How to fix a $4,000 hybrid battery problem with vinegar and baking soda

This is one of those 'Don't try this at home if you don't know what you're doing' DIY tales. Two weeks after imgur user "scoodidabop" bought a used Toyota Camry Hybrid with no warranty, he got the Christmas Tree dash display with warnings like "Check VSC System," "Check Hybrid System," and the Check Engine light. After some Internet sleuthing he figured it could be a faulty brake actuator, assuming the hybrid system warning was a false alarm. But it wasn't the actuator, it was the battery, a Toyota dealer telling him that his battery had "gone bad," and he'd need $4,457 to replace it. Then he had a brainstorm: it could be one of the cells that's gone bad, not the whole battery. Scoodidabop has some experience as an electrician, so he figured he could test it and replace any bad cells for about $45 apiece. He removed the battery unit from the trunk and over the course of two hours tested all 68 cells four times. He found nothing wrong. So he devised another type of test and checked every cell again. He couldn't find a problem with any of them. Turns out the problem wasn't in the cells, but with the dirty and corroded copper connectors at the ends of the high-voltage cables. He pulled the 34 connectors and their steel nuts, soaked them in vinegar, gave them a light steel wool scrub, soaked them in baking soda and water to counteract the vinegar, applied an anticorrosive and reinstalled them. That took an hour. When he replaced the battery, the warning lights had all gone out and the battery worked perfectly. Skill level: experience. Cost: less than $10. Perhaps it's time for hybrids to be able to test their own cells individually. Dealers, too.

How Toyota's Le Mans racer may make its next Prius even better

The supercapacitor technology in the Toyota TS040 "offers great possibility for production car use." – Amanda Rice, Toyota Pop-culture junkies familiar with 1980s touchstone movies will hear the word "capacitor" and think Back to the Future. But the concept of supercapacitors being used in upcoming production models is being pushed by Toyota, not DeLorean. And because of that push, the future might look a little brighter for the Prius. The Japanese automaker will likely apply electric-motor technology used in Toyota's 24 Hours of Le Mans entry – the TS040 – in future versions of the world's best-selling hybrid, Australian publication Drive.com.au says, citing an interview with Toyota Motor Sports' Yoshiaki Kinoshita. Specifically, the racecar uses supercapacitors because they're effective at storing energy created when the vehicle is under braking, only to quickly redistribute it on demand for rapid acceleration. Kinoshita said Toyota may apply this technology to the Prius within the next five years. While declining to comment on specifics, Toyota spokeswoman Amanda Rice tells AutoblogGreen that the Le Mans vehicle "represents an advanced vehicle laboratory for hybrid vehicle and component development. The supercapacitor technology used in this vehicle with its fast charge and discharge capability offers great possibility for production car use." In her email, Rice added that the next-generation Prius will have smaller electric motors with greater power density and thermal efficiency, so let's add that to what we know or think we know about the fourth-generation model. Toyota entered two vehicles in this year's Le Mans race, and one of them had secured the pole-position and was leading much of the race before calling it quits 15 hours in because of electrical issues. Audi ended up winning the race, marking its 13th victory in the history of the French endurance contest.

Lexus: No plans for LFA replacement anytime soon

Supercars are fantastic in terms of their raw performance, sound and ability to inspire interest in an automaker. They aren't so good at actually making money, even for giant, global automakers like Toyota. And if you are holding out hope that Lexus might be fibbing about there being no plans for an LFA successor, we have some bad news. "I think you will see us do some incredible things in the future, but probably not a $375,000 supercar anytime soon," Lexus Executive Vice President Mark Templin told Automotive News. The issue comes down to the LFA's cost to develop and massive price. Lexus built just 500 of the V10 supercars from 2010 through 2012. Templin said that the plan was originally for a much more modest vehicle with a steel body. However, that intention changed to plans for an aluminum exterior and eventually evolved further to carbon fiber during the course of its engineering. Templin is clear that Lexus isn't giving up on more accessible performance with its F sub-brand models, but more supercars aren't coming, at least not anytime soon. He previously suggested that the LFA was a generational model with a 30-year wait for the next one. These days, the workshop that built the LFA has been converted for a much less powerful but perhaps more important vehicle. Toyota now uses it to build the Mirai with the company's hydrogen fuel cell powertrain.
