Which brand of 24V smart lithium battery is right?

There are many brands of 24V smart lithium batteries on the market. Among the many brands, Karku is relatively famous. They recently launched a 24V intelligent lithium battery for heavy-duty trucks, which has attracted a lot of attention, mainly because. of its capacity. It is large, has a long lifespan, and most importantly, has ultra-high safety performance. It uses special quality low temperature customized batteries, which have multiple protection functions such as ultra-low temperature and anti-puncture. , high temperature resistance and anti-collision, making safety safer

Generally lithium batteries 24 volt iron phosphate batteries have a higher voltage and higher energy density than 12 volt batteries can provide more power. Therefore, inFor scenarios requiring higher voltage or power, it may be more appropriate to choose a 24-volt lithium iron phosphate battery.

However, this does not mean that 12-volt lithium iron phosphate batteries are completely inferior to 24-volt batteries. In some cases, a 12-volt battery may be better suited to specific needs. For example, without requiring particularly high voltage or power, a 12-volt battery could be lighter and easier to install and maintain.

Therefore, when choosing which type of lithium iron phosphate battery to choose, you should consider factors such as specific application scenarios, equipment requirements and budget . In some specific situations a 12 volt battery may be more suitable, while in other situations a 24 volt battery may be advantageousse.

The 24V ternary lithium battery from Pacific Automotive Network is made up of 7 strings. Although electric vehicle batteries rarely discharge at 1C, the capacity of their cells is often more than 20ah, and a current of 0.2C can reach 4A.

1: It’s very simple. Connecting in series increases the voltage and connecting in parallel increases the capacity. The standard voltage of ternary lithium is 3.7 V. When fully charged, it is 4.2 V. Three strings are 48 V, four are needed. three strings. However, lead-acid electric vehicles When the battery is fully charged, 58V is the best, so the lithium battery also needs to reach about 58V, so 14 strings are needed to reach 58.8V, 14 times iron. lithium is fully charged at around 3.4V, which requires four strings of 12V, and 48V requires 16 strings. By analogy, 60 V requires 20 strings of the mSame model and same capacity. Two 10 Ah batteries connected in parallel make 20 Ah to 48 V ternary lithium. +14 10ah batteries. The last 14 series connected in parallel form a 48v20ah lithium battery Answer

2: It's actually very simple. For example, 48 volts refers to voltage. Ternary lithium batteries generally refer to 48. divided by 3.7. This way, thirteen and fourteen strings are both counted as 48 volts. Ten three strings are charged with a 54.6 volt charger and fourteen strings are charged with a 58.8 volt charger. As for 20 Ah, it refers to the capacity of the battery. If a single 18650 battery cell has a capacity of 2000 mAh, it will be 2 Ah each. Ten cells together will be 20 Ah and the entire battery will be. 14 String multiplied by 10 cells = 140 cells.

The same goes for 60 volts. Usually 16 to 17 strings are counted as 60 volts. For example, at 60 volts and 20 amps, the capacity of a single battery cell is 2000 mA, i.e. 16-17 times 10, 160-170 cells. It should be clear from here that the total voltage of an iron-lithium battery is divided by 3.2. For example, a 48 volt iron-lithium battery refers to 15-16 strings. The algorithm is the same, except iron-lithium has several others. Strings of batteries as ternary lithium. Another. The charging voltages of lithium iron and ternary lithium are also different.
