Toyota drops detail about 414-hp Hybrid-R concept powertrain

The Toyota Yaris Hybrid-R Concept has been teased already, offering up little glimpses and details of the Frankfurt-bound vehicle. And while those few, shadowy shots have been great, we've really wanted to know how this hatchback would deliver its promised 400-plus horsepower. Under hood sits a 1.6-liter, race-derived, direct-injection, turbocharged four-cylinder that powers the front wheels. Sounds peachy, but with 414 horsepower splashed across the page, we're going to need something more than a 1.6-liter, turbo four.
A supercapacitor, developed from the Toyota TS030 Hybrid Le Mans racer sits in place of a hybrid's traditional battery packs. The benefit, according to Toyota, is that power can be more rapidly absorbed and discharged than in a traditional battery system, like nickel metal-hydride.
The gas engine is joined by a trio of 60-horsepower electric motors. Two of the them power the rear wheels, while the third sits between the engine and the six-speed, sequential gearbox. Developing the same amount of power as the rear-axle motors, this centrally located motor channels power to the race-derived supercapacitor during braking, and ships extra grunt to the rear wheels under acceleration when the front wheels start to lose grip. Besides the distributive power of the central motor, the rear electric motors can adjust the amount of torque flowing to each wheel, much like a differential.

Recharge Wrap-up: BMW plans for retired batteries; automakers support dual-standard chargers

Toyota will test hybrids with silicon-carbide (SiC) power semiconductors. In Japan, Toyota has put the SiC power semiconductors into the power control units of a Camry Hybrid prototype and a fuel cell bus for a year-long test. Research suggests the SiC units will decrease electrical losses while managing power supply, thus improving overall powertrain efficiency. Current power semiconductors account for about 20 percent of electrical losses, and success with these tests could mean more efficient hybrids on the roads in the future. Read more at Hybrid Cars. Automakers from CCS and CHAdeMO camps are supporting dual-standard charging station networks. https://www.autoblog.com/bmw/, Volkswagen (CCS camp) and ChargePoint announced plans to build "express charging corridors" by installing about 100 DC fast chargers, many of which will support both types of charging. Kansas City Power & Light is partnering with Nissan (CHAdeMO camp) and ChargePoint to install DC chargers that "will charge any model of electric vehicle on the market." This leads the folks at Green Car Reports to look into whether this ends the looming standard war between automakers in the US. Read more at Green Car Reports. BMW, Bosch and utility company Vattenfall are making plans for a second life for retired BMW i3 batteries. The Second Life Batteries Alliance project will recycle the old lithium ion battery packs - which can still hold a charge - in off-grid storage and grid-stabilization applications, beginning with a grid storage system in Hamburg, Germany. Bosch has created a battery management algorithm to extend the life of the batteries and make sure they don't cause harm to Vattenfall's facilities. Read more at Transport Evolved.

NHTSA investigating 30,000 Toyota Camry Hybrids for brake assist problems

Older model Toyota Camry Hybrids are under investigation by the US National Highway Traffic Safety Administration (NHTSA) for potential braking problems. Enough complaints have poured into the NHTSA website that the agency is now taking a look at the problem, which could affect around 30,000 vehicles from the 2007 and 2008 model years. According to Reuters, 59 complaints have been submitted revolving around an "intermittent loss of assisted braking" which means the car takes longer to stop. Interestingly, the rate of complaints is increasing. Toyota is reportedly cooperating with NHTSA and there has not yet been an official recall on the Camry Hybrids. In 2006, Toyota said Brake Assist was "an electronic function that senses an emergency stop and applies increased braking power once the driver touches the brake pedal." When Toyota unveiled the 2007 Camry Hybrid, it proudly stated that the new Brake Assist function would be standard. Other Toyota hybrids have had problems with their brakes in the past, including the 2010 Prius and Lexus HS 250h hybrid. You can read some of the complaints about Brake Assist in the Camry Hybrids to the NHTSA here. People are saying that the "Check VSC" lights can come on before the brakes loose some of their power and a lot of them are being quoted repair costs of over $3,000 by Toyota dealers.
