本实施例中，电池锁只有在接收到安全报文时，才解锁电池，实现电池与电动车电连接，而当用户私自更换电池时，电池锁无法获得该安全报文，也就不能解锁安装于电动车上的电池，电动车无法运行。从而，实现了对电池的有效监管，避免电池被偷换、错换。
具体的，如图1所示，本实施例的电池锁包括：接收单元1、锁定单元2、发送单元3、解锁单元4和存储单元5。接收单元1分别与锁定单元2、解锁单元4和存储单元5电连接，发送单元3分别与锁定单元2和存储单元5电连接。
当电动车在换电站换电时，换电站的换电设备将电池从电动车上拆卸，电池的解锁机构生成电池开锁信号并发送至电池锁。其中，电池开锁信号用于表征电池从电动车上拆除。
电池锁的接收单元1在接收到电池开锁信号时，调用锁定单元2以锁定电池，使电池与电动车断开电连接，此时电动车无法正常运行。
换电设备将电池从电动车取下后，锁定单元2还调用发送单元3以将存储于存储单元5中的安全 报文发送至换电设备(外部设备以换电设备为例)。该安全报文是上一次电动车在换电站给电池充电时，换电设备发送的。
换电设备验证该安全报文，以确定电池是否合法。若验证通过，换电设备将充好电的电池安装至电动车上。在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并发送至电池锁。其中，电池锁止信号用于表征电池安装至电动车上。
电池锁的发送单元3将获取的电池锁止信号发送至换电设备，换电设备生成新的安全报文并发送至电池锁。
电池锁的接收单元1在接收到新的安全报文时，调用解锁单元4以解锁电池，使电池与电动车电连接，此时电动车可正常运行。
本实施例中，接收单元1在接收到新的安全报文后还发送给存储单元5以存储该新的安全报文。当电动车再次在换电站换电时，电池锁将该新的安全报文提供给换电设备，以验证电池的合法性。至此，完成电动车的换电。
实施例2
本实施例提供一种电池锁的控制方法，该电池锁适用于电动车的电池更换。本实施例的控制方法包括：电池锁在接收到外部设备发送的安全报文时解锁电池，使电池与电动车电连接。其中，外部设备可以是换电设备或换电站。
本实施例中，如图2所示，控制方法具体包括以下步骤：
步骤101、电池锁在接收到电池开锁信号时，锁定电池。
其中，电池开锁信号用于表征电池从电动车上拆除。当电动车在换电站换电时，换电站的换电设备将电池从电动车上拆卸，电池的解锁机构会生成电池开锁信号并发送至电池锁。
步骤102、电池锁将安全报文发送至换电设备。
本实施例中，外部设备以换电设备为例。电池锁将安全报文发送至换电设备，供换电设备验证电池的合法性。该安全报文是上一次电动车在换电站给电池充电时，换电设备发送的。
换电设备在验证通过时，将充好电的电池安装至电动车上。在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并发送至电池锁。其中，电池锁止信号用于表征电池安装至电动车上。
步骤103、电池锁将获取的电池锁止信号发送至换电设备。
电池锁将电池锁止信号发送至换电设备，供其生成新的安全报文。换电设备将生成的新的安全报文发送至电池锁。
步骤104、电池锁在接收到换电设备发送的新的安全报文时解锁电池。
电池锁解锁电池后，电池与电动车电连接，此时电动车可正常运行。
步骤105、电池锁存储新的安全报文。
当电动车再次在换电站换电时，电池锁将该新的安全报文提供给换电设备，以验证电池的合法性。至此，完成电动车的换电。
本实施例的换电加密系统，对电动车的电池更换实现了有效的监管，从而保证换电站(换电运营商)的电池在其自己的系统内部流通，避免电池被偷换、错换，提高了汽车运行的安全性。

具体的，如图3所示，本实施例的换电设备包括：拆装单元1’、验证单元2’、发送单元3’、接收单元4’、报文生成单元5’和报警单元6’。验证单元2’分别与拆装单元1’、发送单元3’和报警单元6’电连接，报文生成单元5’分别与发送单元3’和接收单元4’电连接。
当电动车在换电站换电时，换电设备的拆装单元1’将电池从电动车上拆卸。拆卸后，电池的解锁机构生成电池开锁信号并发送至电池的电池锁。其中，电池开锁信号用于表征电池从电动车上拆除。电池锁在获取到电池开锁信号时，锁定电池，使电池与电动车断开电连接，此时电动车无法正常运行。
拆装单元1’将电池从电动车上取下后，验证单元2’获取并验证该电池的电池锁的安全报文，以确定电池是否合法。该安全报文是上一次电动车在换电站给电池充电时，换电设备发送给电池锁的。
