Observe how the charge and discharge rates are scaled and why it matters. Charge and discharge rates of a battery are governed by C-rates. The capacity of a battery is commonly rated at 1C, meaning that a fully charged battery rated at 1Ah should provide 1A for one hour. The same battery discharging at 0.5C […]
Learn the key feature of each Li-ion in a summary table. The term lithium-ion points to a family of batteries that shares similarities, but the chemistries can vary greatly. Li-cobalt, Li-manganese, NMC and Li-aluminum are similar in that they deliver high capacity and are used in portable applications. Li-phosphate and Li-titanate have lower voltages and have less […]
Learn how to arrange batteries to increase voltage or gain higher capacity. Batteries achieve the desired operating voltage by connecting several cells in series; each cell adds its voltage potential to derive at the total terminal voltage. Parallel connection attains higher capacity by adding up the total ampere-hour (Ah). Some packs may consist of […]
Discover familiar battery formats, some of which going back to the late 1800s. Early batteries of the 1700s and 1800s developed in Europe were mostly encased in glass jars. As batteries grew in size, jars shifted to sealed wooden containers and composite materials. In the 1890s, battery manufacturing spread from Europe to the United States […]
Safety Issues When Using Drones The most common drone safety issues, next to pilot error are related to battery failures. If you’ve ever experienced battery failure during charging, storage, or operation, then you understand how alarming and potentially dangerous it can be. Over 200 injuries related to drone battery incidents were reported to the U.S. Consumer […]
From: Jack Bayliss You walk into work one morning and find out that a battery system isn’t working. What happens? How much time will you lose trying to fix it? Getting it back online will probably cost money, but how much? When it comes to battery malfunctions, that’s not even the worst-case scenario. What […]
As technology advances, portable energy solutions are becoming more available and more sophisticated. Highly specialized technologies call for highly specialized batteries. Custom OEM batteries can help your business operate more efficiently and increase your profits. Himax has many years of experience in designing batteries for Lead-acid replacement, as well as in other industrial and commercial […]
The energy density of batteries can be displayed in two different ways: gravimetric energy density and volumetric energy density. The gravimetric 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 (W-hr / kg). The volumetric energy density, on the other hand, is […]
Californians do not purchase electric vehicles because they are cool, they buy EVs because they live in a warm climate. Conventional lithium-ion batteries cannot be rapidly charged at temperatures below 50 degrees Fahrenheit, but now a team of engineers has created a battery that can self-heat, allowing rapid charging regardless of the outside chill.
LiHV电池的电压 An L-i-H-V battery is a type of Lithium battery that allows for a higher than normal voltage. The “HV” stands for “high voltage” and it has a higher energy density than standard LiPo batteries. Ordinary LiPo batteries have a nominal voltage of 3.7V and a fully charged voltage of 4.2V. LiFePO4 batteries have a nominal voltage of 3.2V […]
