Jul 4, 2024 · 预计 2023 年至 2032 年,全球户外电源市场将以 14.0% 的复合年增长率增长,到 2032 年市场规模将达到 368.6 亿美元。 这一增长主要是由各种应用中对便携式电源的需求不断
In 2020, 1.7 billion external power supplies (EPS) were in use in the EU27, of which 75% for residential use, on average 6.5 units per EU household. They converted 48 TWh/a of electricity from the 220V mains to the input needed by the powered products.
Since then, the US, European Union, China and other countries adopted both voluntary and mandatory external power supply standards as part of energy conservation legislation. Table 1 shows a breakdown of some of the current voluntary and mandatory standards by region.
If you take a scroll down the page, you will notice that most countries have a well-defined plug and voltage standard. Many Latin-American, African and Asian countries, however, use a motley collection of - often incompatible - plugs and sometimes also the voltage differs from region to region.
At a global level, mandates for power efficiency exist for most consumer electronics and home appliances. External power supplies have had regulations dating back to 2004, when the California Energy Commission created one of the first mandates for efficiency of external power supplies used to power appliances or consumer electronic devices.
In 2020, due to Ecodesign measures, EU27 users saved € 0.9 billion on external power supplies. This is projected to increase to € 1.3 billion in 2030, a 16% saving. In 2030, the annual household expenses for EPS are projected to decrease from € 33 (without measures) to € 28.
All specifications, both EU and US standards, are based on taking an average of 25%, 50%, 75% and 100% of the nominal output power.
The global residential solar storage and inverter market is experiencing rapid expansion, with demand increasing by over 300% in the past three years. Home energy storage solutions now account for approximately 35% of all new residential solar installations worldwide. North America leads with 38% market share, driven by homeowner energy independence goals and federal tax credits that reduce total system costs by 26-30%. Europe follows with 32% market share, where standardized home storage designs have cut installation timelines by 55% compared to custom solutions. Asia-Pacific represents the fastest-growing region at 45% CAGR, with manufacturing innovations reducing system prices by 18% annually. Emerging markets are adopting residential storage for backup power and energy cost reduction, with typical payback periods of 4-7 years. Modern home installations now feature integrated systems with 10-30kWh capacity at costs below $700/kWh for complete residential energy solutions.
Technological advancements are dramatically improving home solar storage and inverter performance while reducing costs. Next-generation battery management systems maintain optimal performance with 40% less energy loss, extending battery lifespan to 15+ years. Standardized plug-and-play designs have reduced installation costs from $1,200/kW to $650/kW since 2022. Smart integration features now allow home systems to operate as virtual power plants, increasing homeowner savings by 35% through time-of-use optimization and grid services. Safety innovations including multi-stage protection and thermal management systems have reduced insurance premiums by 25% for solar storage installations. New modular designs enable capacity expansion through simple battery additions at just $600/kWh for incremental storage. These innovations have improved ROI significantly, with residential projects typically achieving payback in 5-8 years depending on local electricity rates and incentive programs. Recent pricing trends show standard home systems (5-10kWh) starting at $8,000 and premium systems (15-20kWh) from $12,000, with financing options available for homeowners.
