　　602030 lipo battery manufacturers explain battery types and 602030 lipo battery BMS functions

　　602030 lipo battery manufacturers explain battery types and 602030 lipo battery BMS functions. There are many ways to classify batteries. According to battery energy, they can be divided into chemical batteries, physical batteries, and biological batteries. The three core functions of 602030 lipo battery BMS are cell monitoring, state of charge (SOC) estimation and single cell balancing. In this article, 602030 lipo battery manufacturers explain the types of batteries and the functions of 602030 lipo battery BMS

　　What types of batteries are there?

　　1. Carbon battery

　　Primary battery, voltage: 1.5V. Zinc-manganese battery, commonly known as carbon battery. Dry batteries commonly used in daily life. It is the cheapest battery currently available. This kind of battery has low capacity and is prone to leakage. It is currently commonly used in products such as TV remote controls. Common products: No. 1, No. 2, No. 5, No. 7, button type, etc.

　　2. Alkaline batteries

　　Primary battery, voltage: 1.5V. Alkaline batteries are currently the most commonly used batteries. The advantage lies in its long-lasting power, which can be 7 times that of carbon-based batteries. The current output is stable and does not leak. It can be used in instruments and equipment that consume relatively large amounts of power. Common products: No. 1, No. 2, No. 5, No. 7, button type, etc.

　　3. Nickel-cadmium battery

　　Rechargeable battery, voltage: 1.2V. Disadvantages of nickel-cadmium batteries: large size, heavy weight, small capacity, self-discharge, memory effect, and not environmentally friendly. The advantage is: it can be recharged more than 500 times, which is very economical. Resistant to overshoot and over-discharge, easy to use and operate. The internal resistance is small and can discharge large currents, so this product is often used in power tools. Common products: No. 1 (D type), No. 2 (C type), No. 5 (AA), No. 7 (AAA), button type and various non-standard models.

　　4. Ni-MH battery

　　Rechargeable battery, voltage: 1.2V. The disadvantage of nickel-metal hydride batteries and nickel-cadmium batteries is that they cannot be discharged at high currents (there are already factories producing nickel-metal hydride batteries with high current discharges). The advantage is that the capacity of the same volume is more than twice that of nickel-cadmium, the memory effect is small, and it is pollution-free and is called a green battery. Common products: No. 1 (D type), No. 2 (C type), No. 5 (AA), No. 7 (AAA), button type and various non-standard models.

　　5. Lithium-ion battery

　　Voltage: 3.7V. Lithium-ion battery shells include steel shells and aluminum shells. Aluminum shells have 10%-15% higher capacity than steel shells. Advantages: small size, high capacity, and high voltage. The shapes include cylindrical, square, and special shapes. Commonly used in mobile phone batteries, PDA batteries, laptop batteries.

　　6. Lithium polymer battery

　　Voltage: 3.7V. Comparison between lithium polymer batteries and lithium batteries: The outer packaging is aluminum-plastic packaging, which is different from the metal casing of lithium ions. Thanks to flexible packaging technology, thinner batteries can be produced. The shape can be changed at will. Light weight, higher capacity, small internal resistance, and supports large current discharge. Commonly found in high-end mobile phone batteries, laptop batteries, various power tools and model batteries.

　　602030 lipo battery BMS function introduction

　　1. Battery protection is similar to PCM, including overcharge, over-discharge, over-temperature, over-current, and short-circuit protection.

　　2. Energy balance. Since many batteries are connected in series, the entire 602030 lipo battery pack will eventually show great differences after working for a certain period of time due to the inconsistency of the cells themselves, the inconsistency of the operating temperature and other reasons. The life of the battery and the use of the system have a huge impact. Energy balancing is to make up for the differences between individual cells and perform some active or passive charge or discharge management to ensure the consistency of the 602030 lipo battery and extend the life of the battery.

　　3. SOC calculation, 602030 lipo battery power calculation is a very important part of BMS. Many systems need to know the remaining power more accurately. Due to the development of technology, many methods have been accumulated for SOC calculation. Those with low accuracy requirements can judge the remaining power based on the battery voltage.

　　In general: 602030 lipo battery BMS is a layered, graded and unified management of single cells, battery packs and battery stacks, and various parameters of the battery (single, pack, stack) according to the characteristics of each layer and level. Calculate and analyze the operating status to achieve effective management such as balancing, alarming, and protection, so that each battery pack can achieve equal output and ensure that the system reaches the best operating status and longest operating time.
