The price point for the EV chargers varies drastically due to how differently they’re designed and have additional features that could lead to a bump in cost. However, EV-Sifu’s selection of its own chargers employed safety features equivalent to those of higher-spec chargers at a non-price gouging rate. Do not be mistaken, though, as our affordable prices aren’t cause for embedding low-quality components to put our customers’ safety at risk. Our offered EV chargers have undergone vigorous testing and quality assurance before deployment of availability for purchase.

 

Single Phase and Three Phase

The housing supply phase will be important in determining whether you’re eligible to accommodate the EV Charger. The selection based on the housing supply will limit the charging (kWh) supplied to your EV. Housing supply service is split into two categories. Regardless of whether your house is built old or new, it’ll only be either or:

 

Supply service type	Single Phase	Three Phase
Average Load current capacity fuse in homes	32A /40A/ 63A	63A/100A
Operating Supply Voltages	230V	415V
Choice of EV Charger	It is recommended that a 7Kw charger be installed within single-phase capable units as the capacity for the load if using 32A for the fuse will surely lead to an overload-case scenario.	For the three-phase, the selection for EV chargers is much wider as the load capacity is more sizable at 63A per phase minimum. All types of 7kW to 22kW chargers are applicable to install within this housing supply service type.
Upgrades	·         To 3 phase: The wiring may need reinstalling as the existing wires can’t perform nominally. If not, additional wiring needs to be routed to the incoming of the DB.     ·         For single-phase 7kW 32A chargers, installation requires an upgraded main breaker fuse from 32A to 63A.
The average cost of the upgrade (RM)	2000-10,000

 

 

EV Charger Components- DB/Sub-DB costs.

Component type	Average Cost Range in the Market (Loose Item)	Price difference comments
MCB (Miniature Circuit Breaker)	RM 30 – 40   Reputable electronic component makers are within this price range, which include   ·         Hager ·         Maxguard ·         Schneider ·         ABB	The MCB can be 2-pole (single-phase) or 3-pole (3-phase) and vary in sensitivity. Both are priced differently, as the latter offers more material in construction and a higher protection rating.
RCCB (Residual Current Circuit Breaker) TYPE A / B	RM 50 – 250   Reputable electronic component makers are within this price range, which include:   ·         Hager ·         Maxguard ·         Schneider ·         ABB	The current ratings of the RCCB (e.g., 25A-63A), the number of poles, and sensitivity differentiate the pricing structure of the components. A higher rating usually entails additional costs.   For EV charger purposes, the following specification is as follows: ·         Type A or B ·         Current Rating of 6kA-10kA ·         2-pole (Single Phase) – 3-pole (Three Phase)
4 mm² -6mm² single core copper cable	Currently, RM 41.71 and RM 52.31 are 5 meters long, respectively.	·         Copper costs fluctuate, so if you're considering installing it soon, the costs may differ. ·         The price also depends on how far you intend to run the wiring from the DB/Sub-DB to the installation point of the EV Charger. ·         Consider that three phases require three times the amount of wiring compared to a single phase, thus naturally associating higher wiring costs.
Sub-DB housing (PVC)	RM 10 – RM 60	The price ranges vary based on the length of the raceways and the space available for installation inside the sub-DB. The price is also dependent on the material of the Sub-DB.

 

 

EV Charger installation cost – From DB/sub-DB to EVSE unit

Component type	Average Cost Range (Loose Item)	Price difference comments
PVC Conduit	RM 1.50 – RM 2 per meter	The PVC conduit will provide mechanical protection to the electrical wiring installation routed toward the isolator and EVSE unit. The price of the PVC conduit is concurrent with the length of the wiring incoming from the DB/sub-DB.
Isolator (Switch Disconnector)	RM 30 – RM 100	The price varies due to differences in: ·         The number of poles configured (single pole – four poles) ·         Rating of electrical current load ·         IP-rating, EVSE units installed outside require the Isolator switch to be resistant to dust and water. ·         Additional features that upheave safety include integrated surge protection.
Conduit support accessories	RM 0.15 – RM 3.50	PVC joint connectors fit the PVC conduit, allowing efficient pathway travel to the EVSE installation point. The accessories consist of multiple joint-type connectors and brackets to secure the PVC conduit installation and differ in price.

