Electric Vehicle Charging Infrastructure
The Challenges
In recent years the problems of "range anxiety" associated with electric vehicles (EVs) have been alleviated by the introduction hybrids (HEVs) and plug in hybrids (PHEVs) and the development of higher energy density batteries capable of storing more energy in the same space. With the increasing popularity of electric vehicles, "range anxiety" is now being replaced by "charging anxiety". This page addresses the issues associated with providing suitable EV chargers like DC Ev Charger or AC EV Charger and the charging infrastructure necessary to support the growing population of EVs.
It takes about three minutes fill up a petrol or diesel engined car at a filling station with enough fuel to travel about 300 miles, costing about $35 in th USA and about ￡52 ($80) in the UK. To travel 300 miles in a small EV passenger car would need three full charges of a typical 25kWh battery used to power these vehicles costing about $2.50 per charge in the USA with electricity priced at $0.10 per unit (kWh) and ￡2.50 ($3.90) in the UK with electricity priced at ￡0.10 per unit. The low energy cost is one of the attractions of owning an EV. Unfortunately to put the 25 kWh of energy needed to travel each 100 miles into the battery in the same time (1 minute) that the equivalent amount of diesel fuel is pumped into the tank would require a power supply capable of delivering a power of 1.5 MegaWatts. To put this into perspective, 25 kWh is the amount of energy an average household consumes in a whole day. Providing electrical distribution facilities to allow users to consume this amount of energy from the electricity grid in one minute is not practical and even if it was, no EV battery could accept energy at this rate. On the other hand neither is it practical to take 24 hours to charge the battery in a passenger electric vehicle.
The solutions don't just involve the development of chargers, they involve the design and roll out of a network of public and private charging stations with associated user authentication and billing systems, public safety and planning issues, the negotiation of international standards and beefing up the electricity grid to carry the increased load. There are no single answers to these issues. On the one hand, national and international standards organisations attempt to find definitive solutions to these issues, but there are so many competing national standards. On the other hand commercial enterprises attempt to leapfrog the competition by coming up with new and unique innovative solutions to differentiate their offerings.
Except for EV Charger, another indispensable part for EV is EV Connectors. At the heart of any specialist electric vehicle, such as hybrid trucks and electric construction vehicles, are its connectors. Connectors ensure power is distributed reliably throughout every electrical system, from the battery to the powertrain, to dashboard electronics and other specialist equipment. They also help in the event of faults, allowing operational systems to keep functioning in the case of a singular system failure.
The National Grid in the United Kingdom is anticipating a huge demand increase for power when 100% EVs make up a significant portion of British road traffic. Even in the immediate future, power demand is expected to ramp up as more non-passenger vehicles begin to electrify.
The trend of electrification doesn't only apply to powertrains. New specialist vehicle designs are exploiting new technologies in safety & security, convenience, live driver insights, and even advanced body & chassis systems. Vehicles are about to become more connected, more useful, and even more frictionless to own and maintain.
Connectors are able to improve power deliverability and reliability, while they also ensure the systems can be maintained easily. Connectors are available in a variety of sizes, weights and specifications, DC EV Connectors, AC EV Connectors, High voltage connectors safely guarantee high voltages are distributed through powertrains, for example.
And if you want to finish EV charging, there are some other essiential parts that you can't missing. They are EV Charging Power Box, DC Charging Stacks and QR Code Payment System.
