Embodiments of this application provide a direct current contactor and a vehicle. The direct current contactor includes a case and two groups of contact components disposed in the case. Each group of contact components includes two moving contacts connected to each other and two fixed contacts. The direct current contactor further includes a drive system configured to drive the moving contacts to move in a direction close to or away from the fixed contacts, so that the moving contacts are connected to or disconnected from the fixed contacts. The case has an arc-extinguishing cavity. A first baffle in the arc-extinguishing cavity divides the arc-extinguishing cavity into a first arc-extinguishing chamber and a second arc-extinguishing chamber. The contact components are respectively located in the first arc-extinguishing chamber and the second arc-extinguishing chamber. In other words, the two groups of contact components are integrated into two arc-extinguishing chambers of one arc-extinguishing cavity, and perform connection/disconnection drive by using a single drive system, so that a structure of the direct current contactor is simplified. In addition, connection/disconnection requirements of a positive line and a negative line can be met by using one direct current contactor, and there is no need to mount one contactor on each of the positive line and the negative line. This reduces a volume of a charging apparatus, and reduces manufacture costs.