若验证单元2’验证安全报文未通过，说明该电池可能是被偷换的劣势电池，则验证单元2’调用报警单元6’以生成报警信息，提示该电池并非是换电站系统内部流通的电池。
若验证单元2’验证安全报文通过，说明该电池是换电站系统内部流通的优质电池，则验证单元2’调用发送单元3’将生成的安全信号发送至换电站的电池充电设备，以给该电池充电。
验证单元2’在验证电池合法性通过时，拆装单元1’将充好电的电池安装至电动车上。在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并通过电池锁发送至换电设备。其中，电池锁止信号用于表征电池安装至电动车上。
换电设备的接收单元4’在接收到电池锁发送的电池锁止信号时，调用报文生成单元5’以生成新的安全报文。报文生成单元5’调用发送单元3’将新的安全报文发送给电池锁，实现电池解锁，使电池与电动车电连接，此时电动车可正常运行。
本实施例中，若电池是合法的，但是电池安装至电动车后，电动车无法正常运行，用户则可通过电话、短信、邮件或其他方式发送解锁请求至换电设备。其中，解锁请求包括用户身份和标识。接收单元4’还用于在接收到解锁请求时，调用验证单元2’以验证用户身份和目标电池的标识，并在验证通过时调用报文生成单元5’以生成安全报文。报文生成单元5’发送安全报文至目标电池，实现目标电池解锁。
本实施例的换电设备可发送安全报文给电池的电池锁，电池锁只有在接收到安全报文时才解锁电池，从而换电设备通过与电池锁的交互，实现了对电动车的电池更换的有效监管，进而保证换电站(换电运营商)的电池在其自己的系统内部流通，避免电池被偷换、错换，提高了汽车运行的安全性。

本实施例中，如图4所示，控制方法具体包括以下步骤：
步骤101’、换电设备拆卸电动车上的电池。
当电动车在换电站换电时，换电设备将电池从电动车上拆卸。拆卸后，电池的解锁机构生成电池开锁信号并发送至电池的电池锁。其中，电池开锁信号用于表征电池从电动车上拆除。电池锁在获取到电池开锁信号时，锁定电池，使电池与电动车断开电连接，此时电动车无法正常运行。
步骤102’、换电设备获取并验证电池锁的安全报文。
若验证未通过，说明该电池可能是被偷换的劣势电池，则执行步骤103’。
步骤103’、换电设备生成报警信息。
以提示该电池并非是换电站系统内部流通的电池。
若验证通过，说明该电池是换电站系统内部流通的优质电池，则执行步骤104’。
步骤104’、换电设备生成安全信号并发送至换电站的电池充电设备，以给该电池充电。然后执行步骤105’。
步骤105’、换电设备将电池安装至电动车上。
在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并通过电池锁发送至换电设备。其中，电池锁止信号用于表征电池安装至电动车上。
步骤106’、换电设备在接收到电池锁发送的电池锁止信号时，生成新的安全报文并发送至电池锁。
电池锁在接收到该新的安全报文时解锁电池，使电池与电动车电连接，此时电动车可正常运行。
本实施例中，若电池是合法的，但是电池安装至电动车后，电动车无法正常运行，用户则可通过电话、短信、邮件或其他方式发送解锁请求至换电设备。其中，解锁请求包括用户身份和标识。具体的，控制方法还包括：
换电设备在接收到解锁请求时，验证用户身份和目标电池的标识，并在验证通过时发送安全报文至目标电池的电池锁，实现目标电池解锁。
本实施例对电动车的电池更换实现了有效的监管，从而保证换电站(换电运营商)的电池在其自己的系统内部流通，避免电池被偷换、错换，提高了汽车运行的安全性
实施例5
本实施例提供一种换电加密系统，用于电动车的电池更换，如图5所示，本实施例的换电加密系统包括：换电设备1”和电池锁2”，换电设备1”与电池锁2”电连接。电池锁设置于电动车中。
以下对换电加密系统的工作原理进行说明：
换电设备拆卸需要换电的电动车上的电池。电池从电动车上拆卸后，电池的解锁机构生成电池开锁信号并发送至电池锁。其中，电池开锁信号用于表征电池从电动车上拆除。电池锁在获取到电池开锁信号时，锁定电池，使电池与电动车断开电连接，此时电动车无法正常运行。
换电设备将电池从电动车取下后，获取并验证该电池的电池锁的安全报文，以确定电池是否合法。该安全报文是上一次电动车在换电站给电池充电时，换电设备发送的。
若换电设备验证安全报文未通过，说明该电池可能是被偷换的劣势电池，则换电设备生成报警信息，提示该电池并非是换电站系统内部流通的电池。
