(source: CSIRO official website) according to foreign media reports, Australia's national science and Research Organization (CSIRO) has launched new technologies to connect roof solar energy and electric vehicle charging. Even in midsummer, the charging system works well. Now, with more and more electric vehicles on the road in Australia, the demand for infrastructure is also increasing, which puts pressure on the power grid. The new solar electric vehicle charging station can make full use of renewable energy and relieve the grid pressure in peak period. Designed for ordinary Australian homes, these charging stations overcome a range of charging problems for electric vehicles, including managing temperature on the hottest days. With the new technology, you can also charge multiple cars in areas with limited power grid, such as family garages and public parking lots. CSIRO researchers worked with Delta Electronics and Nissan Australia to develop and test the system, and adopted a series of heat management strategies to ensure the effective charging and discharging of the battery. Dr Christopher munnings, chief researcher at CSIRO's hybrid energy systems center, said 90% of electric vehicles can be charged at home. "In a hot day, the ordinary household charging system usually can't charge the car, because overheating will slow down the charging speed. We have designed a way to manage the battery temperature to minimize the demand for grid power. In homes with multiple electric vehicles, the system can automatically monitor each vehicle and distribute loads between batteries, solar photovoltaic and other parts of the home. "This means that the car charges faster and uses as much sunlight as possible without upgrading the grid connection. This technology can accelerate the promotion of electric vehicles. " Nissan's headquarters in Dandenong, Australia, has three solar charging modules, each capable of charging four cars. These modules will be tested and evaluated for more than 200 days, including the summer peak. The researchers will evaluate the data collected throughout the test period to confirm the relevant environmental and cost-effectiveness.
