  • 电池管理系统的多点温度测量方案

      Abstract: It is critically important that lithium-ion battery stacks have a good battery-management system for monitoring many cellvoltages and cell temperatures. Without that monitoring, thermal runaway can lead to a battery explosion. This design idea presentsa low-power circuit that me ...

  • 如何运用DC-DC升压调节器

      便携式电子器件(如智能手机、GPS导航系统和平板电脑)的电源可以来自低压太阳能电池板、电池或AC/DC电源。电池供电系统通常将电池串联叠置以实现更高的电压,但由于空间不足,此技术未必总是可行。开关转换器使用电感的磁场来交替地存储电能,并以不同电压释放至负载。因为损耗很低,所以开关转换器是个不错的高 ...

  • 变压器局部发热故障分析

    热故障通常为变压器内部局部过热、温度升高。根据其严重程度,热性故障常被分为轻度过热(一般低于150℃)、低温过热(150—300℃)、中温过热(300~700℃)、高温过热(一般高于700℃)四种故障隋况。电故障通常指变压器内部在高电场强度的作用下,造成绝缘性能下降或劣化的故障。   ...
