An easy-to-understand and engaging exploration of the battery's development across history that reveals current technological advances, celebrates the innovators who have led the charge forward, and shows how the electric battery represents the path to a low-carbon future.
The standards will also help to ensure that these historic investments in EV charging create good-paying jobs and that EV chargers are well-serviced by requiring strong workforce standards such as Registered Apprenticeships and the Electric Vehicle Infrastructure Training Program (EVITP). Through the White House Talent Pipeline Challenge, International Brotherhood of Electrical Workers (IBEW) has certified 20,000 electricians through EVITP.
AN ELECTRIC VEHICLE FUTURE THAT IS MADE IN AMERICAThe Build America, Buy America implementation plan for EV charging equipment reflects the success of the Biden-Harris Administration at spurring new domestic investments in the manufacture of EV fast-charging equipment. The rapidly-expanding industry is ramping up production to make high-quality, Buy America compliant chargers, creating good jobs and helping the Unites States strengthen its leadership in clean energy manufacturing. That strategy will ensure that electric vehicle chargers purchased through the NEVI program will be assembled in the United States, effective immediately, and fully compliant with Build America, Buy America requirements for manufactured products by July 1, 2024 to support investments in the supply chain consistent with an aggressive expansion of domestic manufacturing.
Looking beyond 2017, scientists envision a new generation of batteries made of low-cost, or even no-cost, materials. The lithium-air battery, still in early development, uses oxygen sucked in from the atmosphere to drive the chemical reaction that produces electricity. In the process, oxygen combines with lithium ions to form a solid compound (lithium peroxide). During charging, solid oxygen reverts back to its gaseous form.
Fast forward again -- this time to the 1990s. In the 20 years since the long gas lines of the 1970s, interest in electric vehicles had mostly died down. But new federal and state regulations begin to change things. The passage of the 1990 Clean Air Act Amendment and the 1992 Energy Policy Act -- plus new transportation emissions regulations issued by the California Air Resources Board -- helped create a renewed interest in electric vehicles in the U.S.
CHARGING FORWARD covers eight specific target areas to lay the foundation of our research and assumptions, including economic assumptions, propulsion systems technology, battery technology, fuel cell technology, government regulations and subsidies, electric supply and charging infrastructure, hydrogen supply and fueling infrastructure, and total-cost-of-ownership. These items are outlined in detail in the analysis PDF document, part of the three deliverables provided with the findings.
People tend to follow a charging hierarchy that starts at home. Most individual passenger cars remain parked for eight to 12 hours at night, and home charging can be easy and often cheaper than charging elsewhere. The reasons: in most countries, residential electricity is cheaper than commercial or industrial electricity, and most charging can happen overnight when off-peak electricity prices are lower.
The kilowatt capacity of a charger determines the speed at which the battery receives electricity. AC level 1 and level 2 are most applicable for homes and workplaces because of the long periods cars remain parked and their lower cost: a simple level 2 for a home can cost as little as $500. DCFC chargers are most applicable in situations where time matters, such as on highways and for fast public charging.
Currently, the business cases for home or workplace level 2 chargers are straightforward, given low up-front capital and operating expenses. Making the business case work for public DCFCs is more difficult. The reasons include higher up-front capital, higher operating costs, and currently low utilization. In the near term, this raises a critical question: Who will provide the necessary capital for public charging while utilization rates remain low, particularly in China where the need for public charging is higher
Time-Based Control (also referred to as load shifting) helps you maximize savings through smart charging and discharging of your Powerwall. If your electricity prices vary during the day, you are likely on a time-of-use plan, and Time-Based Control would present the best economic value for your system. Time-of-use plans are utility rate structures where electricity prices may vary depending on the time of day, the day itself or the season.

Previously we saw that a semiconductor diode conducts current in one direction only when forward biased from anode to cathode, but not in the reverse direction acting a bit like an electrical one way valve. One widely used application of this feature and the power diode in general is in the conversion of an alternating voltage (AC) into a pulsating voltage (DC). In other words, Rectification.
Q/A 100 V battery is to be charged via a single diode and series resistor from an ac supply with a peak voltage of 200V. Calculate the value of the series resistor which will result in an average charging current of 1 amp. Assume that the diode has a constant forward resistance of 2 and that battery has a constant EMF of 100V and negligible internal resistance.
Wireless electricity is certainly a complex area, which is what Renesas excels in. When integrating a wireless charging system into a device, one must first decide which wireless power standard is most appropriate for the application. In some cases, Renesas offers dual-mode solutions to maximize interoperability and convenience.
"eTransEnergy will support CATS with workforce training, performance data, procurement, electrical service management and installation of battery-charging infrastructure at CATS bus facilities," said CATS CEO John Lewis.
Power Control Unit A Power Control Unit (PCU) is located in the front of the vehicle, just above the electric motor. The Honda-designed PCU controls the total operation of the Fit EV's electric powertrain, including regenerative braking and recharging functions. 59ce067264
