Design and implementation of a battery formation and grading control system based on bit vector search algorithm

可二次充电的锂离子电池由于其污染小、能量密度高、成本低等特点，逐渐取代传统储能设备。电池化成分容系统用于对锂电池进行化成与测试。传统的系统由于设备的性能限制，在扩大通道规模的同时无法实现通道的单点控制，满足不了对电池的各种化成与测试的需求。 通过分析传统系统结构体系，本项目设计了一套新型的电池化成分容系统。该系统通过设计一个上位机直接控制下位机的化成分容通道的方式，简化了中位机的功能，在进一步扩大通道规模的同时从上位机软件上实现了单点控制的功能。 上位机控制大量的通道，但是每个通道在某个时间段内需要控制的概率低。根据这个特点，本文提出一种位向量搜索算法，该算法将多个通道映射为一个整型变量....The rechargeable lithium-ion batteries is being taking the place of the traditional energy storage device because of its less pollution, high energy density and low cost.The battery formation & grading system is used to battery formation and testing.

Determination of the number of ψ(3686) events taken at BESIII

The number of ψ(3686) events collected by the BESIII detector during the 2021 run period is determined to be (2259.3±11.1)×106 by counting inclusive ψ(3686) hadronic events. The uncertainty is systematic and the statistical uncertainty is negligible. Meanwhile, the numbers of ψ(3686) events collected during the 2009 and 2012 run periods are updated to be (107.7±0.6)×106 and (345.4±2.6)×106, respectively. Both numbers are consistent with the previous measurements within one standard deviation. The total number of ψ(3686) events in the three data samples is (2712.4±14.3)×10^
