The invention discloses a monitoring device and a protection circuit for a plug connector, relates to the technical field of battery monitoring, and solves the technical problem that a power plug connector of a storage battery pack of an electric vehicle is easy to be on fire due to lack of monitoring, and the key point of the technical scheme is that a monitoring device is additionally arranged on the plug connector of the storage battery pack, a vehicle load, a charger and the like; when the plug connector is used for plugging, heating caused by non-tight plugging, loosening and the like is prevented, and heating, fire and the like caused by oxidation and abrasion of contact points are also prevented at the same time. According to the scheme, the cost is low, whether the male connector and the female connector are inserted in place and tightly or not is monitored, protection is carried out by monitoring the temperature, and the safety problems of fire and the like caused by the connectors can be reliably protected; at present, the socket on the electric two-wheeled vehicle is not provided with any monitoring device, and the application fills up the deficiency and blank in the field.
本发明公开了一种用于插接件的监测装置、保护电路,涉及电池监测技术领域,解决了电动车蓄电池组功率接插件由于缺乏监测而易起火的技术问题,其技术方案要点是在蓄电池组与车辆负载、充电器等的接插件上增加一个监测装置,当插接件进行插接时,防止由于未插紧、松脱等造成的发热,同时也防止了由于接触点氧化、磨损造成的发热起火等。该方案成本较低,不仅监测了公、母接插件是否插到位及插紧,同时也通过监测温度进行保护,实现后能可靠的对由于接插件造成的起火等安全问题起到可靠的保护;且目前电动两轮车上接插口不带任何监测装置,本申请填补了该领域的缺失与空白。
