From the Table 2 the following conclusions can be drawn:
- The maximum power required to move the vehicle on this drive cycle is about 85kW, hence, the prime mover (combination of ICE and EM in case of HEVs and EM in case of EVs) should be able to deliver the required power.
- The maximum braking power is about 89kW and a fraction this power can be recovered by using regenerative braking.
- The maximum and minimum acceleration that the vehicle experiences are 2.7m/s2 and 2.64m/s2. EMs are better suited for such rapid acceleration because the torque produced by the EMs have higher overloading factor compared to ICEs, hence, a smaller EM will be sufficient.
Moreover, from Figure 2 and 3 it can be seen that the vehicle is subjected to frequent start-stop. Since the ICEs tend to be very fuel inefficient for such frequent start-stop operation, it is wise to use only EM as the prime mover.
Japanese JP- 10-15
The Japanese JP- 10-15 test cycle is currently used in Japan for emission certification and fuel economy for light duty vehicles. It is derived from the 10 mode cycle by adding another 15-mode segment of a maximum speed of 70 km/h. The distance of the cycle is 4.16 km, average speed 22.7 km/h, duration 660 s (or 6.34 km, 25.6 km/h, 892 s, respectively, including the initial 15 mode segment). The Japanese JP- 10-15 test cycle is as shown in Figure 4 and in Figure 5 the acceleration versus time curve is given.
The driving cycle parameters for Japanese JP- 10-15 test cycle are as shown in Table 3.
