What are the classifications of tram batteries?

The types of electric vehicle batteries include lead-acid batteries, nickel-metal hydride batteries, lithium iron phosphate batteries, and ternary lithium batteries.

1. Lead Acid Battery

As the cheapest type of battery, it is the most commonly used battery in our fuel. the vehicles. Electrical systems such as headlights and air conditioners are powered by this, which is the battery that we need to replace within 2-3 years. It also serves as a power source for the electrical system in some special usage scenarios.

2. Nickel-metal hydride battery

Compared to lead-acid batteries, this type of battery only needs half the weight to reach the same level as Lead-acid batteries have a good better capacity than lead acid batteries in terms of performance. The vehiclesToyota hybrids generally use this type of battery. But it also has its own drawbacks. It will inevitably cause attenuation during use, and excessive charging and discharging will aggravate this problem.

3. Lithium iron phosphate battery

The biggest advantage of lithium iron phosphate battery is undoubtedly its cheaper price. The reason is also very simple, because it is very simple. Much of the material is iron, and compared to ternary lithium batteries using precious metals, the capacity density is lower and the low temperature performance is significantly worse. If placed in the frigid northeast, its cruising range will be reduced. be reduced. Half doesn't matter.

4. Ternary lithium battery

Ternary lithium battery can be said to be the most commonly used battery ins imported models, whether BMW or Tesla brands. like La or Renault currently use ternary lithium batteries in electric vehicles. It is characterized by high energy density, which can generally reach more than 6 times that of lead-acid batteries.

In terms of general classification, there are currently two types of electric vehicle batteries: lead-acid batteries and lithium batteries. From a safety perspective, lead acid batteries are better than lithium batteries. From an energy density perspective, lithium batteries are better than lead acid batteries. In terms of lifespan, lithium batteries are better than lead acid batteries. In terms of price, lithium batteries are more expensive.

In addition, lithium batteries can also be divided into lithium iron phosphate batteries, ternary lithium batteriess and lithium manganate batteries based on different materials. Lithium batteries are made of different materials and have different characteristics. The general summary is as follows:

Safety: lithium iron phosphate>lithium manganate>lithium ternary;

Lifespan: Lithium iron phosphate>lithium ternary>lithium manganate;

p>

Capacity: ternary lithium>lithium iron phosphate>lithium manganate;

Price: lithium iron phosphate>ternary lithium>lithium manganese acid.

Therefore, whether it is comparing lead-acid batteries with lithium batteries, or comparing lithium batteries with different materials, they all have their own advantages and disadvantages, and you can choose the most suitable one according to your actual needs. needs of electric vehicles.
