Abstract

一种48V电动车全自动发电装置：在电瓶供电电路中，增加了正向二极管，当发电机发电时，二极管G5输出电压高于二极管G4的输出电压，由于二极管的正向导电性，在二极管G3两端产生两个电压，用以给电瓶充电所需小电流和电动车所需的大电流。调整G1基极的上下偏流电阻R1、R2阻置的大小实现设定置44V时，自动启动发电机发电。

Description

48V电动车全自动发电装置
电路工作原理：
在48V电瓶输出电路中，为了提高自动启动发电机发电的稳定性，在G1稳压三极管基础上，又增加了G2激励三极管，用以功率放大，给继电器提供足够的电流。当电瓶正常供电时稳压三极管G1进入饱和区，该三极管不工作，当电瓶电压低于设定值时，该三极管退出饱和区，进入工作状态，此时由三极管的集电极，通过耦合电容G5把信号耦合到G2激励三极管功率放大，给继电器提供吸合电流达到自动启动发电机发电。电瓶的电量通过正向二极管G3向电动车负载电路输出正电，当电瓶的电量(电压)低于设定值44V时，发动机自动启动发电，发出的电由二极管G4向电瓶输出5A左右的直流电，二极管G5向电动车负载电路最大输出50A直流电，供48V电动车所需能量。
电路优点：
当电动车的电瓶电压低于设定值时，发动机自动启动发电，供电瓶充电所需的小电流，同时又供电动车负载所需要的大电流。
所属技术领域：
本发明适用于电动车和电瓶供电设备。
技术背景：
目前由于电动车电瓶蓄电量少，续驶里程不足，难以实现电动车于汽车接轨。
发明内容：
为克服电动车续使里程不足，当电动车电瓶电压低于设定值时，发电机自动启动发电，分别供给电瓶和电动车所需能量，确保电动车正常行驶。
在电瓶供电电路中，增加了正向二极管，当发电机发电时，二极管G5输出电压高于二极管G4的输出电压，由于二极管的正向导电性，在二极管G3两端产生两个电压，用以给电瓶充电所需小电流和电动车所需的大电流。
下面结合附图和实施对实用发明进一步说明：
说明书附图1是一种48V全自动发电型电动车原理图，按说明书附图连接，就能完成该发明。
附图1中：B1电瓶、P1续电器、P2发动机、G1稳压二极管、G2激励三极管、G4整流二极管、G3电瓶正向导电二极管、G5整流二极管、C1耦合电容、C2滤波电容、C3稳压电解电容、C4电解电容、C5耦合电容、R1上偏流电阻、R2下偏流电阻、R3发射极电阻、R4上偏流电阻、R5下偏流电阻、R6发射极电阻。调整G1基极的上下偏流电阻R1、R2阻值的大小实现设定值44V时，自动启动发电机。
具体实施方式：
调整G1基极的上下偏流电阻R1、R2阻值的大小实现设定值44V时，自动启动发电机。
