Emergency Power Supply Must Read: An article that explains in detail the advantages and disadvantages of new energy emergency power sources and traditional fuel generators

Article Source：Investment Information Network | Author：Investment Information Network | Issuing Time：2024.03.27
Portable and stable power support for emergency rescue and emergency backup is indispensable for major natural disasters and production safety accidents. The commonly used emergency power solutions currently include new energy emergency energy storage power sources and traditional fuel generators.

Emergency energy storage power supply is a type of power supply with built-in lithium batteries, which can store electrical energy and is a multifunctional portable energy storage power supply with AC and DC output. A fuel powered generator generates kinetic energy and outputs electricity by burning the fuel in the cylinder.

Both products can provide stable electricity, but each has its own advantages when facing different budgets, needs, and scenarios. How should we choose? The next article will take you to understand the advantages and disadvantages of outdoor emergency power sources and fuel generators.



The comprehensive cost of emergency power supply is lower and more worry free, and the purchase cost of generators is lower and the maintenance cost is higher

Let's first look at the cost aspect and conduct a comparative analysis from the initial purchase cost, operation and maintenance cost, and replacement or upgrade cost.

The initial purchase cost of a fuel powered generator depends on the power level. Small generators only cost a few thousand yuan, while large commercial generators cost hundreds of thousands or even millions of yuan; The installation cost is relatively low, but additional infrastructure construction is required for large systems. The initial purchase cost of emergency power supply is relatively high, ranging from several thousand to tens of thousands of yuan depending on the power capacity and power size. Large industrial and commercial energy storage systems also require hundreds of thousands to millions of yuan, including the battery itself, management system (BMS), inverter and installation costs.

In terms of operation, maintenance, and upgrade replacement costs, the main cost of fuel generators is gasoline or liquefied gas, which varies with frequency of use and fluctuations in fuel prices. But the fuel efficiency is low, especially during non full load operation, there will be waste. In addition, the maintenance cost of fuel generators is high and laborious, requiring regular replacement of oil, filters, inspection and repair of components, etc. In general, the oil of a fuel powered generator needs to be changed after the first 5-20 hours of use, and the oil needs to be changed every 80-100 hours of power generation in the later period. On average, the filter needs to be changed every six months. The service life of fuel powered generators depends on usage and maintenance. Generally, the warranty period for a brand's entire machine is 1 year, and the warranty period for generators is 3 years. The average service life is also about 3 years. Once a fuel powered generator that requires high care is damaged, the cost of replacement is high, especially for large or special application generators.

The main operating cost of emergency power sources is electricity bills, which are relatively lower compared to gasoline fuel costs. High usage efficiency, almost no energy waste, and lower overall operating costs. The maintenance cost of emergency power supply is low, the method is simple, and there is no need to replace oil, filters, and other maintenance. The long lifespan of batteries reduces replacement costs. Emergency power supplies that use lithium iron phosphate batteries generally have a cycle count of 3000 times, especially the lithium iron phosphate emergency power supply from Zhenghao EcoFlow. After 4000 cycles, the battery capacity drops to around 80%, and the usual service life can reach more than 10 years, reducing the need for replacement. And Zhenghao EcoFlow's emergency power supply has a self-developed BMS battery management system, which monitors and manages the operating status and usage efficiency of each battery in real-time through intelligent algorithms. It can effectively improve product performance and efficiency while ensuring safety, and extend service life.

When choosing a power supply, not only should the initial purchase cost be considered, but also the labor cost and replacement cost of later maintenance, as well as the service life. From a comprehensive cost perspective, emergency energy storage power sources are more cost-effective, have a longer service life, and are more worry free.

Emergency power supply has a wide range of application scenarios, and generators are suitable for long periods of no electricity scenarios

In addition to cost, the adaptability of usage scenarios is also an important evaluation of product selection. Emergency power supply has the characteristics of environmental protection, low-carbon, emission free, and silent, and can be used in more scenarios. It can almost cover emergency rescue, disaster relief, municipal construction, film and television shooting, power surveying, industrial and commercial backup power, household backup power, and other scenarios. It is not limited by indoor and outdoor space, and can also be used indoors with peace of mind. Its clean energy attributes are also more in line with the current green ecological concept of society and the national "dual carbon" goals.

And there are many models of emergency power supplies, such as Zhenghao EcoFlow, which has products in various capacity ranges from 0.2 to 15 degrees, with a maximum rated power of 3600W. Different models of emergency power supplies can be matched according to different application scenarios and operation conditions to provide power for various emergency rescue equipment such as emergency communication equipment, lighting equipment, water rescue equipment, drones, surveying equipment, demolition equipment, etc.

Fuel powered generators, on the other hand, are not suitable for quiet environments and enclosed spaces such as enclosed environment rescue, medical power supply, and home backup due to their loud noise and emissions of polluting gases. However, since fuel powered generators generate electricity through fuel, in the absence of a power grid, they are more stable and efficient than emergency power sources that charge through solar energy (000591). However, sufficient fuel needs to be stored or transported, otherwise the solar charging function of emergency power sources is more durable and environmentally friendly.

The number of interfaces for emergency power supply is also more diverse, including national standard 220V five port sockets, USB-C, USB-A, car charging, DC5521 and other interfaces, which can directly charge devices such as mobile phones, computers, and drones. The fuel powered generator only has one national standard 220V five port socket, which needs to be plugged in to power more equipment, and its use is relatively limited. In addition, the fuel powered generator is a pull start, which is cumbersome to operate. If one click start is required, some products may not have this function or require additional payment; Emergency power supplies are all one click start, which is convenient and simple.

Overall, the initial investment cost of lithium iron phosphate emergency power supply is higher than that of fuel generators, but its operation and maintenance costs are lower, and it is environmentally friendly. Long term use has higher economic and environmental benefits. In terms of application scenarios, emergency power supplies are more portable, with rich interfaces, zero exhaust gas, and low noise, making them more suitable for the vast majority of scenarios. Due to its technological updates and wider applicability, emergency power sources have been listed as key promoted equipment in the Action Plan for the Development of Key Areas of Safety Emergency Equipment (2023-2025) released by five ministries. Fuel powered generators have their advantages in requiring immediate high-power output or without grid connection, but their application is greatly limited due to high long-term operating costs, high noise, and environmental impacts.

Electricity is the fundamental guarantee for disaster and accident rescue work, and the selection of power supply equipment is crucial. The above introduces the characteristics of emergency energy storage power sources and fuel generators. You can choose based on specific scenario requirements, cost budgets, and considerations of environmental sustainability.
