9v alkaline battery

　　Is the BMS 9v alkaline battery pack management system also called 9v alkaline battery protection board?

　　Is the BMS 9v alkaline battery pack management system also called 9v alkaline battery protection board? The battery is the component with the most frequent problems in electric vehicles and is a key factor hindering the promotion and industrialization of electric vehicles. If there is a problem with a single cell in the battery pack, the entire electric vehicle will not be able to work properly. BMS 9v alkaline battery pack management system And the 9v alkaline battery protection board is to protect the 9v alkaline battery, so is there any difference between them? Is the BMS 9v alkaline battery pack management system also called 9v alkaline battery protection board?

　　BMS 9v alkaline battery pack management system

　　The battery management system (BMS) is the link between the battery and the user, and its main target is the secondary battery. Secondary batteries have the following shortcomings, such as low storage energy, short life, problems in series and parallel use, safety of use, and difficulty in estimating battery power, etc. The performance of batteries is very complex, and the characteristics of different types of batteries vary greatly. The main purpose of the battery management system (BMS) is to improve battery utilization, prevent battery overcharge and overdischarge, extend battery life, and monitor battery status. As the battery management system develops, other functions will be added.

　　BMS hardware topology

　　The topology structure of BMS hardware is divided into two types: centralized and distributed. The centralized type integrates all functions of the battery management system into one controller. It is more suitable for situations where the 9v alkaline battery pack capacity is relatively small and the module and battery pack types are relatively fixed. It can significantly reduce system costs. Distribution is to separate the main control board and slave control board of the BMS, and even separate the low-voltage and high-voltage parts to increase the flexibility of system configuration and adapt to modules and battery packs of different capacities and specifications.

　　BMS 9v alkaline battery pack management system functions

　　Battery management systems are a critical component of electric and hybrid vehicles. In order to ensure the safe and reliable operation of the battery, the battery management system needs to have the following three functions:

　　1. Accurately estimate the state of charge of the power battery pack

　　2. Dynamically monitor the working status of the power battery pack

　　3. Balance between single cells

　　9v alkaline battery protection board

　　9v alkaline battery protection boards usually include control IC, MOS switches, resistors, capacitors and auxiliary devices NTC, ID memory, etc. It is a charge and discharge protection for series-connected 9v alkaline battery packs; when fully charged, it can ensure that the voltage difference between each single cell is less than the set value (generally ±20mV), achieving even charging of each single cell in the battery pack, effectively improving It improves the charging effect in series charging mode; simultaneously detects the overvoltage, undervoltage, overcurrent, short circuit, and overtemperature status of each single cell in the battery pack to protect and extend the service life of the battery; undervoltage protection ensures that each single battery Avoid battery damage due to over-discharge during discharge use.

　　Among them, the control IC controls the MOS switch to turn on under normal circumstances, allowing the cell to communicate with the external circuit. When the cell voltage or loop current exceeds the specified value, it immediately (tens of milliseconds) controls the MOS switch to turn off. Protect the safety of battery cells.

　　The main function of 9v alkaline battery protection board

　　It is generally required that the Control (IC) detects and controls the cell voltage and the current and voltage of the charge and discharge circuit at -25°C ~ 85°C. Under normal circumstances, the C-MOS switch is turned on to protect the cell and 9v alkaline battery circuit. The board is in normal working condition, and when the cell voltage or the operating current in the circuit exceeds the preset value of the comparison circuit in the control IC, within 15 to 30ms (different control ICs and C-MOS have different response times), the CMOS Shutdown means closing the cell discharge or charging circuit to ensure the safety of the user and the cell.

　　As a powerful guarantee for the safe use of batteries, the 9v alkaline battery BMS management system enables the battery to be in a safe and controllable charging and discharging process at all times, greatly improving the cycle life of the battery in actual use. The 9v alkaline battery management system can ensure the safety of the power 9v alkaline battery pack, which is the primary task of the lithium power battery management system. Do you know it now?