若换电设备验证安全报文通过，说明该电池是换电站系统内部流通的优质电池，则换电设备生成安全信号并发送至换电站的电池充电设备，以给该电池充电。
换电设备将充好电的电池安装至电动车上，在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并发送至电池锁。其中，电池锁止信号用于表征电池安装至电动车上。
电池锁将获取的电池锁止信号并发送至换电设备，换电设备在接收到电池锁止信号时生成新的安全报文并发送至电池锁。电池锁在接收到新的安全报文时解锁电池，使电池与电动车电连接，此时电动车可正常运行。
本实施例中，电池锁还用于该新的存储安全报文。当电动车再次在换电站换电时，将该新的安全报文提供给换电设备，以验证电池的合法性。
本实施例中，若电池是合法的，但是电池安装至电动车后，电动车无法正常运行，用户则可通过电话、短信、邮件或其他方式发送解锁请求至换电站。其中，解锁请求包括用户身份和标识。换电站的换电设备在接收到该解锁请求时，验证用户身份和目标电池的标识，并在验证通过时发送安全报文至目标电池的电池锁，实现目标电池解锁。
本实施例的换电加密系统，对电动车的电池更换实现了有效的监管，从而保证换电站(换电运营商)的电池在其自己的系统内部流通，避免电池被偷换、错换，提高了汽车运行的安全性。
实施例6
本实施例提供一种换电加密方法，用于实现电动车的电池更换，如图6所示，换电加密方法包括以下步骤：
步骤201、换电设备将电池安装至电动车上，并发送安全报文至电池锁。
步骤202、电池锁在接收到安全报文时解锁电池，使电池与电动车电连接。
本实施例中，只有在换电设备给电池锁发送安全报文时，电池锁才解锁电池，而当用户私自更换 电池时，电池锁无法获得该安全报文，也就不能解锁安装于电动车上的电池，电动车无法运行。从而，实现了对电池的有效监管，避免电池被偷换、错换。
实施例7
实施例7与实施例6基本相同，不同之处在于，当给电动车换电时，换电设备将电池拆卸后还验证其合法性，本实施例的换电加密方法的步骤具体参见图7：
步骤301、换电设备拆卸电动车上的电池。
电池从电动车上拆卸后，电池的解锁机构生成电池开锁信号并发送至电池锁。其中，电池开锁信号用于表征电池从电动车上拆除。
步骤302、电池锁在获取到电池开锁信号时，锁定电池。
此时，电池锁锁定电池后，电池与电动车断开电连接，此时电动车无法正常运行。
步骤303、电池锁将安全报文发送至换电设备。
其中，该安全报文是上一次电动车在换电站给电池充电时，换电设备发送的。
步骤304、换电设备获取并验证该电池的电池锁的安全报文。
步骤304的目的是验证该电池是否合法，是否被偷换。步骤304中，若验证未通过，说明该电池可能是被偷换的劣势电池，则换电设备生成报警信息，提示该电池并非是换电站系统内部流通的电池；若验证通过，说明该电池是换电站系统内部流通的优质电池，则换电设备生成安全信号并发送至换电站的电池充电设备，以给该电池充电，并执行步骤305。
步骤305、换电设备将充好电的电池安装至电动车上。
在确认电池已经安装在电动车上时，电池的锁止机构生成电池锁止信号并发送至电池锁。其中，电池锁止信号用于表征电池安装至电动车上。
步骤306、电池锁获取电池锁止信号。
步骤307、电池锁将电池锁止信号发送至换电设备。
步骤308、换电设备在接收到电池锁止信号时生成新的安全报文。
步骤309、换电设备将新的安全报文发送至电池锁。
步骤310、电池锁在接收到新的安全报文时，解锁电池。
电池锁解锁电池后，电池与电动车电连接，此时电动车可正常运行。
本实施例中，步骤310之后，还包括：
步骤311、电池锁存储该新的安全报文。
当电动车再次在换电站换电时，将该新的安全报文提供给换电设备，换电设备执行步骤304，也即验证电池的合法性。
本实施例中，若电池是合法的，但是电池安装至电动车后，电动车无法正常运行，用户则可通过 电话、短信、邮件或其他方式发送解锁请求至换电站。其中，解锁请求包括用户身份和标识。具体的，换电加密方法还包括：
换电站的换电设备在接收到解锁请求时，验证用户身份和目标电池的标识，并在验证通过时发送安全报文至目标电池的电池锁，实现目标电池解锁。
本实施例的换电加密方法，对电动车的电池更换实现了有效的监管，从而保证换电站(换电运营商)的电池在其自己的系统内部流通，避免电池被偷换、错换，提高了汽车运行的安全性。
