The invention discloses an electric bicycle battery overdischarge detection device, and effectively solves the problem that an over-discharge phenomenon is caused or the electric quantity cannot be fully utilized due to setting of a fixed termination voltage in the prior art. A voltage sensor U1 and a current sensor U2 are used for detecting a terminal voltage signal of a single battery and a discharge current signal of the battery, the terminal voltage signal is compared with a preset terminal voltage value on a window comparator, and when a first OR gate circuit is switched on, it is indicated that the battery is about to generate an over-discharge phenomenon, and a signal output circuit amplifies an alarm signal output by the discharge current detection circuit and outputs the alarm signal to a display screen to remind people that the battery is about to be over-discharged, so that the influence on the travel of people is reduced, and the termination voltage is set to be within a range. The problem that a fixed termination voltage is set to cause an over-discharge phenomenon or the electric quantity cannot be fully utilized is avoided.
本发明公开了一种电动自行车电池过放电检测装置,有效的解决了现有技术设置固定终止电压而引起过放电现象或电量不能得到充分利用的问题,本发明的电压传感器U1和电流传感器U2来检测单体电池的端电压信号和电池的放电电流信号,端电压信号在窗口比较器上与预设的端电压值进行比较,当第一或门电路导通时则表明电池即将发生过放电现象,利用信号输出电路将放电电流检测电路输出的警报信号进行放大后输出至显示屏,来提醒人们电池即将发生过放电现象,减少了对人们行程的影响,将终止电压设置为一个范围,避免设置固定终止电压而引起过放电现象或电量不能得到充分利用的问题发生。
