摘要
本文提出了一种新的电池内阻监测方法,给出了由MSP430LF135单片机组成的低功耗系统的具体硬件设计原理和软件设计流程。测试结果表明,运用锁相环电路和基准电阻补偿技术后,系统的精度大大提高,满足了一般用户的要求,具有广阔的发展空间。
This paper brings forward a new monitoring method to internal resistance of cell; at the same time, it gives a specific hardware schematics and software flow chart of the low- power system which is composed of msp4301f135（MCU）.After utilizing the phase locked loop and the benchmark resistance compensating technology, the result of test shows that the accuracy of the system is improved evidently, it can satisfy the general user＇s requirement and has a broad space for development.
