摘要： An object of the present invention is to provide the device for protecting a secondary battery safely from overvoltage and overheating caused by the overcharge by using simple safety device, which provides a contacted safety device which connects between a constant voltage element showing a discharge characteristic in the state of overvoltage and a MIT (metal insulator transition) element showing a discharge characteristic in the state of overheating. Each of the constant voltage element and the MIT element are connected in parallel between a cathode lead and an anode lead of the secondary battery. The contacted safety device has a characteristic combining a discharge/heat dissipation characteristic of the constant voltage element and a discharge characteristic of the MIT element which immediately responds to the heat dissipation of the constant voltage element, resulting in effect of preventing overcharge advantageously since the contacted safety device makes discharge in terms of 2 factors of voltage and temperature in case of overcharge.

摘要： Disclosed is a secondary battery having a constant-voltage device for preventing the secondary battery from being excessively overcharged. The breakdown voltage of the constant-voltage device is lower than the explosion or ignition voltage of the secondary battery, so the discharge operation may occur before the secondary battery is exploded or ignited even if the voltage of the secondary battery rises above the overcharge voltage, thereby protecting the secondary battery from explosion or ignition. The leakage current value of the constant-voltage device is less than 0.05% of the capacity value of the secondary battery under the maximum charge voltage of the secondary battery, or the breakdown voltage of the constant-voltage device is higher than the maximum charge voltage of the secondary battery. Thus, the constant-voltage device rarely generates the leakage current even if the secondary battery has been charged with the maximum charge voltage.
摘要翻译：公开了具有用于防止二次电池过度充电的恒压装置的二次电池。恒压装置的击穿电压低于二次电池的爆炸或点火电压，因此即使二次电池的电压升高到过充电电压以上，放电操作也可能在二次电池分解或点燃之前发生，从而保护二次电池免受爆炸或点火。在二次电池的最大充电电压下，恒压装置的漏电电流值小于二次电池容量值的0.05％，或恒压装置的击穿电压高于最大充电电压的二次电池。因此，即使二次电池被充电最大充电电压，恒压装置也很少产生漏电流。
