The power requirements for overnight charging should be lower.
You don't need ad DC 150kW at your parking spot.

lower power chargers work for overnight charging scenarios, but 150kW charger at your parking spot gives flexibility and convenience esp during unexpected moments when you need a speedy topup or only have so little time to charge. for shared parking spaces, it will really reduce wait times and congestion. my dua sen

Tuju residences at jalan kuching. SA told me every carpark units will be prepare with EV infrastruture. But owner need to apply their own EV wall.

How many 11kW charger cable could be pulled from condo db? how much cable will cost from condo db to car park?

Hmm, for my unit 3 parkings are provided. The allocated EV parking is the same floor as my other 2 parking lots

sunway flora also EV charging infra-ready

meaning ac charger can be installed?
AC 7kw or 22kw type charger can be install?

According to the tuju salesperson, all car parks are ready for AC charger installation. This is the only development I’ve visited recently that comes with its own EV charger installation for individual parking bays, plus 3 public EV charging ports in the common area (if I’m not mistaken).

As for the charging capacity, I didn’t ask, but I think it should be 7kW since it’s installed at your own parking bay—can slowly charge overnight.

So, each charging port will have individual meter? or how the electrical bill charge?

should be individual meter. but i dun sure about the billing way , I didn't ask to details about this...

Spot on !!!

Assuming 500 units in the building, need to pull another 500 cables for EV charging from parking bay, and all the way to 500 units of individual meter (or just integrated into the unit's electricity meter 🫢 ... ). Imaging the cabling work involved for 5/6 storey of parking level. Also, imagine in future, if there is cabling problem or connection issue happened to your particular parking lot, who going to pay for checking and repairing works? That particular owner, or management???

Most important thing, safety !!!
Imagine 200 or 300 or 500 cars going on charging work at the same time, same premises, everyday .....

You're right to be concerned about the complexities of installing EV charging for 500 units. It's a significant undertaking! The cabling alone is a major project, but a reputable charging company will have experience in designing efficient and safe wiring solutions for large installations. They'll consider factors like load balancing to distribute power effectively and minimize the risk of overloads. They'll also be familiar with local regulations and permitting requirements, which are essential for safety and compliance.

For future maintenance and repairs, most reputable charging companies offer maintenance contracts that cover both the hardware and the installation. They should also have clear policies about who is responsible for different types of repairs. Many modern charging systems also have smart monitoring capabilities that can help diagnose problems remotely, potentially saving time and money on repairs.

You're absolutely right to prioritize safety. Charging hundreds of EVs simultaneously requires careful planning and robust safety systems. A good charging company will adhere to all relevant electrical codes and use equipment designed with safety in mind. They'll also implement load management strategies to prevent overloading the building's electrical system.

So, while the scale of the project might seem daunting, planning and engaging a reputable and experienced charging company is key. They can handle the complexities of cabling, ensure compliance with regulations, address safety concerns, and provide ongoing maintenance support.

usually, it would happen for all charge at same time, also condo car park usually not fully parked as well.

Westside 1,2,3 at dpc all also cannot get EV charger in common areas. Those who bought EV cars are either charging in their office or at public charging stations. So inconvenient!.

After talking to the agent from Tuju, what I understand from him:

Basically, there will have a main port where a direct line from TNB’s facilities is pulled to. This setup isn’t cheap, and it’s almost impossible to add later on.
So what they provided is actually the mainport allows you to run cable to your own parking bay. You still need to apply if you need to install own wall EV charger at your parking bay. For those car park bay within 10M, cable installation is free. Anything beyond that will cost extra.

If you have two parking bays, you can only install one charger, and the electricity bill for the charger will be included in your regular electricity bill.

As for capacity, the main port’s load capacity isn’t unlimited. If the demand gets too high, they might limit future EV charging applications. For typical daily usage in city, one day drive 30-40km, you’d likely need to recharge every 4-5 days, not day day ma....

There’s no specific rule from Bomba about EV charging for building now, but soon or later, they will work on this. However, I believe TNB will handle it in safer way.
For Tuju, they actually separate the carpark from the main parcel, which I think makes it feel safer.
