Definitions

  • the invention relates to a vehicle which is driven exclusively by one or more electric motors and which has at least one exchangeable and rechargeable battery for supplying energy to these electric motors.
  • hybrid vehicles which have one or more electric motors in addition to an internal combustion engine.
  • the drive energy is initially applied almost exclusively by the high-torque electric motor when accelerating from a standstill. If the acceleration is still increased or if high speeds are to be achieved, the internal combustion engine is automatically connected, so that the vehicle is driven by both drive motors. In individual cases, especially when driving evenly with only a small load, the electric motor is switched off. For energy supply powerful batteries are needed, which are charged via the intended alternator while driving.
  • such vehicles have a regenerative braking system in which the braking energy - as far as possible - is converted back into electrical energy.
  • the desirable alternative is a purely electric motor-powered vehicle, which can be operated pollutant and emission-free due to the lack of combustion engines.
  • efforts are currently failing because the range of a powered exclusively with an electric motor vehicle is relatively low. A longer range can only be achieved with an increase in battery capacity reach, which loads the vehicle with additional weight and occupy further vehicle space.
  • the vehicle according to claim 1 which is characterized according to the invention in that the battery has an integrated data acquisition and data storage device, which detects the current state of charge and / or the time of the last battery change and / or total or since the last battery change charge cycles ,
  • the aforementioned equipment of the battery results in the result that the battery can be replaced without detriment to the vehicle user and replaced by a charged battery.
  • the data acquisition and storage device allows immediate control of which energy has actually been consumed.
  • the vehicle owner or vehicle user expects only the energy removed from the battery with the energy supplier, who may be a gas station, for example. As is currently practiced in propane gas bottles, billing can thus be carried out in a consumption-oriented manner.
  • Changing the battery can be greatly facilitated by their location and their attachment to or in the vehicle.
  • the battery change should be possible without the driver having to leave the vehicle.
  • the removed battery can then be recharged in a battery-saving manner and installed in another vehicle.
  • the billing the vehicle operator receives is consumption-based, with the respective data collection and storage facilities of the battery, combined with battery coding, providing sufficient information as to the age of the battery.
  • the change of a battery to another vehicle is also advantageous because in this way a one-sided load condition, as it is often encountered in pure city riders or frequent travelers, is avoided. Instead, the batteries are subjected to a mixed operation by correspondingly many vehicle changes, which has an overall lifetime-increasing effect.
  • the integrated data acquisition and storage allows a control system at any time to detect the remaining charge capacity of the battery, so that it is up to the vehicle user to make a recharge or postpone.
  • This cheap electricity tariffs can be exploited, such that - except for exceptional cases - always only as much charge is returned to the battery, as is actually required for the next journey section or the next drive sections, but in principle a recharge takes place only if favorable electricity tariff can be exploited.
  • the battery consists of several individual cells with respective outputs, which are automatically connected in series only in case of need, namely in the connected state in the vehicle or in a charging station by a required voltage of 300 V to 600 V, preferably 500 V to 600 V, to tap. This has the advantage that the extremely high voltage is applied only when needed, and thus personal injury to short circuits of stored stored batteries are excluded.
  • the battery or each battery is mounted on the underside of the vehicle, preferably below a designed as a fire wall (firewall) floor platform and / or between the vehicle axles.
  • a designed as a fire wall (firewall) floor platform and / or between the vehicle axles Such attachment has the particular advantage that the center of gravity of the vehicle is placed as low as possible.
  • two or more batteries can be arranged, approximately to increase the range accordingly.
  • the batteries used should be as flat as possible, whereas the length and width can be adjusted according to the available length / width ratio of the vehicle type adapted.
  • the battery has a tapered to the top, preferably conical shape, which is inserted into a correspondingly adapted corresponding cavity on the underside of the vehicle from below or from the side, preferably the battery side walls abut under slight compressive stress on the vehicle cavity side walls so that the vehicle floor rigidity is thereby increased.
  • the conical shape assists in automatically inserting the battery into the corresponding vehicle cavity so that any misdirection of the vehicle relative to the reciprocator with which the battery is raised into the cavity can be compensated.
  • an elastic seal is provided, by which an ingress of dirt or moisture is prevented at the terminal poles between the battery and the vehicle. In addition, this seal can also contact Avoid noise between the battery and the battery box, but at least minimize it considerably.
  • an on-board lifting and quick release device is also provided, which is designed to release the battery or batteries, to their storage, to receive a new battery and to attach it to the vehicle.
  • this may be spindle-guided brackets that are driven either by hand or by means of an emergency generator.
  • a vehicle-integrated data acquisition and storage device is provided with a data input which receives via existing lines or wirelessly transmitted signals relating to the energy taken in the battery replaced, the usage time, any charge cycles and which from Data collection and storage device of the battery are read before the exchange or sent from here, the automation of a billing system is largely possible. All billing-related data, in particular the energy consumed, are recorded both at the place where the deflated battery is left for recharging and in the vehicle, so that the driver receives control of the energy consumption or the amount to be paid there.
  • the battery and the charging and power electronics can also be designed for feeding power into a pipeline network.
  • the battery can thus also be used to supply other energy sources that are connected to the line network.
  • a preferred use is as an emergency power supply to selected power consumers such as hospitals, elevators, traffic lights or the like.
  • Private or only slightly used vehicles have significantly longer lives than periods of use.
  • vehicle service life coincides with the periods when there is a high electricity demand, on which the network must be designed.
  • peak currents occur during lunch time when energy is needed for cooking in many households.
  • the present invention makes it possible that energy previously fed into the battery of the vehicle is taken from the batteries of the vehicles except for a rest still required for driving.
  • the vehicle owner can use this recovered energy privately or feed it into the grid as usable electricity. In this way, a large amount of battery capacity can be harnessed so that the electricity supplier can reduce its capacity designed for peak times accordingly. This benefits both the generators and the electric vehicle owners, who measure the amount of energy taken from the battery by means of existing electricity meters and are reimbursed for this an appropriate compensation.
  • the vehicle has a device with which the current electricity price of the energy supplier for charging the battery and / or for feeding it back into the network is detected.
  • electricity prices vary considerably, including price fluctuations during a single day.
  • the mentioned device can be used so that the battery is not only recharged at fixed times or when a residual capacity has been exceeded, but that used for charging low-cost periods and for energy recovery such periods in which for the recycled energy is reimbursed in each case a high electricity price.
  • the vehicle has a controllable device for setting an upper current price threshold, is exceeded when power is fed into the network of a power supplier and / or for setting a lower electricity price threshold, below which power from the network to Charging the battery is removed.

Another advantage results from the fact that the recharging of the batteries at the service stations can be done at times when the price of electricity is low. If energy consumption is billed as a function of the temporarily current demand in the course of a power exchange, a favorable electricity price based on low consumption can thus be used effectively.
