Explore and analyze the thermal power of Li- ion cells and battery packs (part-1)
Jul , 04 2022
Temperature is very important for lithium- ion batteries. Low temperature will reduce the electrical performance of lithium- ion batteries (capacity, rate performance), but it can improve the storage life of lithium- ion batteries. High temperature can improve electrical performance (capacity, rate performance), but It will reduce the stability of the electrode/electrolyte interface and cause a ra...

Some FAQ about the Lithium batteries for UPS
Apr , 06 2022
What are the primary benefits of switching to lithium based UPS batteries? The most common reason cited is the significantly longer service life. Lithium also provides a greater cycle life (the number of charge/discharge cycles ranges from extends into the thousands, versus approximately 500-600 for VRLA batteries), as well as a longer warranty. Furthermore, the lighter weight and smaller footprin...

How to do the SOC-OCV test for Lithium batteries?
Apr , 06 2022
OCV is very important for SOC estimation. It is a function of cell SOC and temperature. There are two methods to measure the OCV, namely coulomb titration and voltage relaxation. The former discharges and charges the cell with the same low current while measuring the terminal voltage. The OCV is defined as the average value of the charge and the discharge terminal voltage. The latter determines th...

RV Battery Guide: Choosing the Right Travel Trailer Battery(part-2)
Feb , 12 2022
Once you’ve picked what type of travel trailer battery you’ll use in your RV, it’s time to figure out exactly what your battery bank will look like. The voltage you’ll need is 12V, but the amp hours vary according to how many components you need to power, and for how long. For most travel trailers, you have two choices. 1. 1.Two to six 6-volt batteries 2. 2.On...

RV Battery Guide: Choosing the Right Travel Trailer Battery(part-1)
Feb , 12 2022
Travel trailers don’t move on their own. You “trail” them behind a truck. So they don’t need a battery, right? Wrong. They have essential electrical components that keep you and other motorists safe on the road. Namely, electric wheel brakes. These must be functioning if you want to stay on the right side of the law. That’s why you need a travel trailer battery to power them. But don’t forget abou...

What is Battery Energy Density?
Feb , 12 2022
Energy density is the measure of how much energy a battery contains in proportion to its weight. This measurement is typically presented in Watt-hours per kilogram (Wh/kg). A watt-hour is a measure of electrical energy that is equivalent to the consumption of one watt for one hour. Power density is the measure of how quickly the energy can be delivered, rather than how much stored energy is availa...

What are the major factors needs to be considered in vehicle application Lithium battery?
Feb , 12 2022
Lithium batteries are lightweight and provide higher energy density than lead-acid or nickel–metal hydride (NiMH) batteries, creating a demand for them in electric vehicles (EV), energy storage, and consumer electronics. Compared to NiMH batteries, lithium batteries have a 50 percent greater capacity in watt-hours per kilogram (w-h/kg). The EV industry is demanding higher-efficiency batt...

How LFP battery aging is different from SLA battery?
Feb , 12 2022
Aging is an unavoidable process caused by side reactions present in all electrochemical devices including battery cells. It may result in significant changes of capacity and resistance of a device over time and must, therefore, be considered in the system layout phase (e.g., necessity of over-sizing initial capacity) as well as in the system operation phase (e.g., adapting maximum allowed cell dis...
