China-made on-board charger (OBC) is priced at RMB1,000-4,500/unit for the moment. The larger power it is, the higher price will be. OBC falls into three types by power: <2.5KW, 3-5KW (mostly 3.3KW), and >6KW, respectively for EVs with battery capacity less than 15kWh, 15-24kWh electric passenger cars and small logistics vehicles, and 24kWh-above electric commercial vehicles and logistics vehicles. Market price of 6.6KW charger stands at RMB3,500-4,500, 3.3KW at RMB1,500-2,000 and 2KW at around RMB1,000. Large power OBC is growing a trend as individual users and ride-hailing firms require far shorter charging time. 6.6KW OBC will win popularity; 10KW-23KW large power ones will find wider application. By RMB3,500 per unit, the OBC market size will be RMB7 billion in 2020; the DC/DC market will be valued at a staggering RMB3 billion in 2020 as long as the price of DC/DC converter is kept at RMB1,500.

SiC MOSFETs are available as 1200-V, 20-A devices with a 100-mΩ RDS(ON) at a +15-V gate-source voltage. Besides the inherent reduction in on-resistance, SiC also offers a substantially reduced on-resistance variation over operating temperature. From 25 to 150°C, SiC variations are in the range of 20% versus 200% to 300% for Si. The SiC MOSFET die is capable of operation at junction temperatures greater than 200°C, but are limited by its TO-247 plastic package to 150°C. The technology also benefits from inherently low gate charge, which enables high switching frequencies to be used, allowing for smaller inductors and capacitors.

Charge all laptops, cellphones and any other device that uses rechargeable batteries. Think about purchasing a backup charger and get that ready, too.

“The cost of products have gone down drastically,” said Melinda Kershaw, director of marketing for Day & Night Solar in Collinsville, which designed both systems. “The cost of labor has gone down, and the panels have increased in production.”

"With a steadily growing share of renewable energies, hydrogen fuel cells could play a role in the future," said a Ford spokesman. "In terms of a widespread market launch, however, the battery is currently in a superior position to the fuel cell – not least because of the cost situation and the available infrastructure. Our work will continue to focus on electrification as we monitor hydrogen’s progress. We have no current plans to offer hydrogen fuel cell vehicles."

"Considering that more than 30 MXenes are already reported, with more predicted to exist, there is certainly much room for further improving the electrochemical performance of battery electrodes by utilizing other materials from the large MXene family," he said.

China is now home to the largest floating solar farms in the world, concentrated in Anhui Province atop flooded former coal mines. The biggest floating solar farm can produce 150 megawatts (MW). Estimates vary widely on how many homes one megawatt can power based on a variety of factors such as geography and weather, but the California Energy Commission pegs the number at 750 homes. Our advanced math skills tell us that a 150-megawatt solar power plant can support about 112,500 residences. Of course, China is not California, so either double or half the number, depending on your personal biases.

Industry analysts forecast the global electric vehicle power electronics Market to grow at a CAGR of 18.62% during the period 2017-2021.

With primary currents of this magnitude, the design of the PCB on which the transducer is mounted is important. Simulations have shown that with an optimized design the temperature rise in the transducer due to a 35 A primary current is limited to a 13o C increase.
