Application

The CT-211 Easy Charger Wizard is a flexible kit to make your AE / AEK Power converters a versatile three stage battery charger, which can easily fit all frequently used battery types and different battery voltage (12/24/48).

The Cotek AE-800, AE-1500 and AEK-3000 power supplies already have some of the most advanced features of power supplies in their class.  The ability to control output voltage and output current limit from 0 – 108% either through analogue or digital (I2C) control, coupled with a true constant current, current limit, make the AE / AEK products extremely flexible and ideally suited for charging both Lead-acid and Lithium-ion battery technologies.  In fact, a whole range of batteries and strings can be controlled using a 60 V AE / AEK product with charge currents from 1A to 250A.  Typical applications include:

  • Electric Vehicle charging
  • Industrial automation
  • Robotics
  • Marine
  • Mobile data storage

Programming made easy

Cotek have released a plug-in interface module and GUI which enables users to program the AE / AEK family as true 3 stage battery chargers.  The CT-211 is a small interface which plugs into the auxiliary connector of the power supply and can be programmed via an RS232 or RS485 interface.  The CT-211 has a built in EEPROM to hold its program.

A stand-alone GUI firstly reads details of the connected power supply and then gives users options to either read the software installed on the interface, download a saved protocol, or to create a unique charge program

The GUI allows is broken down into 3 main charge areas: Bulk, Absorption & Float.  The user has full control of voltage, current and time during each of the 3 phases.

These features are extremely powerful especially in the field of Electric Vehicle charging.  One power supply can be easily programmed to charge a variety of different batteries, simply through the upload of new firmware.
