Enzymes differ from most other catalysts by being much more specific. Enzyme activity can be affected by other molecules: inhibitors are molecules that decrease enzyme activity, and activators are molecules that increase activity.
This fact sheet briefly discusses several load estimation tech-. niques. Reasons to Determine Motor Loading. Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is. usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of. 5 to 10 hp; peak efficiency is at 7.5 hp. A motor âs efficiency tends to decrease dramatically below. about 50% load. However, the range of good efficiency varies with individual motors and tends to. extend over a broader range for larger motors, as shown in Figure 1.
In June 2006, Tesla Motors reported the Roadster's battery-to-wheel efficiency as 110 WÂ·h/km (17.7 kWÂ·h/100 mi) on an unspecified driving cycleâeither a constant 60 mph (97 km/h)) or SAE J1634 testâand stated a charging efficiency of 86% for an overall plug-to-wheel efficiency of 128 WÂ·h/km (20.5 kWÂ·h/100 mi).he Roadster was the first production automobile to use lithium-ion battery cells and the first production BEV (all-electric) to travel more than 200 miles (320 km) per charge.
