  • Typical tire monitoring sensors such as tire pressure monitoring sensors, utilize a cylindrical com cell battery that is conventionally based on Lithium Manganese Dioxide (LiMnO2) technology. While there have been improvements, the fundamental underlying technology 7 has not changed significantly and hosts a number of disadvantages.
  • the coin cell batteries have a liquid-based electrolyte, which means that they must be mounted in a plane that is substantially parallel to the drop center of the wheel rim.
  • a coin cell battery must also be tagged in order for the electrical connection to be made between the coin cell and the printed circuit board.
  • These coin cells are also shipped in trays and require bespoke equipment to allow them to be soldered into the tire monitoring sensor housing.
  • Lithium Manganese Dioxide cells that are conventionally used cannot be surfaced mounted to a printed circuit board (PCB) because they cannot tolerate temperature excursions above 150° C. These cells have a liquid electrolyte which means that they must be orientated in the product in a particular manner to allow homogenous discharge at high speed. Lithium Manganese Dioxide cells have a finite lifetime and cannot be recharged. These cells have a high self-discharge, especially at high temperatures. This effectively reduces the capacity available in the cell to support the power requirements of the application.
  • PCB printed circuit board
  • Lithium coin cells require specialized and expensive equipment to allow soldering between the PCB and the battery tag. This operation can lead to solder balls and short circuits.
  • Coin cells require either expensive tags or battery holders to allow the electrical connection to be made between the cell and the PCB.
  • Conventional lithium coin cells may not be able to supply the energy to enable the implementation of advanced features. These cells are made in very high volumes on highly automated production lines. Coin cells do not have form factors other than a disk-shape. In other words, the form factors of these cells are very inflexible.

  • the tire monitoring sensor includes a solid-state battery that is surface-mounted directly on a PCB and does not include any battery tags. Further, because the solid-state battery does not have a liquid electrolyte, there is no requirement for a specific orientation of the battery.

  • Examples of the tire monitoring sensor include batteries of various form factor shapes.
  • the battery form factor can be selected to conform to the profile of the PCB. This allows more freedom to design the tire monitoring sensor in a size and weight optimized manner. This is particularly important in applications where the tire monitoring sensor is mounted to the tire.
