Singapore has been accelerating its efforts to reduce carbon emissions in land transport. These include dangling incentives to get drivers to be early adopters of electric vehicles (EVs), rolling out more charging points across the city, as well as adjusting the Certificate of Entitlement to include more powerful EVs under the mass-market Category A of vehicles.
With all that is going on, how much do you really know about EVs? Take our quiz to find out if you’re ready to join the electric journey. Answers can be found at the end of the quiz questions.

Answers:
1. There are only around 20 moving parts in an electric engine, compared with nearly 2,000 in an internal combustion engine, so your electric vehicle will need a lot less maintenance.
2. A plug-in hybrid vehicle (PHEV) can be charged through regenerative braking and the power this produces varies depending on many factors. Ultimately, the PHEV still needs to be plugged in and charged using a wall outlet or charging point.

3. Global car makers use lithium-ion batteries to power their electric vehicles as they have good energy efficiency and low self-discharge among other reasons.
4. Singapore drivers typically cover an average distance of about 55 kilometres per day while EVs easily give a range upwards of 200km. Thus, the average driver in Singapore only needs to charge his electric vehicle once every few days.
5. According to their manufacturers, the fully-electric BMW i4 eDrive40 delivers a range of up to 591km; Tesla Model 3 can go up to 547km, while the BYD e6 has a range of up to 522km.

6. Singapore is targeting to have 60,000 charging points by 2030 – with 40,000 in public car parks and another 20,000 in private premises.
7. Most manufacturers offer 5-8 years’ warranty on their EV batteries. BYD, which produces its own Blade battery, offers a Battery Warranty of 8 years or 500,000km (whichever comes first).

8. You can charge your electric vehicle when slowing down or decelerating in what is called regenerative braking. It is a way of taking the otherwise wasted energy from slowing down the electric vehicle and using it to recharge the car batteries instead.
9. Electric vehicles have instant torque. At zero speed, the electric motor can deliver the maximum available torque which translates to very good launch capabilities of the vehicle. An internal combustion engine cannot deliver maximum torque from minimum speed (idle). They also need more time to reach maximum torque because of engine dynamics (such as air and mechanical inertia, and turbo lag).
10. Almost half of the world’s electrical vehicles are in China. The country has announced that 40 percent of the cars it produces will be electric by 2030. The increased production of EV cars and batteries is expected to help drive down worldwide costs for both.
