New generation of batteries for electric cars

WE might be on the verge of a breakthrough in battery technology according to this latest article in Fortune:

Imagine an electric car that could travel more than 300 miles on a single charge. A pipe dream? Yes, for now. But a Michigan startup called Sakti3 just might make it a reality. In August the company announced that it was close to achieving the holy grail of power storage: a battery with about double the energy density of today’s lithium-ion technology at one-fifth the cost. Such a battery could give us the first $25,000 mass-market electric car, with a driving range that would please most customers.

You can watch the TED talk above as well by company CEO Dr. Ann Marie Sastry.

Range anxiety is a huge issue for electric cars, so new battery technology that extends the range for electric vehicles can be a game changer in the electric car consumer market. The innovation here is a solid-state lithium-ion battery. They expect the technology to be commercialized within a year or two. Let’s see if they achieve that goal.

  

Review of 2014 Nissan Pathfinder Hybrid

2014 Nissan Pathfinder Hybrid Offers 26 MPG Combined Fuel Econom

The stereotype of hybrid cars is slowly becoming obsolete as more vehicles are offered with hybrid options. With the 2014 Nissan Pathfinder Hybrid, consumers can now purchase a full-sized CUV with real towing capacity while enjoying the improved gas mileage offered by hybrid vehicles. Sure, you won’t approach the MPG numbers of smaller hybrid vehicles, but you’ll you’ll have a real advantage over gas-powered large vehicles.

I traveled to Nashville and had the opportunity to drive the new Pathfinder Hybrid and came away impressed. When driving the vehicle it feels very much like the gas-powered version. The Hybrid was designed to introduce the new hybrid powertrain system to enhance fuel economy and reduce CO2 emissions but with no reduction of driving performance, passenger roominess or cargo capacity. The designers used a space-saving Li-ion battery fitted under the 3rd row seat which preserved Pathfinder’s 2nd row sliding functionality and easy access to the 3rd row. You get all of the roominess and comforts of the new Pathfinder without making sacrifices for the hybrid technology.

The Pathfinder’s standard 3.5-liter V6 is replaced in the Hybrid by a new supercharged 2.5-liter gasoline engine and an electric motor paired with a compact Lithium-ion battery. The 15 kW electric motor and gas engine were designed to work in tandem to provide performance similar to the conventional Pathfinder. The Hybrid system is rated at 250 net horsepower and 243 lb-ft of torque while the 3.5-liter V6 has 260 horsepower and 240 lb-ft of torque. These similar numbers are evident in the driving experience when you compare both vehicles.

The result, however, is improved fuel economy as the Hybrid is rated at 26 MPG combined (25 city and 28 highway), an increase of 24 percent over the standard Pathfinder. Like the gas model, the Pathfinder Hybrid has a large 19.5-gallon fuel tank for a highway driving range estimated at more than 546 miles. These MPG numbers won’t challenge smaller vehicles but have to be evaluated in light of the size and performance of this vehicle. For example, the hybrid can tow up to 3500 pounds when properly equipped which is less than the gas-powered Pathfinder’s 5000-pound towing capacity but is still very useful.

Like all hybrids the Pathfinder has a regenerative braking system that automatically recharges the battery by converting the vehicle’s kinetic energy that would be otherwise lost in braking. Still, I would have liked to see more features in the dashboard gauges showing me how well I was using this system and the electric motor as these features are a big selling point in other hybrids.

The Pathfinder Hybrid offers an appealing option for consumers looking for a large vehicle, as now you can get all the benefits without being stuck with a gas guzzler. Take it for a test drive and you’ll see immediately that you’re not sacrificing performance or comfort for the gas mileage boost.
