9.6: Electrical Energy and Power

Electric motors have a reasonably high efficiency. A 100-hp motor can have an efficiency of 90% and a 1-hp motor can have an efficiency of 80%. Why is it important to use high-performance motors? Answer. Even though electric motors are highly efficient 10–20% of the power consumed is wasted, not being used for doing useful work.

The High-power Lithium-ion

Spinel has an inherently high thermal stability and needs less safety circuitry than a cobalt system.Low internal cell resistance is the key to high rate capability. This characteristic benefits fast-charging and high-current discharging. A spinel-based lithium-ion in an 18650 cell can be discharged at 20-30A with marginal heat build-up.

What is a safe max. discharge rate for a 12V lead acid battery?

Max Discharge Current (7 Min.) = 7.5 A; Max Short-Duration Discharge Current (10 Sec.) = 25.0 A; This means you should expect, at a discharge rate of 2.2 A, that the battery would have a nominal capacity (down to 9 V) between 1.13 Ah and 1.5 Ah, giving you between 15 minutes and 1 hour runtime.
