具体实施方式
为了使本技术领域的人员更好地理解本说明书中的技术方案，下面将结合本说明书实施例中的附图，对本说明书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说明书一部分实施例，而不是全部的实施例。基于本说明书中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都应当属于本说明书保护的范围。
本说明书实施例提及的电子锁一般是指：新能源车车载充电装置(即新能源车的车载充电装置)上配置的电子锁，其可以包括插座锁和/或封盖锁。其中，插座锁可以在新能源车充电时，将充电头锁止固定在新能源车车载充电装置上，从而保证新能源车充电过程中，充电头可与新能源车车载充电装置之间始终维持良好的连接。封盖锁可以用于 锁住封盖新能源车车载充电装置的盖板，以起到防护新能源车车载充电装置的作用；当需要对新能源车进行充电时，封盖锁解锁，盖板打开。
鉴于现有新能源车车载充电装置在非充电状态下仍具有相对较高的功耗的问题，本说明书实施例提供了改进的新能源车车载充电装置的电子锁控制电路。其中，非充电状态可以包括：充电头未插入新能源车车载充电装置下的非充电状态；以及新能源车满充且未拔出充电头下的非充电状态。
参考图1所示，在一些实施例中，新能源车车载充电装置的电子锁控制电路可以包括开关管10、控制单元20、插座锁驱动电路30和封盖锁驱动电路40。
开关管10的输出端分别与所述插座锁驱动电路30及所述封盖锁驱动电路40的供电输入端连接，在所述开关管10处于导通状态时，所述插座锁驱动电路30和所述封盖锁驱动电路40得电(即接通电源)，在所述开关管10处于截止状态时，所述插座锁驱动电路30和所述封盖锁驱动电路40失电(即断开电源)。
控制单元20的开关控制端可与所述开关管10的控制接收端连接，控制单元20用于在确认新能源车处于非充电状态时，中止向所述开关管10输出导通控制信号，以使所述开关管10处于截止状态；如此，开关管10则切断了所述插座锁驱动电路30和所述封盖锁驱动电路40的电源，所述插座锁驱动电路30和所述封盖锁驱动电路40停止待机状态，从而节省了新能源车处于非充电状态下，控制单元20仍向插座锁驱动电路30和封盖锁驱动电路40输出导通控制信号，以及插座锁驱动电路30和封盖锁驱动电路40仍处于待机状态下的电能消耗，从而降低了新能源车车载充电装置在非充电状态下的功耗。不仅如此，这种降低静态功耗的方式还可以延长电子锁控制电路的工作寿命；而且，由于驱动电路(即插座锁驱动电路30和封盖锁驱动电路40)不是一直保持被供电状态，也会降低驱动电路对外的辐射，进而还可以有利于降低测新能源车的总辐射。
在一些实施例中，控制单元20可以通过检测新能源车的充电状态判断新能源车是否处于非充电状态。例如，当检测到新能源车当前已处于满充状态时，可以确认新能源车处于非充电状态。在另一些实施例中，控制单元20也可以通过检测插座锁和/或封盖锁的状态判断新能源车是否处于非充电状态。例如，以插座锁为例，当检测到插座锁处于解锁状态时，表明当前并无充电头插入新能源车车载充电装置，据此可以确认新能源车处于非充电状态。再如，以封盖锁为例，当检测到处于加锁状态时，表明当前新能源车车载充电装置被盖板封盖，无充电头插入新能源车车载充电装置，据此也可以确认新能源车处于非充电状态。当然，在其他实施例中，也可以综合利用检测插座锁和封盖锁的 状态判断新能源车是否处于非充电状态，以提高判断的准确性。
