All the propul- sion energy comes from the primary energy source: gasoline or diesel for IC engines; hydrogen or hydrogen-based fuel for fuel cells. During operation, the energy in the PPS fluctuates in a narrow window. The PPS size is deter- mined by power rather than energy capacity. The energy-to-power ratio is in the range of 0.05–0.1 kWh/kW. That is to say, with a given power capacity, the energy storage in PPS is considered to be sufficient if it can sustain 0.05–0.1 h with the given power. Thus, the PPS is more an energy buffer than energy storage. This is also the origin of the name PPS (peaking power source). At present and in the immediate future, ultracapacitors and high-power batter- ies or their combination are the most promising candidates as the PPS of the PPS charge sustained HEVs (for details, refer to Chapter 12 of Peaking Power Source and Energy Storage).With the development and maturing of advanced battery technologies, the energy storage capacity of batteries has significantly improved. Obviously, using high-energy batteries only as a PPS is a waste.The plug-in hybrid electric drive train is designed to fully or partially use the energy of the energy storage to displace part of the primary energy source, such as gasoline, diesel, hydrogen, and so on.All the configurations discussed in Chapter 5 can be employed in plug-in hybrid electric drive trains. Most of the differences from the PPS sustained hybrid drive train are in the drive train control strategy, energy storage design, and perhaps, slightly different electric motor power design. This chapter will concentrate on these three topics.10.1 Statistics of Daily Driving DistanceCharging the energy in the energy storage device from the utility grid, to displace part of the petroleum fuel, is the major feature of the plug-in hybrid electric vehicles (PHEVs). The amount of petroleum fuel displaced by the utility electricity depends mainly on the amount of electrical energy per recharge, that is, the energy capacity of the energy storage; total driving dis- tance between recharges, that is, usual daily driving distance; and electrical power usage profiles, that is, the driving cycle features and control strate- gies. To achieve optimal design, especially for the energy storage system, understanding the daily driving distance in a typical environment is very helpful.Figure 10.1 is a histogram showing the daily driving distance distribu- tion and the cumulative frequency derived from the 1995 National Personal Transportation Survey data.1,2 The cumulative frequency or utility factor in reference1 represents the percentages of the total driving time (days) during which the daily driving distances are less than or equal to the said distance on the horizontal axis. Figure 10.1 reveals the fact that about half of the daily driving distance is less than 64 km (40 miles). If a vehicle is designed to have 64 km (40 miles) of pure EV range, that vehicle will have half of its total driving distance from the pure EV mode. Even if the daily traveling distance is beyond this 60 km (40 miles) pure EV range, a large amount of the petroleum fuel can be displaced by electricity, due to the pure EV mode taking a large portion of the daily travel. Research also shows that even if the pure EV range is less than 64 km (40 miles), such as 32 km (20 miles), there is still a large amount of petroleum that can be displaced in normal daily driving.FIGURE 10.1 Daily driving distance distribution and cumulative factor10.2 Energy Management StrategyFirst, some definitions about PHEV are introduced:Charge-Depleting (CD) Mode: An operating mode in which the SOC of the energy storage may fluctuate, but on average decreases while driving.Charge-Sustaining (CS) Mode: An operating mode in which the SOC of the energy storage may fluctuate but on average is maintained at a certain level while driving.All Electric Range (AER): After a full recharge, the total miles (kilo- meters) driven electrically (engine off) before the engine turns on for the first time.Electric Vehicle Miles (EVM) or Kilometers (EVKM): After a full recharge, the cumulative miles or kilometers driven electrically (engine off) before the vehicle reaches CS mode.Charge-Depleting Range (CDR): After a full recharge, the total miles or kilometers driven before the vehicle reaches CS mode. It should be noted that EVM or EVKM dictates pure electric driving. However, CDR may include engine propulsion, but the on-average SOC of the energy storage decreases till the sustaining level.PHExx: A PHEV with useable energy storage equivalent to xx miles of driving energy on a reference driving cycle, where xx stands for the mileage number. For example, PHEV20 can displace petroleum energy equivalent to 20 miles of driving on the reference driving cycle with off-board electricity. A similar definition can be made in kilometers. It should be noted that PHEV20, for example, does not imply that the vehicle will achieve 20 miles of AER, EVM, or CDR on the reference cycle, nor any other cycle. Operating characteristics also depend on the power ratings of components, the power train control strategy, and the nature of the driving cycle.10.2.1 AER-Focused Control StrategyThe idea of this control strategy is to use the energy of the energy storage intensively in the AER.3,4 One possibility is to allow the driver to manually select between a CS mode and a full EV operating mode. This design could be useful for vehicles that may be used in the region where combustion engine use is restricted. This design provides flexibility for the driver to determine the times that the pure EV mode is used. For example, in a trip that includes places where pure EV operation is required, the driver can select the pure EV operating mode just prior to entering this area in order to have sufficient range. In other places, the vehicle may be operated in pure EV mode or CS mode, depending on the energy status of the energy storage and the power demand. In normal conditions, where the trip does not include mandatory pure EV operation, the driver could select the pure EV mode at the start of the trip in order to fully use the energy of the energy storage to displace the petroleum fuel, until the energy of the energy storage reaches its specified level at which the CS mode will start automatically.This energy management approach clearly divides the whole trip into pure EV and CS modes. Thus, the design and control techniques developed for EV and HEV in the previous chapters can be used. When series hybrid config- uration is used, the power rating designs of the motor, engine, and energy storage are almost the same as in the CS hybrid. The motor power guarantees