Overcome the green transport challenges: electric vehicle

The number of usage in electric car or EV car is increasing, this is great as it  help to maintain the balance of environment and also they together to walk along the government to achieve the idea of world with sustainable transport. However, to achieve this there are lot of challenge that will counter as this is  a new innovation with  a lot of improvement needed.

Some regions are growing faster than others. For example, China, the world’s largest electric car market, has formulated a national policy around the technology due to environmental issues. China’s share of the electric vehicle market is expected to reach 57% in 2019, up from 55.5% in 2018, according to Frost & Sullivan. “If you walk out of the airport in Shenzhen, China, for example, 90% of all taxis are electric vehicles. By 2021, which is not far away, every single bus in China will need to be pure electric,” Moxey said. “China can steer the direction quite easily through government legislation. That’s not so easy to do in Europe or North America.”

Let’s see how to overcome the major challenge which is the limited range and shortage of station.

LIMITED RANGE

·       Battery swapping

Battery swapping is a strategy to avoid range anxiety that allows electric cars to extend their range through a battery switch station. At the station, the depleted battery is swapped for fully charged battery in about the same time that it takes to fill up a car with gasoline. Battery swapping is common in warehouses using electric forklift trucks.


·        Chevrolet Volt

General Motors describes the Chevrolet Volt as an electric vehicle equipped with a "range extending" gasoline-powered internal combustion engine (ICE) as a genset and therefore dubbed the Volt an "Extended Range Electric Vehicle" or E-REV. When the battery capacity drops below a pre-established threshold from full charge, the vehicles enters charge-sustaining mode, and the Volt's control system will select the most optimally efficient drive mode to improve performance and boost high-speed efficiency. The range in EV mode of the second-generation Volt was increased to 53 mi (85 km).


SHORTAGE OF CHARGING STATION

There are increase in number of electric vehicle , however the number of charging station is still not increasing. That is why government need to take part and build more charging station especially within area with a high number of electric car. For example in US The International Council on Clean Transportation, in a report released Tuesday morning, said $1.3 billion would be needed to make the necessary additions to home charging for electric vehicles and $940 million for workplace and public charging for the 100 U.S. metro areas with the highest populations.

POD POINT - ELECTRIC CAR HOME CHARGING

You can charge an electric car at home using a dedicated home charging point (a standard 3 pin plug with an EVSE cable should only be used as a last resort).

  • Electric car drivers choose a home charging point to benefit from faster charging speeds and built-in safety features.
  • Charging an electric car is like charging a mobile phone - plug in overnight and top up during the day.
  • fully installed home charging point costs from £449 with the government OLEV grant.
  • Home charging points charge your car at 3.7kW or 7kW giving about 15-30 miles of range per hour of charge (compared to 2.3kW from a 3 pin plug which provides up to 8 miles of range per hour). 




Partnering with Tesla to Construct the Largest Contiguous Electric Vehicle Charging System in the World

“It’s one thing to build one Supercharger site, but it’s a totally different thing to build 100 at a time, or have 40 or 50 in construction at any given time. Black & Veatch brought an ability to be able to expand rapidly, bring on the resources necessary and also manage the construction of a complex project like that – all concurrently.”

Conclusion: Urban Transportation success in Vancouver, Canada

Image
Vancouver has managed a near-miraculous transformation of its city transportation. Today, 50% of journeys are made by sustainable means–on a bike, walking, or using public transit. The city set a goal that 10% of all commutes would take place on bikes by 2020, and it hit that goal four years early. Street Films interviewed the people behind this success, along with citizens who are enjoying their newly car-independent city, in this new movie:  Vancouver’s Multi-Modal Success Story.   The story is long and began back in the 1960s when Vancouver rejected freeways. The city remains the only major North American city with no freeways within city limits, says Vancouver’s former chief planner Brent Toderian. Instead of ripping up the city, and building a bridge across the bay, the citizens instead decided to create the Sea Bus, a ferry service that takes 10 minutes to cross the water. Today the plan is multi-modal. Walking, bikes, and transit all link up so you can travel car-free...

  Green Transportation Policy News      The National Transport Policy 2019-2030 (NTP 2019-2030) which was recently launched by Prime Minister Tun Dr Mahathir Mohamad is set to cater to Malaysia's transportation needs into the future. According to government statistics, carbon emission in the transport sector is largely from land transport, constituting 90 per cent or 48,200 ktonne and 67 per cent is from cars. Thus among the main objectives is to ensure efficient and sustainable use of resources and minimise environmental pollution. With the nation's total carbon emission cited at 7.9 tonne/capita (based on 2011 statistics) it is no wonder that environmental protection is highlighted as one of the main anchors of this holistic vision. While the nation needs to stay competitive and serve the logistic needs of businesses, organisations and its people, the NTP 2019 - 2030 addresses the shift towards environmentally sustainable transport via several strategie...

  PORSCHE TAYCAN WORLD ’ S FIRST ELECTRIC PORSCHE Porsche unveiled the luxury automaker’s first-ever fully electric car in September. Now, a little more than a month later, the German company is offering an even newer and less expensive version of its all-electric sports car — but it will still cost you six figures.   Called the Taycan 4S, the new model revealed on Monday is a sport sedan is capable of up to 522 horsepower. The four-door car comes with a price tag that starts at $103,800.   That’s more than $80,000 cheaper than the most expensive Porsche Taycan, the electric Turbo S, which sports a base price of $185,000 and can accelerate from zero to 60 mph in just 2.6 seconds. The Taycan 4S takes 3.8 seconds to reach 60 mph. Porsche also offers a Taycan Turbo that starts at $150,900 and accelerates from zero to 60 mph in 3 seconds. The Taycan 4S has a partial leather interior, according to Porsche, and the car also includes “comfort front seats” that can be...
