The invention provides a method and a device for obtaining the internal temperature of a cylindrical battery. The method for obtaining the internal temperature of the cylindrical battery comprises thefollowing steps: obtaining a current current amplitude of the battery, a battery surface temperature corresponding to the current current amplitude, and the air temperature in a volume in an environment where the battery is located; obtaining the current resistance ratio Rin / Rout corresponding to the current current amplitude; obtaining the battery internal temperature corresponding to the current current amplitude according to the current resistance ratio Rin / Rout corresponding to the current current amplitude, the battery surface temperature corresponding to the current current amplitude and the air temperature of the volume in the environment where the battery is located. The invention enables a battery management system controller and a driver to obtain the accurate battery internal temperature, so that appropriate measures can be taken to avoid the risks of the lowering of the battery using efficiency, the reduction of the service life of the battery and the exploding of the battery due to the high temperature.

On-line integrated monitoring device and method for deep well oil and gas reservoir temperature and pressure
ActiveCN103953330BGuaranteed survivabilitySecurity SensitivitySurveyConstructionsGratingModem device
The invention provides a deep well hydrocarbon reservoir temperature and pressure intelligent on-line monitoring device. A test plane and a transition plane are processed in the eccentric oil pipe, an optical fiber Bragg grating strain sensor is formed on the test plane through high-temperature bonding, one end of the optical fiber Bragg grating strain sensor is fixedly arranged on the test plane, and the other end of the optical fiber Bragg grating strain sensor passes through an optical fiber channel arranged between the test plane and the transition plane to reach the transition plane. One end, near the transition plane, of the optical fiber channel is connected with a stainless steel capillary pipe, the optical fiber penetrates into the stainless steel capillary pipe after being led out from the optical fiber channel, the stainless steel capillary pipe approaches to the transition plane and extends to a position near an optical fiber modem interface on the well, and the optical fiber is protected from being influenced by external severe environment in the whole process. The on-line monitoring device related by the invention realizes the deep well oil pipe structure integration, and has the advantages that the size is small, no additional auxiliary structure is adopted, the anti-interference capability is high, signals are stable and reliable, the response speed is high, and the like, and the on-line obtaining precision and the reliability of key information such as deep well hydrocarbon reservoir temperature and pressure can be obviously improved.
