S300、根据初始温度判断是否需要试加热。
在一实施例中，根据初始温度判断是否需要试加热，可以包括：判断初始温度T 0是否在预设加热温度范围内，在初始温度T 0不在预设加热温度范围内的情况下，判断为需要试加热。
在本申请实施例中，预设加热温度范围在35℃-50℃。由于室温下的水温在30℃以下，当监测到预设加热温度为35℃-50℃时，表明水杯内的水最近经过加热正在冷却。并且，从35℃以上降温到35℃以下一般是经过车内空气形成热交换，因此在等待较短时间内即可降低到35℃以下，不会给用户造成不便。
并且，在初始温度T 0大于50℃时，例如初始温度为55℃时，一般为用户明知道水刚加热完毕，仍需要加热，或者需要将水保持在烧开状态，即客户想要使用温度较高的热水，这也符合国内用户的喝热水的习惯，因此仍可执行之后步骤。
需要说明的是，预设加热温度范围能够自行设置，换言之，预设加热温度范围包括两个极值，两个极值是可调的。例如，用户可根据使用习惯通过移动终端或中控屏交互界面执行设置，即当初始温度T 0不在预设加热温度范围时可执行后续加热步骤。
S400、基于需要试加热的判断结果，接收水杯端在试加热时长后的第一温度T 1。即需要试加热后，水杯端开启加热，经过试加热时长后杯座接收第一温度T 1。
在本申请实施例中，试加热时长可以设置为一分钟，即水杯端会加热一分钟。一分钟后杯座接收第一温度T 1，需要说明的是，在一分钟内水杯和杯座之间不间断地执行单向能量传输与双向数据传输，因此该过程也不断接收温度数据，第一温度T 1为一分钟后杯座端处理器接收到的温度数据。以下过程也如上述，在整个加热过程中，不断执行单向能量传输与双向数据(控制指令和反馈数据)传输，水杯会不断反馈温度信息，而杯座会不断执行供电和发出控制指令，以及接收温度信息，加热过程不间断。
S500、根据初始温度T 0、试加热时长t 1、加热功率P、第一温度T 1和预设比热容c判断是否持续加热。
可选地，根据初始温度T 0、试加热时长t 1、加热功率P、第一温度T 1和预设比热容c判断是否持续加热，可以包括：
S501、根据初始温度T 0、预热时长t 1、加热功率P、第一温度T 1和预设比热容c获得实际水量V。
根据公式：P·t 1＝ρ·V·c·(T 1-T 0)。
公式转换后得到V＝P·t 1/[ρ·c·(T 1-T 0)]。
需要说明的是，预设比热容c为水的比热容，加热功率P为汽车出厂设置，ρ为水的密度。
例如，经过计算获得实际水量V为350ml。
步骤S501之后执行步骤S502、判断实际水量V是否大于预设水量V 0。
在本申请实施例中，若预设水量V 0为100ml，实际水量V大于100ml，则表明可以继续加热。即实际水量V大于预设水量V 0，则表明可以继续加热。
若实际水量小于100ml，容易发生干烧。即实际水量V小于预设水量V 0，则容易发生干烧，表明可以执行S900、停止向水杯端供电和发送控制指令，进而完成步骤S901、结束加热。
S600、基于需要持续加热的判断结果，根据第一温度T 1和目标温度T m获得加热到目标温度T m的目标时长t 2。
在本申请实施例中，目标温度T m设置为70℃。
可选地，步骤S600中、基于需要持续加热的判断结果，根据第一温度T 1和 目标温度T m获得加热到目标温度T m的目标时长t 2，可以包括：
S601、基于需要持续加热的判断结果，根据第一温度T 1、目标温度T m、实际水量V和预设比热容c获得所需总热量Q。
可选地，计算公式：Q＝ρ·V·c·(T m-T 1)。根据该计算公式能够得到所需总热量Q。
步骤S601之后执行步骤S602、根据加热功率P和所需总热量Q获得目标时长t 2。
可选地，计算公式：t 2＝Q/P。通过该计算公式能够得到目标时长t 2。例如目标时长t 2为240秒，即四分钟。
S700、接收水杯端在目标时长后的第二温度T 2。
可以理解为四分钟后接收第二温度T 2。
