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.
