The requirements and design of 14250 battery PCM can be divided into: basic protection, communication, BMS basic protection: basic protection includes overcharge, power loss, overcurrent and overcurrent protection, communication such as over-temperature protection can be improved according to product requirements; communication protocol can Divided into I2C, RS48RS23CANBUS, HDQ, system bus, etc. In addition, there is a simple power display that displays information through LEDs with charging heads. BMS: BMS is the acronym for Rechargeable Battery Intelligent Management System, which is called the battery management system and is commonly known as the battery nanny or battery steward. It is mainly used to intelligently manage and maintain each battery module, avoid overcharging and overcharging of the battery, extend the service life of the battery and monitor the status of the battery. Its main functions include: real-time monitoring of battery physical parameters; battery status estimation; online diagnosis and warning information; battery charging, charge-discharge and pre-charge control; balance management and thermal management, etc. The secondary system is mainly used for batteries of pure electric vehicles.
Many manufacturers are experimenting with pure electric vehicles. The main ways to increase the specific energy are to increase the working standard voltage of each 14250 battery and to increase the nickel content in the ternary material. However, the current manufacturing industry is still in the stage of development and there are no large-scale products. This is mainly because at present, the high safety, consistency, low cost and long life of power lithium batteries must be considered first, and increasing capacity is not the main problem. The main problem of ternary materials is that as the nickel content increases, the pH of the material becomes stronger, and the requirements for battery production technology and the environment are getting higher and higher; at the same time, the heat resistance of the material decreases, which will occur during the circulation process. The release of CO2 causes the structural stability of the material to deteriorate; in the case of concentration polarization, nickel has strong reducing properties, which requires the electrolyte solution to have higher matching properties. Therefore, ternary metal electrodes have high limitations in marketing and application.
As a medium for lithium-ion battery implantation, the negative electrode material should meet the following requirements: the oxidation-reduction potential difference of the lithium-ion battery in the negative electrode routine should be as low as possible, close to the potential difference of metallic lithium, so that the input voltage of the battery is high ; A large amount of lithium in the conventional can be reversibly inserted and slipped out to obtain high capacitance; during the insertion/slip-out process, the main structure of the negative stage does not change or changes little; the redox potential difference should be accompanied by the increase of lithium. Adding and removing changes as little as possible so that the working voltage of the rechargeable battery will not change significantly and keep the battery charged for a long time;
