It does this by using a "regenerative braking" system. That is, instead of just using the brakes to stop the car, the electric motor that drives the hybrid can also slow the car. In this mode, the electric motor acts as a generator and charges the batteries while the car is slowing ...
What is a battery’s state of charge (SoC)? What is a battery's cyclic life? Lithium-ion vs. lead-acid batteries Battery temperature: Why does it matter? Which battery is the right option for you? Compare storage options on EnergySage We’ve all experienced that dread: Watching...
As you close in on O% you’re running on empty — then you’re out of gas. Depth of Discharge (DoD) measures a battery’s state of charge in reverse. The formula is DoD = 1 – SoC. In other words, if you only have 10% of the battery’s total storage capacity left, the DoD...
