Abstract

The invention relates to a water leakage induction device, a battery pack and an electric automobile. The water leakage induction device comprises a processor, a water leakage induction cable, a firstvoltage detection device and a power supply. The water leakage induction cable comprises a first induction cable and a second induction cable. The first voltage detection device is also connected with the processor. The positive electrode of the power supply is connected with the first end of the first induction cable. The second end of the first induction cable is connected with the first end ofthe second induction cable. The second end of the second induction cable is connected with the negative electrode of the power supply. A first voltage measurement device is connected in parallel withthe first induction cable. When the first induction cable and the second induction cable in the battery pack are shorted by the water drops leaking into the battery pack, the processor can judge thesituation of water leakage and the position of water leakage according to the change of the voltage value measured by the first voltage measurement device so that the maintenance personnel are enabledto rapidly and accurately clean the water drops and eliminate short circuit of the battery pack and other electrical fault.

Description

technical field [0001] The invention relates to the field of batteries, in particular to a water leakage sensing device, a battery pack and an electric vehicle. Background technique [0002] Due to the harsh working conditions of the vehicle, water may enter the battery pack of the electric vehicle when passing through a wading section. Additionally, vehicles operating in areas of high humidity face the risk of interior condensation. Water droplets inside the battery pack may cause a short circuit, which may lead to battery fire, explosion and other dangers. Contents of the invention [0003] The invention provides a water leakage sensing device, a battery pack and an electric vehicle aiming at the electrical risks that may be caused by internal water leakage of the battery pack. [0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: a water leakage sensing device, including: a processor, a water leakage se...
