一种充电桩及其掉电存储电路
摘要：
本实用新型涉及一种充电桩及其掉电存储电路，其MCU连接电源检测模块，MCU的电源端连接有稳压模块(LDO)，该稳压模块的输入端连接有一个储能电容(C1)，所述储能电容两端并联有一个泄放电路，该泄放电路中设有电子开关，所述MCU控制连接该电子开关；在储能电容C1的两端并联泄放电路，当掉电存储完成之后，泄放电路启动，把C1中的电迅速泄放为零；在保证掉电存储时间要求的同时，又能保证后备电源快速泄放，保证MCU快速进入安全状态。
摘要（英）：

The utility model relates to a stake of charging and fall electric memory circuit thereof, its MCU connect the power detecting module, and MCU's power end is connected with voltage stabilizing module (LDO), and this voltage stabilizing module's input is connected with an energy -storage capacitor (C1), the energy -storage capacitor both ends are parallelly connected to have a bleeder circuit, is equipped with electronic switch in this bleeder circuit, this electronic switch of MCU control connection, at the parallelly connected bleeder circuit in energy -storage capacitor C1's both ends, after falling electricity storage completion, the bleeder circuit starts, releases the electricity among the C1 rapidly into zero, when guaranteeing electric storage time requirement, can guarantee the back -up source again and release fast, guarantee that MCU gets into safe state fast.
