The Bolt EV benefits directly from the suggestions and ideas of Volt owners and features technologies that make owning a long-range electric vehicle easy.

The Bolt EV's connectivity innovations will provide smart, personalized solutions for managing the driving experience. For example, in the future an accurate driving range projection will be based on the time of day, typography, weather and the owner's driving habits.



Many of the Bolt EV's driver-focused technologies are supported by OnStar 4G LTE, which turns the Bolt EV into a Wi-Fi hotspot, giving owners easier access to apps and services via a high-speed wireless connection.

Other connectivity and infotainment features include:
◾10.2'' MyLink color touch-screen display
◾Customizable, widget-based 'flip-board style' operation

◾Rear Camera Mirror
◾Rear-facing camera provides a wide-angle view of the environment behind the vehicle.

◾Surround Vision
◾Provides a bird's-eye view of what's around the Bolt EV for improved safety during low-speed driving and when parking.

◾All-New MyChevrolet Mobile App: Combines important owner and vehicle information and functions, such as:
◾Vehicle charge status
◾OnStar Map service
◾Remote start
◾Cabin pre-conditioning
◾Owner's manual information
◾Dealer service scheduling

◾EV Navigation Mapping
◾EV-specific navigation capability that designs routes to maximize range and provide locations of nearby charging station locations if needed.

◾Gamification
◾In the future, Bolt EV owners will be able to 'compete' by comparing driving styles to determine who is driving most efficiently.

The Bolt EV will be built at GM's Orion (Mich.) Assembly facility, near Detroit.

DRIVE UNIT AND BATTERY AT THE HEART OF CHEVROLET BOLT EV

DETROIT – The 2017 Chevrolet Bolt EV does more than set a new benchmark for affordable, long-range EV driving. It also raises the bar when it comes to driving performance.
Engineers developed the Bolt EV's propulsion system to offer more than an estimated 200 miles (based on GM estimates) and a delightful driving experience that's more akin to a compact sports sedan than a small utilitarian crossover.




Single Motor Drive Únit
Like most EVs on the road, the Bolt EV's drive system uses a single high capacity electric motor to propel the car. But it's the smooth, powerful and quiet motor design, gear configuration and shift-by-wire system that separates it from the pack.

The engineering team designed the Bolt EV's electric motor with an offset gear and shaft configuration tailored to meet efficiency and performance targets – most notably more than an estimated 200 miles of range. The motor is capable of producing up to 266 lb.-ft. (360 Nm) of torque and 200 hp (150 kW) of motoring power. Combined with a 7.05:1 final drive ratio, it helps propel the Bolt EV from 0-60 mph in less than seven seconds.



60 kWh Battery System
Having more than 1.3 billion miles of EV experience from the Chevrolet Volt helped Bolt EV battery engineers and strategic partner LG Electronics to develop an all-new cell and battery pack to offer more than an estimated 200 miles of range.

Battery system preliminary specifications include:
◾60 kWh lithium-ion battery pack.
◾288 lithium ion cells◾Five sections
◾10 modules
◾96 cell groups – three cells per group

◾960 lbs. (435 kg) total weight

'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 battery uses active thermal conditioning, similar to the Chevrolet Volt, to keep the battery operating at its optimum temperature, which results in solid battery life performance. The Bolt EV battery will be covered by an 8-year/ 100,000 mile (whichever comes first) limited warranty.

Inside the battery pack – which spans the entire floor, from the front foot well to back of the rear seat – is a new cell design and chemistry. The nickel-rich lithium-ion chemistry provides improved thermal operating performance over other chemistries, which requires a smaller active cooling system for more efficient packaging. The chemistry allows the Bolt EV to maintain peak performance in varying climates and driver demands.

The cells are arranged in a 'landscape' format and each measures in at only 3.9 ins. (100 mms) high and 13.1 ins. (338 mms) wide providing improved packaging underfloor. The lower profile cell design enabled the vehicle structure team to maximize interior space.

The battery system is mated to a standard equipment 7.2 kW onboard charger for regular overnight charging from a 240-V wall box. A typical commute of 50 miles can be recharged in less than two hours. Bolt EV also features an optional DC Fast Charging system using the industry standard SAE Combo connector. Úsing DC Fast Charging, the Bolt EV battery can be charged up to 90 miles of range in 30 minutes. Outside temperatures may affect charging times.

Regen System Provides One-Pedal Driving
Regenerative braking has become more than just a tool to boost range, it's also transformed into a feature that can provide an improved EV driving experience. The Bolt EV features a new regenerative braking system that has the ability to provide one pedal driving.

'Interviews with EV enthusiasts indicated their desire for one pedal driving capability on the Bolt EV. One pedal operation boosts the thrill and uniqueness of EV driving,' Tavel §äid.

Through a combination of increased regenerative deceleration and software controls, one pedal driving enables the vehicle to slow down and come to a complete stop without using the brake pedal in certain driving conditions.

When operating the Bolt EV in 'Low' mode, or by holding the Regen on Demand paddle located on the back of the steering wheel, the driver can bring the vehicle to a complete stop under most circumstances by simply lifting their foot off the accelerator, although the system does not relieve the need to use the brake pedal altogether.

Operating the Bolt EV in 'Drive' mode and not pulling the paddle while decelerating delivers a driving experience where usage of the brake pedal is required to stop.
