48v lithium ion battery 100ah price？To answer the question about the price of lithium batteries, we should first find out the main factors that affect the price

1、 The price of 48v 100ah lithium battery mainly consists of:

It is composed of three parts: the electric core, the protective plate and the shell. At the same time, due to the power consumption and current of the electrical appliances used, the selection of the materials of the connecting pieces between the electric cores (conventional nickel pieces, formed nickel pieces, copper nickel composite pieces, jumper pieces, etc.) will affect the cost. Different connectors (such as special plugs, ranging from a few yuan to thousands of yuan) may also have a greater impact on the cost. In addition, different PACK processes will also affect the cost.
2、 Selection of electric core
The selection of battery cells with different material systems will affect the price of lithium batteries. According to the different cathode materials, lifepo4 lithium 48v battery will have multiple material systems of cells, such as lithium manganate (3.6V), lithium titanate (2.3V/2.4V), lithium cobalate (3.7V/3.8V), lithium nickel cobalt manganate (commonly known as ternary, 3.6V), lithium iron phosphate (3.2V), etc.
3、 Demand and Design of Lithium Battery PCM
PCM design can be divided into protection board, communication and BMS.
Protection plate: including overcharge, over discharge, over-current and short circuit protection, etc. The over temperature protection can be added according to the product demand.
Communication: The communication protocol can be divided into RS485, RS232, CANBUS, etc., as well as electricity display, which can be indicated by the power meter and LED.
BMS: It is called the battery management system, which is mainly used to intelligently manage and maintain each battery cell, prevent overcharge and overdischarge of the battery, extend the service life of the battery, and monitor the status of the 48 volt lithium ion battery. Its main functions include: real-time monitoring of battery physical parameters; Battery state estimation; Online diagnosis and early warning; Charge, discharge and pre charge control; Balance management and thermal management, etc. The secondary system is mostly used in electric vehicle batteries.
4、 Demand and design of lithium battery shell
1. The design of lithium battery shell can be divided into: PVC heat seal, plastic heat seal, metal PVC heat seal: what kind of shell packaging form is used for the external part of the battery pack mainly depends on the specific needs of customers. For the packaging form of PVC heat seal, it is generally applicable to the case that the number of cells in series is small and the overall weight is light (≤ 2kg).
2. Plastic: The plastic shell is used. It is mainly because after the shaping of different battery packs, the shells involved may need to be molded, and the mold cost is a large expense. For example, in the early stage of development, if the product is not shaped, the prototype shell can be used for proofing (the strength of the prototype is not as strong as the strength of the material after the shaping). Different requirements for the shell material and process (especially with the requirements of three proofing) will also affect the cost.
3. Metal: The metal shell is the same as the plastic shell. Before the product is finalized or the quantity demand is small, it is recommended to use sheet metal for sample preparation. This is mainly because the sample preparation and delivery time is short. If the batch is large, it is also recommended to open the mold. For metal shells with waterproof grade requirements, the cost will also be greatly affected, and for metal shells with special materials (such as titanium alloy), the cost will be higher.
At present, there are two mainstream battery technology routes, lithium iron phosphate battery and ternary lithium battery. Although these two types of batteries compete in many application fields, they focus on the competition in the field of new energy vehicles, because this is the largest lithium battery application scenario in China. Since there must be competition, there must be a comparison because of the large energy density and much smaller weight, Light weight and small space consumption determine that the new energy vehicles with ternary lithium batteries consume less power, so they have faster speed and stronger endurance.
