Discover Electric Car Batteries.

Electric car batteries are rechargeable batteries that power electric cars, bikes, and scooters.

They are designed to give power over a sustained period and are deep-cycle batteries.

Lithium-ion batteries are usually used in EVs.

Whereas internal combustion engine cars obtain energy from gasoline or diesel combustion, an electric vehicle draws power directly from a large battery pack.

Brendan:

Discover Electric Car Batteries.

Brendan:

Electric car batteries are rechargeable batteries that power

Brendan:

electric cars, bikes, and scooters.

Brendan:

They are specifically designed to give power over a sustained period

Brendan:

and are deep cycle batteries.

Brendan:

Lithium-ion batteries are usually used in EVs.

Brendan:

How Does an Electric Car Battery Function?

Brendan:

Whereas internal combustion engine cars obtain their energy from

Brendan:

gasoline or diesel combustion, an electric vehicle draws power

Brendan:

directly from a large battery pack.

Brendan:

These are similar to a larger version of the lithium ion battery in your phone.

Brendan:

EVs don't use a single battery like a phone but rather a pack

Brendan:

made up of thousands of individual Li-ion cells that work together.

Brendan:

The Technology Used in Electric Car Batteries.

Brendan:

Electric car batteries go through cycles of discharge while driving and

Brendan:

charge when the car is plugged in.

Brendan:

The amount of charge electric car batteries can hold decreases as

Brendan:

this process is repeated over time.

Brendan:

This reduces the range and time required between charging journeys.

Brendan:

The majority of battery manufacturers provide a five to eight year

Brendan:

warranty on their products.

Brendan:

The connection between a battery and the car's electric

Brendan:

motor is surprisingly simple.

Brendan:

The battery connects to one or more electric motors, which drive the wheels.

Brendan:

When you press the accelerator, the car immediately supplies, power to

Brendan:

the motor, gradually absorbing the energy stored in the batteries...

Brendan:

... because electric motors also function as generators.

Brendan:

When you take your foot off the accelerator, the car begins to

Brendan:

slow down by converting its forward motion back into electricity.

Brendan:

This occurs more strongly if you apply the brakes.

Brendan:

Electric Car Batteries - The Lithium-ion Battery.

Brendan:

Lithium ion batteries are lightweight, high capacity batteries commonly used

Brendan:

in electronic devices, such as laptops, mobile phones, cameras, video game

Brendan:

consoles, GPS receivers, digital music players, and electric cars and bikes.

Brendan:

These batteries have a high energy density.

Brendan:

This means that battery manufacturers will be able to save space, but increasing

Brendan:

the overall size of a battery pack.

Brendan:

Use of Boron and Lithium-ion Batteries.

Brendan:

Lithium-ion batteries are used in portable electronics.

Brendan:

These batteries rely on graphite as an anode material due to its low

Brendan:

cost and good properties such as high electrical, conductivity and stability.

Brendan:

One of the primary challenges of improving lithium-ion batteries.

Brendan:

Is producing a highly ordered crystalline graphite structure through

Brendan:

high temperature, heat treatment.

Brendan:

Which requires temperatures in the 3000 degrees centigrade range.

Brendan:

Still this process can be expensive and energy intensive.

Brendan:

For increasing crystallinity, boron is incorporated into the

Brendan:

crystalline structure of graphite at higher temperatures that

Brendan:

activate greater alignment and change the electronic structure.

Brendan:

Recycling Electric Car Batteries.

Brendan:

Although enabling a second life application can extend battery life.

Brendan:

Electric car batteries must eventually be recycled.

Brendan:

In many countries.

Brendan:

BEV technologies lack a well-established recycling framework, making

Brendan:

these BEVs and other battery powered electrical equipment, a

Brendan:

considerable energy expenditure, ultimately increasing CO2 emissions.

Brendan:

The cathode materials must be crushed to remove the current collector

Brendan:

for the hydrometallurgical process.

Brendan:

The cathode materials are then leached by aqueous solutions to extract

Brendan:

the desired materials from them.

Brendan:

Are Electric Car Batteries Safer?

Brendan:

Manufacturers of electric car batteries ensure that Evie batteries are safe,

Brendan:

installing smart management systems to prevent overheating and other issues.

Brendan:

Batteries do get warm during charging and discharging, but cars

Brendan:

are designed to keep them cool.

Brendan:

High-performance EVs may have liquid cooling systems to assist.

Brendan:

In response to the incident, which resulted in a minor fire.

Brendan:

Tesla CEO, Elon Musk, stated that electric car batteries contain only

Brendan:

about a 10th of the energy of a tank full of fuel, reducing the danger.

Brendan:

And that's all for today on the topic of electric cars, batteries, and safety.

Brendan:
