The continuous power of an e-axle refers to the constant power output that an electric axle system can deliver over an extended period without overheating or causing damage to its components. An e-axle typically integrates various components essential for an electric vehicle's propulsion into a single unit, including the electric motors, power electronics, gearbox, etc. It indicates e-axle's capability to provide consistent power output for driving the vehicle under normal operating conditions without exceeding its thermal limits

Manufacturers and designers determine the continuous power rating based on several factors, including:

  • Thermal management: Ensuring that the e-axle's components, especially the electric motor and power electronics, can effectively dissipate heat during continuous operation to prevent overheating.
  • Material selection and design: Using materials and construction methods that enable efficient heat dissipation and maintain operational integrity under sustained power delivery.
  • Duty cycle and operating conditions: Analyzing the typical usage patterns and environmental conditions to establish the power demands over time and ensuring the e-axle can handle these demands without compromising performance.
