Electric Vehicle Range Estimation via Temperature Control Energy Segmentation

The temperature control energy consumption is segmented into two distinct phases: transient phase energy consumption (determined from signed temperature difference between actual and target temperature) and stationary phase energy consumption (determined from ambient temperature). This segmentation allows the complex temperature control process to be broken down into manageable components that can be calculated using pre-stored typical energy consumption values, thereby improving accuracy without excessive computational complexity

Typical temperature control energy consumptions for both transient and stationary phases are pre-stored in the system based on historical data and environmental conditions. When estimating range, the system directly retrieves these pre-stored values based on current temperature and ambient conditions, avoiding the need for real-time complex thermal simulations while maintaining high accuracy in energy consumption estimation

The system dynamically identifies whether the vehicle is in transient or stationary phase based on real-time temperature conditions. During transient phase (when actual temperature differs significantly from target temperature), the system uses pre-stored transient energy consumption values. When the system reaches target temperature and maintains it, it switches to using pre-stored stationary phase energy consumption values. This dynamic adaptation simplifies the control logic while improving estimation accuracy

The system changes the parameter used for energy consumption estimation based on the operational phase: during transient phase, energy consumption is determined as a function of signed temperature difference; during stationary phase, energy consumption is determined as a function of ambient temperature. This parameter change approach allows accurate estimation without requiring complex real-time calculations, as each phase has its own simplified estimation model
