The present application provides a temperature control component, which includes a first side plate, a second side plate and a first buffer plate. A cavity is formed by the second side plate and the first side plate; the first buffer plate is disposed between the second side plate and the first side plate to divide the cavity into multiple channels, and at least part of the first buffer plate extends obliquely from the first side plate towards the second side plate. The present application also provides a battery pack, which includes the temperature control component described above. When external air flows through the channels of the temperature control component, heat dissipation treatment for batteries could be realized. During use of the battery pack, expansion forces of two adjacent batteries extrude the first side plate and the second side plate respectively. Because at least part of the first buffer plate extends obliquely, the expansion forces transmitted to the first buffer plate are reduced, thereby extending the service life of the temperature control component. Moreover, the at least part of the first buffer plate which extends obliquely is more prone to a bending deformation under the action of the expansion forces, so that the temperature control component could absorb the expansion forces of the batteries in time, thereby improving the service life of the batteries.

For effective monitoring of battery health, it is important that the temperature characteristics of the battery are monitored. However, in certain battery pack designs, the number of batteries in the stack can be high, so sensors for measurement will not be able to monitor all the batteries in the stack. Existing battery monitoring approaches fail to tackle this problem. The disclosure herein generally relates to battery monitoring, and, more particularly, to method and system of predicting temperature distribution in a battery pack. In this approach, the system calculates a lumped conductance value for a battery pack being monitored, and in turn uses the value of the lumped conductance to predict a temperature distribution value in the battery, which is indicative of health of the battery pack.

The disclosure relates generally to methods and systems for determining heat transfer rates between battery pack and coolant channel with varying coolant flow rate in a real-time. A lumped conductance generated between the battery pack and a coolant channel is used to determine the heat transfer rates between the battery pack and the coolant channel. Conventional techniques for calculating the lumped conductance between the battery and the coolant channel either use experimental methods or rely on the heat transfer correlations in simple geometry. The present disclosure calculates the lumped conductance by understanding an internal structure of a cylindrical battery pack using a high-fidelity computational fluid dynamic (CFD) simulation. This will help in determining the heat transfer rates of the battery pack in the real-time at the battery core especially when the coolant channel side hydrodynamic conditions change with time due to the variable coolant flow rates.
