Test apparatus for checking a battery control device or a battery, and method for testing a battery control device or a battery

The invention relates to a test apparatus for checking a battery control device or for checking a battery having at least one cell, comprising a battery simulator (18) for simulating a voltage of at least one cell of a simulated battery for specification on the battery control device, wherein the battery control device or the battery is connected to an evaluation module (14) via a rail designed as a central bus in order to process and check the voltage of a selected cell, wherein the selected cell of the battery simulator for the battery control device or the selected cell of the battery can be selected via a separation module (24). In this way, a test apparatus for checking a battery control device or for checking a battery can be provided, which has a simple construction and can check all of the cells of a simulated or actual battery in a simple manner. 本发明涉及种用于检查电池组控制设备或者用于检查具有至少个电池的电池组的测试装置，包括电池组模拟器（18），用于模拟所模拟的电池组的至少个电池的电压以用于预先给定给电池组控制设备，其中电池组控制设备或电池组通过被实施为中央总线的汇流排与分析模块（14）连接以用于处理和检查所选择的电池的电压，其中用于电池组控制设备
