[0132] Embodiment 2

[0133] The present embodiment provides a battery replacing system, which comprises the battery replacing device 1 in the above-mentioned embodiment 1.

[0134] The battery replacement equipment 1 is two, which are a first battery replacement equipment and a second battery replacement equipment, and both of the first battery replacement equipment and the second battery replacement equipment are provided with a spraying unit. The spraying unit of the first battery replacement equipment is located at the side part 101 of the first side of the battery replacement unit 10 thereof, and the spraying unit of the second battery replacement equipment is located at the side part 101 of the second side of the battery replacement unit 10 thereof. The first side and the second side are opposite sides. Through the spraying units arranged at the opposite sides of the first battery replacement equipment and the second battery replacement equipment, the areas on the opposite sides of the electric vehicle can be sprayed respectively. In this way, through arranging the spraying units on different battery replacement equipment 1, the multiple equipment in the battery replacement operation can be utilized comprehensively to arrange reasonably, so as to spray different areas of the electric vehicle.

[0135] The spraying unit is an oil mist spraying unit 100, and the area to be sprayed is two locking mechanisms arranged oppositely in the width direction of the electric vehicle. The first side and the second side are two sides in the width direction of the electric vehicle. The oil mist spraying units 100 of the two battery replacement equipment 1 can spray the two locking mechanisms on the electric vehicle respectively, so that the two locking mechanisms can be maintained normally and prevented from freezing in extremely cold weather.

[0136] Embodiment 3

[0137] The embodiment provides a battery replacement method. The battery replacement method adopts the battery replacement system in the above embodiment 2. The battery replacement system includes a first battery replacement equipment for dismounting a battery and a second battery replacement equipment for mounting a battery. The spraying unit is an oil mist spraying unit 100. The battery replacement method includes the following steps.

[0138] S100: The battery replacement unit 10 of the first battery replacement equipment dismounts a depleted battery on the electric vehicle.

[0139] S200: The oil mist spraying unit 100 of the first battery replacement equipment sprays a locking mechanism on the first side of the electric vehicle.

[0140] S300: The oil mist spraying unit 100 of the second battery replacement equipment sprays a locking mechanism on the second side of the electric vehicle.

[0141] S400: The battery replacement unit 10 of the second battery replacement equipment mounts a full battery to the electric vehicle.

[0142] Through the first battery replacement equipment, the locking mechanism on one side can be sprayed after the depleted battery is dismounted. Through the second battery replacement equipment, the locking mechanism on the other side can be sprayed before the full battery is mounted. Thus, the oil mist spraying maintenance is realized in the battery replacement process.

[0143] In specific implementation, the oil mist spraying function of the battery replacing device 1 can be realized by PLC control, and the electric vehicle can be maintained regularly, and the oil mist spraying amount can be controlled by PLC control spraying time. Thus, it can reduce the manual participation in maintenance, reduce the maintenance cost; and the locking mechanism is maintained at the same time of battery replacement, which can save the maintenance time and cost. In addition, it can be considered to be carried out in good weather, which has less influence on operation and better spraying effect. In addition, the function is beneficial to the normal operation of the locking mechanism in extremely cold weather, and the low-temperature engine oil mist can prevent the locking mechanism from freezing, reduce the possibility of poor battery replacement caused by the freezing of the locking mechanism in extremely cold weather, thereby improving the battery replacement efficiency and prolonging the service life. Therefore, the oil mist spraying frequency can be increased before the arrival of extremely cold weather and in cold weather. In addition, the oil mist spraying is relatively controllable in the use of oil amount, which is lower in cost and better in vehicle protection, and can effectively avoid the influence of oil maintenance dripping on the vehicle, battery replacement station and road surface environment.
