The invention discloses a vehicle battery replacement method, system and device based on a digital currency hardware wallet. The method comprises the steps that when it is determined that a first battery used for supplying power to a target vehicle is to be replaced, a battery replacement instruction is sent to a first control module associated with the first battery, so that the first control module determines a battery replacement refund instruction based on the remaining electric quantity of the first battery, and the battery replacement refund instruction is sent to a first digital currency hardware wallet arranged on the first battery; the first digital currency hardware wallet is used for refund to a second digital currency hardware wallet set by the target vehicle; when it is determined that the first battery is separated from the target vehicle, a battery replacement instruction is sent to a second control module associated with a second battery located in the battery replacement station, so that the second control module sends a battery replacement payment instruction to a second digital currency hardware wallet; and the second digital currency hardware wallet is used for paying for a third digital currency hardware wallet set by the second battery. Therefore, the battery replacement failure caused by poor network communication capability can be avoided, and the battery replacement success rate and the battery replacement flexibility are improved.

本申请公开了一种基于数字货币硬件钱包的车辆换电方法、系统及设备。该方法包括：确定用于向目标车辆供电的第一电池待换电时，向第一电池关联的第一控制模块发送换电指令，以便第一控制模块基于第一电池的剩余电量确定换电退款指令，并发送至第一电池设置的第一数字货币硬件钱包；第一数字货币硬件钱包用于向目标车辆设置的第二数字货币硬件钱包退款；确定第一电池脱离目标车辆时，向位于换电站的第二电池关联的第二控制模块发送换电指令，以便第二控制模块向第二数字货币硬件钱包发送换电付款指令；第二数字货币硬件钱包用于向第二电池设置的第三数字货币硬件钱包付款。如此可以避免网络通信能力差造成的换电失败，提高换电成功率和换电灵活性。
