本发明应用于对分布式移动储能系统进行控制，以防止分布式移动储能系统的电源连接线掉落导致打火等情况。
实施例一
请参照图1，本实施例的一种改进基包1与电池包2连接控制的移动储能电源系统包括基包1、电池包2和电源连接线3，其中，基包1包括基包插座11，电池包2包括电池包插座21，电源连接线3通过基包插座11和电池包插座21电连接基包1和电池包2。
请参照图1和图2，电源连接线3与基包插座11和电池包插座21电连接形成主回路、辅助供电回路、485通讯回路和IO回路，其中，主回路的接口包括B+接口和B-接口，用于基包1从电池包2取电并对外供应220V交流电压，辅助供电回路的接口包括P+接口和P-接口，用于基包1的控制模块从电池包2中取电，485通讯回路的接口包括1号接口和2号接口，用于基包1下发控制指令给到电池包2，IO回路的接口包括V+接口和GND接口，用于提供连接信号，基包1通过IO回路判断与电池包2是否处于连接状态。
具体而言，V+接口和GND接口分别与基包1的控制模块的5V电源的正负极电连接，且V+接口，GND接口与控制模块的IO口的正负极电连接。当电源连接线3的另一端与电池包2的插座21连接时， V+接口和GND接口的对应的两个接口2A、2B短接。因此，当电源连接线3连接基包1与电池包2的时候，V+接口和GND接口之间形成从V+→2A→2B→GND的IO回路，基包1检测IO口处于高电平状态，其表示电源连接线3与两端的插座连接正常，而电源连接线3未连接基包1与电池包2的时候，当基包1检测IO口处于低电平状态，说明此时电源连接线3与两端的插座连接松脱。
电源连接线3内部，在IO回路中的V+接口导线上设置有一个自锁型微动开关31，电源连接线3外部设置有一个瞬动型按钮32，请参照图1和图3，瞬动型按钮32和自锁型微动开关31通过辅助操作杆33机械连接，从而实现机械互锁，当用户使用外力按下瞬动型按钮32，辅助操作杆33跟随着动作，顶到微动开关31，微动开关31从常闭状态变为常开状态，V+接口到GND接口形成的回路断开，此时基包1可以检测到IO口处于低电平状态。
进一步的，电源连接线3的两端具设有卡扣钩锁装置，卡扣钩锁与按钮32连接，仅在按钮32按下的情况下，卡扣钩锁松动，此时电源连接线3方可与基包1和/或电池包2相插拔，当按钮32弹起的情况下，卡扣钩锁恢复状态，紧密勾住基包1和电池包2的插座，保证电源连接线3和插座的连接紧密，放置松脱掉落导致使用危险。
需要拔出电源连接线3时，先按下按钮32，此时IO回路处于低电平状态，并且卡扣钩锁松动，电源连接线3便可顺利拔出。
需要说明的是，检测到IO回路处于高电平表示电源线3与基包1以及电池包2连接正常；检测到IO回路处于低电平表示电源线3与基包1或者电池包2未正常连接，或者是按钮32被按下。
基包1的控制模块在工作中：
初始时，当基包1检测到IO口处于高电平时，表明此时电源连接线3两端已与基包1和电池包2的插座进行了连接，并且按钮32已经松开，由于卡扣钩锁的存在，其不易松脱，说明基包1已经通过电源连接线3与电池包2建立稳定的电连接关系，因此，基包1的控制模块认为基包1与电池包2处于紧密连接的状态，则基包1的控制模块下发指令给电池包2，使电池包2和基包1正常输出。
在移动储能电源系统正常充放电时，若要拔出电源连接线3，由于卡扣钩锁的存在，需要先按下按钮32，按钮32带动微动开关31断开，此时IO回路截止，基包1的控制模块认为连接异常，则控制模块通过485通信接口给电池包2下发指令，使得电池包2与基包1停止输出，实际测试中，本实施例的电池包2与基包1能在100ms的时间内停止输出，由于停止输出的时间足够快，因此能保证电源连接线3断开的时候，整个设备均处于停止输出的断电状态，电源连接线3可以顺利安全脱出，避免了电源连接线3带电拔插对设备产生冲击和电弧的产生，且此时插座也将不会带电，避免了使用人员触电的风险。
在移动储能电源系统正常充放电时，若发生移动储能电源系统跌落、碰撞等情况导致的电源连接线3与基包1或电池包2连接断开的情况下，IO回路也会发生截止，基包1的控制模块同样也能得到连接异常的反馈，及时切断电池包2与基包1的输出，避免危险的发生。
基包1的控制模块间隔预设周期对IO回路进行检测，例如判断周期为20ms，可以保证在出现电池包与基包连接状态异常时，基包输出控制模块及时响应，及时动作，保障了用户使用安全。
综上所述，本发明提供的一种改进基包与电池包连接控制的移动储能电源系统，其通过基包检测IO回路，从而检测基包是否通过电源连接线与电池包建立了连接，当基包的控制模块认为连接异常，则下方命令停止电池包放电，使得电池包与基包停止输出，因此能保证电源连接线断开的时候，整个设备均处于停止输出的断电状态，电源连接线可以顺利安全脱出，避免了电源连接线带电拔插对设备产生冲击和电弧的产生，且此时插座也将不会带电，避免了使用人员触电的风险，IO回路上串联微动开关，通过按钮带动，从而能在电源连接线插牢的情况下才闭合IO回路，避免未插牢的情况下基包便检测到电源连接线已连接，造成安全隐患，可拆卸固定连接件用于与基包和电池包建立可拆卸固定连接。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等同变换，或直接或间接运用在相关的技术领域，均同理包括在本发明的专利保护范围内。
