Abstract
The invention relates to a management system and method for the heat treatment of at least one element of a drive train of an electric or hybrid motor vehicle so as to optimize the performance of the vehicle for intensive use being carried out or planned.
Claims13
A method for managing heat treatment of at least one element of an electric drive train of an electric or hybrid vehicle equipped with at least one electric battery module and at least one heat treatment system of at least one of the elements of the electric drive train, the method comprising:
- detecting an activation, manual or automatic, of an intensive use of the vehicle currently being executed or planned, the intensive use being a use of the vehicle during driving that requires performance of the vehicle that exceeds a normal use over a specific period of time;
- and
- when the intensive use is detected:
- determining at least one temperature of the at least one element of the electric drive train and comparing the at least one temperature with at least one target optimal operating temperature specific to the at least one element of the electric drive train so as to detect a deviation relative to the at least one target temperature;
- and
- heat treating the at least one element of the electric drive train when the deviation is detected relative to the at least one target temperature specific to the at least one element of the drive train.
A hybrid or electric motor vehicle comprising:
- at least one electric battery module configured to power at least one element of an electric drive train of the vehicle and at least one heat treatment system of said at least one element;
- and
- a management system comprising circuitry configured to:
- detect an activation, manual or automatic, of an intensive use of the hybrid or electric motor vehicle currently being executed or planned, the intensive use being a use of the vehicle during driving that requires performance of the vehicle that exceeds a normal use over a specific period of time;
- and
- when the intensive use is detected:
- determining at least one temperature of the at least one element of the electric drive train and comparing the at least one temperature with at least one target optimal operating temperature specific to the at least one element of the electric drive train so as to detect a deviation relative to the at least one target temperature;
- and
- heat treating the at least one element of the electric drive train when the deviation is detected relative to the at least one target temperature specific to the at least one element of the drive train.
A non-transitory computer readable medium storing a program that, when executed by a computer, causes the computer to execute:
- detecting an activation, manual or automatic, of an intensive use of a hybrid or electric motor vehicle currently being executed or planned, the vehicle including an electric drive train including at least one electric battery module and at least one heat treatment system, and the intensive use being a use of the vehicle during driving that requires performance of the vehicle that exceeds a normal use over a specific period of time;
- and
- when the intensive use is detected:
- determining at least one temperature of at least one element of the electric drive train and comparing the at least one temperature with at least one target optimal operating temperature specific to the at least one element of the electric drive train so as to detect a deviation relative to the at least one target temperature;
- and
- heat treating the at least one element of the electric drive train when the deviation is detected relative to the at least one target temperature specific to the at least one element of the drive train.
