Vehicle Battery Save Control for Known Extended Parking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicles do not efficiently manage battery power in known extended parking locations, leading to unnecessary battery drain and reduced state of charge.
Innovation Solution
A vehicle system that enters a battery save mode when parked in known extended parking locations, using a controller to determine the location via GPS and implement power-saving measures after a shorter time period than conventional systems.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the vehicle enters battery save mode after a long parking duration, then battery state of charge is preserved, but the vehicle cannot provide necessary functions during extended parking
Solution Approach 1:
The system performs preliminary identification of extended parking locations using GPS and historical parking data before the vehicle actually parks. When the vehicle enters a predefined extended parking location, the controller proactively commands battery save mode after a short time period, preserving battery charge before it would be depleted by conventional timing-based systems.
Solution Approach 2:
The system continuously monitors the vehicle's location via GPS and compares it against stored extended parking location data. This feedback mechanism allows the controller to detect when the vehicle is parked in a known extended parking location and automatically adjust power management strategy, switching to battery save mode appropriate timing based on location rather than arbitrary time delays.
2Use of energy by moving object
If the vehicle uses conventional time-based battery save mode, then implementation is simple, but battery charge is not optimized in known extended parking locations
Solution Approach 1:
The controller performs multiple functions: it manages battery save mode activation, stores and retrieves extended parking location data, and processes GPS location information. By integrating these functions into a single control unit, the system achieves sophisticated power management without adding separate dedicated hardware components for each function.
Solution Approach 2:
The system automatically identifies extended parking locations and manages battery save mode without requiring user intervention. The controller uses GPS data and historical parking patterns to self-determine when and where to activate battery save mode, eliminating the need for manual user input or complex external systems.
3Use of energy by moving object
If the vehicle enters battery save mode immediately upon parking, then battery charge is maximized, but necessary post-parking functions are interrupted
Solution Approach 1:
The system applies different power management strategies based on location quality. When the vehicle is in a predefined extended parking location, the controller commands battery save mode after a short time period (e.g., 5 minutes). For other locations, the system uses a longer default time period, providing a graduated approach that tailors battery save activation to the specific parking context.

AI summary
The techniques described herein relate to a motor vehicle, including: a battery pack electrically connected to an electric machine and a plurality of electrical loads, wherein the motor vehicle is operable in a full power mode in which power can flow from the battery pack to the electric machine and each of the plurality of electrical loads, and a battery save mode in which a flow of power is prevented between the battery pack and either or both of the electric machine or at least some of the plurality of electrical loads; and a controller configured to command the motor vehicle to operate in the battery save mode if the motor vehicle has been parked in a known extended parking location for a first time period, or if the motor vehicle has been parked in a location other than a known extended parking location for a second time period longer than the first time period.
