The invention relates to an apparatus and a method for coordinating a contactor-fuse system. A protection system for a battery system includes a battery control module configured to selectively open at least one contactor to isolate the battery system from a load in response to a sensed current being greater than a first threshold and within a first current range; at least one fuse connected between the first terminal and the second terminal of the battery system and configured to open to isolate the battery system from the load in response to the sensed current being greater than a second threshold and within a second current range, the second current range is larger than the first current range and deviates from the first current range; and an auxiliary protection module configured to selectively form a short circuit between the first terminal and the second terminal in response to the sense current being greater than the first threshold, less than the second threshold, and within the coverage discontinuity between the first current range and the second current range.

    本发明涉及用于协调接触器‑熔断器系统的设备和方法。用于电池系统的保护系统包括电池控制模块,该电池控制模块配置为响应于感测电流大于第一阈值并且在第一电流范围内来选择性地断开至少一个接触器以使电池系统与负载隔离;至少一个熔断器,该至少一个熔断器连接在电池系统的第一端子和第二端子之间并且配置为响应于感测电流大于第二阈值并且在第二电流范围内来断开以使电池系统与负载隔离,该第二电流范围大于第一电流范围并且偏离第一电流范围;和辅助保护模块,该辅助保护模块配置为响应于感测电流大于第一阈值、小于第二阈值并且在第一电流范围和第二电流范围之间的覆盖间断区域内来选择性地在第一端子和第二端子之间形成短路。