S800、根据第二温度T 2判断是否达到目标温度T m。
S900、基于第二温度T 2达到目标温度T m的判断结果，停止向水杯端供电和发送控制指令。步骤S900之后执行步骤S901、结束加热。
需要说明的是，考虑到车内环境和加热水时的使用习惯，这里默认了在加热过程中不会添加水或车内环境温度急剧降低导致加热速度变慢，因此加热效率能够或必然使得完成加热到目标温度T m。
即杯座端停止发送耦合电磁波，此时水杯被切端信号和能量传输，水杯将不再接收到能量电磁波。
需要说明的是，相关技术中的加热器往往会添加电容，在断电后，水杯端尤其是加热器部分仍然有部分电量，进而还能够维持加热一段时间。
实施例三：
本实施例提供一种车载水杯加热方法，该方法使用上述车载水杯加热装置进行水杯加热，该方法由上述车载水杯加热装置中的水杯(即，水杯端)执行，结合图2和图3所示，该方法包括以下步骤：
S1000、接收杯座端供电和控制指令。
需要说明的是，步骤S1000是对应实施例二中的步骤S100之后，即杯座端的 步骤S100执行后，水杯端执行步骤S1000。
可选地，步骤S1000包括以下步骤：
S1001、水杯端线圈22接收耦合电磁波。
S1002、水杯端控制器21将耦合电磁波解耦为能量电磁波和控制信号电磁波。
S1003、水杯端控制器21将能量电磁波转换为电能并向温度传感器23、继电器25和加热器24供电。
步骤S1000后执行步骤S2000、获取初始温度T 0。换言之，步骤S2000是通过温度传感器23获得初始温度T 0。
可选地，步骤S2000包括以下步骤：
S2001、水杯端控制器21根据控制信号电磁波发送获取初始温度指令。
S2002、温度传感器23根据获取初始温度指令获取初始温度T 0。
S2003、温度传感器23将初始温度T 0发送至水杯端控制器21。
步骤S2000后执行步骤S3000、向杯座端发送初始温度T 0。
步骤S3000可以包括：水杯端控制器21通过水杯端线圈22发送包含初始温度信息的反馈信号电磁波。水杯端执行完步骤S2000后，杯座端执行步骤S200-S300。
步骤S3000后执行步骤S4000、获取试加热时长后的第一温度。需要说明的是，杯座端执行完步骤S300后，水杯端执行步骤S4000。
需要说明的是，水杯和杯座之间的能量传输和信号传输是不间断的，在试加热时长内也在执行数据传输，这里水杯的温度传感器23获取加热时长后的第一温度T 1，和杯座接收的加热时长的第一温度T 1在时间上存在一个时差，但由于该时差极短(一次信号传输的时长)，因此可以认为第一温度T 1与实际无差。
步骤S4000后执行步骤S5000、向杯座端发送第一温度T 1。可以理解为，试加热时长后，水杯端控制器21通过水杯端线圈22发送包含第一温度信息的反馈信号电磁波。
水杯端执行完步骤S5000后执行步骤S6000、获取目标时长后的第二温度T 2， 可选地，水杯端执行完步骤S5000后，杯座端执行步骤S400-S600，水杯端执行步骤S600后，水杯端执行步骤S6000。
可选地，步骤S6000包括：
S6001、到目标时长之时，水杯端控制器21发送获取第二温度指令。
S6002、温度传感器23根据获取第二温度指令获取第二温度T 2。
S6003、温度传感器23将第二温度T 2发送至水杯端控制器21。
步骤S6000后执行步骤S7000、向杯座端发送第二温度T 2。可以理解为，水杯端控制器21通过水杯端线圈22发送包含第二温度信息的反馈信号电磁波。
水杯端执行完步骤S7000后执行步骤S8000、停止接收杯座端供电和控制指令，需要说明的是，水杯端执行完步骤S7000后，相应地，杯座端执行S700-S901,杯座端执行步骤S900后，水杯端执行步骤S8000、停止接收杯座端供电和控制指令。之后执行步骤S9000、结束加热。可以理解为，步骤S9000和步骤S901为同一步骤。
