less then 38kw for 621.37 miles. My leaf would do 175 miles on 38kw.

…The car, designed and built by students, posted a verified time of 11 hours 52.08 minutes for the distance at the Australian Automotive Research Centre (AARC) in Wensleydale, Victoria.
That equates to an average speed of nearly 85km/h and secured the Sunswift Racing team the record for the ‘Fastest EV over 1000km on a single charge’.

I guess technically it is a “single charge” …..but continuous from the solar panels. ?

 

[ZeroEm]

the story went, it can go 100km on 3.8k. Don't know how big the battery was. was just figuring it used 38kw for 1000km. Thinking about it may have done the math wrong when converting to miles.

 

[Hillhater]

They dont state how big the battery is or what power the solar panels are ( but it looks like 3+ kW ?), so it is difficult to know exact energy available.
Maybe a 24 hr (day/night) comp in the future ?

kW? Or kWh? Very different things....

 

[ZeroEm]

Sorry amberwolf did not get my w in with the k. They stated that they can go 100km on 3.8 thousand watts. The did laps until hitting 1000km. So figured it was 38 thousand watts. They never disclosed the size of battery as they have solar panels on the car also and did not disclose how many watts gained from them.

 

[amberwolf]

If they're talking about range or capacity, the unit needs to include time, usually in hours or h, so kWh, or Wh, etc.

If they're talking about power (not how long it will last or how far it will go), that's just watts, no time unit, so kW or W.


So W / kW / etc without an "h" is a very very different thing than with the h (kWh / Wh etc).


If you don't distinguish between them, the wrong information is conveyed.

 

[Hillhater]

From the article…

During this record, the energy consumption was just 3.8 kWh/100km

….and the distance was 1000km
..average speed 85km/h
So 38kWh total energy used was correct.

UNSW Sydney’s student-built solar-powered car averaged nearly 85km/h over 12 hours to set Guinness World Record with just eight minutes to spare.

Record for the ‘Fastest EV over 1000km on a single charge'. This is the record they broke can not find the time for the last record.
