【摘要】:为实现模拟锂电池的充放电特性,设计了一台高速高精度的电源作为锂电池模拟器来实现充放电功能。电源电路由四部分组成,主要包括电压、电流采样电路,电压、电流控制电路,推挽式结构主电路,以及驱动电路。实验证明:放电时0~5 V输出电压可调,输出电流最大为5 A,充电时实现了0~2 A的电流控制功能。电源的上升速度和下降速度响应时间均小于50μs,与普通的直流电源响应时间几十毫秒相比,该电源有着优越的响应速度。此高速电源运用于电池测试和电池充电设备测试有着很好的前景。
[Abstract]:In order to realize the charging and discharging characteristics of the simulated lithium battery, a high-speed and high-precision power supply is designed as a lithium battery simulator to realize the charging and discharging function. The power supply circuit consists of four parts, mainly comprising a voltage, a current sampling circuit, a voltage, a current control circuit, a push-pull type structure main circuit and a driving circuit. The results show that the output current is adjustable at 0 ~ 5 V at the time of discharge, the output current is 5 A, and the current control function of 0 ~ 2 A is realized at the time of charging. The response time of the rising speed and the falling speed of the power supply is less than 50 & mu; s, and the power supply has a superior response speed compared with the normal DC power supply response time of several tens of milliseconds. The high-speed power supply has a good prospect for battery testing and battery charging equipment testing.
