Just as Chrysler revealed at the Detroit Auto Show earlier this year, the company introduced three new Battery Electric Vehicle (BEV) Prototypes not based on what they had shown previously. Well sort of…
Auburn Hills, MI- Chrysler announced a new production-intent, advanced electric-drive technology packaged in three different vehicles – one for each of its brands, Chrysler, Jeepฎ and Dodge.
Chrysler will select one electric-drive model to be produced in 2010 for consumers in North American and European markets after 2010.
The Company said that it is well into the development of battery electric vehicles, and that it will apply electric-drive technology to its front-wheel-drive, rear-wheel-drive and body-on-frame four-wheel-drive platforms in the next several years.
Shown today, the Dodge EV, Jeep EV and Chrysler EV including a demonstration of driving performance and capability.
“We have a social responsibility to our consumers to deliver environmentally friendly, fuel-efficient, advanced electric vehicles, and our intention is to meet that responsibility quickly and more broadly than any other automobile manufacturer,” said Bob Nardelli, Chairman and CEO – Chrysler LLC. “The introduction of the Chrysler, Jeep and Dodge electric vehicles provides a glimpse of the very near future, and demonstrates that we are serious and well along in the development of bringing electric vehicles to market.”
ENVI Organization
“ENVI was created just over one year ago with the strategic intent to develop electric-drive vehicles quickly for Chrysler, and it is surpassing expectations,” said Tom LaSorda, Vice Chairman and President – Chrysler LLC. “With ENVI, Chrysler is developing technology to bring Electric Vehicles and extremely fuel-efficient Range-extended Electric Vehicles to market.”
Battery Electric Vehicle Technology
Chrysler’s Electric Vehicles utilize just three primary components. These include an electric motor to drive the wheels, an advanced lithium-ion battery system to power the electric-drive motor and a controller that manages energy flow. The electric-drive system is being developed for front-wheel-drive, rear-wheel-drive, and body-on-frame four-wheel-drive vehicle applications.
Along with the basic BEV description comes the pie in the sky “whistling past the graveyard” commentary…
“This technology provides customers with a vehicle that has zero tailpipe emissions and a 150- to 200-mile driving range – far exceeding most Americans’ daily commutes, as nearly 80 percent of Americans drive less than 40 miles per day, or 14,000 miles per year,” said Frank Klegon, Executive Vice President – Product Development, Chrysler LLC. “Electric Vehicles provide the opportunity to fulfill social responsibility, reduce dependency on foreign oil, and eliminate monthly gasoline bills, while delivering performance and utility that our customers desire.”
Range-extended Battery Electric Vehicle (PHEV) Technology
Just like the Chevrolet Volt’s EREV, the Range-extended PHEV combines the electric-drive components of the BEV with a small gasoline engine and integrated electric generator to produce additional energy to power the electric-drive system when needed. This provides the energy efficiency of a BEV with the driving range equivalent to today’s gasoline-powered vehicles.
Dodge EV
The Dodge EV development BEV is a Viper based rear-wheel-drive sports car that marries high performance with zero tailpipe emissions.
“The Dodge EV sets a new standard for what can be expected in electric-drive vehicles,” said Lou Rhodes, Vice President – Advance Vehicle Engineering, and President – ENVI. “The electric-vehicle technology enables a fun-to-drive performance sports car and helps redefine the vision of an environmentally responsible vehicle for the Dodge brand.”
The electric-drive system consists of three primary components: a 200 kW (268 horsepower) electric motor, an advanced Li-ion battery and an integrated power controller.
The 200 kW electric-drive motor generates 480 lb.-ft. of torque. The instant high torque of the electric-drive motor delivers outstanding performance, accelerating the Dodge EV to 60 mph in less than five seconds, with quarter-mile times of 13 seconds. The Dodge EV has a top speed of more than 120 mph.
Working with the latest advanced Li-Ion battery technology, the Dodge EV has a continuous driving range of 150 plus miles – more than triple the average daily commute of most consumers. Recharging the vehicle is a simple one-step process: plugging into a standard 110-volt household outlet for eight hours. The recharge time can be cut in half to four hours by using a typical 220-volt household appliance power outlet.
The Dodge EV offers driving enthusiasts a performance sports car that can be driven to work every day – without consuming gasoline or producing tailpipe emissions.
Jeep EV
The Jeep PHEV development vehicle is a PHEV that provides a glimpse into the future of a “Go Anywhere, Do Anything” vehicle with renowned Jeep Wrangler capability.
The Jeep PHEV combines Wrangler’s unmatched off-road capability with the ultimate “Tread Lightly” mindset by providing nature ambassadors with the ability to roam the planet and take care of it at the same time.
The Jeep PHEV uses an electric motor, an advanced Li-Ion battery system, and a small gasoline engine with an integrated electric generator to produce additional energy to power the electric-drive system when needed. The 268 HP electric motor generates 295 lb.-ft. of torque. With approximately eight gallons of gasoline, the Jeep EV has a range of 400 miles, including 40 miles of zero fuel-consumption, zero-emissions, all-electric operation.
“We are also exploring four-wheel-drive, in-wheel electric motors to demonstrate the full reach of ENVI’s advanced electric-drive technologies,” said Rhodes.
The instant high torque of the electric-drive motor and the ability to precisely control each wheel independently results in off-road capability ideally suited for the Jeep brand, without compromising on-road driving capability.
Chrysler EV
The Chrysler EV development vehicle is a Chrysler Minivan modified as a PHEV that demonstrates another possible application of ENVI electric-drive technology in the segment-leading Chrysler Town & Country minivan.
“With the Chrysler EV, we are able to blend seven-passenger capability and the luxury of the Chrysler Town & Country minivan with electric-drive technology, demonstrating family practicality with zero compromise,” said Rhodes. “ENVI’s electric-drive development vehicles showcase our accelerated application of electric-drive systems into a wide range of vehicles in Chrysler’s future product portfolio.”
The Chrysler EV combines the electric-drive components of an Electric Vehicle with an integrated small-displacement engine and generator to produce additional electricity to power the electric-drive system when needed. This provides all of the positive attributes of an Electric Vehicle and extends the driving range to be equivalent to today’s gasoline-powered vehicles – without compromises.
The Chrysler EV uses a 255 HP motor, producing 258 lb.-ft. of torque, providing 0 to 60 mph acceleration in approximately nine seconds. The Chrysler PHEV can drive 40 miles on all-electric power, and boasts a range of 400 miles on approximately eight gallons of gasoline. This makes the Chrysler EV the perfect fuel-efficient family vehicle.
The knowledge and experience gained from the Chrysler EV will be applied to other front-wheel-drive applications in Chrysler’s portfolio.
Chrysler Electric-Vehicle Consumer Web Site
Chrysler LLC has launched a Web site –
Chrysler Goes Electric – to allow consumers to view the latest updates on Electric Vehicles and Range-extended Electric Vehicles from the Company. Content will include videos, photography and news, and visitors can sign up for updates. In addition, the site features a blog where consumers can interact directly with the Company.
Department of Energy Cooperative Agreement
Chrysler and General Electric are jointly pursuing a project with the United States Department of Energy to explore advanced energy-storage technology.
“Chrysler’s partnership with General Electric combines the electric-drive technology demonstrated in the Chrysler Electric Vehicles, with GE’s research and development of advanced energy storage systems,” said Klegon. “Our collective goal working with the DOE is to develop a new, integrated energy-storage system to make electric vehicle battery packs smaller and significantly less expensive than current designs.”
Chrysler and GE will develop and evaluate dual-battery solutions based on GE’s unique technology.
“One of the challenges with electric vehicles is finding a battery with the correct balance between power – for example, during vehicle acceleration – and energy for long driving range,” said Klegon. “We believe that combining two unique battery chemistries – one biased toward power and the other toward energy – into a single battery pack is very promising for a future Chrysler Electric Vehicle.”
What we expect is a large SuperCap for instantaneous storage and assist for acceleration and regenerative braking while the Li-Ion provides large storage capacity and power for steady state cruising.
