Peak power output (PPO), also known as "peak work rate" is a common measure of exercise intensity. For example, researchers may ask subjects to complete an incremental exercise test where VO₂max is measured while the person cycles at increasingly difficult power generation levels as measured by a cycle ergometer.

Shift control method, device and vehicle
The application provides a gear shifting control method and device and a vehicle. When a gear shifting instruction of the vehicle is received, the current gear shifting type is determined. If the target motor of the vehicle has a power supplement demand under the current gear shifting type, the target power supply power of the target motor in the power supplement stage is determined based on the power supplement stage corresponding to the current gear shifting type, and the target output power of the power battery to the target motor in the power supplement stage is adjusted based on the target power supply power and the peak power output duration of the power battery. The target power supply power is used to represent the power required by the power battery of the vehicle to provide to the target motor when the power battery operates at the peak power.
