Embodiment Construction

[0015] As shown in Figures 3 and 4, the battery temperature detection device for hybrid power includes a temperature sensor 10 containing a temperature probe 111, the shell of the temperature sensor 10 is combined with the battery case 20 in a sealed manner, and the temperature sensor 10 is located in the battery case 20 The outside of is the connection terminal 121.

[0016] Adopting the above solution, the structure is simple and reliable, and under this structure, it can work normally in the complex working environment of the automobile.

[0017] The shape of the temperature sensor 10 is bent at right angles, the probe 111 is located in the lower vertical shaft 11 of the sensor 10 , and the terminal 121 is located in the upper horizontal shaft 12 .

[0018] The above design is based on the consideration that the battery is arranged in the front cabin, and there is a possibility of washing it with water. The 90-degree bending design is adopted, and the wire harness is protec...

Abstract

The invention relates to mixed power using storage batter temperature detecting device. Temperature transducer outer covering is hermetically combined with battery container to be a whole. The temperature probe containing part of the former is set in latter. And its part out of the latter is used as terminal post. The battery temperature state information collected by the temperature transducer can satisfy whole car control demand, support with system control strategy to make the battery work under good operating state, prolong its useful.

Description

technical field [0001] The invention relates to a hybrid electric vehicle battery performance detection technology, in particular to a hybrid electric vehicle battery battery temperature detection. Background technique [0002] Hybrid technology provides the possibility of saving fuel, especially in the case of rising international oil prices has a special significance. Battery and battery parameter detection technology is one of the difficult technologies of hybrid power. One of the important parameters of the battery is the state of charge SOC, and the evaluation of the value of the SOC can be carried out through the external parameters of the battery such as current, voltage, temperature, etc. The accurate detection of temperature has an important impact on the evaluation of battery performance. Similar temperature and available SOC curves are shown in Figure 1 (10 hour rate, end voltage 1.8V); the relationship between floating charge voltage (curve B), equalizing charg...
