Rooftop solar to charge renewable vehicles

CSIRO teams up with Nissan, Delta Electronics for tech to accelerate EV rollout in Australia

CSIRO is trialing solar-powered electric vehicle (EV) charging stations, with the hope that they may be installed in homes, car parks, and garages to alleviate pressure on grid-powered charging stations.

In the Australian climate, battery charging suffers in the heat, with a loss of efficiency that results in more power needing to be drawn from the grid.

While 90 per cent of EV charging is likely to take place in the home, Dr Christopher Munnings, the lead researcher at CSIRO’s Centre for Hybrid Energy Systems, explains, “A normal household battery system is typically not powerful enough to charge a car on a hot day as it can overheat and slow down.” 

CSIRO researchers have come up with the solution to link rooftop solar and batteries to support EV charging, leveraging the increased sunlight that comes with summer. 

Funded by the Victorian Government and in collaboration with Nissan Australia and Delta Electronics, the charging stations can charge up to 4 vehicles at a time.

Munnings says, “We've devised a way to manage the temperature of the battery, minimising the amount of power required from the grid. In a multi-EV home, this system will automatically monitor each car, spreading the load between the battery, solar PV and the rest of the home. This means the cars charge as quickly as possible, using as much sun as possible, without the need to upgrade grid connection. This technology could accelerate the widespread rollout of EVs across the country."

An increased uptake of EVs in Australia could save households money, reduce the risks that come from Australia’s fuel security, and improve the health of residents. 

A recent Senate inquiry heard that electric vehicles are 70-90 per cent less expensive to work, sparing families more than $2,000 every year. Investment banking firm UBS has estimated that the total cost of ownership for EVs relative to internal combustion engines will be $5000 less by 2021, and $11,000 less by 2025 as battery prices fall.

Another advantage is fuel security, with Australia heavily reliant on imports to meet demand. Australia currently has 27 days worth of fuel reserve in the case of emergency. A faster shift to electric vehicles will negate some of the dangers in a catastrophic event.

An increased uptake of EVs will have health benefits, as vehicle pollution causes an expected 40% to 60% more premature deaths than road accidents in Australia, with electric vehicles giving a pathway to cut down on dangerous air particulates.

Currently, 3 solar powered chargers have been installed in the Nissan Headquarters, which will be evaluated and tested for 200 days. After the trial, the project partners will confirm whether heat management strategies are working and if batteries are sufficient, after which the cost benefits can be evaluated. 

Nissan Australia managing director Stephen Lester said “Nissan is proud to partner with CSIRO and Delta Electronics to deliver this innovative trial and acknowledges the investment of the Victorian Government in supporting this project."

In 2016 I published a blog article titled Moonshots for Australia: 7 For Now. It’s one of many I have posted on business and innovation in Australia. In that book, I highlighted a number of Industries of the Future among a number of proposed Moonshots. I self-published a book, Innovation in Australia – Creating prosperity for future generations, in 2019, with a follow-up COVID edition in 2020. There is no doubt COVID is causing massive disruption. Prior to COVID, there was little conversation about National Sovereignty or supply chains. Even now, these topics are fading, and we remain preoccupied with productivity and jobs! My motivation for this writing has been the absence of a coherent narrative for Australia’s business future. Over the past six years, little has changed. The Australian ‘psyche’ regarding our political and business systems is programmed to avoid taking a long-term perspective. The short-term nature of Government (3 to 4-year terms), the short-term horizon of the business system (driven by shareholder value), the media culture (infotainment and ‘gotcha’ games), the general Australian population’s cynical perspective and a preoccupation with a lifestyle all create a malaise of strategic thinking and conversation. Ultimately, it leads to a leadership vacuum at all levels. In recent years we have seen the leadership of some of our significant institutions failing to live up to the most basic standards, with Royal Commissions, Inquiries and investigations consuming excessive time and resources. · Catholic Church and other religious bodies · Trade Unions · Banks (and businesses generally, take casinos, for example) · the Australian Defence Force · the Australian cricket teams · our elected representatives and the staff of Parliament House As they say, “A fish rots from the head!” At best, the leadership behaviour in those institutions could be described as unethical and, at worst….just bankrupt! In the last decade, politicians have led us through a game of “leadership by musical chairs” – although, for now, it has stabilised. However, there is still an absence of a coherent narrative about business and wealth creation. It is a challenge. One attempt to provide such a narrative has been the Intergenerational Reports produced by our federal Government every few years since 2002. The shortcomings of the latest Intergenerational Report Each Intergenerational Report examines the long-term sustainability of current government policies and how demographic, technological, and other structural trends may affect the economy and the budget over the next 40 years. The fifth and most recent Intergenerational Report released in 2021 (preceded by Reports in 2002, 2007, 2010 and 2015) provides a narrative about Australia’s future – in essence, it is an extension of the status quo. The Report also highlights three key insights: 1. First, our population is growing slower and ageing faster than expected. 2. The Australian economy will continue to grow, but slower than previously thought. 3. While Australia’s debt is sustainable and low by international standards, the ageing of our population will pressure revenue and expenditure. However, its release came and went with a whimper. The recent Summit on (what was it, Jobs and Skills and productivity?) also seems to have made the difference of a ‘snowflake’ in hell in terms of identifying our long-term challenges and growth industries. Let’s look back to see how we got here and what we can learn. Australia over the last 40 years During Australia’s last period of significant economic reform (the late 1980s and early 1990s), there was a positive attempt at building an inclusive national narrative between Government and business. Multiple documents were published, including: · Australia Reconstructed (1987) – ACTU · Enterprise Bargaining a Better Way of Working (1989) – Business Council of Australia · Innovation in Australia (1991) – Boston Consulting Group · Australia 2010: Creating the Future Australia (1993) – Business Council of Australia · and others. There were workshops, consultations with industry leaders, and conferences across industries to pursue a national microeconomic reform agenda. Remember these concepts? · global competitiveness · benchmarking · best practice · award restructuring and enterprising bargaining · training, management education and multiskilling. This agenda was at the heart of the business conversation. During that time, the Government encouraged high levels of engagement with stakeholders. As a result, I worked with a small group of training professionals to contribute to the debate. Our contribution included events and publications over several years, including What Dawkins, Kelty and Howard All Agree On – Human Resources Strategies for Our Nation (published by the Australian Institute of Training and Development). Unfortunately, these long-term strategic discussions are nowhere near as prevalent among Government and industry today. The 1980s and 1990s were a time of radical change in Australia. It included: · floating the $A · deregulation · award restructuring · lowering/abolishing tariffs · Corporatisation and Commercialisation Ross Garnaut posits that the reforms enabled Australia to lead the developed world in productivity growth – given that it had spent most of the 20th century at the bottom of the developed country league table. However, in his work, The Great Reset, Garnaut says that over the next 20 years, our growth was attributable to the China mining boom, and from there, we settled into “The DOG days” – Australia moved to the back of a slow-moving pack! One unintended consequence of opening our economy to the world is the emasculation of the Australian manufacturing base. The manic pursuit of increased efficiency, lower costs, and shareholder value meant much of the labour-intensive work was outsourced. Manufacturing is now less than 6% of our GDP , less than half of what it was 30 years ago!
