图1为根据一个或多个实施例中可逆向输出直流电压源的PV充电电路的电路图。
图2为根据一个或多个实施例中控制PV充电电路的控制器模块电路图。
具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
参考图1所示，在其中一个实施例中，提供了一种可逆向输出直流电压源的PV充电电路，包括：相连接的光伏模块10和电存储模块20；光伏模块10包括：光伏太阳能板PV及第一场效应管组件101；电存储模块20包括：第二场效应管组件201和储能器；第一场效应管组件101连接在光伏太阳能板PV的两端，光伏太阳能板PV的负极接地，第一场效应管组件101还连接控制器模块(图中未示出)；
第二场效应管组件201的两端连接储能器的两端，第二场效应管组件201连接第一场效应管组件101以及控制器模块；及
第一场效应管组件101的两端分别作为PV充电电路输出的直流电压源的正极和负极。
本实施例的PV充电电路的充电原理是：
光伏太阳能板PV吸收太阳光并转换成电能，通过控制器模块控制第一场效应管组件、及第二场效应管组件的栅极电压，使得电能经过第一场效应管组件、及第二场效应管组件存储在储能器中。
具体地，控制器模块控制第一场效应管组件101、及第二场效应管组件201的驱动电压来使电路导通，驱动电压通常为正电压、零压或者负压，比如控制器模块输出正驱动电压至第一场效应管组件101，控制器模块输出负驱动电压至第二场效应管组件201，此时可以将第一场效应管组件101看作高电平，第二场效应管组件201看作低电平，此时，由于高低电平的电势差可以使PV端的电流向储能器流动。
本实施例的PV充电电路的输出直流电压源的原理是：
控制器模块控制第一场效应管组件101、及第二场效应管组件201的驱动电压，进而控制第一场效应管组件101、及第二场效应管组件201的通断情况，比如控制器模块输出负驱动电压至第一场效应管组件101，控制器模块输出正驱动电压至第二场效应管组件201，使得存储在储能器的电能流出，最终PV充电电路输出直流电压源。且经过控制器模块进一步控制，PV充电电路可以输出不同大小的直流电压源。
其中，在一些实施例中，经过控制器模块进一步控制，PV充电电路可以输出不同大小的直流电压源的方法是：PV充电电路的负载需求为不同大小的直流电压源，由于负载不变，输出电压受电流控制，因此控制器可以通过控制第一场效应管组件101、及第二场效应管组件201的电流来控制不同大小的直流电压输出，使得PV充电电路输出不同大小的直流电压源。
本公开的PV充电电路既能通过光伏太阳能板PV进行充电，还能通过控制器模块控制场效应管组件，使得存储在储能器的电能流出，最终PV充电 电路输出直流电压源，本公开的PV充电电路简单。因而，本公开在不增加系统硬件成本的情况下，能够供更多的负载应用。
在其中一个实施例中，参考图1所示，第一场效应管组件101包括场效应管Q1及场效应管Q2；
光伏太阳能板PV的正极连接场效应管Q1的漏极，场效应管Q1的源极连接场效应管Q2的漏极，场效应管Q2的源极连接光伏太阳能板PV的负极，场效应管Q1的栅极、场效应管Q2的栅极均连接控制器模块；及
场效应管Q1的漏极、场效应管Q2的源极分别作为PV充电电路输出的直流电压源的正极和负极。
从而，基于包含场效应管Q1及场效应管Q2的第一场效应管组件101，通过控制器模块对场效应管Q1及场效应管Q2的通断进行控制，使得场效应管Q1及场效应管Q2分别呈现对应的通断状态，从而使得光伏太阳能板PV输出的电流能够通过第一场效应管组件101向电存储模块20流动。
在其中一个实施例中，场效应管Q1的栅极与控制器模块的引脚G1连接，场效应管Q2的栅极与控制器模块的引脚G2连接。具体地，控制器模块可以看作是包含升压/降压电路的芯片，升压/降压电路输出的电压信号会从引脚G1及引脚G2输出至PV充电电路的场效应管Q1及Q2，其中，引脚G1及引脚G2起输出电压的作用。
在其中一个实施例中，第二场效应管组件201包括场效应管Q3及场效应管Q4；
场效应管Q3的漏极连接储能器的正极，场效应管Q3的源极连接场效应管Q4的漏极，场效应管Q4的源极连接储能器的负极，场效应管Q3的源极和场效应管Q4的源极连接第一场效应管组件101。
从而，基于包含场效应管Q3及场效应管Q4的第一场效应管组件201，通过控制器模块对场效应管Q3及场效应管Q4的通断进行控制，使得场效应管Q3及场效应管Q4分别呈现对应的通断状态，从而使得储能器的电能流出，以输出直流电源。
在其中一个实施例中，场效应管Q3的栅极与控制器模块的引脚G3连接，场效应管Q4的栅极与控制器模块的引脚G4连接。
具体地，控制器模块可以看作是包含升压/降压电路的芯片，升压/降压电路输出的电压信号会从引脚G3及引脚G4输出至PV充电电路的场效应管Q3及Q4，其中，引脚G3及引脚G4起输出电压的作用。在其中一个实施例中，光伏模块还包括电容C1；
电容C1连接在光伏太阳能板PV的两端。从而通过电容C1可以实现稳压。其中，电容C1可以选用只能存储少量电能电容，从而通过小容量电容就能够实现稳压作用。
在其中一个实施例中，电存储模块还包括电容C2；电容C2连接在储能器的两端。从而通过电容C2可以实现稳压。其中，电容C2可以选用只能存储少量电能电容，从而通过小容量电容就能够实现稳压作用。
