A Piping & Instrumentation Diagram (P&ID) is a schematic layout of a plant that displays the units to be used, the pipes connecting these units, and the sensors and control valves. Standard structures located on a P&ID include storage tanks, surge tanks, pumps, heat exchangers, reactors, and distillation columns.
In the battery thermal management of electric vehicles, the maximum temperature (MTBM) and maximum temperature difference (MTDBM) of a battery module are the most …
It is based on the principle of latent heat storage, which maintains the temperature constant with the high energy storage density [22]. For electronic devices with pulsed heat flux density, the PCM-based heat sink can effectively absorb the heat during pulse operation and return to the device for devices during low-temperature operation, so …

Highlights. A simplified yet effective optimizing route for cooling structure is proposed. The influence order is "contact angle" > "inlet velocity" > "channel number". Channel number shows slight influence in large battery module. The contact angle with the most significant influence should be fixed at 70°.
Compared with other cooling methods, liquid cooling has been used commercially in BTMSs for electric vehicles for its high thermal conductivity, excellent …
However, it''s worth noting that the structure of an indirect liquid cooling system can be complex, and the addition of cooling pipes or cooling plates will also bring additional weight. In addition, the system requires high contact between the battery and the cooling pipes/plates, and incomplete contact will seriously affect the cooling efficiency [ …

This paper used the computational fluid dynamics simulation as the main research tool and proposed a parameter to evaluate the performance of the cold plate in …
Liquid-cooling is also much easier to control than air, which requires a balancing act that is complex to get just right. The advantages of liquid cooling ultimately result in 40 percent less power consumption and a 10 percent longer battery service life. The reduced size of the liquid-cooled storage container has many beneficial ripple effects.
Heat exchanger calculations are based on the log mean temperature difference. = ∆ ∆ 2 − ∆ 1 ∆ = =. ∆ 2 Τ∆ 1. =. 1Τ h + 1 Τ h. h, −, − h, −, h, −, ൗ h, −, hi and ho can be calculated using the Nusselt number correlations shown earlier. Another way to size a heat exchanger would be to use the effectiveness-NTU method.
They found that the temperature increase in the battery of the direct-contact liquid-cooling system was 70–80 % lower than that of the indirect-contact liquid-cooling system. Wang et al. [ 21 ] employed No. 10 transformer oil as the immersion coolant for 10 Ah LIBs cells.
