Drive Unit Of Measurement As Well As Battery At Middle Of Chevrolet Bolt Ev [Video]
The 2017 Chevrolet Bolt EV does to a greater extent than than gear upwards a novel 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 organization to offering to a greater extent than than an estimated 200 miles (based on GM estimates) as well as a peppy driving experience that’s to a greater extent than akin to a compact sports sedan than a small-scale utilitarian crossover.
“Being the leader inward arrive at as well as affordability agency goose egg if the machine isn’t going to excite you lot each fourth dimension you lot larn behind the wheel,” said Josh Tavel, Chevrolet Bolt EV primary engineer. “That’s why the squad was tasked alongside delivering a propulsion organization that would also brand the Bolt EV an electrical vehicle that owners would beloved to drive.”
Single Motor Drive Unit
Like virtually EVs on the road, the Bolt EV’s displace organization uses a unmarried high capacity electrical motor to propel the car. But it’s the smooth, powerful as well as serenity motor design, gear configuration as well as shift-by-wire organization that separates it from the pack.
The technology scientific discipline squad designed the Bolt EV’s electrical motor alongside an offset gear as well as shaft configuration tailored to run into efficiency as well as performance targets – virtually notably to a greater extent than than an estimated 200 miles of range. The motor is capable of producing upwards to 266 lb.-ft. (360 Nm) of torque as well as 200 hp (150 kW) of motoring power. Combined alongside a 7.05:1 lastly displace ratio, it helps propel the Bolt EV from 0-60 mph inward less than vii seconds.
Power delivery is controlled past times Chevrolet’s root Electronic Precision Shift system. This shift as well as park-by-wire organization sends electronic signals to the Bolt EV’s displace unit of measurement to grapple precise experience as well as delivery of mightiness as well as torque, based on displace manner choice as well as accelerator inputs. Influenza A virus subtype H5N1 by-wire shifter requires less packaging infinite than a traditional mechanical shifter, resulting inward to a greater extent than interior infinite as well as improved interior layout.
60 kWh Battery System
Having to a greater extent than than 1.3 billion miles of EV experience from the Chevrolet Volt helped Bolt EV battery engineers as well as strategic partner LG Electronics to railroad train an all-new jail mobile telephone as well as battery pack to offering to a greater extent than than an estimated 200 miles of range.
Battery organization preliminary specifications include:
“You unremarkably accept a battery jail mobile telephone that delivers either the desired levels of liberate energy or power, but non traditionally both. With this jail mobile telephone blueprint as well as chemical scientific discipline nosotros were able to deliver a battery organization alongside 160 kilowatts of peak mightiness as well as lx kilowatts hours of energy,” said Gregory Smith, Bolt EV battery pack technology scientific discipline grouping manager.
The battery uses active thermal conditioning, like to the Chevrolet Volt, to continue the battery operating at its optimum temperature, which results inward company battery life performance. The Bolt EV battery volition live covered past times an 8-year/ 100,000 mile (whichever comes first) express warranty.
Inside the battery pack – which spans the entire floor, from the forepart human foot good to dorsum of the raise spot – is a novel jail mobile telephone blueprint as well as chemistry. The nickel-rich lithium-ion chemical scientific discipline provides improved thermal operating performance over other chemistries, which requires a smaller active cooling organization for to a greater extent than efficient packaging. The chemical scientific discipline allows the Bolt EV to keep peak performance inward varying climates as well as driver demands.
The cells are arranged inward a “landscape” format as well as each measures inward at exclusively 3.9 ins. (100 mms) high as well as 13.1 ins. (338 mms) broad providing improved packaging underfloor. The lower profile jail mobile telephone blueprint enabled the vehicle construction squad to maximize interior space.
The battery organization is mated to a criterion equipment 7.2 kW onboard charger for regular overnight charging from a 240-V wall box. Influenza A virus subtype H5N1 typical commute of fifty miles tin live recharged inward less than ii hours. Bolt EV also features an optional DC Fast Charging organization using the manufacture criterion SAE Combo connector. Using DC Fast Charging, the Bolt EV battery tin live charged upwards to xc miles of arrive at inward xxx minutes. Outside temperatures may touching charging times.
Regen System Provides One-Pedal Driving
Regenerative braking has snuff it to a greater extent than than precisely a tool to boost range, it’s also transformed into a characteristic that tin render an improved EV driving experience. The Bolt EV features a novel regenerative braking organization that has the mightiness to render 1 pedal driving.
“Interviews alongside EV enthusiasts indicated their wish for 1 pedal driving capability on the Bolt EV. One pedal functioning boosts the thrill as well as uniqueness of EV driving,” Tavel said.
Through a combination of increased regenerative deceleration as well as software controls, 1 pedal driving enables the vehicle to deadening downwards as well as come upwards to a consummate halt without using the brake pedal inward for sure driving conditions.
When operating the Bolt EV inward “Low” mode, or past times asset the Regen on Demand paddle located on the dorsum of the steering wheel, the driver tin convey the vehicle to a consummate halt nether virtually circumstances past times precisely lifting their human foot off the accelerator, although the organization does non salve the demand to utilization the brake pedal altogether.
Operating the Bolt EV inward “Drive” manner as well as non pulling the paddle piece decelerating delivers a driving experience where usage of the brake pedal is required to stop.
