Description
- The present application is a divisional of U.S. patent application Ser. No. 13/474,415, filed on May 17, 2012, by Rippel et al., entitled INTEGRATED MOTOR DRIVE AND BATTERY CHARGING SYSTEM, which is a continuation of PCT Application number PCT/US2010/057057, by Rippel et al., entitled INTEGRATED MOTOR DRIVE AND BATTERY CHARGING SYSTEM, filed Nov. 17, 2010, both herein incorporated by reference in their entireties, which claims priority of U.S. Provisional Application No. 61/262,117, by Rippel et al., filed Nov. 17, 2009, herein incorporated by reference in its entirety.
- Electric motors and charging systems for vehicles need to be light weight, compact, and convenient. Induction motors are often used in vehicles. A separate inverter charging system is used to charge the battery from a utility power line, such as a 220 VAC wall socket.
-
FIG. 1 shows a simplified schematic of a prior art induction motor andbattery charging system 100. Thestator 120 has threewindings inverter 150 is connected between thebattery 105 and thewindings inverter 150 typically is controlled by a controller (not shown inFIG. 1 ) to convert the DC power from thebattery 105 to AC power for thewindings rotor 140. - In this
system 100, thebattery 105 is charged by a separate AC toDC charger 110, which is connected toutility power 115. Thecharger 110 is connected across thebattery 105. - With such a system, the
charger 110 adds additional weight to the vehicle if integrated or separately carried on board the vehicle. If separate from the vehicle, thecharger 110 might not be present, in the event it is needed for convenience or opportunity charging, or in case of an emergency. - What is needed is a charging system for electric vehicles that is light weight and convenient.
- In one possible embodiment, a motor charging system for connection with a battery is provided having a rotor and a stator. The stator has Y-connected windings connected together connected at a neutral node. An inverter is connected between a battery bus and the stator windings.

FIG. 2 shows a simplified schematic of an induction motor andbattery charging system 200 for a single phase Y-connected stator winding 220. In this embodiment, thebattery 205 is charged by singlephase utility power 215 through the winding 220. Adouble pole switch 210 is placed in the Y-connected winding 220 circuit to disconnect thewindings utility power 215 via anoptional EMI filter 212. In the open Y configuration, thewindings inverter 250 is controlled bycontroller 270 to convert theAC utility power 215 passed through thewindings - In
FIG. 2 , theinverter 250 is comprised of diode connected Insulate Gate Bipolar Transistors or IGBTs which are controlled bygate drivers 275 in thecontroller 270. Other inverter circuits are possible.Current sensors windings 220 to sense the currents ia, and ib in thewindings windings Current sensor 202 senses the battery bus current ibus. Thecontroller 270 also has sensor inputs to sense the voltage Vbat across thebattery 205 and the voltage Vab of theutility power 215. - In various embodiments, the
controller 270 monitors the utility voltage and controls current in thewindings 220 so as to track the AC voltage so as to end up with unity power factor. Another function of thecontroller 270 is to monitor current to thebattery 205 andbattery 205 voltage to regulate the current going intobattery 205 and/or at some point switch to regulate voltage intobattery 205 and reduce current intobattery 205. - During charging, the
rotor 240 may be locked or otherwise secured. During motor operation, theswitch 210 is switched so that thewindings utility power 215 from the winding 220. Theutility power 215, and optionally in some embodiments theEMI filter 212, may be physically disconnected from thecircuit 200. -
FIG. 3 shows a simplified schematic of an induction motor andbattery charging system 400 for a three phase delta H-bridge configured winding 450. In this embodiment, thebattery 405 is charged by threephase utility power 415 through the winding 420. - In the motoring mode, the
switches switches 450 y are held off. - It is understood that in various embodiments, the
utility power 415, and in some embodiments (not shown) therecharge filter 412, may be plugged/unplugged from thecircuit 400 for charging/motoring. Thus, it is likely wise to placerecharge switches 410 in series with therecharge port 414. This provides added safety. Theoptional recharge switches 410 may be utilized to connect theutility power 415 via theoptional recharge filter 412 during recharge (or when generating DC power at the port 414). - An advantage of some embodiments of the open delta H-bridge configuration is the phase ripple fundamental frequency is 2f and peak amplitude at ripple/peak modulation voltage is equal to 1. This compares with 1.15 for conventional. Thus, high frequency AC losses in some winding embodiments are reduced by 30%. Fundamental ripple on
bus capacitor 407 is increased from 2f to 4f and ripple magnitude is reduced by a factor of 2*sqrt3. - In some embodiments, the
