Saving Power for the Future | ADI
There are a number of ways to incorporate these components into a
full solution, but it is a significant challenge to maximize performance
and minimize the system footprint. This is the reasoning behind ADI's
integration of the analog front end, power control, and monitoring
circuits in a single IC, the AD8452. These ICs can include battery
reversal prevention, overvoltage protection switches, and smart
controls to prevent overcharge of batteries, and they can reduce
the system footprint by 50 percent. This suite of capabilities allows
battery manufacturers to incorporate more capabilities into test
systems that will simultaneously make more efficient use of factory
floor space. Moreover, they allow manufacturers to design systems
with more functionality and more robust testing procedures.
Efficient power conversion is, in turn, another opportunity to drive
further system performance. By using the advanced switching
architectures, test systems can minimize power consumption by
enabling bidirectional energy exchange with the grid. Efficient power
conversion also reduces the need for heat management equipment,
which can add to the system's overall cost and power consumption.
The net result is a reduction in wasted energy and manufacturing
cost. Enabling these capabilities requires an appreciation of system
features, such as isolated gate drivers, that support the faster
switching needs of newer silicon carbide and gallium nitride power
switching technologies.
The benefits of working closely with suppliers who have system-level
expertise and a broad portfolio of products goes beyond having
access to more sophisticated components and building blocks. It
also gives battery manufacturers access to reference designs for
system architectures that can be more easily adopted, making time
to market three to four times faster than if a battery manufacturer
were to develop a formation and test system from scratch.
With the expectation that the global demand for EVs will increase at
a CAGR of 21 percent out to 2021, the need for close partnerships
between battery manufacturers and suppliers couldn't be greater.
Suppliers need to provide reliable, proven solutions that enable
manufacturers' systems to achieve new levels of efficiency. The
best suppliers can help manufacturers bring these new capabilities
to market even faster, and the results will allow battery and electric
vehicle production to flourish.
