LTA, please clarify whether ERP 2.0 OBU power consumption is too high??

‘OBU’s power draw is comparable to an in-car camera’: LTA clarifies misconceptions about ERP 2.0 unit​

The rollout of the On-Board Unit (OBU) for ERP 2.0 has led to some questions about the three-piece setup for motor vehicles, and whether the new components will cause a huge power drain.

Responding to AsiaOne, a spokesperson from the Land Transport Authority (LTA) has confirmed that "the power draw is comparable to that of an in-car camera".

Comprising a touchscreen display, processing unit and an antenna, the new OBU is a computing device that allows motorists to access essential ERP and gantry information, real-time traffic updates and road safety alerts, while also enabling seamless payment with Cepas cards.

The OBU is part of the government's efforts to replace the existing ERP system, which has been in use for over 25 years and is approaching the end of its operational lifespan.

At present, more than 18,000 vehicles have been fitted with the new unit since installations began last August.

What's the fuss about the OBU's placement?
Placing the processing unit under the glove compartment has raised eyebrows. Netizens pointed out that such placement could potentially cause inconvenience or safety issues for drivers.

In fact, early adopters of the OBU had also raised the same concerns.

In response to this feedback, LTA announced back in March that drivers will have the flexibility to choose where to put their processing unit. In May, LTA further pointed out that the processing unit can be placed in locations such as under the driver's footwell or at the front passenger's footwell, as long as it is "technically feasible".

Existing car owners will be able to choose the preferred location of their OBU during installation, while new car owners should ask about possible placements at an authorised dealer.

Another updated feature following early adopters' feedback is a button on the display unit, which allows motorists to temporarily deactivate the Cepas card for complimentary parking without the need to manually remove the card. This feature does not affect payments for ERP charges.

Single-piece OBU not feasible for cars due to heat​

Netizens observed that vehicles would have three components installed, whereas motorcycles would only have one unit.

For motorcycles, the single-piece OBU was feasible given the outdoor ambient conditions. Considering that temperatures inside an enclosed vehicle may soar higher than typical outdoor levels, placing the processing unit on the dashboard could lead to overheating, potentially affecting its reliability.

With these improvements, is the OBU now more user-friendly? Watch the video for a round-up of everything you need to know about the fuss behind the new OBU and how to get yours installed fuss-free.

If current draw is low, can lta explain why the fuse for the IU blows?

If current draw is low, can lta explain why the fuse for the IU blows?

this one serious hor.

fire hazard or not?

 

[pwongkk]

this one serious hor.

fire hazard or not?

I encountered 2x the currentnt IU fuse blow. But my radio never kena.

So LTA better explain, why low current draw still can blow the fuse, not once but twice?

Fire hazard or not hard to say, if the high current draw causes the components to overheat or melt, that can have a potential to cause a fire.

 

[Mystyque]

LTA say current is comparable, not low right?

So the question is what exactly is comparable?

For example, the top speed of a stock Cherry QQ is comparable with a 2020 F1 car, both are less than Mach 0.3

We already know is bullshat from lta.
How can a 3 piece device draw comparable current from the current IU which has no display unit?

wow!
this one is serious.. current also can kill rite.

how come never notify the media ? but must have proof hor.. dont wait kenna sue by LTA.

This sounds more like a govt. mouthpiece for propaganda only leh

What is the fuse spec? (They will normally engrave 10A, 20A ... etc)

It's not the standard car fuse, it's the cartridge type with glass in the middle and 2 metal contacts at each end.

Rating is 10A, 250V.

 

[pwongkk]

I still have the receipt as proof of fuse replacement.

The 2nd time I DIY change myself.

For the IU to suddenly draw 10A and burn the fuse, there must be something wrong with it. Can't blame on other accessories as the IU has it's own circuit.

Woah so thats 120W.
Did the fuse blew when car was parked or when you were driving halfway?

 

[xArchangelSGE]

They will clarify after erections.

 

[Elfblade]

For something to overheat, means the current draw must be substantial.

LTA please clarify how much is the power draw when the car is parked, how long can we leave our cars parked before the car battery becomes too weak to start the engine

Can LTA please quash the rumours that the OBU would suffer permanent damage if internal battery of OBU becomes flat

Waiting for early adopters car to Sexplode so OBU can U-Turn.

 

[(^@^)"]

The fire under LTA's arse just keeps getting stronger and stronger

Don’t worry. They have really thick skinned people to ignore all the criticism and will still bulldoze their bullcrap through all the opposition.

 

[(^@^)"]

I am going to ask this taboo question. Did someone gained some benefits by dumping a 1990s technology on us, helping some companies clear their old inventory?

A current surge or the draw is higher than the fuse may have caused it to burn. Someone prob miscalculated the power draw/usage.

Should have been caught during CE testing.

If more incidents like this we can prob rule out faulty unit.

Miner's the old IU that is currently in use.

Like ine bro mentioned, the connection is always on and not connected to ACC. At least in ACC, the unit is off when the ignition is turned off.
