Singapore’s power supplier SP Group will test four charging points that can restore electric vehicle (EV) battery power to balance fluctuations in electricity production and consumption.
SP Group said on Thursday (July 8) that vehicle-to-grid (V2G) technology can help improve the reliability of the grid so that the grid can cope with the expected large-scale adoption of electric vehicles in Singapore by 2040.
V2G can also adapt Singapore’s power system to increased renewable energy capacity, among other benefits.
SP Group installed four charging points in one of its substations for testing. The
test is not open to the public and will be conducted on two Nissan Leaf cars. It will be completed in June 2022.
Nissan Leaf is currently the only model in Singapore that supports V2G.
SP Group stated that it will focus on areas including charging electric vehicles during peak and off-peak hours and voltage management in power distribution systems.
“If V2G technology proves to be feasible, it may be beneficial to electric system and electric vehicle owners because it can be used as a cost-effective solution to supplement larger energy storage systems to overcome intermittency, while electric vehicles Car owners can use electric car batteries when necessary to receive payment,” SP Group said.
Intermittent refers to a power interruption.
SP Group said that traditional power plants have played a role in alleviating intermittency, but electric car owners can now contribute V2G technology.Link Link Link Link Link Link Link Link Link Link Link Link
Taking solar electric vehicle charging points as an example, SP Group stated: “When solar power generation drops due to rain or cloud cover, electric vehicles connected to the system can make up for the decline in supply.
” Cars can store excess energy. Stanley Huang, CEO of
SP Group, said that this trial is another step in supporting Singapore’s green energy transition. The
government has stated that it will phase out gasoline vehicles by 2040. Kazakhstan has pledged to equip eight cities with charging points by 2025. , To build 60,000 charging points on the island by 2030.

Where to insert electric vehicles in Singapore and how much does it cost With the expected increase in the use of electric vehicles, now is a good time to start testing.
He added that if people change their mindset and consider each car as a small source of energy that can be fed back to the system, then the V2G system can be implemented here.
“It’s basically about balancing supply and demand. In some periods we can have excessive demand for electricity and electricity is underutilized,” he said.
But Dr. Ong noted that one challenge will be determining a pricing structure to attract enough electric car drivers to return power to the grid.
“Different needs must also be considered. For example, the needs of private car owners are different from the needs of taxi drivers or transport fleet operators,” he added.
