我们自己设计的16节主动均衡板,完全参考TIDA-00817,但是实际测试中发现,均衡电流不对,而且电流出现时间很短,且幅值超出预期,并且没有收到任何报警。关于EMB1499和1428的说明书有没有更详细的原理介绍或者实际逻辑工作图?下图紫色为单节电池侧的电流,蓝色为电池包侧均衡电流。第二幅图中,紫色为单节电池电流,黄色是DO...
1. EMB1428Q和EMB1499Q主动均衡电路是否有什么信号对干扰特别敏感,是否可能是板子地过孔的差异,导致的电磁环境不同造成的。 2. EMB1428Q的SDO口输出的错误代码0001是指的什么错误。
EMB1499Q双向电流DC /DC控制器IC与EMB1428开关矩阵栅极驱动器IC配合使用,支持TI基于开关矩阵的有源电池平衡方案电池管理系统。 EMB1499Q为双向正激转换器提供三个PWM MOSFET栅极信号,使其输出电流(正或负)可在用户定义的幅度范围内调节。该电感电流由EMB1428通过开关矩阵引导至需要充电或放电的电池。在典型方案中,基于...

is regulated around a user-defined magnitude. This inductor current is channeled by the EMB1428 through the switch matrix to the cell that needs to be charged or discharged. In a typical scheme, the EMB1499Q-based forward converter exchanges energy between a single cell and the battery stack ...
在使用中,1499由1428使能,检测到的故障情况通过DONE和Fault引脚传递给1428。下图是我们抄了很久的结构图。在这个方案中,基于EMB1499Q的正激转换器在单个电池与其所属的电池组之间交换能量,最大堆电压高达60V,开关频率固定为250kHz。 在某些人看来,1499起到的控制DONE和Fault管脚的作用可以忽略不计,而电池电压、电流...
请问1)在EMB1428手册中Table 3/P22 中fault[3:0]=1010时,FAULT_INT triggered为什么是YES? 2)用EM1402的评估板,自己焊接EMB1428和EMB1499主动均衡部分,CPU发出去的是0x10,EMB1428返回的为0xA1,感觉通信部分应该没错