插座锁和封盖锁一般利用电动机(即电动马达)执行加、解锁动作，因此，插座锁和封盖锁均需要配置相应的电机驱动电路，以对应驱动插座锁电动机和封盖锁电动机执行加、解锁动作；因此，插座锁的电机驱动电路可以称为插座锁驱动电路30，封盖锁的电机驱动电路可以称为封盖锁驱动电路40。在一些实施例中，插座锁驱动电路30和封盖锁驱动电路40可以为集成的电机驱动模块(例如电机驱动芯片等)。例如，在如图4所示的实施例中，插座锁驱动电路30可以采用电机驱动芯片U1，封盖锁驱动电路40可以采用电机驱动芯片U2。由于本说明书实施例并不涉及插座锁驱动电路30和封盖锁驱动电路40部分的改进，对此不再赘述。
开关管10是指三极管等内阻微小的可控半导体器件，通过使用内阻微小的开关管10作为电子开关，能使此部分压降控制在很小的范围内，从而不至于影响后端驱动电路的供电电压，还能满足新能源车不充电时的静态功耗要求。在一些实施例中，三极管可以为双极型晶体管(Bipolar Junction Transistor，BJT)，结型栅场效应晶体管(Junction Field-Effect Transistor，JFET)，金属氧化物半导体场效应晶体管(Metal Oxide Semi-Conductor Field Effect Transistor，MOS FET)或V型槽MOS场效应管(V-groove metal-oxide semiconductor，VMOS)等，具体可以根据实际应用场景的需要选择。
例如，在如图4所示的实施例中，开关管10可以为N沟道增强型MOS场效应晶体管(以下简称MOS管)Q1。MOS管Q1的漏极(如图4中的30F_IN端)与电源连接，MOS管Q1的源极分别与插座锁驱动电路30及封盖锁驱动电路40的供电输入端连接，MOS管Q1的栅极通过分压电路与所述控制单元的开关控制端(图4中的LOCK_PWR_EN端)连接。
如图4所示，在一些实施例中，分压电路可以包括第一分压电阻R4和第二分压电阻R5，所述第一分压电阻R4的一端与所述控制单元的开关控制端连接，所述第一分压电阻R4的另一端与所述第二分压电阻R5的一端连接，所述第二分压电阻R5的另一端接地，所述第一分压电阻R4与所述第二分压电阻R5之间的连接点与MOS管Q1的栅极连接。如此，由第一分压电阻R4和第二分压电阻R5组成的分压电路，可以为MOS管Q1的漏极提供直流电压，即建立了MOS管Q1的漏极的直流偏置电压，因此，上述分压电路也可以称为分压式直流偏置电路。
控制单元20是整个新能源车车载充电装置的控制和处理中心，在一些实施例中，控制单元20可以包括但不限于单片机、微控制单元(Microcontroller Unit，简称MCU)、 微处理器(Microprocessor Unit，MPU)、数字信号处理器(Digital Signal Processing，DSP)、可编程逻辑控制器(Programmable Logic Controller，PLC)等等。
结合图2所示，在另一些实施例中，所述控制单元20还设置有第一驱动控制端和第二驱动控制端，所述第一驱动控制端与所述插座锁驱动电路30的第一驱动接收端连接，所述第二驱动控制端与所述封盖锁驱动电路40的第二驱动接收端连接。相应地，所述控制单元20还可以用于：在确认新能源车需要充电时，向所述开关管10输出导通控制信号，以使所述开关管10处于导通状态；并向所述插座锁驱动电路30和/或所述封盖锁驱动电路40输出驱动信号，以使所述插座锁驱动电路30和所述封盖锁驱动电路40据此对应驱动插座锁电动机、封盖锁电动机，进而实现加、解锁。
所述控制单元20向所述插座锁驱动电路30和/或所述封盖锁驱动电路40输出驱动信号是指：根据控制逻辑不同，所述控制单元20可以选择性向所述插座锁驱动电路30和/或所述封盖锁驱动电路40输出驱动信号。例如，当仅需要打开新能源车车载充电装置封盖时，所述控制单元20可以仅向所述封盖锁驱动电路40输出驱动信号，并在确认新能源车车载充电装置封盖已被打开时，停止向所述封盖锁驱动电路40输出驱动信号；在新能源车车载充电装置封盖已被打开的情况下，当有充电头插入新能源车车载充电装置时，所述控制单元20可以仅向所述插座锁驱动电路30输出驱动信号，以将充电头锁止于新能源车车载充电装置上，并在确认充电头已被锁止于新能源车车载充电装置上时，停止向所述插座锁驱动电路30输出驱动信号，等等。
