Outdoor Power Station opens up a new high-growth track
1. Performance advantages of outdoor power supplies
Outdoor power supply, also known as portable energy storage power supply, full name is Portable Energy Storage (PES), usually refers to backup power supply or emergency power supply that weighs no more than 18kg.
Outdoor power supplies generally have built-in high-energy-density lithium-ion batteries, with long cycle life, light weight and easy portability, and their overall performance is more stable and reliable, and they have the characteristics of easy operation, low noise, and good maintenance, which can better meet outdoor power consumption. Demand.
In addition, the outdoor power supply has a multi-function output interface, AC output, USB output, car charger interface output, users can use in different scenarios, the use experience is more convenient.
2. Application scenarios of outdoor power supply
The downstream application layer of outdoor power supply is very extensive. In addition to outdoor camping, it also involves flood prevention, medical rescue, outdoor construction, field exploration, offshore operations, mobile booths, outdoor live broadcast, film and television production and other fields. It is used in mountainous areas, pastoral areas, and caravans.
3. Composition and materials of outdoor power supply
The outdoor power supply is an outdoor emergency power supply that is composed of chargers, inverters, storage batteries, isolation transformers, switch switches and other devices to invert DC power into AC power.
Most of the outer shell materials of outdoor power supplies use high-strength engineering plastics, which are not only anti-fall and anti-vibration, but also have strong fire and rain resistance. The internal material is a large-capacity ternary lithium battery pack, which is small in size, light in weight and high in power.
The outer shell of the outdoor power supply is generally made of PC or PC+ABS fire-retardant materials, which are characterized by safety, lightness, high temperature resistance, and effectively avoid electric shock and leakage risks. But compared with metal materials, its hardness is insufficient, so it is easy to scratch.
As the application scenarios of outdoor power supplies become more and more extensive, the requirements for materials are more stringent. The performance tests of materials include salt spray test, double 85 test (1000 hours), low temperature impact test, etc., which require high material performance. .
The general fireproof PC/ABS material sometimes cracks in the outdoor environment, and a weather-resistant material 923X launched by Sabic can solve this problem well. A certain energy storage project done by the world's top 5 solar solution company uses Sabic PC 923X, which is resistant to low temperature, chemical corrosion, fire resistance, and high flow, which can withstand up to 1500 hours of double 85 test and salt spray test At the same time, because it contains siloxane segments, it can better eliminate the internal stress of the product and successfully solve the problem of product shell cracking.
Product unit weight: 4.3kg
Through testing, it is found that Sabic’s PC 923X has better weather resistance and low temperature resistance than standard PCs, and can better meet the long-term outdoor use requirements of the product.
At present, many outdoor power supplies on the market can also be used with solar panels to achieve continuous power supply, so that there is electricity when there is light. In the absence of mains power supply, high-efficiency monocrystalline silicon solar panels can increase the circulating power supply capacity of outdoor power sources, creating a clean, continuous, safe, reliable, and efficient environment-friendly power plan.
4. Market demand and supply of outdoor power supplies
In recent years, the fierce heat of the new energy automobile industry has stimulated the development of lithium batteries, and the production cost of outdoor power sources has been greatly reduced. Energy storage technology represented by lithium batteries has begun to replace bulky fuel generators. With the introduction of the goal of "carbon peak and carbon neutrality" this year, more people are paying attention to low-carbon, environmentally friendly and green travel, and the demand for new outdoor power sources is also rapidly erupting.
In addition, in the context of the tight power supply, power rationing notices have recently been issued in many places across the country, and the topic of "power rationing" and "power outage" has sparked discussion on the Internet. The lighting, heat preservation, and cooking of modern urban life are inseparable from power support. Power outages will directly affect people's daily life. Many families purchase outdoor power supplies for emergency situations, which further drives the market demand for outdoor power supplies.
