Car aircon does not use power from the battery
there are multiple parts for the HVAC system in a car, such as HVAC control unit (or controller), blower, evaporator, compressor, condenser.

nowadays, the compressor is electronic rather than belt driven. so all the HVAC items that requires energy, are electric.

they take power from the alternator

the car battery cannot support the AC system

In a tunnel cannot track liao.
I believed can.
My car stereo is connected to my mobile phone, it can track the full journey inside the tunnel.

It when it is not connected to my mobile, it is unable to pinpoint my location.

The mobile signals does play a part.

This is what they say now but it remains to be seen if it will be the case since there's limited testing and insufficient usage data

I understand from my LTA friend that the pilot batch only took place last year so it's too early to tell if issues would surface once we get a bigger sample group
I am only harping on the repeatability of the route data. Same route travelled everyday, no deviation. Will I get the same milage for all trips?

Can ask your friend to clarify this?

So far no one from lta answered or clarified. If the system is not able to produce the same precision tracking results, there is a chance of overcharging. How is lta going to address this?

If there is no solution to precision accuracy, then they better not implement this until it is fully resolved.

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 :s11:

Can LTA please quash the rumours that the OBU would suffer permanent damage if internal battery of OBU becomes flat :s11:
Very hazardous item

My friend is just a lowly engineer and he's not even part of the program - he was just used as a guinea pig

I have not seen the specifics on how they plan to do distance charging, whether it's by the M or KM, but generally GPS is accurate to within 10 metres bah

Anyway, I am just guessing but the same route may yield different pricing if they really implement distance and traffic based pricing i.e. if the road is packed and virtual gantries come into play, we may end up paying more, hence taking a longer route may be cheaper

Possible to disconnect the erp if we leave the car in the carpark when travelling overseas for a few weeks?
the connection should not be directly connect to the battery.

should be connected that way when u start the car then it turn on.

They can explain it away with surge pricing

They may say it’s confidential cannot tell you

They might add it’s in the interest of national security like nation’s reserves or will create divide like employment stats of PR vs sinkies

If there's a difference or not being accurate, the whole system is not reliable from the start.