在一些实施例中，所述控制单元20可以在收到充电指示时，确认新能源车需要充电。例如，当检测到有充电头插入新能源车车载充电装置时，相当于收到充电指示。当然，这里仅是示例性举例说明，在其他实施例中，任何可以使控制单元20识别出用户要对新能源车充电的状态或事件，均可以视为所述控制单元20收到充电指示。因此，本说明书对此不作唯一限定。
在一些实施例中，所述控制单元20还设置有第一反馈接收端和第二反馈接收端，所述第一反馈接收端与所述插座锁驱动电路30的第一状态反馈端连接，所述第二反馈接收端与所述封盖锁驱动电路40的第二状态反馈端连接。因此，所述控制单元20还可以用于：在接收到所述插座锁驱动电路30反馈的第一自保护状态信号和/或所述封盖锁驱动电路40反馈的第二自保护状态信号时，根据所述第一自保护状态信号和/或所述第二自保护状态信号进行自保护判定。
在一些实施例中，根据所述第一自保护状态信号和/或所述第二自保护状态信号进行 自保护判定可以包括：当接收到第一自保护状态信号时，可以停止向所述插座锁驱动电路30输出驱动信号；当接收到第二自保护状态信号时，可以停止向所述封盖锁驱动电路40输出驱动信号；当接收到第一自保护状态信号和第二自保护状态信号时，可以停止向所述插座锁驱动电路30和所述封盖锁驱动电路40输出驱动信号，或者中止向所述开关管10输出导通控制信号。
请继续参考图1或图2所示，在一些实施例中，插座锁驱动电路30和封盖锁驱动电路40可以选用内部集成驱动+H桥电路、实时电流反馈、自保护状态信号输出等功能的集成芯片，其中，自保护可以包括但不限于过欠压保护、过流保护、过温保护等。例如，以图4所示的实施例为例，电机驱动芯片U1和电机驱动芯片U2的引脚功能如下：GND为参考地端；IN2/IN3作为驱动接收端，与控制单元20的驱动控制端连接；nFAULT作为状态反馈端，与控制单元20的反馈接收端连接，以向控制单元20反馈自保护状态信号；VM为供电输入端，与MOS管Q1的源极连接；OUT1和OUT2作为驱动输出端，通过电平高低组合来控制正、负极输出及输出方向，达到控制加锁与解锁的驱动控制目的；ISEN作为检流电阻端，可以用检测锁状态(例如是否加锁成功，是否解锁成功等)，如不需要此功能，可以将检流电阻端接地。
当插座锁驱动电路30或封盖锁驱动电路40检测到自身出现欠压、过流和/或过温等异常时，可以通过自身的状态反馈端向控制单元20输出自保护状态信号。但是，在某些情况下，插座锁驱动电路30和封盖锁驱动电路40的状态反馈端可能因外部干扰等原因意外输出自保护状态信号(即输出了误保护信号)，进而使得控制单元20误以为插座锁驱动电路30或封盖锁驱动电路40出现故障，而停止驱动或供电，从而可能影响充电进程。
因此，参考图3所示，在另一些实施例中，新能源车车载充电装置的电子锁控制电路还可以包括第一自保护输出滤波电路61和第二自保护输出滤波电路62。其中，第一自保护输出滤波电路61可以设置于所述第一反馈接收端与所述第一状态反馈端之间，用于对所述第一自保护状态信号进行电平滤波，以滤除插座锁驱动电路30的误保护信号；第二自保护输出滤波电路62可以设置于所述第二反馈接收端与所述第二状态反馈端之间，用于对所述第二自保护状态信号进行电平滤波，以滤除封盖锁驱动电路40的误保护信号。
