  • 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 ...
