Mode of execution

In the following specific description, in order to provide a comprehensive understanding of the present invention, statements many specific details. However, the technical personnel in this field will be understood that the invention can be in the absence of these specific details practice. In other examples, not describe in detail the known method, procedures and assembly, so as not to make this invention obscurities not cleaning.

Known for electric vehicle power source is a lithium battery, the battery has many benefits. However, stored in the lithium battery residual energy in the unit (for example, kilowatthours) specific cost is relatively high. Some aspects of the invention may relate to a method and apparatus for adding supplementary metal air battery extending electric vehicle (for example, electric vehicle) running range of the system, the metal-air battery relative (existing) can charge the main lithium battery for the purposes of the unit energy has a lower specific cost.

When the capacity of the battery drops to the predetermined threshold, for example its full capacity of 70% is below, the metal-air battery can in case of need, such as in driving, to be used for the main re-charging the battery. This arrangement can allow the use of relatively small and relatively inexpensive rechargeable main battery, in order to fully during the average daily driving need to the vehicle power supply, for example in a re-charging point (for example, the user of the home) to the next re-charging the place (for example, his/her work place) between 60 km of driving-range. When the ask for longer running range, can be used in the supplement of the stroke of the metal air cell to rechargeable main re-charging the battery. The stroke of the 1st part can be only by the rechargeable main battery power supply direct to the main the capacity of the battery drops to the predetermined threshold, the stroke of the after part of the 2nd can be will complement the metal air battery activation, in order to mainly re-charging the battery. In the non-limiting exemplary embodiment, in a moving 1st 60 in thousands of meters, vehicle motor can only by the main lithium battery power supply, in other 300 km, the electric motor can consists of a lithium battery power supply, the lithium battery during the journey from the supplementary metal air re-charging the battery.

For storing electrolyte capacity of the liquid storage tank can be mounted in the electric vehicle, to electrolyte is provided to the metal-air battery. Used for making the electrolyte in the accumulator reservoir and circulate between the metal air cell unit can also be assembled in the pump in the electric motor vehicle. In some embodiments, the electrolyte in the reservoir can be in the capacity of 10 liter -1000 L is in the range of, for example, 20 liter -50 L of small electric automobile or 50 - 250 electric public automobile, electric ship or large vehicles, such as ships, aircraft and the like.

This electrolyte capacity can be used as a preserving heat quantity of the heat battery, for example, in order to heat the passenger compartment of the vehicle or the electric vehicle of other components, such as the driver's seat or the main battery (for example, lithium battery). The electrolyte in the reservoir can be heated by the heating element in advance (for example, starting the vehicle front, such as when the vehicle is stopped), the heating element from the external power supply, such as the urban network, power supply. The city power grid in the three power supply - a lithium battery, metal-air battery and the grid is most inexpensive. The heating element can be located at the electrolytic nature pipeline system anywhere in or close to the electrolytic nature pipeline system of any local, for example in the liquid storage tank or close to the accumulator reservoir. In addition or alternatively, the electrolyte can be in the metal-air battery during operation of the metal air cell as in the surface of the metal anode of the exothermic reaction is heated. From the anode oxidation reaction heat is transmitted to the electrolyte. With the proceeding of reaction, the temperature of the electrolyte, in order to make the electrolyte, thus metal-air battery to keep in the working temperature range, it may be necessary to discharge heat from the electrolyte.

Pre-heating of the electrolyte can allow the metal-air battery better operation. Metal-air battery can be in the best condition to be operated, when the temperature of the electrolyte in the battery in the 30 °C -100 °C between. In traditional metal-air battery in operation, occurs in the battery and serve as the exothermic reaction of the function, the electrolyte is heated to the optimum temperature. However, this process will take some time, and in the beginning of the battery operation in to achieve the optimum temperature before, will reduce the cell to produce the quantity required power capacity. Therefore, in some embodiments, in the electrolyte into the battery heating a liquid storage tank in advance of the electrolyte to a desired temperature can lead to allow the air to metal battery under the optimum condition begins to work.

The heated electrolyte from the heat of the heat source can be used for requiring in certain use. For example, from the heat of the heated electrolyte (for example, the surplus heat) can be transmitted to the passenger compartment via the heat exchanger, in order to heat the passenger compartment. This process in cold weather local and/or winter especially beneficial, such as in northern Europe, north America, and Japan. In a traditional electric vehicle, a main electric energy (for example, lithium battery), its relatively expensive, for vehicle travel and comfortable cabin (for example, heating). Therefore according to some embodiments of the present invention, the use of the electrolyte from the heated heat energy can be saved for driving range of the main energy to provide energy.

In addition or in the alternative embodiment, the passenger compartment of the electric automobile or other assembly can be used including for storing heat storage liquid reservoir system heating. Heat storage liquid can be any can in the desired temperature to maintain or preserve the heat of the liquid, such as water, mineral oil, such as potassium hydroxide and sodium hydroxide solution. Heat storage liquid can be stored in fluid pot heating, for example through in fluid pot and located by an external power source to the heating element, the external power source such as a network. In addition or alternatively, can be used from the outside of the vehicle of the heated and liquid of the heated heat storage liquid filling reservoir, for example located in the service station of the heated liquid storage tank. Can use the heat exchanger heat from the heated heat storage liquid and discharges and transmitted to the assembly of the electric vehicle.
