This means a whole new sets of inivations for capacitors just to meet the demands of the HEV market.
It's not just an issue of super capacitors, which are a type of capacitors, but a greater demand on efficiency and tolereance and all other know parameters of the capacitors in general, which have to be improved upon to meet the demands of HEV.
It's a whole new market opening up and i'm sure both the supply chain and OEMs are up to the task.
“Then there is the issue of EMI and power quality. Filters and conservative design will be the rule. What all this points to is conservative design rules, the use of high-quality components, and failsafe/redundant architecture. What does it mean for capacitors?” Can you suggest some of the issue with Emi and power quality? Any way the Emi varies with the size and the time taken for charging. This can happens, while discharging also. The main two equation connected with capacitor are T=RC and f = 1/2πRC
In terms of super caps, I am interested to know more about the market itself. How big is the market and who are the players? Making super caps for HEV is definitely not easy when there are lots of safety regulations to go through.
Electric vehicles use lithium-ion rechargeable batteries. Very sophisticated charging systems count the charge going into and coming out of the batteries. Supervision circuits measure currents to several digits of accuracy and time to milliseconds (1/1000 seconds) to know what is the state of charge. Voltage monitoring and temperature gives information on aging capacity of the battery. To keep the charger high efficiency a switching power supply is used with its own active power factor correction circuit. To match a traditional 60 hp engine it requires 44.7 kW electric motor. This is a small power plant inside each electric vehicle, which typically has over 100 kW electric motors.

Peter Drucker famously said "Trying to predict the future is like trying to drive down a country road at night with no lights while looking out the back window." Yet in the razor's-edge world of electronics—with a lean supply chain and just-in-time demands—the need to know the future is vital.
You've heard the saying "the No. 1 supply chain risk is your people." That hasn't always been the case. But today's complex global supply chain requires a new type of multitalented employee. It's one who understands, finance, marketing, economics, is savvy with technology, graceful with relationships and can think analytically.
Where are these people? Are universities properly preparing the next generation supply chain professionals? How do train your existing workforce for these new, demanding positions?
Brian Fuller, editor-in-chief of EBN, will lead a 60-minute Avnet Velocity panel discussion that will ask and answer these and other questions swirling around today's supply-chain talent challenges.
