Abstract

The utility model discloses a key component detection system for new energy vehicle motor and capacitors. The key component detection system comprises a central processor unit connected with a first A/D collecting module, a second A/D collecting module, a CAN communication module and a display driving module. The first A/D collecting module is connected with multiple first temperature sensors arranged on bolts of the new energy vehicle capacitors, and the second A/D collecting module is connected with multiple second temperature sensors arranged on stator windings and bearings of the new energy vehicle motor. The CAN communication module is connected with a whole vehicle CAN module of a new energy vehicle. The display driving module is connected with a first display screen. From the problem caused by bolt loosening, the characteristic that because high currents flow through the loosened bolts, the bolts are high in temperature is used, the temperature sensors are installed on the bolts, so that bolt temperatures are obtained and monitored in real time, and whether the bolts loosen or not is indirectly checked.

Description

New forms of energy vehicle motor and cond critical component checking system

Technical field

The utility model relates to new forms of energy car field, especially a kind of new forms of energy vehicle motor and cond critical component checking system.

Background technology

Super capacitor on hybrid-power bus discharges and recharges with the form of series connection group, and each ultracapacitor all has positive and negative terminals, and super capacitor is usually operated at the state of high voltage and high current.Super capacitor is due to the material of capacitor case both hard and crisp feature, staff is connecting wire, when binding bolt, need to use appropriate torsional moment, torsion is inadequate, and super capacitor is arranged on the car of walking, more easily, because car walking is jolted, wire traction, easily causes bolt to occur loosening problem after long-term actual use of being everlasting.When bolt occurs loosening, again with high voltage and high current state work, easily there is arcing phenomenon in super capacitor, large electric current arcing may damage cond to be affected bus and normally move near bolt, more may cause bus combustion explosion, threaten the serious consequence of passenger's person life security.

Utility model content

The purpose of this utility model is to provide a kind of new forms of energy vehicle motor and cond critical component checking system, reminds chaufeur to carry out the further loosening work of prevention bolt, stops the serious consequence causing because of little hidden danger.

The technical solution of the utility model is: a kind of new forms of energy vehicle motor and cond critical component checking system, comprise a central processor unit, it is characterized in that: described central processor unit connects one the one A/D acquisition module, one the 2nd A/D acquisition module, one CAN communication module and a driver module, a described A/D acquisition module connects a plurality of the first temperature sensors, described a plurality of the first temperature sensor is arranged on the bolt of new forms of energy car super capacitor, described the 2nd A/D acquisition module connects a plurality of the second temperature sensors, described a plurality of the second temperature sensor is arranged on the motor stator winding of new forms of energy car, on bearing, described CAN communication module connects the car load CAN module of new forms of energy car, described driver module connects a read-out.

In the utility model one embodiment, also comprise a power module, with thinking described checking system power supply.

In the utility model one embodiment, also comprise an externally fed module, described externally fed module connects described power module.

The problem that the utility model causes from bolt looseness, utilizes bolt that high-current flow becomes flexible excessively to cause the feature of bolt high temperature, mounting temperature sensor on bolt, and Real-time Obtaining and monitoring bolt temperature, whether indirect review bolt is loosening.

Brief description of the drawings

Fig. 1 is system principle frame diagram of the present utility model.

Detailed description of the invention

For above-mentioned feature and advantage of the present utility model can be become apparent, special embodiment below, and coordinate accompanying drawing, be described in detail below, but the utility model is not limited to this.

As shown in Figure 1, the utility model provides a kind of new forms of energy vehicle motor and cond critical component checking system, comprise a central processor unit, described central processor unit connects one the one A/D acquisition module, one the 2nd A/D acquisition module, one CAN communication module and a driver module, a described A/D acquisition module connects a plurality of the first temperature sensors, described a plurality of the first temperature sensor is arranged on the bolt of new forms of energy car super capacitor, described the 2nd A/D acquisition module connects a plurality of the second temperature sensors, described a plurality of the second temperature sensor is arranged on the motor stator winding of new forms of energy car, on bearing, described CAN communication module connects the car load CAN module of new forms of energy car, described driver module connects a read-out.

In order to allow the better work of system, also comprise a power module, with thinking described checking system power supply, in order to allow the more reliable and more stable work of whole system, also comprise an externally fed module, described externally fed module connects described power module, with thinking described power module charging.

In conjunction with Fig. 1, the problem that the utility model causes from bolt looseness, utilizes bolt that high-current flow becomes flexible excessively to cause the feature of bolt high temperature, mounting temperature sensor on bolt, Real-time Obtaining bolt temperature.System is responsible for real-time bolt looseness Check processing, and drives read-out report to show excess temperature place according to testing result by driver module, and loosening point reminds chaufeur to carry out the further loosening work of prevention bolt, stops the serious consequence causing because of little hidden danger.In addition, for preventing drive motor and the work of electrical generator excess temperature, extend the service life of motor critical component, guarantee motor is normally worked, and is arranged on motor stator winding and bearing place mounting temperature sensor, accurately the temperature information of detected electrons winding and bearing.

The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
