Re: [EVDL] Magnetic Shock Absorber & EV
<<< Force of air drag times distance equals energy required
.5*Cd*A*rho*v^2*d
The lowest Cd I found for a Dodge Caravan was .35, and the lowest area
was 30 square feet.
.5*.35*30ft^2*1.3kg/m^3*(55mph)^2*150miles
25.7 kWh >>>
Rolling resistance with half a ton of lead is nearly that much, unless
you do some very thorough optimizing.
<<< Energy in 16 T-105's (using 6 hour rate even though he's at 3 hour
rate, ignoring Peukert's effect):
16*6V*205Ah
19.7 kWh >>>
About 5% less at 3hr rate.
