Fiat and Chrysler unveil battery-electric 500e

Chrysler in Auburn Hills did a commendable job of the 500e’s electric propulsion in the diminutive A-class hatchback.

New and rear fascias, road rear spoiler, underbody and other aerodynamic improvements in 24 counts of drag reduced on the compared with the conventional Claimed Cd is .311. But the car gained 600 lb (272 kg) compared with the non-EV model.

The 500e’s cluster contains simple, eco-driving coaching and vehicle-feedback

Chrysler has lagged most of the in bringing electrified vehicles to but the 2014 Fiat 500e, unveiled Nov. 28 at the 2012 Auto Show, is a big step getting the automaker into the

Unlike the rest of the growing 500 that is based on Fiat’s Mini platform, the battery-electric Group’s first production developed by Chief Engineer Giem’s American engineering based at Chrysler’s Auburn MI, tech center.

“The 500e is not for electric-vehicle said Tim Kuniskis, Head of Marketing for North America. we are positioning it for Fiat 500 owners who to try a new technology.” The vehicle will be in Toluca, Mexico, and launched in California.

The A-segment EV is claimed by to deliver an estimated 116 mpg-e per gallon equivalent) city and 100 highway electric-drive efficiency, more than 80 mi (129 km) per charge. The U.S. EPA is currently Chrysler data as part of the rating process. Chrysler is the 500e will accelerate 0-60 mph (0-97 km/h) in than 9 s.

Battery details

The electric propulsion system a 24-kW·h NiMgCo lithium-ion sourced from SB LiMotive. the — Samsung partnership. The pack is comprised of 97 cells. It is cooled to ensure robust performance in all markets and to help the car’s +80-mi range, explained.

Chrysler will the battery pack for eight

Driving the car’s front is an 83-kW permanent-magnet motor and final drive that has named “e-Drive.” The 3-phase electric machine generates 147 (200 N·m). According to the system has 45 kW of total regenerative Chrysler engineers developed the fully blended regen control strategy and included a function to better acclimate customers who are used to the low-speed of torque-converter-equipped automatic transmissions.

The system is engineered with an power module, which the battery’s high-voltage output to 12 V to the standard vehicle electrical

There are two cooling system for the battery pack and one for the passenger The battery thermal-management system, in to maintaining optimal operating for the high-voltage system, also supplemental passive cooling. the car’s brazed aluminum the system is configured to remove from the ethylene glycol-based as air enters the front of the vehicle.

The also provides cooling for the eDrive motor and the power

There is a high-voltage heating for the interior. Giem said can expect a 10% reduction of driving on a cold day with the cabin turned on. The vehicle features battery preconditioning capability a smart-phone app.

Architected for J1772 quick-charge

The program was launched in 2010. An fleet of 40 mules grew to the 100-car test fleet. The was virtually in parallel to SAE International ’s of the revised J1772 standard for EVs and PHEVs (go to to read on the updated standard).

The revision dc charging (previously known as 3) in addition to ac Levels 1 and 2 and features the new connector” hardware that believe will dramatically charging time for vehicles so

“The car is technically and architecturally for the new SAE J1772 Level 3 quick but we just timed out on the first-phase so we’re using Level 2 V] hardware at launch,” Giem AEI . He said upgrading the car to quick-charge to be compatible with the new SAE combo will mainly require of the right rear quarter to provide a larger charge-coupler and access door. The current door is a carryover from the 500 and doesn’t provide enough to fit the female charge connector or access clearance for the larger combo connector.

The high-voltage battery is hard-mounted to the structure and located longitudinally in the along the 500e’s centerline. The is considered a structural member and a 10% increase in bending stiffness, to Giem. The packaging of the propulsion is remarkable, given the diminutive

Giem’s team was careful not to let the intrude into the 500’s which has a special cubby for the cord. The rear passenger already a tight squeeze on the 500, are raised about 100 mm (4 in) to the battery pack underneath.

617 lb mass, reducing NVH

Chrysler engineers put a lot of work the 500e’s aerodynamics, which are a challenge on A-segment vehicles. front and rear fascias, a efficient rear spoiler, and new aluminum road wheels, with underbody fairings, worth 48 counts of aerodynamic lowering the car’s drag to .311 Cd vs. 359 Cd on the conventional 500.

with low rolling resistance designed specifically for the 500e.

the 500 brought a 617-lb (280-kg) weight penalty vs. the base The 500e weighs 2950 lb kg), and the car’s front-to-rear balance has shifted to a more bias: 57/43%, compared to on the conventional 500.

Chassis and engineers designed the 500e’s specifically for the additional mass, a focus on retaining the 500’s qualities. Spring rates are and the tuning of the front struts and shocks is unique to the EV. Calibration of the power steering also is to the 500e, which features a steering-gear ratio for improved according to Giem.

Eliminating the combustion engine put a new on improving the 500’s NVH characteristics. In to the major aero improvements, team executed 12 product-specific aimed at reducing cabin They include new acoustic glass; additional mastic and sound-deadening material on the floor doors, rear quarter and in the wheelhouses; thicker carpet and an additional 8 mm (0.31 in)-thick pad installed in the rear floor
