Nickel Metal Hydride No. 5 battery

Introduction to BMS Nickel Metal Hydride No. 5 battery management system and working principle

Nickel Metal Hydride No. 5 battery BMS management system is not dispensable as some battery manufacturers say, but must be there. The Nickel Metal Hydride No. 5 battery management system can ensure the safe use of power Nickel Metal Hydride No. 5 battery packs and is the primary task of lithium power battery management system. What is BMS Nickel Metal Hydride No. 5 battery management system? Battery management system BMS is an important component of electric vehicle power battery system. On the one hand, it detects, collects and preliminarily calculates the real-time status parameters of the battery, and controls the on-off of the power supply circuit according to the comparison relationship between the detection value and the allowable value; on the other hand, it reports the collected key data to the vehicle controller, receives the instructions of the controller, and coordinates with other systems on the vehicle. Nickel Metal Hydride No. 5 battery management system, different types of batteries, often have different requirements for the management system. Principle of BMS power Nickel Metal Hydride No. 5 battery management system: Nickel Metal Hydride No. 5 battery management system (BMS), by detecting the status of each single battery in the power battery pack to determine the status of the entire battery system, and according to their status, the power battery system is controlled and adjusted accordingly and the strategy is implemented, so as to realize the charge and discharge management of the power Nickel Metal Hydride No. 5 battery system and each single battery to ensure the safe and stable operation of the power battery system. The topological structure of a typical Nickel Metal Hydride No. 5 battery management system is mainly divided into two parts: the master control module and the slave control module. Specifically, it is composed of a central processing unit (main control module), a data acquisition module, a data detection module, a display unit module, and control components (fuse devices, relays). Generally, data information communication between modules is achieved by using internal CAN bus technology. Based on the functions of each module, BMS can detect the voltage, current, temperature and other parameters of the power Nickel Metal Hydride No. 5 battery in real time, realize thermal management, balance management, high voltage and insulation detection of the power battery, and can calculate the remaining capacity, charge and discharge power and SOC&SOH status of the power battery. Why does Nickel Metal Hydride No. 5 battery need a BMS management system? Lithium batteries have poor safety and sometimes explode. In particular, lithium batteries with lithium cobalt oxide as the positive electrode material cannot be discharged at a large current and have poor safety. In addition, overcharging or over-discharging of almost all types of lithium batteries will cause irreversible damage to the battery cell. Lithium batteries are also extremely sensitive to temperature: if used at too high a temperature, it may cause electrolyte decomposition, combustion or even explosion; too low a temperature will cause the performance of the Nickel Metal Hydride No. 5 battery to deteriorate significantly, affecting the normal use of the equipment. Due to the limitations of the Nickel Metal Hydride No. 5 battery manufacturing process, the internal resistance and capacity of each battery cell will vary. When multiple battery cells are used in series, the charging and discharging rates of each battery cell will be inconsistent, which leads to low utilization of battery capacity. In view of this, lithium batteries usually require a special protection system to monitor the health status of the battery in actual use, so as to manage the use process of lithium batteries. The Nickel Metal Hydride No. 5 battery management system can effectively monitor, protect, balance energy and alarm faults of Nickel Metal Hydride No. 5 battery packs, thereby improving the working efficiency and service life of the entire power battery pack. Lithium batteries are widely used in various precision equipment due to their many advantages such as high working voltage, small size, light weight, high energy density, no memory effect, no pollution, low self-discharge, and long cycle life. Although lithium batteries have more advantages than other types of batteries, there is a risk of explosion when lithium batteries are in a severely overcharged state, which not only damages the Nickel Metal Hydride No. 5 battery pack but also threatens the life safety of users. Therefore, it is necessary to equip the Nickel Metal Hydride No. 5 battery pack with a targeted Nickel Metal Hydride No. 5 battery management system BMS to effectively monitor, protect, balance energy and alarm faults of the battery pack, thereby improving the working efficiency and service life of the entire Nickel Metal Hydride No. 5 battery. The Nickel Metal Hydride No. 5 battery BMS management system has the following features: ● The Nickel Metal Hydride No. 5 battery management system consists of a management host (CPU), a voltage and temperature acquisition module, a current acquisition module, and a communication interface module. ● It can detect and display the total voltage, total current, and reserve power of the Nickel Metal Hydride No. 5 battery pack; the voltage of any single battery and the temperature of the battery box; the highest and lowest single battery voltage and battery number, the highest and lowest temperature, and the charge and discharge capacity of the battery pack. ● The UPS battery host also provides an alarm and control output interface to alarm and control output for extreme conditions such as overvoltage, undervoltage, high temperature, low temperature, overcurrent, and short circuit. ● Provide RS232 and CAN bus interfaces, and all information on the Nickel Metal Hydride No. 5 battery management system can be directly read on the computer. The main purpose of the Nickel Metal Hydride No. 5 battery management system is to ensure the design performance of the battery system, and provide functions from three aspects: safety, durability, and power. In terms of safety, the BMS management system can protect the battery cells or battery packs from damage and prevent safety accidents. In terms of durability, even if the Nickel Metal Hydride No. 5 battery works in a reliable safety area, the battery life is extended. In terms of power, the working state of the Nickel Metal Hydride No. 5 battery must be maintained under the condition of meeting the vehicle requirements. A good Nickel Metal Hydride No. 5 battery management system has a temperature sensor that can monitor the voltage of a single battery pack and detect low-performance batteries before the battery pack is packaged. An excellent BMS can also detect the humidity of the Nickel Metal Hydride No. 5 battery pack to avoid accidents.
