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.

2015 will be the biggest year ever for cars at CES

Like the SEMA Show, major automakers are paying increasing attention to the CES, with 2015 expected to be one of the most auto focused yet. Ford, Volkswagen, Toyota, General Motors, Hyundai, Mazda, Audi, BMW and Fiat Chrysler Automobiles will all be in attendance when CES 2015 kicks off next week, taking up a record-breaking 165,000 square feet of space at the Las Vegas Convention Center. "We've come a long way from a single car on a carpet," Ford's Alan Hall told Bloomberg. Unlike SEMA, or a more traditional auto show, like the upcoming festivities in Detroit, CES doesn't necessarily focus on entire cars or the way they perform, but on the way our technology will interact with vehicles, and in how those vehicles will deliver information to drivers. "CES has become a major launch point for a lot of the big automakers," IHS tech analyst Mark Boyadjis told Bloomberg. "CES is a way for them to get on a global stage for technology." As for what kind of wares automakers will trot out in Las Vegas, we already know that BMW will show off an autonomous i3 electric car that can navigate its way through a multistory car park and can be hailed via a smartwatch app. According to Bloomberg, Hyundai will show off its own smartwatch app for the Genesis sedan, while Audi and Mercedes-Benz will show off autonomous vehicles next week. Automakers won't be the only companies looking to capitalize on CES. Tech firms, like chipmaker Nvidia, are becoming increasingly involved in the automotive game and will be in town showing their wares off to OEMs. "Two years ago, our booth would have been filled with PCs and people playing video games," Danny Shapiro, Nvidia's senior director for automotive business, told Bloomberg. "This year we made a strategic decision to shift the focus of the booth on automotive and de-prioritize some of the other things." Needless to say, you can expect to see a lot of news out of Las Vegas come next week. Stay tuned.

Recharge Wrap-up: Renault-Nissan hits 250,000 EVs, will the next Toyota Prius be an SUV?

Will the next Toyota Prius be an SUV? Mazda and Toyota recently reached an agreement to share powertrain technologies, which will help Mazda comply with California's tightening ZEV restrictions with a plug-in vehicle. On the flip side, Toyota will have access Mazda's Skyactiv diesel powertrain, which a source tells Motoring will be used in an SUV based on the Toyota Prius (and, as Hybrid Cars suggests, on the Toyota C-HR concept). Interestingly, the collaboration will also give Mazda access to Toyota's fuel cell technology, which could mean more hydrogen powered cars on the road and the subsequent expansion of hydrogen fueling infrastructure. Could it also make way for a long-awaited hydrogen powered rotary-engine sports car from Mazda? Read more at Motoring. Samsung SDI unveiled two new lithium-ion stationary batteries at Intersolar Europe. In doing so, Samsung throws its hat in the ring with the likes of automakers Tesla and Mercedes-Benz, using knowledge from electric vehicle batteries in the arena of home solar energy storage. In addition to its 3.6-kWh battery, its new 5.5-kWh and 8.0-kWh batteries offer storage solutions at a larger, more practical scale for solar customers. Called the All-in-One, the battery system, borrowed from electric vehicles, is made up of a photovoltaic inverter, battery PCS and lithium-ion battery, and promises efficiency, compactness, fast installation and an affordable price. Read more from Samsung SDI. The Renault-Nissan Alliance has sold its 250,000th electric vehicle. The quarter-millionth EV was a white Renault Zoe sold to a French computer engineer from Bordeaux named Yves Nivelle. While he credits a government program offering a ˆ10,000 rebate for EV buyers trading in an older diesel vehicle for helping him make the decision to pull the trigger on the new Zoe, "I have to say, I was convinced the first time I drove the car. It's a real pleasure to drive and it feels good to do my part for the environment," says Nivelle. The Alliance had sold around 31,600 EVs from January to May this year, up 15 percent from the first five months of 2014. See the video above, and read more in the press release below.
