Abstract
The invention relates to a safety design power supply which comprises a lithium battery pack. The positive pole end of the lithium battery pack is connected with one end of a main load and one end of an auxiliary load. The negative pole end of the lithium battery pack is connected with the other end of the main load through a first protection circuit and connected with the other end of the auxiliary load through a restorable current-limiting temperature control element and a second protection circuit. The safety design power supply has the advantages of being high in use safety performance and reducing safety threats to vehicle-mounted staff.
Description
Technical field
The present invention relates to a kind of safety Design power supply.
Background technology
Lithium ion battery is a brand-new battery types that just grows up in nearly 30 years, and it has, and specific energy is high, and specific power is large, have extended cycle life, and the low and environmentally safe of self-discharge rate, this is that other traditional storage battery are incomparable.Therefore expand to rapidly real-life every field.But this kind battery has the some shortcomings part.At first it has extremely strict requirement to terminal point and the charging method of charging and discharging, if indiscriminate operation does not only reach desirable premium properties, also can reduce its useful life.In addition, it uses organic electrolyte, and high energy density is arranged again, and abuse also may bring blast and danger on fire.In order to prevent abuse, ensure safety, increase the service life, general lithium ion battery all is equipped with a complexity and accurate protective circuit, and charging process is managed, and can also eliminate the problems such as accidental short circuit.
Protective circuit is self-evident to the protective effect of the use safety of battery.But in using, certain can bring beyond thought trouble to the user.As using in vehicle; an automobile of normally running at high speed; circuit has occurred a bit unexpected suddenly; the protective circuit action; all electric current outputs have been cut off; this car has not only lost power so, has lost simultaneously the signal lamp power supply and the operating power such as open the door, and this will be a kind of very large danger to on-board crew.
Summary of the invention
The object of the present invention is to provide the high safety Design power supply of a kind of usage safety performance.
For reaching goal of the invention the technical solution used in the present invention be:
A kind of safety Design power supply; it is characterized in that: comprise a lithium battery group; the positive terminal of described lithium battery group and main load are connected an end and are connected with assistant load; the negative pole end of described lithium battery group is connected with the other end of main load through the first protective circuit, the negative pole end of described lithium battery group through restorability current limliting temperature control element be connected protective circuit and be connected with the other end of assistant load.
Further, described restorability current limliting temperature control element is any one in PTC components and parts, ceramic resistor, switch resistance or the thermistor.Restorability current limliting temp-controlling element is not that electronic circuit is barricaded as circuit, prevents that quiescent dissipation is on the impact of power brick storge quality.
Principle of the present invention, the lithium battery group is given main load and assistant load power supply when normally using; When emergency situations occurs; the action of the first protective circuit; cut-out is to main load supplying; and the lithium battery group still can be powered to assistant load through restorability current limliting temperature control element and the second protective circuit; assistant load still can normal running such as signal lamp, door lock, reduces the security threat to on-board crew.
Beneficial effect of the present invention: usage safety performance is high, has reduced the security threat to on-board crew.

Fig. 1 is circuit theory diagrams of the present invention.
Embodiment
Come the present invention is further specified below in conjunction with specific embodiment, but do not limit the invention to these embodiments.One skilled in the art would recognize that the present invention contained all alternatives, improvement project and the equivalents that may comprise in claims scope.
With reference to Fig. 1; a kind of safety Design power supply; comprise a lithium battery group 1; the positive terminal of described lithium battery group 1 is connected with the end that main load 2 is connected with assistant load; the negative pole end of described lithium battery group 1 is connected with the other end of main load 2 through the first protective circuit 4, the negative pole end of described lithium battery group 1 through restorability current limliting temperature control element 5 be connected the other end of protective circuit 6 with assistant load 3 and be connected.
Described restorability current limliting temperature control element 5 is any one in PTC components and parts, ceramic resistor, switch resistance or the thermistor.Restorability current limliting temp-controlling element 5 is not that electronic circuit is barricaded as circuit, prevents that quiescent dissipation is on the impact of power brick storge quality.
Principle of the present invention, lithium battery group 1 is given main load 2 and assistant load 3 power supplies when normally using; When emergency situations occurs; 4 actions of the first protective circuit; cut-out is to main load 2 power supplies; and lithium battery group 1 still can give assistant load 3 power supplies through restorability current limliting temperature control element 5 and the second protective circuit 6; assistant load 3 still can normal running such as signal lamp, door lock, reduces the security threat to on-board crew.
Claims (2)
1. safety Design power supply; it is characterized in that: comprise a lithium battery group; the positive terminal of described lithium battery group and main load are connected an end and are connected with assistant load; the negative pole end of described lithium battery group is connected with the other end of main load through the first protective circuit, the negative pole end of described lithium battery group through restorability current limliting temperature control element be connected protective circuit and be connected with the other end of assistant load.
2. a kind of safety Design power supply according to claim 1, it is characterized in that: described restorability current limliting temperature control element is any one in PTC components and parts, ceramic resistor, switch resistance or the thermistor.
