How to get incredibly accurate information on your EV's charging power

One would think that paying about $300 to receive a bit of bad news about electric-vehicle charging would be counterproductive. But the fine folks at Teslarati believe that truth is beauty, and they're willing to pay a little extra for the straight dope. There are always losses when taking power from the grid and shoving it into an EV's battery pack. The question is how big are these losses. Teslarati calculated digital read-outs from the dashboard of their Tesla Model S all-electric sedan and found that Tesla builds in about a nine percent efficiency loss when it comes to recharging the car. But the blog thought the Tesla couldn't know exactly what was transpiring between the wall and the battery, so it footed the bill for about $300 to install a digital submetering unit from EKM Metering. With a little calculation, Teslarati was able to figure out after a couple of recharging rounds that the efficiency loss per recharge was closer to 15 percent than nine percent. That means that, instead of paying about 48 cents on the dollar relative to filling up an economy car (factoring in the AAA average price of $3.66 per gallon), Tesla owners are paying about 52 cents on the dollar. Not much compared to paying upwards towards $100,000 for the vehicle itself, but, hey, every cent counts, right? Get all of the details here.

Recharge Wrap-up: Renault Zoe driving video, BYD Buses in Campinas

A new video shows drivers how to get the most range out of the Renault Zoe. By managing one's driving style, as we all know, one can minimize energy consumption. The Zoe's Econometer and R-Link screen give feedback about the rate of consumption, which helps let the driver know that they should hold back in the throttle. The R-Link system shows the distribution of energy in real time. It also analyzes the driving route and gives feedback at the end of the session. The Zoe also has an Eco button that automatically limits consumption regardless of driving style. Pre-programming climate control can also help improve range. These are all features we're more or less familiar with, but see how they work in the Renault Zoe in the video above. Tesla has announced it will release its second quarter results on August 5. After the automaker releases its financial information on that day, it will hold a live question and answer conference call webcast to discuss those results and outlook at 5:30 Eastern. The second quarter ended June 30. Read more at MarketWatch. Campinas, Brazil will add 10 BYD electric buses to its fleet. It is the first city in Brazil to have a zero-emissions bus fleet. Campinas will be using BYD's 39-foot, four-door K9 battery electric bus, but the K11 articulated electric bus will also begin testing in the city soon. Campinas Mayor Jonas Donizete likes the electric buses because "they are very comfortable, almost noise-free, and great for the environment," and they will help reduce the city's air and noise pollution. BYD plans to open factories for electric buses and solar panels in Campinas over the next year, investing about $108.5 million from 2014 to 2017. Read more in the press release below. BYD to Deliver 10 Electric Buses to Campinas Public Transport Fleet 07/22/2015 (Campinas, Brazil): BYD do Brasil and Campinas City Administration announced this month, the addition of 10 battery-electric buses to the city's public transportation bus fleet. Campinas is a city in the interior of the state of Sao Paulo, Brazil, and will be the first in the country to have a fleet of fully electric, zero emission buses operating in its streets. The model chosen to integrate the fleet in Campinas is the BYD K9, a 12-meter, 4-door, low-floor urban bus, with universal accessibility for passengers with limited mobility.

CARB scrapping plan for $60,000 limit on EV rebates

In April, we heard about a discussion within the California Air Resources Board (CARB) that would have put a $60,000 MSRP limit on plug-in vehicles that would qualify for CARB's $2,500 rebates. A new report in Silicon Beat says that CARB is once again ready to give EV money to everyone, no matter what expensive car they buy. There's no question that the CARB proposal would have had an inordinate effect on Tesla Motors, the only company selling a EV expensive enough to cost more than $60,000, the Tesla Model S. Okay, the Cadillac ELR plug-in hybrid would also have been affected, but that only would have applied to a small handful of people. According to Silicon Beat, the updated CARB proposal says clearly that, "at this time staff is not proposing any significant changes to the Clean Vehicle Rebate Project as part of this year's Initial Funding Plan." CARB spokesman David Clegern told Silicon Beat that, "It's fair to say [the $60,000 limit] been removed. I never say anything is dead until after the vote, but I'm not aware of any plans to revisit it." In other words, Tesla, you're good to go. We've asked CARB for confirmation of this, but have not yet heard back.
