The electric vehicle is equipped with a power battery pack to provide electric energy for driving the vehicle. In consideration of the cruising range and lightweight design requirements of the electric vehicle, the wall thickness of the power battery pack is usually thinned, and a large Most of the power battery packs are arranged under the floor of the vehicle, which makes the power battery packs extremely vulnerable to impacts during driving, and in severe cases, the battery packs may rupture. In the prior art, when the power battery packs are hit, the owner often cannot Discovered in time, there is a big security risk

The invention discloses an alarm device of a battery pack, a battery pack assembly and a vehicle. The alarm device of a battery pack comprises a power supply; a lower case, wherein a bottom wall of the battery pack is formed by the lower case; a water cooling plate, wherein the water cooling plate and the lower case are arranged at an interval, one of the water cooling plate and the lower case iselectrically connected with a positive electrode of the power supply, the other one of the water cooling plate and the lower case is electrically connected with a negative electrode of the power supply, and the water cooling plate is electrically connected with the lower case when the bottom of the battery pack is impacted; and a control module which is electrically connected with the power supply, wherein the control module outputs an alarm signal when it is identified by the control module that the water cooling plate is electrically connected with the lower case. According to the alarm device of the battery pack, a vehicle owner can be reminded in time when the battery pack is impacted, so that the vehicle owner finds that the battery pack is damaged as soon as possible, effective safety treatment measures are taken, and the safety of a vehicle in the running process is guaranteed.
Description
technical field [0001] The present application relates to the technical field of power battery manufacturing, and in particular to an alarm device for a battery pack, a battery pack assembly with the alarm device, and a vehicle with the battery pack assembly. Background technique [0002] With the development and progress of automobile technology, more and more electric vehicles are gradually replacing traditional fuel vehicles. The electric vehicle is equipped with a power battery pack to provide electric energy for driving the vehicle. In consideration of the cruising range and lightweight design requirements of the electric vehicle, the wall thickness of the power battery pack is usually thinned, and a large Most of the power battery packs are arranged under the floor of the vehicle, which makes the power battery packs extremely vulnerable to impacts during driving, and in severe cases, the battery packs may rupture. In the prior art, when the power battery packs are hit,...
