    Abstract: A protection device for a battery pack, a battery pack and a vehicle are provided. The battery pack comprises a plurality of batteries. The protection device is disposed between two adjacent batteries and comprises: a first connecting assembly, a second connecting assembly and a conductive connecting assembly. The first connecting assembly is opposite to a first battery in the two adjacent batteries, and the first connecting assembly is adapted to be electrically connected with a housing of the first battery. The second connecting assembly is opposite to a second battery in the two adjacent batteries, the second connecting assembly is adapted to be electrically connected with a housing of the second battery, and the second connecting assembly is opposite to the first connecting assembly. The conductive connecting assembly is used for being electrically connected with terminals of the first battery and the second battery, and is adapted to be electrically connected with the first connecting assembly and the second connecting assembly, respectively, to be configured as an overload protection circuit. The protection device has a normal state and an alarm state. When the protection device is in the normal state, the first connecting assembly and the second connecting assembly are spaced apart, and the overload protection circuit is open. When the protection device is in the alarm state, the first connecting assembly is electrically connected with the housing of the first battery, the second connecting assembly is electrically connected with the housing of the second battery, at least one of the first connecting assembly and the second connecting assembly moves to be electrically connected with each other, and the overload protection circuit is closed.
