For Buildings

For zero cost leasing, there is no cost to NLPRs for the EV charging equipment, LEW certification, cabling and installation and maintenance. Additional charges may apply if cabling exceeds 25m and if communications equipment, civil works or an electrical infrastructure upgrade are needed. There is a minimum 36 months contract period. There is no contractual period if NLPR purchases chargers using the EV Common Charger Grant (ECCG). 

36 months contract period for zero cost leasing. Should the NLPR continue with the service, the charger will remain. The charger must be returned in good working order (fair wear and tear is acceptable) if the NLPR discontinue. There is no lock-in period if the ECCG is used to purchase the charger by the NLPR. 

For zero cost leasing, there is no penalty for an early termination of contract. However, the MCST has a to buy out the electrical cabling and infrastructure at cost (5-year straight line depreciation applies) and return the EV charger units (fair wear and tear is acceptable). A removal and restoration fee will apply. The NLPR is free to engage their own contractor to undertake this work. 

If a charger malfunction is reported or identified through the EV Charger Management Platform, the unit will be repaired or replaced within 24 hours at no cost to the MCST. 

All our charging equipment conform to the National Public Charging Standards and comply with the Technical Reference for Electric Vehicle Charging Systems (TR25:2022). 

Each charging station has one Type 2 charging socket and will charge one vehicle at a time.

Yes you can. Actual cost varies depending on the NLPR’s preferred location. Costs will include cabling and installation, LEW fees, charger and communication equipment (if needed). Maintenance charges and “fit for use” inspection by LEWs may apply if the NLPR is operating the chargers directly.

The ECCG will co-fund the first 2,000 chargers in non-landed private residences (NLPRs) between 29 Jul 2021 and 31 Dec 2023. The ECCG will co-fund up to 50% of qualifying costs including charging equipment, LEW fees, cabling and installation, subject to a cap of SGD 4,000 per charger. Funding is on a reimbursement basis.

The ECCG will co-fund 1% of total parking lots rounded up to the nearest whole number. For NLPRs with less than 100 lots, only 1 charger is eligible. Priority is given to NLPRs with no existing EV chargers. Mixed-use developments can apply for the ECCG if the charger benefits more than one household and is exclusively for residential use.

NLPRs are encouraged to engage an EVCO. If the NLPR chooses to operate the chargers directly, then it has to provide LTA with electricity consumption and charger utilization data, extracted and recorded from the smart chargers for 3 years. Etron has been successfully reviewed by LTA as an EVCO.

Survey the number of current and expected drivers and whether the solution provides drivers with fair and equal access to chargers. Check if the electrical infrastructure can support the desired number of chargers. Compare the cost to drivers, ease of use and safety of the equipment. Confirm if the charging mode is good for EV batteries. We can help with a site assessment to determine the optimal deployment for your building.

Communications equipment and cabling may be installed to allow the charging stations to communicate with the EV Charger Management Platform. Additional charges may apply depending on the complexity of the installation.

Yes. If the visitor does not have the same charging network account, they will need a resident EV user to activate the charging station and the cost of charging will be borne by the resident EV user. If the visitor has an account, then charges will be deducted from their account. Priority at all times will be given to resident EV users.

ORBIS smart chargers have dynamic load balancing which allows up to 248 chargers to be installed per building without tripping circuit breakers. The chargers monitor the building’s real-time energy consumption and adjust the power supply to optimise charging speeds to EVs within available limits.  

Etron will assist the NLPR to determine the optimal number of charging stations. Additional charging stations can be added quickly as the number of resident EV users grows. A ratio of at least 1 EV charging station to every 5 resident EV users is recommended.

Yes, the system allows up to 248 chargers to charge EVs simultaneously but charging speeds can be affected accordingly. Etron offers free planning and consultations to NLPRs to optimise the number of chargers. This is to ensure meaningful charging speeds based on the existing electrical capacity. We will suggest upgrades if needed.

No, LEW endorsement is provided for every charger we install. However, a LEW needs to be engaged if the electrical infrastructure of the building needs an upgrade or alteration.

Charging stations managed by Etron are covered by a SGD 1 million 3rd Party Public Liability insurance policy. This is in addition to any insurance policy the MCST may have in place.

Any infrastructure upgrades to the property should positively enhance its value and make it more appealing to future potential buyers.

For non-residential MCSTs, we are able to provide various customised models e.g. per min or per kWh fee charging to meet your needs. We can also help to manage the various aspects of operating an EV charging network at your property e.g. electricity consumption monitoring, charger utilization rates, payment collection etc. Please contact us directly to arrange for a site visit and discussion.

Charging times vary depending on battery capacity. Charging is also affected by the available power and phase type of a building’s electrical supply. EV specific limitations and requirements can also affect charging speed. 

The below table shows estimated charging times from 0% to 80% for a sample of EV models when using the ORBIS Viaris UNI 1-phase and 3-phase model. 

Profit sharing is available. If the NLPR purchases chargers using the ECCG then profit sharing begins immediately. Otherwise, profit sharing starts once the cost of equipment and installation have been recovered.

For Drivers

Not for now. All our chargers utilise Charge Mode 3 which charges at a speed of 7.4kWh (1-phase) or 22kWh (3-phase), depending on the building’s power phase. With ultra-fast charging, 350kWh of power or higher is required. 

Ultra-fast charging also affects EV batteries. Researchers found that ultra-fast charging of batteries can ruin their capacities after just 25 charges. High temperatures and resistance from fast charging at commercial stations can cause cracks and leaks leading to potential safety issues according to the Institution of Mechanical Engineers. 

The lite usage monthly subscription package is SGD 90 per month capped at 200kWh of electricity consumed. This is equivalent to a drivable range of up to 1,300km per month depending on EV model (real world conditions may vary). There is no lock-in period for subscriptions. 

Higher-tier packages are available – SGD 113 for up to 250kWh for medium usage drivers and SGD 135 for up to 300kWh for heavy usage drivers. Customised packages are available if usage exceeds the highest tier, please contact us for more information. Prices are subject to quarterly revisions in line with the Electricity Tariff. 

If consumption exceeds the monthly quota, a per kWh rate of SGD 0.50 applies. Prices are subject to quarterly revisions in line with the Electricity Tariff. 

A User app is available for drivers to access chargers, make bookings, monitor usage and billing history, receive charge status notifications, make payments etc. 

Drivers can book chargers via the User App on a first come first served basis. If the booking is not used or canceled in time, a booking fee will be charged and the lot will be freed up for other drivers.

The ORBIS Viaris UNI has inbuilt DC current leakage protection to protect EVs and users against electrical risk. The equipment is also certified according to European Standards EN IEC 63000; EN 61851-1; EN 61851-22; EN 300 328 V2.1.1; EN 301 489-1 V2.2.0; EN 301 489-17 V3.2.0; EN 62311; EN 60950-1.

We are able to offer equipment, installation and LEW certification packages at competitive prices. Please contact us directly to arrange for a site visit and discussion.

The EV Early Adoption Incentive (EEAI), from now until 31 Dec 2023, offers an Additional Registration Fee (ARF) rebate of 45% capped at SGD 20,000 for new EVs. Under the Enhanced Vehicular Emissions Scheme (VES) from now until 31 Dec 2023, rebates will rise by SGD 5,000 to SGD 25,000 and SGD 15,000 for Band A1 and A2 EVs respectively.
