With an electric water pump, the Prius engine is the first production engine that requires no accessory belts, which also further improves fuel economy. [13] The electric motors and other components of the hybrid powertrain are also smaller and more efficient. [14] Toyota estimates the new inverter, motor and transaxle are 20 percent lighter.
Like the second generation Prius, the third generation Prius battery pack is made up of the same type of 1.2 volt cells. It has 28 modules of 6 cells for a total nominal voltage of only 201.6 volts. A boost converter is used to produce 500 volt DC supply voltage for the inverters for MG1 and MG2. [ 11 ]
A battery management system (BMS) is any electronic system that manages a rechargeable battery (cell or battery pack) by facilitating the safe usage and a long life of the battery in practical scenarios while monitoring and estimating its various states (such as state of health and state of charge), [1] calculating secondary data, reporting that data, controlling its environment ...
This is effectively accomplished in the Generation 3 Prius HSDs (Prius v, Prius Plug-in and Prius c), although the Generation 3 HSD has this second planetary gear set fixed at 2.5:1, rather than switching between 1:1 and 2.5:1 as the "carrier" is held fixed. Power-splitter series-hybrid Toyota Prius
2006 Prius cut-away in a Toyota showroom in Paris. The Prius uses an all-electric A/C compressor for cooling, an industry first, [7] and also adds an electric power steering system to further minimize engine belt-driven engine accessories. Combined with a smaller and lighter NiMH battery, the XW20 is more powerful and more efficient than the XW10.
The Cooper sisters are donor-conceived, which is what, in part, prompted Lyndsay Cooper to do a home DNA test. They learned that the sperm donor carried the mutation, which was passed onto them.
The CDC said the patient's sample showed mutations in the hemagglutinin (HA) gene, the part of the virus that plays a key role in it attaching to host cells. The mutations seen in the patient are ...
The Second Generation Prius contains a 1.310 kWh battery, composed of 28 modules. Each battery module is made of six individual 1.2 V 6.5 Ah Prismatic NiMH cells in series forming a 7.2 V 6.5 Ah module with 46 Wh/kg energy density and 1.3 kW/kg output power density. [193] Each module contains an integrated charge controller and relay.
