Yichun Topwell Power Co., Ltd

Today,   Yichun Topwell Power Co., Ltd   will show you how to calculate the data of some common solar power generation systems, and use this to choose suitable accessories. First of all, we need to understand some basic circuit knowledge, such as Ohm's law (that is, voltage = current * resistance), and the calculation formula about power: Current (A) x Voltage (V) = Power (W) Current × power consumption time = battery capacity Ah Simply understand that 1AH is 1A discharge for 1 hour After having these knowledge backgrounds, we also need to know some conditions: 1. Load power and voltage 2. Working hours per day 3. Use (installation) location 4. Sunshine time Example 1: Assume that the required load requirement is 48W12V, and it works 10 hours a day. If it is necessary to ensure that the load can still work normally for 3 consecutive cloudy days. How to match the solar system? (Place of use: Fujian, 4 hours of standard sunshine) calculation process: ⑴ Calculate the power of sol...

  What is a home energy storage system? getting more popular? The   home energy storage system  mainly stores the excess power generated by solar panels in the battery pack, which is convenient for the family to use at any time. During the day. When the sunlight is normal, the solar photovoltaic modules generate more energy, and the battery can store it to ensure the electricity at night  or  another cloudy or rainy day. Also because the battery can optimize the use of electricity, it can ensure the effective operation of the entire home system. At the same time, if there is a sudden suspension of household electricity consumption, for example, if the desktop computer drawings cannot be saved in time in the future, the fresh food in the refrigerator will melt and may deteriorate, etc., but with a home energy storage system, it can maintain continuous power consumption under such circumstances. performance and extremely short response times. The home energy stora...

  In 2022, Europe's battery energy storage installed capacity will be 4.5GW, and it is expected to reach 95GW by 2050 An aerial view of the largest battery energy storage system in continental Europe, a 50MW/100MWh battery energy storage system located in Wallonia, Belgium. Image: CORSICA SOLE According to LCP Delta and Aurora Energy Research, battery energy storage capacity in Europe reached 4.5GW last year and could reach 95GW by 2050. In a separate statement a few weeks ago, LCP Delta said that around 1.9GW of grid-scale battery storage was installed across continental Europe, including the UK, last year. LCP Delta said in the seventh edition of the "European Energy Storage Market Monitor" (EMMES), published in cooperation with the European Energy Storage Association (EASE), that it is expected that at least 6GW of battery  energy storage systems  will be installed in continental Europe by 2023. According to Aurora Energy Research, by 2050, Europe is expected to ...

18650 batteries are a popular choice among industries requiring high-performance batteries, with the ability to store a large amount of energy in a compact size. 18650 batteries are a type of lithium-ion battery that can be used in various devices such as flashlights, laptops, power banks, and electric vehicles. They have become a practical and cost-effective solution, but before you get your hands on them, there is some essential information you should know. 1.  What is an 18650 Battery ? You might be wondering what the number 18650 means. Well, 18650 batteries get their name from their dimensions. The first two digits are the diameter, while the last three digits are the length, expressed in millimeters. Therefore, an 18650 battery has a diameter of 18mm and is 65mm long. They usually have a capacity of 2,500mAh, which means they can sustain discharge rates of 2.5 amps for one hour. 2. Advantages of 18650 Batteries 18650 batteries are a popular choice due to their long lifespan, ...

Compared with other high-energy secondary batteries such as Ni-Cd batteries, Ni-MH batteries, lead-acid batteries, etc.,   Li-ion   batteries   have significant advantages in performance, which are mainly reflected in the following aspects. (1) High working voltage Using carbonaceous lithium intercalation compounds such as graphite or petroleum coke instead of metal lithium as the negative electrode will reduce the battery voltage. However, due to their low lithium intercalation potential, the voltage loss can be minimized. At the same time, selecting a suitable lithium intercalation compound as the positive electrode of the battery and selecting an appropriate electrolyte system (determining the electrochemical window of the lithium ion battery pack) can make the lithium ion battery pack have a higher working voltage (4V), which is much higher than in aqueous system batteries. (2) Large specific capacity Although the replacement of metal lithium with carbonaceous materia...
