Can they precharge the battery before the race? Also is the size of the battery mandated or are the manufacturers picking an optimal size?

Are you sure you want all this? :D

Maximum storage = 60kw
400kj per lap allowed to be used
0-100% power in ~50ms
Won't activate under 160kph as the system is traction limited

Acts like a form of ABS for recharging - allows later breaking into the corners - around 4m later

Will it increase overtaking? No - Will only help a faster car overtake a slower one.
Worth around 0.3-0.45 per lap depending on circuit.
Is it green? No.
 
Woah! Rosberg suddenly got a nice lap in there!

I think the batteries ahve to be charged on the outlap to be used off the grid... (id assume so as you shouldnt be plugging them into the wall in the pits before going out)

I thought no, as nobody wants a grid of highly charged cars sitting about waiting to electrocute celebreties, but Davison suggested in his commentary that KERS would give a good boost off the line.... so maybe some heavy breaking on the out lap and warmup lap could fully charge the batteries.

yeh thats what i heard to, i think KERS is a bit of an advantage to those who can afford it :rolleyes:

I think from what someone (it might've been CSl), KERS can be fully recharged over only a few corners. Obviously this will become clear as we go through the races, but I think you could easily charge up the KERS device on a relaxed warm-up lap.

So you can't shoot off the starting line? Because won't you get higher torque with kers off the line?
 
But if it cant be used under 160kph then it cant be used off the line.

And MY GOD have they been expensive! Really big costs for a formula that keeps telling us its cutting its costs!

Precicely - but as a F1 car will get to 160kph from a standing start in under ~3 seconds then it can still be used at the start.

I'm more worried about the flywheel systems. They've only been crash tested to 20g. Kubica's crash was 75g - record F1 crash is 180g

What happens if a 65000rpm flywheel comes lose?
 
I am certainly impressed with Heikki. He is using the hard tyres and is able to mix it with the BrawnGP cars.

Hamilton is pushing hard (he has already had 2 offs, so far) and is currently in 15th fastest.

Heikki is definitely making better use of the McLaren so far.
 
I keep hearing what sounds like a little down-up-down shift at the end of straights? Drivers missing gears or the KERS cutting in/out?
