Cotek AE/AEK battery charging with CT-211 Easy Charger Wizard
02 August 2019
Would you like the ability to charge different batteries technologies, sizes and voltages all from the same power supply? Cotek’s new Easy Charger Wizard gives you just that.
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:
• EV (electric vehicle) charging
• Industrial automation
• Mobile data storage
Programing 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.
Features of the family
The AE and AEK family of converters have the following features which make them the ideal choice for rugged battery charger applications:
• Universal input (90-264Vac)
• PFC design with high power density and efficiency (up to 93%)
• High Voltage (60V) / Current (250A) charging capability
• RS232/485/I2C communication
• Programmable and storable charge settings
• Operation temperature -20°C to 70°C
• Safety to UL, TUV, and CB standards
• EMI conduction & Radiation: Certified to EN55032
Relec Electronics have stock of the AE and AEK series products as well as the CT-201 and CT-211 interfaces and are more than happy to give users a demonstration of the power of the system.
