Abstract
The present disclosure provides a vibration damping mounting system to mount a batter pack module to a chassis of a vehicle including a top mount coupled to the battery pack module; a lower mount coupled to at least one of a mounting brace on a back panel of the battery pack module and an underside of the battery pack module; and a vibration damping element coupled to the lower mount. The vibration damping element may be at least one of a rubber damper, a spring, a torsion bar, and an air bag damper. The vibration damping element may be controlled by passive or active damping.
Claims25
A vibration damping mounting system configured to mount a battery pack module to a chassis of a vehicle, comprising:
- a top mount coupled to the battery pack module;
- a lower mount coupled to at least one of a mounting brace on a back panel of the battery pack module and an underside of the battery pack module;
- and
- a vibration damping element coupled to the lower mount.
A vibration damping mounting system configured to mount a battery pack module to a chassis of a vehicle, comprising:
- a top mount coupled to the battery pack module;
- a lower mount coupled to at least one of a mounting brace on a back panel of the battery pack module and an underside of the battery pack module;
- a vibration damping element coupled to the lower mount;
- and
- an accelerometer module, the accelerometer module comprising:
- an accelerometer configured to determine forces of acceleration on the battery pack module about 6 degrees of freedom on an X, Y and Z axis;
- an actuator configured to increase or decrease a damping rate of the vibration damping element;
- and
- a control unit configured to receive signals from the accelerometer and transmit a command to the actuator.
A method of controlling a vibration damping system of a battery pack module using live active damping, comprising:
- transmitting an accelerometer signal from an accelerometer to a control unit;
- wherein the accelerometer transmits a signal indicating vibration along 6 degrees of freedom on an X, Y, and Z axis;
- processing the accelerometer signal from the accelerometer using the control unit to determine how much vibration damping is necessary to dampen the vibration of the battery pack module;
- transmitting a damping rate signal from the control unit to an actuator;
- and
- adjusting a damping rate of a vibration damping element by actuating the actuator such that the damping rate of the vibration damping element damps the vibration of the battery pack module.
