Concept

Echo Car Challenge

"...It was called the Echo Car Challenge. Right, right, right, right. So they said, you know, we want to sponsor a handful of universities in the country..."

The Echo Car Challenge was a contest where teams from universities were asked to create new ideas for car engines and power systems that use energy more efficiently. It was about thinking outside the box and coming up with new solutions.

Term

battery pack

"Like, what did a Model 3 Model Y battery pack weigh?"

A battery pack is like a big container of batteries that gives power to electric cars. It stores electricity so the car can run without using gas.

Term

powertrain

"...you had to put a design of your proposed power train in there, run simulations about how it would perform, have a business case. What was your proposed power train?"

The powertrain is what makes a car move. It includes the engine and other parts that help transfer power to the wheels.

Term

hybrid vehicles

"...At the time it was for hybrid vehicles, there are different types of series and parallel hybrids."

A hybrid vehicle is a car that uses both a traditional engine and an electric motor to run. This helps save fuel and is better for the environment.

Term

series and parallel hybrids

"...there are different types of series and parallel hybrids. There are ways to actually combine them and more of a power split hybrid."

In series hybrids, the gas engine only makes electricity for the electric motor. In parallel hybrids, both the gas engine and electric motor can work together to move the car.

Term

continuously variable transmission

"Some of the early Prius's did that, but they use more of a continuously variable transmission. There are ways to combine that, but also having discrete gear ratios in it."

A continuously variable transmission is a type of automatic transmission that can adjust to any gear ratio, making it smoother and often more fuel-efficient than regular automatic transmissions that have set gears.

Term

discrete gear ratios

"There are ways to combine that, but also having discrete gear ratios in it. So discrete gear ratios can have a much higher transmission efficiency, but the CVT mode..."

Discrete gear ratios are fixed settings in a car's transmission that determine how fast the car can go at a given engine speed. They can help the car run more efficiently in some situations.

Term

BSFC map

"...but the CVT mode, you can essentially keep the engine right in the sweet spot of that BSFC map. So combining the two had a lot of synergies to it."

A BSFC map shows how efficiently an engine uses fuel to produce power. It helps engineers find the best way to make an engine run smoothly and use less fuel.

Term

capacitors

"And like race cars nowadays where it's big capacitors and fast in, fast out."

Capacitors are devices that can store electricity and release it very quickly. In race cars, they help give a quick boost of power when needed without relying on a big battery.

Term

power-to-energy ratio

"Yeah, and even with the batteries, a lot of different chemistries, you can vary the power to energy ratio. So relatively small battery, high power, and then the combustion engine, I wanted a really high biofuel waiting."

This term describes how much power a battery can give compared to how much energy it holds. A higher number means the battery can give a lot of power quickly, which is useful for things like racing.

Term

E85

"...high ethanol, E85, kind of it was one on the market at the time. Lower volume metric energy efficiency, but actually quite a bit higher thermal efficiency..."

E85 is a type of fuel made mostly from ethanol, which is a plant-based alcohol. It can help cars run better because it has a higher octane level than regular gas.

Term

high compression ratio engine

"...much higher percentage of Carnot with that high compression ratio engine. So kind of combine all that into a design..."

This type of engine squeezes the fuel and air mixture a lot, which helps it produce more power and be more efficient. It needs special fuel to work well without making noise that can damage the engine.

Car

Chevrolet Volt

"That was when the Chevy, the Volt was on the road, but kind of going through a lot of redesigns."

The Chevrolet Volt is a car that can run on electricity and gasoline. This means you can drive it using just electric power for short trips, and if you need to go further, the gasoline engine kicks in to help.

Car

Tesla Model S

"...the time Tesla was trying to scale up the Model S"

The Tesla Model S is a high-end electric car that can go long distances on a single charge. It's known for being fast and having a lot of technology features.

Car

Tesla Model 3

"I've been to the factory. I went there for when Model 3 came out. And from the front, you couldn't see a..."

The Tesla Model 3 is a type of electric car that runs on batteries instead of gasoline. It's popular because it's cheaper than many other electric cars and can go a long distance on a single charge.

Car

Cadillac Escalade

"... in Detroit and it would eventually end up in an Escalade or a Hummer? Is that accurate?"

The Cadillac Escalade is a big, fancy SUV that has a lot of space inside and comes with lots of luxury features. People often buy it because it's seen as a status symbol and is very comfortable to drive.

Term

second life battery

"...They put the second life leaf battery solar system in their parking lot, meaning they're taking batteries..."

A second life battery is a battery that has been used before, like in an electric car, and is now being used again for something else, such as storing energy from solar panels.

Car

Nissan Leaf

"...Nissan just put in their Nashville headquarters. They put the second life leaf battery solar system in their parking lot..."

The Nissan Leaf is a popular electric car that runs on batteries instead of gasoline. It's known for being environmentally friendly and is often used for daily commuting.

Term

solar panels

"...putting them in the ground, and storage batteries for the solar panels above the parking structure."

Solar panels are special panels that catch sunlight and turn it into electricity. They help provide power for homes and buildings, especially when combined with batteries for storage.

Car

Ford Cortina

"Ryan, we first profiled him. Our man Miguel Cortina did some hunting around and you appeared near the..."

The Ford Cortina is a small car that was made a long time ago and was very popular in Europe. It was known for being affordable and practical for everyday use.

Car

Tesla Model Y

"Tons of weight, right? Like, what did a Model 3 Model Y battery pack weigh? 1,500 pounds?"

The Tesla Model Y is an electric SUV, which means it's a bigger car than the Model 3 and can hold more people and stuff. It's becoming popular because many people like the idea of driving an electric car that also has more room.
