Custom design and manufacture of state-of-the-art
battery chargers, UPS, and power supplies for OEMs in a hurry?
This is a microprocessor controlled DC/DC converter which can be used as a
solar charge controller for lithium-ion, Nickel-Cadmium, and Nickel metal hydride batteries. It
also has serial communications and is programmable with great flexibility.
Serial communications allows
you to control voltage, current, or power remotely, or to select on-board programs.
Very flexible input and output voltages available
Can be used as a solar charge controller for a wide variety of cell counts and
Can use locally to the battery to boost voltage after a long wire run, for example
Output voltage can be higher or lower than the input voltage.
State-of-the-art charging algorithms available for a variety of battery chemistries
Also useful in other energy harvesting applications since it can be programmed to
use whatever power is available, unlike other battery charging circuits.
and output voltage and current sense can be read by the on-board microcontroller. Other A/D and
digital input pins are available to adapt to your needs, for example battery charge termination
measurement, capacity testing, battery quality testing, electrolysis, sensor control, etc.
Form factor and custom features can be designed to OEM
This product is a platform that can be programmed to meet your
system requirements. Typical programming fees are $500 to $2000 depending on complexity and
