Abstract: An electrochemical cell comprises a negative electrode, an positive electrode, a cell case, and a solid electrolyte. The cell case comprises an outer case and an inner case. The solid electrolyte defines a first chamber to receive the negative electrode and is disposed within the inner case to define a second chamber. The second chamber is separated from and is in ionic communication with the first chamber to receive the positive electrode. The electrochemical cell further comprises a first current collector extending into the first chamber. Wherein an open upper end of the inner case extends beyond an open upper end of the outer case. A cell case and a method for making an electrochemical cell are also presented.

Abstract: A battery system has a battery module including a number M of series-connected batteries. The battery system is further provided with a number N (1

Abstract translation: 电池系统具有包括M个串联电池的电池模块。 电池系统还设置有数个N（1≤N≤M）的电荷均衡器，每个电荷均一次连接到电池，使得电池被充电和/或放电以实现电荷均衡。 控制装置被配置为基于电池的充电状态（SOC）来确定每个电池是否需要充电均衡，比较需要电荷均衡的电池数量L和数量M，并且基于比较结果 导致关闭电池系统，或者要求电荷均衡的一个或多个电池连接到相应的电荷均衡器。 选择开关模块用于将需要电荷均衡的一个或多个电池分别连接到相应的电荷均衡器。
