The idea of a car shedding its battery when it's about to catch fire

Toot, toot, toot, toot, toot, toot, toot, toot! Fire risk! Prepare to disengage the battery! 321, complete separation. The vehicle glides 10 meters before stopping, and the occupants of the vehicle get off to report the fire, and put out the fire according to the situation. This is the "removable battery" in the car running battery is about to catch fire scenario application.

According to the Fire and Rescue Bureau of the National Emergency Management Administration, there were 640 neV fires in China in the first quarter of 2022, up 32 percent from the same period last year, and an average of more than seven neV fires a day, an alarming figure.

Until the current battery technology breaks through, we may need to find a backstop to keep drivers and passengers safe. A new energy vehicle fire warning when the battery off the idea of the idea emerged.

When the new energy vehicle is in the process of moving, the battery management system monitors the rapid rise of the battery temperature and is about to reach the fire temperature, the detachment device is immediately started to pop the battery fixed at the bottom of the chassis directly from the chassis, so that it is separated from the body, so that the fire source risk away from the car.

To further enhance safety, measures such as ensuring the safety of other vehicles on the road and designing fire-retardant materials in the battery cover need to be considered.

The idea of a car shedding its battery when it's about to catch fireAnother scenario is that there is a risk of battery fire when the new energy vehicle is charging or stopping. At this time, the action of disconnecting from the battery can also be started. At the same time, automatic movement device needs to be configured on the battery to keep away from the body and other cars, which requires a more in-depth design scheme.

For now, the idea is more suitable for those with battery packs fixed to the chassis of the vehicle. When there is a fire risk of the vehicle battery, the battery pops out and falls vertically to the ground, which can minimize the occurrence of secondary disasters.

The scheme is not mature and only provides an emergency action for the car when the battery is about to catch fire, and there are many situations that are not taken into account. Therefore, it can only be used as a reference for new energy vehicles to avoid the risk of battery fire. Improving battery safety ultimately requires innovation in battery technology, as well as active research and development of new materials and technologies by major new energy vehicle and battery factories.
