We are an Authorized Design House for Microchip Technologies. Using low power embedded solutions we can create customized power management systems to meet your needs.

Custom Charger for Telecom Batteries

• High powered 100 bay charging system with air conditioning and safety interlocks.

• 50.4V Li-ion charger at 90W power per bay.

• Smoke and over temperature lockouts.

• 208 to 240VAC powered.

• CAN and I2C interfaces for data collection.

Custom Chargers for Medical Batteries

• racks of 5-Bay "Warehouse charger" for lease-return batteries

• System charges-discharges batteries, measures actual capacity and pass/fails batteries,

• connects to back-end database and allows operator to pass/fail based on cosmetic or physical damage to packs,

• System logs operator via fingerprint scanner to meet FDA requirements for traceability,

• Barcode logs battery serial numbers,

• Fanless, all convection and conduction cooled.

--------

• 20 bay rack mount charger for small Li-ion medical batteries. All convection cooled.

• Charger performs a discharge resistance test of the battery and reports pass/fail of charge and test through RS485 interface. Up to six 20 bay chargers can be chained together on a single RS485 interface.

• PC control mode allows PC based software to control each charger bay to perform customized tests.

Battery Cycler for Enterprise Server Manufacturer

• Battery cycler that supports charge and discharge to a target capacity.
• Features removable contact plates.

• Entire product built in-house including PCB population and assembly, laser cutting of top housing and CNC machining of main housing.

Portable Chargers for Wearable Sensors

• 24 bay wearable sensor charger with its own 86Wh internal battery for charging away from wall power.

• Spring loaded 3D printed sensor holders allow contact to be made while a bi-colour LED indicates charging status for each bay.

---------

• Two bay battery charger for a wearable sensor. 3D printed insert in off the shelf case. Everything is included, wall adapter, cord, and storage for adhesive pads.

• Internal 2800mAh pre-certified battery allows the case to charge the sensors when away from mains power.

• Bi-color indication of charging for the sensors with a 5 LED fuel gauge to show status of internal battery.

Serial Interface for Reprogramming Chargers

• Custom USB to I2C serial interface with galvanic isolation for reprogramming an existing charger system for new battery firmware.

• System identifies charger and applies update to each bay of the charger.

• Using a custom serial interface allows a low latency fast update of the charger firmware compared to an off the shelf solution.

• PC program programmed in Python + QT for rapid development and cross platform release
