在一种实施方式中，供电状态包括供电持续时间；其中，基于电源模块向外部负载设备的供电状态，断开电源端101和负载端102之间的电连接或者限流，包括：基于供电持续时间，断开电源端101和负载端102之间的电连接或者限流。如此，第一保护模块103基于供电持续时间可以断开电源端101和负载端102之间的连接，有利于解决供电时间过长导致的温度过高的问题。
示例性地，第一保护模块103的温度与供电状态相关，第一保护模块103基于第一保护模块103的温度监控输出供电的供电状态，基于第一保护模块103的温度，断开电源端101和负载端102之间的电连接或者限制电流。对于不同供电状态，第一保护模块103的温度会呈现不同温度，例如供电电流超过预设电流阈值后，随着供电电流增大，第一保护 模块103的温度上升，则可以通过温度升高来判断供电电流增大。因此，第一保护模块103直接基于自身温度的异常，断开电源端101和负载端102的电连接或者进行限流，从而实现基于供电状态断开电源端101和负载端102的电连接或者限流。
示例性地，基于第一保护模块103的温度，断开电源端101和负载端102之间的连接，包括：响应于第一保护模块103的温度不符合预设温度范围，断开电源端101和负载端102之间的连接。示例性地，预设温度范围可以包括小于预设温度阈值。第一保护模块103的温度达到预设温度阈值时，第一保护模块103触发断开电源端101和负载端102之间的连接。
在一种实施方式中，基于输出供电的供电状态，断开电源端101和负载端102之间的连接，包括：响应于供电电流的数值大于预设电流阈值，且供电电流的供电持续时间不小于响应时间，断开电源端101和负载端102之间的连接；其中，响应时间与供电电流的数值呈负相关。如此，对于异常的供电电流，其电流数值越大，其对应的响应时间越小，越快断开电路连接或者限制电流，能够更加有效保护电路安全。
在一种实施方式中，第一保护模块103还用于响应于供电电流的数值不大于预设电流阈值，第一保护模块103保持导通电源端101和负载端102之间的正常电连接，实现正常通电。
在一种实施方式中，在负载端102反接外部负载设备的情况下，电源模块向外部负载设备供电的电流值大于预设电流阈值。如此，通过提前设定第一保护模块103的预设电流阈值，使得外部负载设备反接时，输出供电的电流值大于预设电流阈值，当该电流输出的时间达到相应的响应时间，则断开电路连接或限制电流，保障电路安全。
示例性地，外部负载设备反接包括：负载正端连接外部负载设备的负极，负载负端连接外部负载设备的正极，从而，电源模块的正极通过电源正端BAT+连接外部负载设备的负极，电源模块的负极通过电源正端BAT+连接外部负载设备的正极。在外部负载设备反接的情况下，电源模块向外部负载放电时电流过大，电路存在安全问题。
在一种实施方式中，在负载端102短路的情况下，电源模块向外部负载设备供电的电流值大于预设电流阈值。如此，负载端102短路时，输出供电的电流值大于预设电流阈值，当该电流输出的时间达到相应的响应时间，则断开电路连接或限制电流，保障电路安全。

在一种实施方式中，第一保护模块103还用于在断开电源端101和负载端102之间的连接后，如果第一保护模块103的状态达到预设恢复条件，恢复电源端101和负载端102之间的正常通电状态如此，第一保护模块103提供恢复功能，使得输出控制电路可以恢复正常输出，且第一保护模块103可以继续为输出控制电流提供过流保护。此外，第一保护模块103基于自身状态可以自动恢复电源端101和负载端102之间的正常通电状态，无需通过其它硬件识别电路或者软件识别电路的控制，实现自身控制作用。
在一种实施方式中，预设恢复条件包括第一保护模块103的温度小于预设温度阈值。如此，第一保护模块103的温度下降至预设温度阈值以下，第一保护模块103可以重新连接电源端101和负载端102之间的连接。
在一种实施方式中，在负载端102短路的情况下，第一保护模块103基于电源模块向外部负载设备的供电状态，断开电源端101和负载端102之间的电连接或限流。
负载端102短路切换为负载端102空载或负载端102正接外部负载设备的情况下，第一保护模块103从断开电源端101和负载端102之间的电连接或限流切换为恢复电源端101和负载端102之间的正常通电状态。
在一种实施方式中，第一保护模块103包括保险丝元件。示例性地，保险丝元件的一端连接电源端101，保险丝元件的另一端负载端102。如此，电源模块向外部负载端102输出的供电电流经过保险丝元件，使得保险丝元件监控到供电电流。
在一种实施方式中，第一保护模块103中存在至少两个保险丝元件并联连接于电源端101和负载端102之间。示例性地，参见图2示例，第一保护模块103包括四个保险丝元 件PTC，即第一保险丝元件PTC1、第二保险丝元件PTC2、第三保险丝元件PTC3和第四保险丝元件PTC4，四个保险丝元件并联连接于电源正端BAT+和负载正端CAR+之间。如此，供电电流可以分流通过各个保险丝元件，降低了对单个保险丝元件电流承载能力的要求。
在一种实施方式中，保险丝元件包括自恢复保险丝元件。其中，自恢复保险丝元件，也可以称为可恢复保险丝是一种过流电子保护元件。自恢复保险丝具有过流过热保护，自动恢复双重功能。如此，无需复杂的硬件识别电路和软件识别电路，即可对电路进行有效保护，避免因硬件识别电路或者软件识别电路失效而无法进行有效的电路保护，电路结构简单，且可靠性高。

在一种实施方式中，第二保护模块301包括单向导通元件。如此，第二保护模块301利用单向导通元件，则可以实现防止外部负载设备向电源模块充电，无需借助其它检测电路识别电流是否反向，电路结构简单利于实现。
在一种实施方式中，第二保护模块301中存在至少两个单向导通元件并联连接于电源端101和负载端102之间。示例性地，参见图4示例，第一保护模块103包括四个单向导通元件，即第一单向导通元件D1、第二单向导通元件D2、第三单向导通元件D3和第四单向导通元件D4，四个单向导通元件并联连接于电源正端BAT+和负载正端CAR+之间。如此，供电电流可以分流通过各个单向导通元件，降低了对单个单向导通元件电流承载能力的要求。
在一种实施方式中，单向导通元件包括二极管。如此，基于二极管具备单向导通特性，可以采用二极管作为单向导通元件，电路结构简单且成本低。如此，基于图4提供的电路图，利用可恢复保险丝进行过流和短路保护，利用二极管可以进行防反充电保护，将二极管的正极连接至电源模块的正极，二极管负极连接至可恢复保险丝一端，可恢复保险丝的另外一端连接至负载端102的正极。当汽车正常启动完成后，由于二极管具备电流防反向作用，汽车发电机无法给产品电池反充电，这样就有效的保护了电源模块不因汽车启动完成后产生反向充电电流。由于电路串联可恢复保险丝保护元件，当输出电流超过可恢复保险丝保护值大小时，可恢复保险丝可以限制输出电流，使电流变小，示例性地，可恢复保险丝可以使电流变小近乎为零，对用户来说相当于断开，当输出电流恢复至正常值时，可恢复保险丝自动恢复正常工作，避免因输出过流或短路产生的安全问题。