 

EV Sifu Installation package

As a growing company, we strive to provide the best possible service to our customers without breaking the bank. The disparity in our installation price compared to the breakdown of each loose item component earlier might signify that we upcharge. However, remember that it includes our experience in installations that specifically cater to EV chargers for the past two years and a peace of mind 1-year warranty post-installation.

EV Sifu offers an installation price package of RM1350* that covers all the listed EV Charger installation components above (including a sub-DB, which will incur an additional RM 200 if the main DB does not have enough capacity) to connect to your chosen EVSE unit.

Additional cost for EV Charger installation

Some factors will incur additional expenses, which boils down to certain factors within the homeowner’s choice and regulation criteria.

• According to regulations set by Suruhanjaya Tenaga’s Guide on EVCS under 5.5 (5.5.1), installations for EVSE indoors are to be directed onto the outside walls to minimize distance from the electrical box and away from indoors except for an enclosed garage. Complying with this rule relates to an additional cost if it is above the 10 meters provided by us to pull away from the DB to the outside, with consideration to the installation point agreed by the homeowner.

 

• Trenching - underground cables buried are of different specifications that follow under (Table B.52.2 IEC 60364-5-52 2009) and are priced differently than the ones enclosed in PVC conduit outside. Trenching works are also calculated for every cubic meter removed. This scenario is for isolated garages not connected to the main housing or near the main DB that overutilizes the 10m provided 4-6mm ²wiring.

 

• Rectification works before installation—Our site assessment before installation allows us to gain insight into the condition of your electrical system. If the electrical system's performance at home is not nominal, it will lead to additional costs for the components necessary for rectification work.

 

Why choose EV Sifu for your installation of EVSE?

We understand and resonate with our customers when they want an affordable solution to their EV charger installation that doesn’t undermine the customers' safety. We hear you and prioritize the techniques that go into our installation so that it ties in compliance with the acts under our local electrical installation and Suruhanjaya Tenaga. Among them are:

• Excessive bending wiring/cable that eventually causes failure points.
• Quality RCCB Type A from Japan that complies with electrical protection for EVSE unit installation as per electrical installation guidelines.

• We use components from brands renowned for their quality craftsmanship and standards that comply with the specifications for our installation.  An example would be the utilization of wiring from MEGA, whose wiring is entirely composed of copper, while other companies cheap out by the addition of other metals inclusive with the copper wiring.

• Sub-circuit installation for EVSE unit that does not impede the primary circuit within household appliances when tripped.
• Post-installation tests ensure that the installed EVSE is performing as intended.
• Inclusion of an Isolator to isolate the circuit between the EVSE and DB/sub-DB
• Hacking works are first liaised with the homeowner to reach a mutual agreement and gain insight into what may be behind the walls.
• We color-code our wiring works so that it's easier to identify which is which and for visual clarity of troubleshooting if an error ever occurs.

 

Uniform colored cables are color-coded by labeling of the colors that depict the L1, L2, and L3 wirings.

 

 

 

Excessive bending for the wiring is avoided and bending points are minimized.

 

How does EV Sifu manage to stay so cost-efficient?

• We manage to offer you the affordable prices you see now as we’ve successfully done hundreds of installations around Klang Valley. This has prompted us to be received well by vendors and suppliers alike as we continue to deduct their inventory.
• Expanding on cost efficiency, we don’t partake in using other agencies for installation services but instead take installation projects directly under our belt.
• These factual evidence of our services allows us to have complete control over our costs, giving you, as the customer, extra money to spend elsewhere.

 

Does the cost vary based on living location, such as Condo?

The only cost difference that might be included in living locations such as a Condo will be the wiring costs, as the installation point of the EV charger is unbeknownst to us until the site inspection is done to accurately assess limitations that we might need to work around with. Additionally, if the management requires, we can install a metered unit to install the EV charger so that knowing how many blocks of (kWh) energy are used is more accessible for both residents and management.
