Unlike battery-electric cars, PHEVs don't have to be plugged in to run. If the PHEV battery is "depleted," or has discharged its all-electric range, a portion of its capacity stays in reserve to ...
A plug-in hybrid electric vehicle (PHEV) is a hybrid which has additional battery capacity and the ability to be recharged from an external electrical outlet. A plug-in electric vehicle is basically the same, without an extra internal combustion engine. In addition, modifications are made to the vehicle's control software.
Battery electric vehicles operate solely in this mode. Most plug-in hybrids operate in charge-depleting mode at startup, and switch to charge-sustaining mode after the battery has reached its minimum state of charge (SOC) threshold, exhausting the vehicle's all-electric range (AER). Although there is no technically mandated minimum all-electric ...
A battery is used only to start the car's internal combustion engine and run accessories when the engine is not running. The alternator is used to recharge the battery and run the accessories when the engine is running. The HSD system replaces the geared transmission, alternator, and starter motor with:
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe without special protective measures.
In 2005, Toyota had to fix a software glitch that caused the Prius' engine to enter "limp" mode with electric-only operation, following 68 stall complaints in the U.S. out of 160,000 worldwide sales. [ 21 ] [ 22 ] In June 2006, Toyota also recalled about 170,000 Prius models from 2004 to 2006 due to a faulty intermediate shaft and sliding yoke ...

A plug-in hybrid electric vehicle (PHEV) or simply plug-in hybrid is a type of hybrid electric vehicle equipped with a rechargeable battery pack that can be directly replenished via a charging cable plugged into an external electric power source, in addition to charging internally by its on-board internal combustion engine-powered generator.
