An electric vehicle is a vehicle that uses one or more electric motors for propulsion. It can be powered by a collector system, with electricity from extravehicular sources, or it can be powered autonomously by a battery (sometimes charged by solar panels, or by converting fuel to electricity using fuel cells or a generator). In electrical machines, either input or output or both can be electricity.

Types of Electrical Machines

The electric machines are of three main types, transformer, generator, and motor.

 Most electric vehicles use lithium-ion batteries.

Types of Electric Car Lithium Battery:

• LFP (Lithium Iron Phosphate) &
• 2- LMO (Lithium Manganese Oxide)

 Lithium ion batteries have higher energy density, longer life span and higher power density than most other practical batteries [1]. The lithium contained in the batteries is a highly reactive alkali metal. If it comes into contact with water due to damage to the battery housing, a chemical reaction with very high temperatures and flash flames will be triggered – this may be familiar to you from chemistry lessons at school. It’s almost impossible to fight a fire of this kind with conventional means like extinguishing foam [4]. The lithium-ion battery has established itself as the technology of reference in the world of electric cars.

Hazard of Electrical Cars Fired:

Lithium batteries are made of chemical salts, hydrogen, phosphate, etc.

Fire and explosion of lithium batteries produce highly destructive and toxic HF gas. Other chemicals are also released. That is why it is so important to keep electric vehicles safe.

The lithium contained in the batteries is a highly reactive alkali metal. It’s almost impossible to fight a fire of this kind with conventional means like extinguishing foam. If you’re using water to put it out, you will need significantly larger quantities than you would with a petrol or diesel vehicle. What’s more, this chemical-physical reaction takes a relatively long time to play out. In other words, a damaged battery can catch fire again or at a later date. After a very serious accident, the entire vehicle must if possible be put in a container, completely covered with sand or water and placed under observation. It goes without saying that you can’t set up a container of this kind at the edge of a wood or in an enclosed space.
