The invention discloses a safety charging box for a battery of an electric bicycle battery, belonging to the technical field of automatic control. The safety charging box involves sensor detection, 220-V alternating current control and 5-V direct current electronic circuit control. The charging box is specially used for charging the electric bicycle; the box is a semi-sealed metal box body, and ahigh-temperature and smoke sensor is arranged in the box body; and when high temperature or smoke occurs in the box body during charging, the charging box automatically cuts off a charging power supply, a smoke alarm indicator lamp or a high-temperature alarm indicator lamp is lightened, and buzzing is conducted at the same time, so a user is reminded to take measures immediately. The box is characterized in that a relay for disconnecting the charging power supply adopts the mode of dropping out under the condition of voltage loss; and when the relay works abnormally, the charging power supplydoes not work, so it can be guaranteed that when equipment breaks down, the rechargeable battery cannot be charged. Meanwhile, the rechargeable battery is placed in a metal box, and a charger is placed outside the box, so equipment can be protected as much as possible.

    本专利申请的名称为“电动自行车电池安全充电箱”其技术领域属于自动控制领域。包括传感器检测,220伏交流电控制和5伏直流电电子电路控制。此款充电箱专为电动自行车充电使用,此箱为一半密封金属箱体,内有高温和烟雾传感器,当充电时遇到箱体内高温,或出现烟雾时,充电箱自动切断充电电源。同时点亮烟雾报警指示灯或高温报警指示灯,并伴有蜂鸣声,以提醒用户立即采取措施。此箱的特点是:断开充电电源的继电器采用“失压脱扣”形式,当继电器工作不正常时,充电电源不工作,可以保证当设备出现故障时,不会为充电电池充电。同时充电电池放于金属箱内而充电器放于箱外,能尽可能保护设备。
