Battery Charge Control for Temperature Actuator Power Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing charge control devices do not limit the electric power consumption of battery temperature control actuators, leading to a decrease in the state of charge (SOC) of vehicles during charging.
Innovation Solution
A charge control device with a controller that limits the electric power consumption of the battery temperature control actuator to equal or less than the output limit of the charging station, thereby preventing excessive power consumption during vehicle charging.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If electric power for battery temperature control is not limited, then battery temperature control performance is improved, but SOC decreases during charging
Solution Approach 1:
The patent changes the power consumption parameter of the battery temperature control actuator by imposing an output limit equal to or less than the charging station's maximum output. This parameter change ensures that temperature control functions are maintained while preventing excessive power consumption that would cause SOC to decrease during charging.
2Temperature
If battery temperature control actuator power is unlimited, then temperature control effectiveness is improved, but charging efficiency deteriorates
Solution Approach 1:
The patent modifies the power consumption parameter of the battery temperature control actuator by setting an output limit. This ensures that the actuator consumes power only within the available charging capacity, preventing it from consuming power that should be allocated to charging, thereby maintaining both temperature control effectiveness and charging efficiency.
3Temperature
If no power limit is imposed on temperature control actuator, then temperature regulation capability is improved, but power allocation efficiency deteriorates
Solution Approach 1:
The patent changes the power consumption parameter of the battery temperature control actuator by imposing an output limit equal to or less than the charging station's maximum output. This ensures optimal power allocation where the temperature control actuator receives only the power available after accounting for charging requirements, preventing energy waste and improving overall power allocation efficiency.