结合图4所示，在另一些实施例中，所述第一自保护输出滤波电路61可以包括第一上拉电阻R3和第五电容C3，所述第一上拉电阻R3的一端与所述第五电容C3的一端连 接，所述第一上拉电阻R3的另一端接电源电压，所述第五电容C3的另一端接地，所述第一上拉电阻R3的一端与所述第五电容C3之间的连接点与所述第一状态反馈端连接。所述第二自保护输出滤波电路62可以包括第二上拉电阻R8和第六电容C6，所述第二上拉电阻R8的一端与所述第六电容C6的一端连接，所述第二上拉电阻R8的另一端接电源电压，所述第六电容C6的另一端接地，所述第二上拉电阻R8的一端与所述第六电容C6之间的连接点与所述第二状态反馈端连接。
结合图2所示，在另一些实施例中，新能源车车载充电装置的电子锁控制电路还可以包括第一输出接口保护电路51和第二输出接口保护电路52。其中，第一输出接口保护电路51可以设置于所述插座锁驱动电路30的输出端与插座锁接线端子之间，用于泄放所述插座锁驱动电路30的输出端感应电动势，并滤除该输出端的静电泄放干扰。第二输出接口保护电路52可以设置于所述封盖锁驱动电路40的输出端与封盖锁接线端子之间，用于泄放所述封盖锁驱动电路40的输出端感应电动势，并滤除该输出端的静电泄放干扰。
结合图5所示，在一些实施例中，所述第二输出接口保护电路52可以包括第一电容C1、第二电容C2、第一钳位二极管D1和第二钳位二极管D2。所述第一电容C1的一端与所述第一钳位二极管D1的一端相连，所述第一电容C1的另一端及所述第一钳位二极管D1的另一端接地，所述第一电容C1与所述第一钳位二极管D1之间的连接点与所述封盖锁驱动电路40的负极输出端(即图5中的F_LK-)连接。所述第二电容C2的一端与所述第二钳位二极管D2的一端相连，所述第二电容C2的另一端及所述第二钳位二极管D2的另一端接地，所述第二电容C2与所述第二钳位二极管D2之间的连接点与所述封盖锁驱动电路40的正极输出端(即图5中的F_LK+)连接。
请继续结合图5所示，在一些实施例中，所述第一输出接口保护电路51可以包括第三电容C4、第四电容C5、第三钳位二极管D3和第四钳位二极管D4。所述第三电容C4的一端与所述第三钳位二极管D3的一端相连，所述第三电容C4的另一端及所述第三钳位二极管D3的另一端接地，所述第三电容C4与所述第三钳位二极管D3之间的连接点与所述插座锁驱动电路30的负极输出端(即图5中的C_LK-)连接。所述第四电容C5的一端与所述第四钳位二极管D4的一端相连，所述第四电容C5的另一端及所述第四钳位二极管D4的另一端接地，所述第四电容C5与所述第四钳位二极管D4之间的连接点与所述插座锁驱动电路30的正极输出端(即图5中的C_LK+)连接。
其中，上述的第一钳位二极管D1、第二钳位二极管D2、第三钳位二极管D3和第 四钳位二极管D4可以为TVS(Transient Voltage Suppressor，瞬态二极管)钳位二极管。如此，通过设置第一钳位二极管D1、第二钳位二极管D2、第三钳位二极管D3和第四钳位二极管D4，可以抑制接口处(即驱动电路输出端接口)的静电释放干扰，并协助电子锁线圈的感应电动势及时泄放，保护前级驱动电路；而通过设置第一电容C1、第二电容C2、第三电容C4和第四电容C5这个四个滤波电容，还可以抑制接口处窜入的高频干扰。其中，静电释放干扰是指锁安装时、电路板组装时、或复杂条件下工作时等情况下的外界静电干扰。感应电动势是指锁自身引入的感应电动势的传导干扰和辐射干扰；感应电动势会通过锁接线端子串入到电路内部，从而可以会损坏电路，通过钳位二极管可将感应电动势过高的电压/电流导入到GND，而不至于损伤电路内部元件。
请继续结合图5所示，在一些实施例中，插座锁接线端子与封盖锁接线端子可以共用一个集成端子70，以简化结构；所述插座锁驱动电路30的正、负极输出端(即图5中的C_LK+、C_LK-)对应与所述集成端子70的第一端、第二端相连，所述封盖锁驱动电路40的正、负极输出端(即图5中的F_LK+、F_LK-)对应与所述集成端子70的第三端、第四端相连。
