rice cookers.
Intelligent management
Battery protection: functions such as overcharging, overdischarging, overcurrent, short circuit, temperature protection, etc., extend battery life.
Charge and discharge control: optimize charging efficiency (such as MPPT solar charging), dynamically adjust output power.
Status display: Real time view of battery level, input/output power, and remaining usage time through the screen or app.
Energy Expansion and Grid Connection
Support parallel expansion of multiple devices to increase total capacity (such as outdoor camping or home energy storage).
Some household energy storage sources can be connected to the power grid to achieve "peak shaving and valley filling" or serve as energy storage units for photovoltaic systems.
Main types
Portable energy storage power supply
Lightweight and portable, with a capacity typically ranging from 200Wh to 2000Wh, suitable for camping, travel, and emergency power supply.
Representative brands: EcoFlow, Jackery, Anker.
Home energy storage power supply
Large capacity (5kWh~20kWh), used in conjunction with solar panels to achieve household energy self-sufficiency or reduce electricity bills.
Representative products: Tesla Powerwall, Huawei LUNA, BYD Battery Box.
Industrial/Commercial Energy Storage Systems
The megawatt scale (MWh) is used for grid peak shaving, factory backup power, and uninterrupted power supply (UPS) in data centers.
Emergency power supply
Specially designed for disaster scenarios, with high protection level and long standby time, used for critical facilities such as hospitals and communication base stations.
Application scenarios
Outdoor life: Camping, RV power supply, supporting lighting, cooking, projectors and other equipment.
Home backup: Maintain the operation of refrigerators, routers, and medical equipment during power outages.
Renewable energy integration: storing solar and wind power to solve intermittent power generation problems.
Business and Industry: Reduce peak electricity costs and ensure continuous operation of production lines.
Emergency rescue: Provide temporary power for lighting, communication equipment, and medical instruments at the disaster site.
Technology Trends
Higher energy density: using technologies such as lithium iron phosphate (LiFePO ₄) and solid-state batteries to increase capacity and enhance safety.
Integrated solar energy storage: Integrated MPPT solar controller, directly connected to photovoltaic panels for charging, achieving off grid energy system.
Intelligence and networking: Through remote monitoring through an APP and OTA upgrades, it supports linkage with smart home systems.
Modular design: allows users to expand battery capacity or replace faulty modules as needed, reducing costs.
Bidirectional inverter technology: supports vehicle to grid (V2G) or vehicle to load (V2L), such as electric vehicles as temporary energy storage sources.
Key parameter selection
Capacity (Wh): determines the battery life, which needs to be calculated based on the device power and usage time (for example, 1000Wh ≈ can provide 10 hours of power for 100W devices).
Output power (W): determines whether high-power appliances (such as electric kettles that require over 1500W) can be driven.
Charging method: Does it support solar energy, car charging, and fast charging from mains power (such as charging to 80% in 1 hour).
Cycle life: The battery can be charged and discharged up to 2000 times for lithium batteries and only 500 times for lead-acid batteries.
