How to assemble 48v lithium battery pack

Lithium ion battery is a rechargeable battery, which mainly relies on lithium ions to move between the positive and negative poles to work. Traditionally, the process of lithium ions entering the positive electrode material is called embedding, and the process of leaving is called  to take off the plug. Lithium ions get into the cathode material process is called insertion, leaving the process is called detachment. Like all chemical batteries, lithium-ion batteries are made up of three components: a positive electrode, a negative electrode, and an electrolyte. The electrode materials are all lithium ions that can be (embedded)inserted/off (take off). The voltage of lithium ion battery is 3.6~3.7V.

Lithium-ion polymer battery is nickel metal hydride batteries (NiMH) (NiCdbattery) modified by nickel-cadmium batteries, the absorbing hydrogen to make the metal instead of cadmium (Cd).It provides with same price higher than the nickel cadmium battery electric capacity, less obvious memory effect, and low environmental pollution (excluding toxic cadmium).The recycled efficiency is better than lithium ion batteries, known as the most environmentally friendly batteries. But when compared with lithium ion battery, it has higher memory effect. Older nimh battery has higher self discharge reaction, the new nimh battery has a fairly low self discharge (with alkali electricity), and can work under low temperature (20 ℃). Nickel-metal hydride battery has higher output currents than carbon zinc or alkaline battery and is relatively suitable for energy-intensive products. Some special models even have higher output currents than nickel-cadmium battery.

Lithium ion polymer battery is also known as lithium polymer battery, lithium polymer battery. It is a rechargeable battery with colloidal polymer as electrolyte. Avoid lithium ion battery under high temperature easy safety problems. Compared with li-ion batteries, li-polymer batteries have the following characteristics:

1. No battery leakage problems, its inside the battery does not contain liquid electrolyte, the use of colloidal solids.

2. The battery can be made into thin cells: the thickness can be thin to 0.5 mm.

3. The battery can be designed into a variety of shapes, maximum bending around 90°Nimh batteries.

4. The battery can be made into a single high voltage: liquid electrolyte battery can only with the number of cells in series with high voltage, and the polymer batteries as there is no liquid itself, can be made within the single star multilayer combination to achieve high voltage.

5. The capacity will be more than double that of the same size of lithium ion batteries.

Lithium-ion polymer battery voltage is 3.6 ~ 3.7 V.

Lithium iron phosphate battery has high environmental adaptability, which is reflected in its high power bearing capacity, low temperature resistance, strong adaptability and low self-discharge probability, which greatly extends the range and field of use of the battery. Its green environmental protection is reflected in the production and use of lithium battery scrap process, does not contain or produce any lead, cadmium and other harmful metal elements and substances.

Lithium iron phosphate (molecular formula: LiMPO4, English name is Lithiumironphosphate, also called the lithium iron phosphate, lithium iron phosphate, referred to as "the LFP), is a kind of lithium ion battery cathode material, also known as lithium iron phosphate batteries. It does not contain cobalt and other precious elements, the price of raw materials is low and phosphorus, lithium, iron in the earth's rich content of resources, there will be no feeding problem. Its working voltage (3.2 V), moderate large capacitance (170mah/g), high discharge power, can fast charge, long cycle life, high stability under high temperature and high temperature environment. Lithium iron phosphate battery voltage is 3.2 ~ 3.3 V.

The battery

Lithium battery assembly has professional production of lithium ion battery equipment and supporting facilities, to provide technical training for business, with such equipment, can easily undertake a variety of lithium electric processing, customized lithium ion battery. The lithium ion battery using has penetrated the today's industries, environmentally friendly vehicles, electric bicycle, mobile phone batteries, computer batteries, camera batteries, led lamp lighting battery,special and other fields. Introduction of constant force lithium battery assembly lithium battery assembly of mechanical and electronic equipment, professional production of various types of lithium ion battery, easily pried open a new wealth for you.

Lithium battery electric vehicles are more and more accepted by consumers because of their gorgeous and concise appearance. Why so good is a lithium-ion electric car? Is it really as good as they say? Now in the market, the most sold are still lead-acid battery electric vehicles, but a lot of areas began to introduce lithium battery electric vehicles. Lithium battery electric vehicles, as the name suggests, is simply to replace the lead-acid lithium battery. How about lithium batteries for electric cars compared to lead-acid batteries? Does it really have the enterprise, dealer says so good? Now vigorously advocate energy conservation, green, environmental protection. Can it really spread? Many questions remain unanswered. When it comes to electric lithium battery views are very consistent, "is lighter than lead-acid batteries, lithium battery life is long, but the price is very expensive". Every time reporters ask more details, what are the advantages? Again, no one seemed able to answer. Lithium battery electric cars advantage: Lithium batteries have long life, light weight and small size. The power performance of lithium battery electric bicycle and lead-acid battery (simple electric bicycle) is about the same, charge 6~8 hours, according to the battery capacity can run 30~45 km, the weight of lead-acid battery is only about 1/5, the most important advantage of lithium battery electric bicycle is long life.

1, high voltage: The voltage of a single battery is 3.6v -- 3.9v, which is equivalent to the series voltage of three nickel-cadmium or nickel-metal hydride batteries.

2, small amount of self-discharge: Storage for a month, the discharge of less than 10%, indicating that it can be stored for a long time.

3.No memory effect: Lithium batteries don’t have the so-called memory effect of nickel-cadmium batteries, so lithium batteries don’t need to discharge before charging.

4. Long service life: Under normal use, the capacity of 500 cycles of charging and discharging decreases by less than 20%. For low-power lithium batteries, it will exceed the service life of electrical appliances.

5. Quick charging: Lithium-ion batteries can usually be charged at 0.5 to 1 times the current. Shorten the charging time by 4-5 hours.

6. No pollution to the environment: Lithium ion battery does not contain cadmium, lead, and other metal elements, is the current green battery.

7. Wide working temperature range: The normal operating temperature is -25 -- 45 degrees. It is expected to expand to -40---70 degrees through the improvement of electrolyte and positive electrode.

8. Can be directly used in parallel or in series.
