Engineers have gone through great lengths to ensure the battery and drive unit of the 2017 Chevrolet Bolt EV create a fun to drive experience, while setting a benchmark in affordable, long-range EVs.
The driving experience begins with a single high capacity electric motor to propel the car. This is very much like many other electric vehicles currently available. But a powerful and quiet motor design, gearing configuration and shift-by-wire technology help set the 2017 Bolt EV apart.
In the end, the system is capable of producing 200 hp, 260 lb-ft of torque and at least 200 miles of pure electric driving. Combined with a 7.05:1 final drive ratio, it helps propel the Bolt EV from 0-60 mph in less than seven seconds.
Chevrolet and, more specifically, General Motors, worked heavily with LG Chem to develop a new generation of battery technology for the 2017 Bolt EV. Preliminary specifications for the battery system 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
In order to keep things cool, the batter system uses active thermal conditioning, similar to the Chevrolet Volt, which Chevrolet says will help maximize overall battery life.
The new cell design houses nickel-rich lithium-ion, which provides improved thermal operating performance over other chemistries, and requires a smaller active cooling system for more efficient packaging.
The 2017 Bolt EV also really helps pioneer one-pedal driving by allowing regenerative braking to become more than a tool to boost range. Through a combination of increased regenerative deceleration and special software controls, one-pedal driving allows the 2017 Bolt EV to come to a complete stop without touching the brake pedal.
When operating the Bolt EV in “Low” mode, or by holding the Regen on Demand paddle located on the back of the steering wheel, deceleration will be intense enough to bring the car to a stop.
We’ve said it once before, and we will say it again, the 2017 Chevrolet Bolt EV houses the design and technology to have a real shot at becoming the mass-market statement Chevrolet wants this car to be.
