How did a water intrusion affect EVs?

The water intrusion left water marks, debris, sediment, and mold/mildew on the seats, sills, floor, and instrument panel. The high voltage battery casings were exclusively located underneath the EVs. The high voltage battery casings of all the EVs were fully submersed:

Are EV batteries waterproof?

For example, the battery pack is often located in the vehicle’s undercarriage, which helps shield it from splashes and minor floods. Additionally, many EV batteries have a waterproof casing that provides a barrier against water intrusion. Despite the protective measures, water exposure can still pose a risk to EV batteries.

Can EV batteries come into contact with water?

EV lithium batteries are not supposed to come into contact with water, as this can cause serious damage to the battery and create safety hazards for the occupants. When water comes into contact with lithium-ion batteries, it can cause a chemical reaction that produces flammable gases, leading to the battery catching fire or exploding.

Does water damage EV batteries?

Despite the protective measures, water exposure can still pose a risk to EV batteries. When water comes into contact with the battery’s electrical components, it can cause corrosion, short circuits, and potentially damage performance.

What is the EV battery connection system?

Inside the pack, the EV battery cell connection system combines individual cells in parallel and series configuration to create both energy and power for the pack, as well as providing critical sensor data to the Battery Management System (BMS) to control the pack functions.

What is a pack battery management system?

The pack Battery Management System monitors voltage, current, and temperature of cells Sensors that should be considered within the EV battery pack design and module assembly systems: 1. Temperature Temperature sensors are critical for electric vehicle battery and cell connection system applications.
