插入式普锐斯的电池设计非常有趣,它分成三个包。主电池包,A包,B包。当A包耗尽电池的时候,A包会自动断开。B包会接入,当它耗尽电量的时候,也会自动断开。主电池包是唯一接受电能回收的单元。
注意这是两个包,还有一个包在下面的位置:
更加详细的图报名了风扇的位置:
电池组内部结构在专利上没有特别好的参考,toyota的专利很多,有一些是相互掺和在一起使用的,特别是目前这种最新的结构,以下是我的揣测:
附录:
"The 2010 Prius PHV has three lithium-ion battery packs, one main and two additional packs (pack one and pack two) with a combined weight of 330 pounds. Each battery pack contains 96 individual 3.6 V cells wired in series with a nominal voltage of 345.6 V DC.
When the PHV is fully charged the two additional battery packs supply power to the electric motor. Pack one and pack two operate in tandem with main battery pack but only one at a time on the individual circuit. When pack one’s battery’s charge is depleted, it will disconnect from the circuit and pack two will engage and supply electrical energy to the drive line. When pack two has depleted it will disconnect from the circuit and the vehicle will operate like a regular hybrid. Pack one and pack two will not reengage in tandem with the main battery pack until the vehicle is plugged in and charged.
The Prius PHV’s larger HV battery assembly requires additional cooling. The vehicle is equipped with three battery-cooling blowers, one for each of the three battery packs. Each battery pack also has an exclusive intake air duct. One cooling blower cools the DC/DC converter.
Like all Toyota hybrids, the lithium-ion batteries are built to last for the life of the vehicle. This first-generation lithium battery has undergone more than three years of coordinated field testing in Japan, North America and Europe in a wide variety of climatic environments and driving conditions."