在一些实施例中，场效应管Q1的源极及场效应管Q2的漏极与第二场效应管组件201连接。场效应管Q3的源极及场效应管Q4的漏极与第一场效应管组件101连接。
在一些实施例中，还包括：电感L1，第二场效应管组件201与第一场效应管组件101之间通过电感L1连接。从而，通过电感L1，可以实现第二场效应管组件201与第一场效应管组件101之间的稳压。
在其中一个实施例中，储能器为蓄电池bat。蓄电池成本低，存储功率大。
在其中一个实施例中，场效应管Q1、场效应管Q2和负载连接。其中，负载可以为电动自行车、汽车中的至少一种。本公开的储能电源输出直流源，直接给电动自行车、房车或者汽车充电，不需要额外的适配器，充电简单，且高效。在其中一个实施例中，场效应管Q1的漏极和负载连接，场效应管Q2的源极和负载连接。
在其中一个实施例中，直流电压源输出直流电压。直流电压的大小可以结合实际技术场景需求设定，在一些实施例中，直流电压的大小可以为12V、24V、36V、48V、60V及72V中的一种。
PV充电电路的负载需求为12V、24V、36V、48V、60V及72V电压中的一种，由于负载不变，输出电压受电流控制，因此控制器可以通过控制第一场效应管组件、及第二场效应管组件的电流来控制不同大小的直流电压输出，使得PV充电电路输出12V、24V、36V、48V、60V、及72V电压中的一种。本公开利用储能电源内部的PV充电电路，通过控制器模块的控制，可以控制便携储能电源单独输出一个DC恒压源，在不增加系统硬件成本的情况下，能够供更多的负载应用。且通过控制器模块的控制，可以控制便携储能电源的输出12V、24V、36V、48V、60V、72V电压，可以随意临时应急12V、24V、36、48V、60V、72V电动自行车、房车、电动工具、汽车的备用电池的供电，替代没电的电池；由于便携储能电源的容量更大，续航里程更长，电池安全性更高，可以更好的提高消费者的体验。
在其中一个实施例中，参见图1-2，一种可逆向输出直流电压源的PV充电电路，包括：相连接的光伏模块10和电存储模块20；光伏模块10包括：光伏太阳能板PV、电容C1、场效应管Q1、场效应管Q2；电存储模块20包括：电容C2、场效应管Q3、场效应管Q4和储能器；光伏太阳能板PV的两 端连接在电容C1的两端，光伏太阳能板PV的负极还连接至地，光伏太阳能板PV的正极连接场效应管Q1的漏极，场效应管Q1的源极连接场效应管Q2的漏极，场效应管Q2的源极连接光伏太阳能板PV的负极，场效应管Q1的栅极、场效应管Q2的栅极均连接控制器模块；场效应管Q3的漏极连接储能器的正极，场效应管Q3的源极连接场效应管Q4的漏极，场效应管Q4的源极连接储能器的负极，储能器的两端还连接在电容C2的两端，场效应管Q3的源极还连接场效应管Q1的源极，场效应管Q4的源极连接场效应管Q2的源极，场效应管Q3的栅极、场效应管Q4的栅极均连接控制器模块；场效应管Q1的漏极、场效应管Q2的源极还分别作为PV充电电路输出的直流电压源的正极和负极。
如图1和图2中的G1、G2、G3、G4为本申请的控制器模块与本申请的PV充电电路中的四个场效应管的栅极进行连接的引脚。
本实施例的PV充电电路的输出直流电压源的原理是：
光伏太阳能板PV吸收太阳光并转换成电能，通过控制器模块控制场效应管Q1、场效应管Q2、场效应管Q3、场效应管Q4的栅极电压，使得电能经过电容C1、场效应管Q1、场效应管Q2、场效应管Q3、场效应管Q4、电容C2存储在储能器中。
具体地，控制器模块控制场效应管Q1、Q2、Q3及Q4的驱动电压来使电路导通，驱动电压通常为正电压、零压或者负压，以控制器模块控制场效应管Q1及Q4，储能器为bat为例，控制器模块输出正驱动电压至场效应管Q1，控制器模块输出负驱动电压至场效应管Q4，此时可以将场效应管Q1看做高电平，场效应管Q4看做低电平，此时，由于高低电平的电势差可以使PV端的电流向电池存储器bat端流动，bat存储电能。此时的场效应管Q2、 Q3可以不工作，也可以将场效应管Q3控制为低电平或将场效应管Q2控制为高电平，这样就会从场效应管Q3、Q4两边分流输入储能器。本实施例的PV充电电路的输出直流电压源的原理是：
控制器模块控制场效应管Q1、场效应管Q2、场效应管Q3、场效应管Q4的栅极电压，进而控制场效应管Q1、场效应管Q2、场效应管Q3、场效应管Q4的通断情况，使得存储在储能器的电能流出，最终PV充电电路输出直流电压源。且经过控制器模块进一步控制，PV充电电路可以输出不同大小的直流电压源。
具体地，控制器模块控制场效应管Q1、Q2、Q3及Q4的驱动电压来使电路导通，驱动电压通常为正电压、零压或者负压，以控制器模块控制场效应管Q1及Q4，储能器为bat为例，控制器模块输出负驱动电压至场效应管Q1，控制器模块输出正驱动电压至场效应管Q4，此时可以将场效应管Q4看做高电平，场效应管Q1看做低电平，此时，由于高低电平的电势差可以使电池存储器bat端的电流向PV端流动，从而输出直流电压源。此时的场效应管Q2、Q3可以不工作，也可以将场效应管Q2控制为低电平或将场效应管Q3控制为高电平。
