What Does Insulation Fault in New Energy Vehicles Mean?

[LeEzra]

Insulation fault in new energy vehicles refers to a leakage in the electrical circuit. The following is a detailed introduction to insulation faults in electric vehicles: 1. Cause: Insulation faults occur when the electrolyte inside the battery leaks, leading to liquid seepage. When the liquid seeps to a certain extent, the insulation layer is compromised, creating a conductive circuit between the battery modules and cells, which triggers the fault warning. If there is only a single point of insulation failure in the system, it may not immediately cause noticeable effects. However, multiple points of insulation failure can result in leakage current flowing between these points, potentially leading to a fire. 2. Precautions: Operators must wear protective equipment that meets national safety standards, such as insulated gloves and insulated shoes. In the event of an insulation fault, the faulty battery pack usually needs to be replaced. If multiple insulation faults occur, the entire battery may need to be replaced.
