Definitions
- the invention relates to a device for increasing the starting safety of a vehicle with an internal combustion engine, which is started with a powered by a liquid electrolyte battery starter.
- lead-acid batteries are preferably used for operating the starter, which are known to have a high weight because of the lead content.
- the endeavor of the vehicle industry for lightweight construction also relates to the saving of battery weight.
- the demand for higher battery power increases, since in addition to the conventional energy for starting z.
- servo motors for adjusting the seats or for electrically heating the seats is needed.
- Battery power is understood below to mean the capacity of the battery as well as its ability to supply power or to draw power. Battery performance is affected by various factors known to those skilled in the art.
- the object of the invention is to provide a device which increases the performance of the battery and extends its life, whereby the starting safety of the internal combustion engine is increased.
- a liquid electrolyte battery comprising: an electrically operated device for mixing the liquid electrolyte, wherein here any type of device is included, which is electrically driven or operated, such as.
- an electrically operated device for mixing the liquid electrolyte wherein here any type of device is included, which is electrically driven or operated, such as.
- various pumps magnetic stirring systems or thermal mixing devices that cause a mixing of the electrolyte by means of a heater.
- tilting devices with the help of a movably mounted in the vehicle, but attached battery, can be tilted back and forth.
- the battery is equipped with a known from the prior art hydrodynamic mixing device, which causes an effective mixing while driving - and consequently also a Blending in a stationary vehicle allows when the battery is moved by means of a moving device.
- At least one temperature sensor for measuring the battery temperature and at least one voltage sensor for measuring the battery voltage are provided.
- Such sensor arrangements of starter batteries are known from the prior art and therefore need not be explained in more detail to the person skilled in the art.
- a first memory circuit for storing at least the battery temperature and the battery voltage over time
- a second memory circuit are stored in the temperature-voltage value tables that contain relationships between the battery temperature and battery voltage, from which the state of charge and the aging state of wells - Sigelektrolyt battery can be removed.
- These temperature-voltage tables are to be made for different battery types or are available to the manufacturers of modern batteries as long-term test results.
- a first comparison and evaluation circuit determines the current state of charge and aging of the battery at least from the temperature and voltage values measured on the battery over time and by comparison with the comparison values taken from the second memory circuit.
- a third memory circuit in which are stored skillsmi- tion panels that provide the required state of loading and aging of the battery and the current battery temperature a minimum sayinschaltdauer the mixing device before Hochstrom redesigner be turned on to prepare and carry out the starting of the internal combustion engine It also takes into account how long the high-current consumers would have to be turned on at the current temperature, the life of the vehicle and other relevant operating conditions in order to safely start the internal combustion engine. Furthermore, a recognition device is provided by means of which it can be recognized with high probability that the internal combustion engine is to be started. This recognition device is required because today's driver is used to starting the engine immediately after the ignition key or start button is pressed. A delay in starting is perceived as a limited performance of the vehicle and is therefore avoided by the vehicle manufacturer, as far as it is technically possible and reasonable.
- the detection device outputs a signal for turning on the mixing device when the start of the internal combustion engine is likely to be intended.
- the recognition device is connected to the door lock of the driver's door, since the probability of an intended trip is high when the driver's door is opened. It is clear to those skilled in the art that the recognition device is switched so that z. B. after reopening the driver's door after driving - because the driver forgot something in the vehicle - the mixing must not be performed.
- the detection device is connected by circuitry with the remote control of the door lock.
- the aid of the invention to give the driver the feeling of unrestricted driving readiness of his vehicle by means of technical means and at the same time to reduce the acidification of the battery to a predeterminable minimum amount, thereby prolonging the service life of the battery.
- the mixture of the electrolyte should preferably also be maintained during starting, since in this phase the battery is heavily loaded by the high-current consumers and the mixing of the electrolyte promotes the current output and lowers the wear of the battery.
- Fig. 1 shows the functional flow chart of the device according to the invention.
- a first functional step it is determined which high-current consumers must be switched on at the intended start and for how long before the internal combustion engine drives the generator, ie how much the battery is likely to be loaded.
- a minimum mixing time of the electrolyte is determined in a second functional step, i. H. a period of time that is mixed but not yet started.
- the mixing of the electrolyte is carried out.
