China battery manufacturers use lithium batteries in groups, each section of lithium batteries are required to charge overvoltage, discharge under voltage, overcurrent, short circuit protection, charging process to achieve the whole group of balanced battery charging problem, lithium battery manufacturers introduced a The use of a single lithium battery protection chip on any number of serial number of lithium batteries to protect the balance with the charging function of the battery protection board design. Lithium battery manufacturers simulation results and industrial production applications prove that the protection board protection function is perfect, stable, cost-effective, balanced charging error of less than 50mV. Lithium battery manufacturers commonly used balanced charging technology, including constant shunt resistance equalization charge, on-off shunt resistance balanced charge, the average battery voltage balanced charge, switching capacitor balanced charge, buck converter balanced charge, inductive balanced charge. Lithium battery manufacturers in groups of lithium batteries in series charge, should ensure that each battery balance charge, otherwise the use of the process will affect the performance of the entire battery and life. And the existing lithium battery manufacturers single-cell lithium battery protection chip does not contain balanced charge control function, lithium battery manufacturers multi-section lithium battery protection chip balanced charge control function requires an external CPU; and through the protection of the chip serial communication (such as I2C bus ) To achieve, increased the complexity of the protection circuit and design difficulties, reducing the efficiency and reliability of the system, increasing power consumption. Shenzhen Lithium Energy Technology Co., Ltd. lithium battery manufacturers in 2013-01-02 incorporated in Shenzhen City, lithium battery manufacturers Main Tablet PC batteries, variety, fair prices, and with a number of retailers and agents to establish a long-term Stable cooperative relationship. Enterprise strength, re-credit, keep the contract to ensure product quality, lithium battery manufacturers to more varieties of operating characteristics and the principle of small profits, won the majority of the needs of the community's trust.
