Definitions

  • the invention relates to an adapter for an exchangeable battery pack of a battery-operated electrical device or for a charger suitable for charging the exchangeable battery pack, according to the preamble of independent claim 1.
  • the object of the invention is to use a commercially available exchangeable battery pack for a battery-operated electrical device as an energy source for convenient, wireless charging of an energy receiver, in particular a mobile phone or a wearable.
  • the invention relates to an adapter for an exchangeable battery pack of a battery-operated electrical device or for a charger suitable for charging the exchangeable battery pack.
  • the adapter For energy transmission, the adapter has an electromechanical interface with electrical contacts, via which it can be releasably connected to an electromechanical interface of the exchangeable battery pack or the charger.
  • the adapter has a wireless interface for transmitting the energy provided by the replaceable battery pack or the charger to an energy receiver.
  • a commercially available exchangeable battery pack can be used with particular advantage for the wireless charging of a smartphone or a wearable, for example. This is particularly helpful in situations where no other energy sources are available for charging a discharging energy receiver designed as a smartphone, wearable or the like.
  • a battery-operated electrical device in the context of the invention is to be understood in particular as a power tool.
  • the power tool can be designed both as a hand-held power tool and as a stationary power tool.
  • Typical power tools in this context are handheld or stationary drills, screwdrivers, percussion drills, hammer drills, planers, angle grinders, orbital sanders, polishing machines, circular saws, table saws, chop saws and jigsaws or the like.
  • measuring devices such as range finders, laser leveling aids, etc. or garden tools such as lawn mowers, grass trimmers, pruning saws or the like can also be used as battery-operated electrical devices.
  • the invention can also be used in connection with exchangeable battery packs for battery-operated household appliances, such as vacuum cleaners, mixers, etc. or for e-bikes, e-scooters, etc.
  • a wireless energy receiver in the context of the invention is to be understood in particular as a wirelessly chargeable mobile radio device or a correspondingly chargeable wearable, such as a smart watch, a fitness band, smart glasses or other battery-powered devices that can be worn on an operator's body.
  • Typical electrical devices that can be operated with exchangeable battery packs are offered in very different performance classes depending on their intended use. For example, there are handheld power tools as well as garden and household appliances in the lower power classes that are operated with 10.8 V (often nominally also referred to as 12 V) or 14.4 V, while in the medium to higher power classes electrical appliances in voltage classes from 18 V, 36 V, 54 V or even 72V can be used.
  • the voltage values result from the wiring (in parallel or in series) of the battery cells used in the exchangeable battery packs.
  • the battery cells are preferably designed as lithium-based battery cells, e.g. Li-Ion, Li-Po, Li-Metal or the like, with a cell voltage of 3.6 V, with a battery cell usually being a cylindrical round cell whose cell poles are at the ends of the Are arranged in a cylindrical shape.
  • the following invention does not depend on the type, design and number of battery cells, but can be used for any exchangeable battery pack.

  • the electromechanical interfaces of a removable battery pack of one voltage class are designed in such a way that they are only compatible with the corresponding interfaces of a battery-operated electrical device of the same voltage or power class.
  • the wireless interface particularly advantageously has a primary coil in order to inductively transmit energy to a secondary coil of the energy receiver. Since inductive energy transmission is used most frequently alongside other wireless forms of energy transmission, e.g. optically or by movement, the adapter according to the invention is as compatible as possible with appropriately equipped energy receivers, especially if the wireless interface is based on the widespread Qi standard for transmission capacities of up to up to 5 watts (Baseline Power Profile) or 15 watts (Extended Power Profile) with transmission frequencies between 87 and 205 kHz and data rates of up to 2 kBit/s.

  • the electromechanical interface is on the bottom of the adapter, the wireless interface is on the top.
  • the top and bottom do not necessarily have to run parallel to one another, but can also have an angle of up to 30°. This is particularly advantageous when the electromechanical interface of the removable battery pack or the charger is not normal to gravity. It is also conceivable that the wireless interface of the adapter can be adjusted by the operator in terms of its angle to the electromechanical interface.
  • energy can also be transmitted in the opposite direction from the wireless interface to the electromechanical interface.

In this way, a particularly compact adapter can be provided that can be easily stowed away.
  • the adapter has a display for signaling the energy transport and/or a direction of the energy transport. An operator can thus immediately see whether energy is being transmitted and, if so, which of the two charging partners is acting as the energy source and which as the energy receiver.
  • the adapter can have a further electromechanical interface, in particular a USB socket, for discharging and/or charging the exchangeable battery pack connected to it.