the acceleration and gradeability performance, the engine/generator power supports the vehicle driving at a constant speed on flat or mild grades, and the energy storage power is larger (or at least not smaller) than the motor power minus the engine/generator power. However, the energy storage has to be designed so that its useable energy can meet the requirement of the pure EV range. When parallel or series/parallel configuration is used, the motor power should be designed to meet the peaking power requirements of the reference driving cycles. Otherwise, the vehicle cannot follow the speed pro- file of the drive cycle, and will be somewhat sluggish, compared to the driver expectation.The traction power computations in typical driving cycles have been dis- cussed in detail in previous chapters. However, for the reader’s convenience, it is repeated below.The traction power on the driven wheels includes the rolling resistance, aerodynamic drag, inertial force of acceleration, and grade resistance, which can be expressed as where M is the vehicle mass in kg, V is the vehicle speed in m/s, g is the gravity acceleration, 9.81 m/s2, ρa(bǔ) is the air mass density, 1.205 kg/m3, CD is the aerodynamic drag coefficient of the vehicle, Af is the front area of the vehicle in m2, δ is the rotational inertia factor, dV/dt is the acceleration in m/s2, and i is the road grade. In standard driving cycles, flat roads are used. Figure 10.2 is a diagram showing the vehicle speed and the traction power, on the driven wheels, versus the traveling distance in the FTP75 urban driving cycle. The vehicle parameters used in this computation are listed in Table 10.1. Figure 10.2 indicates that the peaking traction power on the driven wheels is about 25 kW. However, there are power losses in the path from the energy storage to the driven wheels. In order to meet the power requirement, the motor output power should be designed to account for the power losses from the motor shaft to the driven wheels. Suppose that the efficiency from the motor shaft to the driven wheels is 90%; then the motor shaft power rating is about 28 kW. It should be noted that this required motor power is also related to the vehicle speed at which this peak power occurs. For example, the peaking power in Figure 10.2 occurs at a vehicle speed of 50 km/h (31.25 mph). In the motor power design, we must be sure that the motor can produce this peak power at this vehicle speed. Similarly, the peaking power of the energy storage should include the losses in the electric motor, the power electronics, and the transmission. Suppose that the efficiencies of the motor and power electronics are 0.85 and 0.95, respectively; then the power capacity of the energy storage is about 34.7 kW in this example. Table 10.2 lists the motor power and the energy storage power in FTP75 urban, FTP75 highway, LA92, and US06 driving cycles.FIGURE 10.2 Vehicle speed and traction power in an FTP75 urban driving cycle.Integrating Equation 10.1, over the driving time in a driving cycle, can give the energy consumption by the driven wheels as shown in Figure 10.3. Here, no regenerative braking is included. When including energy losses in the power electronics, the motor, and the transmission, the useable energy in the energy storage, for 32 km (20 miles) and 64 km (40 miles) of pure EV driving in typical driving cycles, is listed in Table 10.3.In vehicle design, an appropriate reference driving cycle should be selected. An aggressive driving cycle, such as US06, will need a large motor drive and energy storage, but will also give good vehicle acceleration and grade- ability performance. On the contrary, a mild driving cycle, such as FTP75, will lead to a small motor drive and energy storage, but also a sluggish vehicle performance.The following figures show simulation results of the drive train in the ref- erence driving cycle, FTP75 urban. The vehicle parameters listed in Table 10.1 were used. The total energy in the energy storage, fully charged, is 10 kWh. The simulation ran nine sequential cycles and the pure EV mode was started at the beginning of the simulation, until the SOC reached about 30%, beyond which the CS mode was started. The control strategy in the CS mode employed the constrained engine on–off control strategy, discussed in Section 8.2.3. In the simulation, 400 W of constant auxiliary power was added at the terminal of the energy storage.Figures 10.4 and 10.5 show the engine power and the motor power. Figure 10.6 shows the SOC of the energy storage, and the remaining energy in the energy storage, versus the traveling distance. The pure EV mode range is about 32 km (20 miles). Figure 10.7 shows the engine operating points overlapping its brake-specific fuel consumption map.Figures 10.8 and 10.9 show the fuel and electric energy consumption scenarios, in metric and English units, respectively. It can be seen that when the traveling distance is less than four driving cycles (42.5 km or 26.6 miles), the vehicle can completely displace the petroleum fuel with electricity with pure EV mode. The total electric energy consumed is about 7.1 and 15.5 kWh per 100 km, or 4.05 miles/kWh (Figure 10.9). With the increasing total traveling distance, the percentage of the fuel displacement decreases, since the CS modes take larger percentages of the trip. For nine sequential driving cycles (96 km or 60 miles), the fuel and electrical energy consumptions are about 3.2 L/100 km (Figure 10.8) or 74 mpg (Figure 10.9), and 7.42 kWh/100 km (Figure 10.8) or 8.43 mile/kWh (Figure 10.9).FIGURE 10.3 Energy consumption by the driven wheels versus driving distance in typical driving cycles.FIGURE 10.4 Engine power versus traveling distance in FTP75 urban driving cycle with AER mode.FIGURE 10.5 Engine power versus traveling distance in FTP75 urban driving cycle with AER mode.FIGURE 10.6 SOC and the remaining energy in the energy storage versus traveling distance in FTP75 urban driving cycle with AER mode.FIGURE 10.7 Engine operating points overlapping its fuel consumption map in FTP75 urban driving cycle with AER mode.FIGURE 10.8 Fuel and electric energy consumption versus the number of FTP75 urban driving cycle and traveling distance with AER mode in metric unit.Simulation of the same design in the LA92 driving cycle has also been performed. The results are illustrated in the following figures (Figures 10.10 through 10.15). Comparing the two driving cycles, the LA92 driving cycle has higher vehicle speed and larger acceleration rate. The pure EV range is shorter, and the fuel and electric energy consumptions are higher than in FTP75 urban driving cycles.設(shè)計(jì)和插電式混合動(dòng)力電動(dòng)汽車控制原則正如在前面的章節(jié)，PPS
