A fob for a passive entry passive start (PEPS) system includes a LF receiver, an UHF transmitter, an UWB transceiver, a primary battery to power the receiver and the transmitter, a rechargeable secondary battery to power the transceiver, and a controller. The controller may cause the primary battery to recharge the secondary battery when the secondary battery has a low charge. The controller may cause the transmitter to transmit an indication to a base station of the PEPS system that the primary battery has a low charge. This indication is to alert a user to replace the primary battery. The controller may cause the transmitter to transmit an indication that the secondary battery is dead when the secondary battery is detected to be dead. This indication is to alert the base station that PEPS communications of the fob will not involve the transceiver.

A power supply control module includes a first sheet portion, a second sheet portion, a wireless communication unit, a switch unit and a controller. The controller configured to cause the switch unit to switch between a closed state and an opened state based on the result of communication performed by the wireless communication unit, the closed state being a state in which a first cell side electrode layer and a terminal side electrode layer are electrically connected to each other and the opened state being a state in which the first cell side electrode layer and the terminal side electrode layer are electrically disconnected from each other.

A portable remote control device such as a key fob includes a motherboard, a battery daughterboard having a battery holder to secure a battery, and an interconnect mounting the battery daughterboard to the motherboard. The battery daughterboard may include a first via and the motherboard may include a second via in which the vias are misaligned with one another. The interconnect includes a first pin inserted through the first via and the second via to mount the battery daughterboard to the motherboard. The first pin has a disjointed configuration over a length of the pin in correspondence with a misalignment of the first via and the second via.

Provided is a power consumption suppressing device for electronic key terminals capable of effectively suppressing electronic key terminal power consumption. An electronic key terminal comprises a charge state detection unit to specify a charging point where a storage battery can be charged. Moreover, the electronic key terminal comprises a power consumption suppression unit to suppress power consumption by the electronic key terminal on the condition of the specified charging point not being contained in an arrival point and a destination of a vehicle.

A portable identification transmitter for a passive access system of a motor vehicle includes an electrical buffer store which is coupled to an LF circuit assembly in order to charge the electrical buffer store via an energy draw from electromagnetic fields coupled in via LF antennas. Also included is an electronic switching device which can decouple a battery from a microcontroller of the passive access system. The microcontroller and the LF circuit assembly are coupled to the buffer store so that when the buffer store is charged beyond a specified charging level, the open electronic switching device can be activated to couple the battery to the microcomputer via the microcontroller while energy is supplied to the microcontroller from the buffer store.

A battery holder includes a terminal component electrically connected to one electrode of a battery and a battery restraining part that is separate from the terminal component. The terminal component includes: a fixed portion fixed to a mounting surface; an arm portion extending from the fixed portion to come into contact with said electrode; and a cutout portion opened toward the battery in said arm portion. The battery restraining part is located between the terminal component and the battery while being received by the cutout portion, in order to accept an impact load from the battery.

A system for transitioning a key fob between a standard operating mode and a battery conserving shipping mode includes a shipping mode controller which detects a vehicle state indicative of a vehicle shipping mode operation having been performed, and causes a shipping mode instruction signal to be sent from a vehicle to the key fob associated with that vehicle instructing the key fob to transition from the standard operating mode to the shipping mode. The vehicle shipping mode operation is an operation which initiates a transition of the vehicle from a standard operating mode to a shipping mode, and serves as a trigger for the shipping mode controller to transmit the shipping mode instruction signal. When in the shipping mode, the key fob may be entirely powered-off or have certain communication-related functions disabled.
