Definitions

  • the invention relates to a device of the type specified in the preamble of claim 1.
  • Charging and discharging the batteries of vehicles mostly takes place with energy suppliers and consumers, whose energy supply or energy consumption changes frequently.
  • electromagnets with the functions “carry” and “guide” are considered as consumers, and on the other hand conventional devices such as air conditioning systems, lighting and other electrical devices.
  • the electrical energy required for this is generated with the help of linear generators and voltage converters connected to them, the linear generators being built into the supporting magnets and using the z. B. trained as long stator linear motors drives the magnetic levitation vehicle.
  • the vehicle electrical system is supplied with a DC voltage of approximately 484 V, which is provided by the voltage converters, which are generally designed as step-up converters for this purpose.
  • linear generators of this type can only provide the required operating voltage at speeds of around 100 km / h and more, the Vehicles carry backup batteries that supplement or replace the linear generators at slower speeds. If the speed of the vehicles is sufficiently high again at a later point in time, the linear generators or voltage converters not only supply the vehicle electrical system again, but also charge the batteries.
  • the charging of the batteries has been done with two voltage levels.
  • a high voltage serves z. B. for rapid recharging (rapid charging) of a battery until the amount of charge removed is equalized, d. H. until a full charge is reached.
  • a low voltage is aimed at maintaining the charge of the fully charged battery during those periods at which the linear generators are fully effective and at most a certain self-discharge of the batteries can take place. Both voltages are constant and independent of the operating conditions of the batteries. When choosing the two voltage levels, a compromise must be made, for. B. between the behavior of a battery at high and low temperatures or other operating conditions.
  • the batteries are not optimally charged at low operating temperatures and therefore have a lower usable capacity when fully charged than the nominal capacity, while at high operating temperatures the charging voltage must be kept so low that overcharging is avoided an undesirably high water consumption and the resulting temperature increases, undesired gassing effects or the like.
  • the invention is therefore based on the technical problem of designing the device of the type described at the outset in such a way that overcharging of the batteries is reliably avoided and batteries can be operated with voltages which are favorable for rapid charging and charge maintenance, regardless of the temperature and other influences, without this Discharge behavior is impaired.
  • the device with simple design means and with security required for being carried in vehicles.
  • the invention has the advantage that, on the one hand, the battery can be charged quickly with the full voltage of the voltage transformers and the resulting charging current, while on the other hand only a small charge current serving to maintain the charge flows in a phase following the full charge achieved thereby.
  • the switching element that enables rapid charging is switched back to an open position in good time so that it does not hinder its discharge if the battery becomes necessary.
  • an embodiment of the invention is shown in connection with an on-board network common in magnetic levitation vehicles.
  • a plurality of here eight linear generators 1 cooperate in a known manner with a long stator laid along the travel path and in this case is provided with windings inserted into the pole faces of the supporting magnets.
  • a voltage converter 2 in the form of a step-up converter is connected to each of the linear generators, which converts the alternating voltage of z. B. 300 V in a DC voltage of z. B. converts 484 V.
  • the voltage converters 2 also have conventional regulators 4, which serve the purpose of supplying a constant DC voltage at the outputs of the voltage converters 2.
  • Each voltage converter 2 or the sum of all voltage converters 2 simultaneously represents an energy supplier for the vehicle in which it is installed.
  • the eight voltage converters 2 here are electrically connected in parallel to an electrical system which has a positive line 5 and a ground line 6.
  • the positive pole of a battery 7 is also connected to the positive line 5, the negative pole of which lies on the ground line 6.
  • the first means for fast charging contains an electronically controllable, e.g. B. designed as a contactor switching element 9, the z. B. is connected in a line 10, the positive pole of the
  • the second charge maintenance means is parallel to the switching element 9 and contains an ohmic resistor 11.
  • the device described is operated in such a way that during normal operation of the vehicle electrical system, ie when the voltage converter 2 te energy supplier provides a sufficient on-board voltage between lines 5 and 6, the switching element 9 is in an open position so that it is not electrically conductive and therefore the resistor 11 a possible charging current through the battery 7 to a preselected small value of z. B. 100 mA is limited and at the same time the charging voltage lying on the battery 7 is reduced.
  • the maintenance current is also dimensioned so low that it just compensates for a self-discharge of the battery 7, the size of which is known or can be easily determined.
  • the resistance 11 lying in series with the battery 7 has the consequence that it automatically reduces the voltage on the battery 7 when the current increases and thus represents a further protection against overcharging. If, on the other hand, the battery 7 is completely or partially discharged after a prolonged discharge of the battery 7, that is to say, for example, the magnetic levitation vehicle has come to a standstill or slow travel, then the switching element 9 is switched on and set to an electrical current-conducting state. If the voltage converters 2 then again supply sufficient energy, the battery 7 can be charged quickly immediately through the switching element 9, which electrically represents a short circuit in the line 10 parallel to the resistor 11.
  • the switching element 9 does not have to be switched under load or only with a low current flow, it is expedient to switch over to the conductive state during phases during which the discharge current of the battery 7 is comparatively small. In contrast, the switching element is switched off when the battery 7 is flowed through by the resistor 11 only by a small charge maintenance current.

  • the switching element 9 If the voltage converters 2 supply a sufficiently high voltage between the lines 5 and 6, the switching element 9 is in the non-conductive state, while the diode 12 blocks a current flow in the direction of the battery 7. Therefore, only a small charge maintenance current determined by the resistor 11 can flow through the battery 7. The rest of the energy supplied by the voltage converters 2 is supplied to the consumers 8.
