Perhaps you remember when Volvos looked like they were carved from wood by an axe while other manufacturers were going windswept and aerodynamic. Then they finally switched to svelte a decade or so back and improved on that while others have moved on to muscular, angular and blocklike. One wonders who is leading whom.
Volvo Cars is currently evaluating the viability of a fully battery-electric vehicle (BEV). This year, Volvo has built and internally testing a small number of prototype versions of a BEV version of its C30. In addition to focusing on performance and safety, much of the focus is on integration of the electric propulsion system with the rest of the car.
The electric Swedish stunner is built on the C30 hatchback and comes with all the safety, comfort and space we expect from Volvo. The company already is working on a Volvo plug-in hybrid due in 2012, but seems to be building a city car with the C30.
Lennart Stegland, director of Volvo Cars Special Vehicles, said in a corporate statement, “The Volvo C30 is the first model we will try out with electric power. This car’s excellent properties in city traffic and its relatively low weight make it particularly suitable, since electric cars are primarily expected to be used in and around cities and for daily commuting.”
Are we seeing the slow death of the SUV, minivan and others with a birth of a city car, over the road car and other more energy wise vehicle types? Or are we just seeing a new car class being born? The Volvo C30 is far more substantial than the Smart Car and other two seat city car contenders.
The C30 BEV is limited to a top speed of about 130 km/h (80 mph)—more than sufficient, Volvo says, for a city car application. Acceleration from 0 to 100 km/h (62 mph) will take less than 11 seconds. The car would have a range of up to 150 kilometers (93 miles)—longer than the distance 90% of all Europe’s motorists drive per day and surely covers a wide swath of U.S. motorists as well.
Volvo’s battery choice for the C30 BEV is designed and developed in the U.S. by EnerDel, Inc., Ener1’s U.S. battery subsidiary. This adds to the recently announced collaboration with Volvo on the V70 model plug-in hybrid demonstration vehicles being road tested in Europe starting this fall, which are also using the EnerDel lithium-ion batteries.
Using EnerDel’s EV chemistry, hard carbon and mixed oxide in a lithium-ion battery pack, yields gross nominal power of 24 kWh lithium-ion battery pack and is said to be considering a 12 kWh pack. The EnerDel battery set is custom-made and is a split battery pack. With an energy content of more than 24 kWh nominal energy, Volvo plans that 22.7 kWh is used to power the car.
The electric traction motor is located under the hood, just like the engine in a conventional front wheel drive car. One of the priorities of the Volvo project is to find the optimal placing of the battery. Most likely it will be the prop shaft tunnel and where the fuel tank normally is located. These locations are within the car’s optimized crumple zone in the most common collision scenarios.
Recharging the C30’s EnerDel battery pack via a household supply at 230V, 16A would take about eight hours. That’s a rate similar to a mid sized window air conditioner, meaning consumers would only need a 20 amp 240 volt outlet where parking overnight.
Volvo has already built a small number of the cars and begun testing. Volvo says the early testing has focused largely on integrating the electric drive train with the rest of the car.
Volvo always emphasizes its focus on safety, saying that if it chooses to introduce an entirely new type of electric car on the market, it will be just as safe as any other car bearing the Volvo badge. Volvo has been working to theoretically identify all the electrification-related safety scenarios in the stages before, during and after a collision. After careful study of these scenarios, the company’s engineers will create solutions for handling each and every situation identified, “guaranteeing that any future electric cars fully match Volvo’s safety standards in every respect.” Considering the Volvo record, that is as sure a thing as can be credible.
Volvo plans the main electrification track over the coming decades will be plug-in hybrids. That track applies in particular to the company’s larger car models. The combination of an electric motor and combustion engine is a solution that probably has the greatest potential from both the technical and commercial viewpoints. Plug-in hybrids offer long range, good environmental performance and at the same time limited dependence on expensive battery technology while cutting back on the fossil fuel demand.
From the three point seat belt invented at Volvo and licensed without charge to anyone world wide, to the research and development of the O2 sensor (called lamdasond) also made available at very low license rates to encourage development worldwide, Volvo is a major innovator in motor vehicles. Maybe those ax carved body designs were early visions of what’s to come, and they did come.
Volvo’s Paul Gustavsson, Director of Electrification Strategy at Volvo Cars said, “The consumer must feel that this battery electric car is attractive both to drive and own. In order to ensure this, we feel that electric cars will have to be as comfortable and safe and offer similar levels of performance as cars with other power sources. The learning from the C30 BEV project will help us to fulfill all these criteria and showcase Volvo’s determination to drive developments in the field of electrification.”
Volvo is currently owned and a division of sorts of the Ford Motor Company, the one last standing non-bankrupt U.S. automaker. For all the storied past from Ford both good and bad, the current leadership have been excellent stewards. Volvo is said to be available for sale, but the price must be very high. It has to be, one would think, the Volvo status is the safest, sanest and efficient cars that are priced within reach of the U.S. and world middle class. Volvo may be a small make, but its one of the major ones to watch.

Nature has gifted us with a divine source of energy – The Sun, which directs its rays all over our planet for FREE. And yet we vast majority of humans started realizing its importance after a million years of evolution.
It is said that A 1-kilowatt of solar energy will prevent approximately 170 lbs. of coal from being burned, 300 lbs of CO2 from being released into the atmosphere and 105 gallons of water from being consumed each month!
An energy source so abundant, so pure, yet so wasted by many for so many centuries.The only reason beyond such a basic flaw is lack of application of technology efficiently.
But the tables have turned now…
The technological advancement in the past century has achieved many milestones. One such being the invention of SOLAR PANEL. In straight terms; solar panel could be defined as an array of small cells that produce electricity or heat when light shines on it.
But yet again, application of solar panel was more impractical due to many reasons like:
- Expensive in nature
- Less energy efficient
- Uncertainty due to climatic change
Research went on for many years on this vital product by many countries. For some decades, achieving the heights into solar generated power for your home electricity was viewed by many as not viable, tentative and pricey dream to human race.
But they say – “You do not choose a dream, but the dream chooses you by means of who can achieve it. And probably “solar generated power for your home electricity ” dream chose HUMANS. And one fine day it happened. An optimum point was achieved in both efficiency and expense for the product.
A skilled renewable energy specialist designed rather a simple method for you to construct solar panels by using low cost materials which could be found at any local hardware store. And you don’t even have to know the construction terminology to build this.
There happens to be quite a few people around the globe, who have been guided by this method to harness solar energy in the most efficient manner. And the best part is, some have even managed to earn a steady income by selling the unused, extra power they have generated to the local power supplier.
I am sure with this method, you would definitely be guided to harness solar energy in the most efficient manner and in turn rejuvenate the spirit of the earth.

When a Nampa Idaho man made do it yourself modifications to his natural gas piping under his home the results were truly explosive.
September 21, 2009 Boise, Idaho – A man in Nampa Idaho made do it yourself modifications to his natural gas piping under his home and his home is now completely destroyed and he is recovering in the hospital with third degree burns.
The local gas utility company and fire department officials in Idaho reported that the homeowner apparently made repairs or modified his natural gas piping under his home in the crawl space. It was reported that his natural gas usage increased five fold in the days leading up to the home explosion.
While natural gas does not have any odor the gas utilities add odor before it is delivered to their customers and why this homeowner did not smell the gas in his home prior to the explosion is not clear. Only a small portion of this home remains standing and most of the home and it’s contents are in the neighbor’s yards and streets now. Truly amazing that he survived this explosion inside his home.
There is no code or law against any homeowners working on their own gas piping in their home in Idaho as in many states but there are specific codes and rules to follow. Ameri-Serv, Inc. Heating and Cooling recommends that homeowners get professional help when repairing or modifying their gas piping. If the homeowner does it themselves it is strongly recommended that the gas piping be pressure tested with air prior to allowing it to be placed back into service.
However, you can damage your home appliances if you do not perform the pressure test correctly. Terek Worley with Ameri-Serv, Inc. indicates that “If you are not sure how to pressure test your gas piping without damaging your appliances then you should call a professional to make sure you are not at risk.”
With today’s economic situation it is understandable that homeowners are doing more repairs to their homes. Ameri-Serv, Inc. Heating and Cooling wants the do it yourselfers to be extra careful when repairing or modifying their gas piping and not take unnecessary chances with their family and their home. Call a professional, gas piping repairs and modifications are not that expensive and having the assurance of the job done right is well worth the investment.
