As we shift gears towards a more electric future, the question of electric vehicle safety takes on new dimensions. Are electric vehicles as safe as their traditional counterparts? And what are the roadblocks to their widespread safety in our future world?

Electric vehicles (EVs) are no longer a fringe concept of the future; they're the wheels of the present, rolling out into our roads with increasing frequency.

From the sleek Tesla Model S to the pragmatic Nissan Leaf, electric vehicles have captured the imagination of environmentally conscious consumers and industry innovators alike.

In this article, we'll strip down the electrical phenomenon to its bare metal and lithium-ion batteries, scrutinizing EV safety from various angles.

How do Electric Vehicles work?

To understand the safety concerns surrounding electric vehicles, it's important to first understand how they work.

Electric vehicles are powered by one or more high voltage electrical systems that use electricity stored in batteries for energy. These motors provide power to move the vehicle and its components such as lights, heating and air conditioning systems.

The primary source of energy for an electric car is a rechargeable lithium ion battery pack. The battery pack is charged by plugging the vehicle into an electric power source, usually a charging station or outlet.

What are high voltage Electrical systems?

High voltage electrical systems in an EV refer to the powertrain, which includes the battery, motor, and inverter. These components work together to propel the vehicle forward.

The battery pack is the heart of an EV, storing energy for use by the motor. It is made up of many individual cells connected together to form a larger unit. The motor then receives power from the battery and converts it into mechanical energy to turn the wheels.

The inverter is responsible for converting direct current (DC) from the battery into alternating current (AC) that powers the motor. This allows for more efficient use of the battery's energy.
