The government has recently unveiled plans to enhance the Electric Vehicle (EV) ecosystem by installing 60,000 charging points by 2030 in Singapore.
Despite this initiative, important questions persist: Is the current infrastructure sufficient to support government grant objectives? Who will supply the additional power capacity necessary for the uninterrupted operation of the charging points?
Geoffrey Chan, Principal Advisor at Delight Innovative Technologies, a company pioneering a ‘power system neutral EV charging (PSN-EVC)’, shared insights on this innovative system, successfully implemented in Hong Kong.
Here’s an overview of the flaws in current EV charging stations and how PSN-EVC aims to address them:
Existing Challenges in EV Charging Stations
Current EV charging stations require increased power capacity, leading to wasted investment and underutilization. Governments worldwide have invested in expanding charging infrastructure, but dependence on existing network capacity remains a challenge.
Additionally, fast chargers may negatively impact battery life, and establishing charging points at homes or workplaces can strain the existing power system.
Addressing Challenges with PSN-EVC
PSN-EVC utilizes ‘shadow charging’, where excess building load capacity is used to charge EVs without increasing the overall load. Successfully implemented in Hong Kong, this method ensures optimal use of available power without exceeding capacity.
Advantages of PSN-EVC include quick installation, minimal costs, and harmonized coordination between electricity use and EV charging. By eliminating the need for additional power sources, PSN-EVC offers a sustainable solution for convenient and efficient EV charging.
By adopting PSN-EVC in more locations, the transition to 100% EV conversion can be achieved seamlessly, benefiting both vehicle users and the environment.
