Awide-line metal film is proposed to heat the battery so as to meet the low-temperature operating requirements of the 8×8 wheeled electric vehicle. Experimental results prove that the wide-line metal film heating method can significantly improve the low-temperature performance of the battery. A diagram of the test platform is shown in Fig. 1.
To meet the high reliability requirement of the 8×8 wheeled electric vehicle, a wide-line metal film heating method is proposed, in which two pieces of wide-line metal film are placed on the two largest surfaces of the battery cell. The wide-line metal film is printed on a FR4 board or aluminum PCB, and its thickness is 1 mm.
Octadecane (C 18 H 37) and pentadecane (C 15 H 31) are both appropriate heat transfer media for battery cooling and heating using PCS cycles. The simulation results indicated that the direct blowing method placed a greater additional heat load on the air conditioning system if the cabin ventilation effect was not taken into account.
In order to heat up the simulated battery from −15 ± 5°C and −20 ±5°C–0°C, less than 300 s and 500 s respectively was required under 40°C heating condition, and 1200 s and 1500 s respectively under 20°C heating condition.