switches 450 x may be replaced each with sub phases and interphase transformers to provide further ripple attenuation. This may be desired in some embodiments, so that therecharge filter 412 can be down sized. -
FIG. 4 shows a simplified schematic of an induction motor andbattery charging system 500 for a three phase delta H-bridge configured winding 520 with interphase transformers or averaging transformers. With this embodiment, the switches 550 y are operated in six-step for motoring (tri-state off for recharge mode). Theswitches 550 x are operated in pulse width modulation for both motoring and recharge. For each subphase, duty cycles are the same length, but shifted +/−T/3 relative to the nearest neighbor subphase. In motoring mode, the harmonic currents on themotor windings 520 are reduced 9 times and the frequency is increased 3 times as compared to the circuit 400 (FIG. 3 ). The ripple currents and losses in the DC voltage bus are very low due to harmonic cancelation. Motor losses are minimized because voltages and currents are near sinusoidal. Further, the CV2f losses are reduced to nil, due to reduced common-mode components. - In recharge mode, harmonic cancelation by the
interphase transformers 525 a-c is such that the lowest harmonics are at 6f with a voltage reduction of 3 times as compared to thecircuit 400 ofFIG. 3 . Also, capacitance filters 513 is reduced 27 times for a given voltage ripple as compared to thecircuit 400 ofFIG. 3 . - Furthermore, phase-to-
phase capacitors 513 on the order of 10 microFarads and 100 microFarads across the utility power lines may be added to provided improved harmonic cancelation. Thus, various embodiments have a great advantage in that they have relatively low ripple and a relatively small filter capacitance. This is especially true where the motor is large and the stator inductance Ls is small. - Typically, in the various embodiments, a
port 514 is provided for connection to utility power (not shown inFIG. 5 ). Further in some embodiments, theport 514 could be used to provide AC power to an external device (not shown). - Although in the circuit shown in
FIG. 4 , 550 y is switched in six step while 550 x is PWM controlled sinusoidally to produce sinusoidal phase currents, other embodiments are possible. For example, in other embodiments 550 y may “mirror” 550 x in operation, switched at the fundamental frequency of the voltage imposed on each winding rather than at the switching frequency. - With various embodiments in accordance with the open delta h-bridge configuration, the recharge power rating may be reduced by 1/sqrt3 relative to a three phase Y-connected circuit. On the other hand, a benefit is that at the reduced power, where most of the recharge energy will flow, the magnetic losses are greatly reduced. With ΔB reduced by 1/(2*sqrt3) and f increased 2 times, the magnetic losses will be reduced by more than 3 times.
- In various embodiments, charging through the windings may present problems which can include capacitance between winding and case of motor. Common mode currents can be generated in that coupling. One solution is to isolate the motor from the vehicle to prevent currents on the frame of the vehicle, which could cause shock hazard. This may also include a non-conducting mounting and a non-conducting motor shaft, or coupling thereto. In one possible embodiment to reduce capacitive charge build up is to utilize a non-conductive motor casing.
- In some embodiments, during charging, it is preferable to lock the rotor to keep the vehicle from inadvertently moving. As there is not always a clutch in electric vehicles, a rotor locking mechanism (not shown) may be used to lock the rotor. In other embodiments, the rotor could be withdrawn from the stator, or in other embodiments, open connections of squirrel cage, for example opening circuiting the shorting rings. In yet another embodiment, a shield may be inserted to block the coupling from the windings to the rotor, for example a conductor sleeve inserted between the rotor and stator when charging.
- With charging through the winding of a single phase motor there is not generally a net torque on rotor, but rather it will oscillate back and forth. This is not true for three phase motors, as charging current through winding will create a unidirectional torque on the rotor.

FIG. 5 shows a simplified schematic of an induction motor andbattery charging system 600 for a three phase delta H-bridge configured winding 650. In various embodiments, in addition to the AC power atports 614 a-c, DC power may also be provided atport 614 atDC port 614 d. The DC power may be used to boost the recharge power. Although not shown inFIG. 5 , interphase transformers 525 (FIG. 4 ) may be included in this embodiment. - Although not every feature is shown in every embodiment, features from various embodiments may be utilized in other embodiments, for example controllers, capacitor filters, drivers, sensors, etc. Additionally, not every feature shown is necessary in every embodiment, whether explicitly identified as optional or not.
- It is worthy to note that any reference to “one embodiment” or “an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in an embodiment, if desired.
