The new Chevy is propelled by a single high capacity electric engine, just like most EVs out there. What makes this car special is the electric motor design, gear configuration and shift-by-wire system. The engine produces 200 horsepower and 266 lb.-ft of torque that propel the car from 0 to 60 mph in seven seconds.

Power delivery is controlled by Chevrolet’s first Electronic Precision Shift System that sends electronic signals to the car’s drive unit to make use of the power and torque depending on drive mode selection and accelerator inputs.

According to Josh Tavel, Chevrolet Bolt EV chief engineer, “Being the leader in range and affordability means nothing if the car isn’t going to excite you each time you get behind the wheel. That’s why the team was tasked with delivering a propulsion system that would also make the Bolt EV an electric vehicle that owners would love to drive.

Based on a vast EV experience, the American company’s engineers together with those from LG Electronics managed to develop an all-new cell and battery pack that increases the range to an estimated 200 miles. The battery system includes a 60 kWh battery pack, 288 lithium ion cells divided into five sections, ten modules, and 96 cell groups, weighs 960 lbs and spans the entire floor.

As a lot of heat is produced, the batteries keep the temperature under control by using active thermal conditioning, which results in solid battery life performance. The company gives an 8-year or 100,000-mile limited warranty for Bolt’s battery pack.

Each cell measures only 3.9 inches high and 13.1 inches wide and are arranged in a “landscape” format. The lower profile cell design allowed the team to develop a bigger interior space.

You usually have a battery cell that delivers either the desired levels of energy or power, but not traditionally both. With this cell design and chemistry we were able to deliver a battery system with 160 kilowatts of peak power and 60 kilowatts hours of energy, ” said Gregory Smith, Bolt EV battery pack engineering group manager.

The car can be charged from a 240-V wall box thanks to its standard 7.2 kW onboard charger. Thanks to the optional DC Fast Charging System, the Bolt EV can be charged up to 90 miles of range in just 30 minutes, depending on the outside temperature.

The new Chevy Bolt EV features a new regenerative braking system that is more than just a tool to boost range and has the ability to provide one pedal driving, which enables the car to slow down and come to a complete stop without using the brake pedal in certain drive conditions.

When traveling in Low mode or by holding the Regen on Demand paddle located behind the steering wheel, the driver can bring the car to a complete standstill only by lifting his foot off the accelerator. If the car is running in Drive mode, and the paddle is not pulled while decelerating, the brake pedal must be pressed for the car to stop.

This system was introduced after the company conducted several interviews with EV enthusiasts who expressed their desire for one pedal capability on the Bolt EV.
