A battery heating device includes a temperature sensor and at least one heating element in a liquid and acid-proof arrangement inside the battery. The heating element is a power transistor secured to a cooling plate which is powered by the battery, the emitter of the power transistor being powered by a temperature control circuit when the battery temperature falls below a predetermined reference temperature and the battery voltage is higher than a lower threshold and lower than a higher threshold. A trigger circuit responds to a rise in battery voltage after the current in a load having a high current consumption is switched off. The trigger circuit actuates a timer circuit which conductively controls the power transistor for a set time if the battery voltage is under or at the lower threshold.
A device for improving the current output to a load of a chargeable battery at low outside temperatures, comprising a container for a plurality of batteries having walls, said walls including at least one wall which contains first wall segments spaced apart from each other, said first wall segments being hollow and subjected to overpressure and extending over an entire thickness of said at least one wall, said first wall segments having spaces therebetween;
A device for improving the current output to a load of a chargeable battery at low outside temperatures, comprising a container for a plurality of batteries having walls, said walls including at least one wall which contains two identically designed halves disposed on an inside and an outside, respectively, and having hollow first wall segments which are subjected to overpressure and are disposed respectively spaced apart;
A device for improving the current output to a load of a chargeable battery at low outside temperatures, comprising at least one battery disposed in a housing having a wall with two plates having beads on an inside thereof, said beads being disposed offset from each other on both plates;
A device for improving the current output to a load of a chargeable battery having at least one cell, comprising a U-shaped pipe disposed in said at least one cell of said battery, said U-shaped pipe having a bend which is located near the bottom of said at least one cell and has flow-through openings, said U-shaped pipe having legs which have openings, said openings of said legs of said U-shaped pipe being located close to an upper end of said at least one cell, said device further comprising means for generating a flow in said U-shaped pipe.
A device for improving the current output to a load of a chargeable battery at low outside temperatures, comprising:
