Why are these batteries more expensive? “” What is the size of these batteries? “” What is the lifespan of these batteries? “These are some common questions raised by APC UPS and energy storage owners. As the entire profession gradually transitions from valve regulated lead-acid batteries to lithium batteries, these questions have become increasingly important and chaotic. The intention of this article is not to teach you how to choose or plan a battery system, but to introduce some key factors that determine battery selection. Mastering these common sense can also help you prepare in advance for discussing plans with suppliers, especially when you have to weigh and choose between many plans. Wise battery decisions can help optimize solution plans and bring long-term value.
As the APC UPS system transitions from valve regulated lead-acid batteries to lithium batteries, we must grasp the correct functional standards for evaluating batteries to ensure the selection of the best solution plan for a specific application scenario. Although the planning and chemical composition of battery cells vary greatly, there are two commonly used types of lithium-ion batteries, which have vastly different characteristics and can be divided into energy batteries and power batteries. Although most APC UPS systems use power batteries, what we often see in mass media are parameters and standards related to energy batteries. Most news reports on batteries mainly focus on energy battery systems, such as newly launched electric cars constantly breaking endurance records, energy storage systems extending endurance time, and energy battery system costs continuing to decline. The excessive exposure of energy batteries has led to confusion in the market regarding the price and functionality of power battery systems.
Although the power battery system is not as favored by the news media as energy batteries, it also has various applications. The UPS system is one of them, but they are widely used in hybrid and micro hybrid cars (also known as reducing total speed), cordless power tools, car starter batteries, and battery jump start devices. The UPS battery system is generally designed for use in high-power, short-term discharge applications. However, the traditional application scenario of APC UPS is to supply backup power to the load in the event of a power outage. However, due to the increasing energy efficiency of lithium-ion batteries, their operating time has been continuously extended, and some emerging APC UPS application scenarios have emerged. These APC UPS applications aimed at energy conservation include peak shaving, demand response, generator replacement, peak shaving, and frequency regulation. UPS uses various types of power and energy batteries in various application scenarios, but the most crucial is to use an optimized battery system that matches the application. The optimization of batteries is extremely important for all battery powered systems, whether it is small portable electronic devices or large electric, grid level energy storage systems.
