Abstract: A washing machine comprises a control panel and at least two washing devices, and a control system separately connected with the control panel and the washing devices, wherein the control panel is provided with a knob which can be used as a selection key for selecting one washing device to execute next operation, and also can be used for selecting programs of the washing device, a set of control keys which are shared by the washing devices, and used for controlling the programs and parameters of the corresponding washing device after the washing device is selected by the selection key, and at least two display units corresponding to the washing devices and used for displaying settings and operating states of the washing devices. The washing machine can control and display two washing devices by using only one control panel.

Abstract: A water reuse control method of a multiple-drum washing machine, having a first washing drum and a second washing drum. When the first drum reaches a drainage process, comparing a time for the second drum to reach a water supply process T12 to a time for the first drum to reach a next drainage process T11; if T12<T11, the first drum waits until water is supplied into the second drum; if T12?T11, water in the first drum is directly drained. Alternatively, when the first drum reaches the water supply process, comparing time for the second drum to reach the drainage process T22 to time for the first drum to reach a next water supply process T21; if T22?T21, clean water is directly supplied into the first drum; if T22<T21, the first drum waits until the second drum drains water.

Abstract: Embodiments of the present disclosure provide a battery heating system, a battery assembly and an electric vehicle. The battery heating system includes: a battery group having a positive terminal and a negative terminal; a switch having a first end connected with the positive terminal; a large-current discharge module, and a controller connected to the switch and configured to control the switch according to a temperature of the battery group. A first end of the large-current discharge module is connected to a second end of the switch, and a second end of the large-current discharge module is connected to the negative terminal. When the switch is turned on, the battery group discharges via the large-current discharge module and the battery group is heated due to an internal resistance thereof.
