Description

一种充电设备、电动汽车的充电系统及充电方法
本申请要求于2021年9月14日提交中国专利局、申请号为202111076543.8、申请名称为“一种充电设备、电动汽车的充电系统及充电方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电动汽车的充电控制技术领域，特别涉及一种充电设备、电动汽车的充电系统及充电方法。

在全球能源多元化发展战略大背景下，经过多年的技术沉淀，新能源汽车及其相关配套充电设施正被越来越多的普通消费者接受，电动汽车和充电桩的保有量也越来越大。同时全球新一轮科技革命和产业变革蓬勃发展，如今的汽车消费者已不满足于传统汽车只作为交通运输工具使用，消费形态由物质型向服务型转变，推动新能源汽车在产品形态和用户体验等方面不断追求智能创新。
与传统汽车只能到加油站加油相比，可以在家使用的充电桩大大提高了消费者用车效率，并且充电桩使用频率较高，一般用车平均1至3天就需要充电1次。目前开启和关闭车辆充电座盖口，或者在充电过程中需要停止充电，都需要分别在车端和桩端进行操作，然后还需要把枪拔出放回桩端，繁琐的充电操作使得用户体验较差，反而降低了用车效率。特别地，目前国内外大部分现存的住房修建于数年之前，现有的用电线路或街道区域不能满足安装充电桩的载荷需求，一旦启动充电，充电桩按照最大功率输出，将会导致住宅整体跳闸断电。

所述控制模块111，其与所述充电桩枪头120连接，用于根据所述充电桩枪头120采集到的按压数据输出充电指令，所述控制模块111为所述充电设备100中的核心采集、分析、计算、控制、通信器件，能够实现充电控制和数据 检测等功能，实现对电动汽车200的车辆充电安全的控制和保护。
所述无线通信模块112，其与所述控制模块111连接，用于与所述电动汽车200通信连接并下发充电指令至所述电动汽车200，以使所述电动汽车200控制充电座盖门210的打开和关闭；在本发明实施例中，通过如上述无线通信模块112通知所述电动汽车200控制充电座盖门210在需要充电时自动打开，在不需要充电时自动关闭，能够解决现有传统的电动汽车中用户需要在驾驶舱内弯腰打开充电座盖门的用户体验问题，用户在未携带车辆钥匙时也可以进行充电。
优选地，所述无线通信模块112可以是内嵌在所述充电桩110中的能够与所述电动汽车200实现虚通道标识符(Vehicle Communication Interface,VCI)通信的器件，包括但不限于蓝牙、WiFi、4G等，具体地，可根据实际需要进行设置。进一步地，所述无线通信模块112还能够获取所述电动汽车200的整车数据，所述控制模块111还能够根据所述整车数据判断所述电动汽车200是否存在异常，若未存在异常，则发送充电指令，若存在异常，则发出警告。

进一步地，请参见图2，其示出了本发明实施例提供的另一种充电设备的结构，所述按压检测模块121包括：多通道压力传感器1211、压感模拟前端1212和压感通信模块1213。
由至少两个压力传感器并联组合的所述多通道压力传感器1211，用于接收用户的按压操作；所述多通道压力传感器1211可由压敏电阻和标准电阻串联后再并联而成，类似惠斯通电桥，按压时压敏电阻同向变化，在检测点产生压差，该电路灵敏度非常高，可测出微小的电阻变化，适用于金属、木质、塑料等各种材质表面。所述多通道压力传感器1211所输出的差分信号，该信号随着按压力度增大而增大，随按压力度减小而减小，用户可通过每个压感电压变化时序，判断出用户手指的滑动方向。优选地，所述多通道压力传感器1211粘贴于所述充电桩枪头120内表面，保证产品防尘防水等级设计，设置在用户手握所述充电桩枪头120时大拇指活动区域，从而实现单手握枪时可通过一根指头完成所有操作。
优选地，所述多通道压力传感器1211可设置在用户手持握在所述充电桩枪头120上时，食指或者拇指自然握持住的位置，此时，用户仅需手持握住所述充电桩枪头120，通过在所述充电桩枪头120设置有所述多通道压力传感器1211处进行长按、单击、多击、滑动等动作，即可实现仅使用一个手指头即可完成对充电开始到结束全过程的控制。

具体地，请参见图3，其示出了本发明实施例提供的一种按压检测模块121的硬件电路结构，其为一使用2个压感组合的硬件电路的示例，2个以上压感组合原理相同，在图3中，电源电压为VDD，高精度标准电阻阻值和压敏电阻额定阻值为R ref，按压当前时刻压敏电阻阻值为R t，阻值变化为Δr，则R t＝R ref-Δr，以压力传感器sensor1为例，由此可得当前时刻t压感输出电压信号差为：
Figure PCTCN2022109862-appb-000001
Δr远小于R ref，化简可得：
Figure PCTCN2022109862-appb-000002
其中k为形变系数，ε为等效形变量。
由此可得压力传感器sensor1和sensor2的形变量分别为ε 1和ε 2。当测得ε 1或ε 2值超过一定阈值并恢复，则表示点击了一次；当测得ε 1或ε 2值超过一定阈值并持续一段时间，则表示长按；当测得ε 1超过一定阈值并恢复，接着ε 2超过一定阈值并恢复，则表示从压力传感器sensor1滑动到sensor2，反之同理。
综合考虑用户各种使用习惯，以及对充电功能响应时间的要求，设计单击、多击、滑动、长按对应的典型控制功能如下表1所示，基于此原理可以开发出更多更复杂的人机交互控制逻辑，该控制方式也可在终端设备应用上实现。
