PRODUCT DETAILS

The EV2300 is a USB-based interface board for a PC that can be used to evaluate battery fuel gauge circuits designed with Texas Instruments' ICs. The EV2300 has connections on it for a USB cable and also accepts inputs from a battery fuel gauge circuit's communication port (SMBus or HDQ). By running the appropriate PC software for the corresponding fuel gauge IC, the EV2300 interface board allows the user to evaluate the battery fuel gauge circuit.

DETAILS

USB-based interface board for evaluation of battery fuel gauge circuits developed with fuel gauge ICs using the HDQ and SMBus communication protocol.

Provides interface between intelligent battery circuit and a Windows-based PC.

Connects to the USB port of a PC.

Allows for on screen display and programming of gas gauge register functions when used with the appropriate PC software.

Professional Laptop Battery Analyzer (NLBA) is a hardware and software product developed by NLBA1 team which can be used to diagnose, charge and discharge almost all laptop batteries on the market. The device is capable of reading battery information even the battery is not detected by the laptop, it is faulty or it is over discharged. It is also capable of reading each cell voltage for these kind of non working batteries. It has another great feature to revive over discharged batteries manually or automatically by pressing one button. By discharging the battery with a constant current it can be easily analyze which cells are unbalanced or have a higher internal resistance helping in replacing them to avoid a complete battery failure. NLBA can also be used to measure the real capacity of a laptop battery.

Professional Laptop Battery Analyzer major features are the following:
– reading inner battery information stored inside the battery controller
– reading inner battery information even the battery is over discharged (not detected by laptop, faulty, not powered microcontroller, etc)
– capable to generate variable voltage pulses to revive the battery if it is over discharged
– track each cell voltage by applying a constant discharging current, so unbalanced cells or cells with a higher internal resistance can be easily detected
– calculating battery Health
– charging battery with a lot of custom parameters
– discharging battery with a lot of custom parameters
– displaying correct cell voltage
– calibrating / auto cycle with many options
– checking each cell separately and displaying which are GOOD, POOR or BAD
– calculating the internal cell resistance based on a special algorithm
– measuring the real capacity of the battery by discharging it from Fully Charged to Fully Discharged
– the hardware device can charge the battery with a maximum current of 3A and discharge the battery with maximum current of -3A
– it has built in reverse polarity protection (if battery cable is connected incorrectly)
– it has built in short circuit protection on the output connector
– it has hardware protection against connecting data lines (SMCLK and SMDAT) to battery V Bat
– it has current limit and over temperature protection

Description

The EV2400 EVM interface board enables an IBM-compatible or other type PC (with the required driver for its particular platform) to communicate with the Texas Instruments SMBus and I2C interface gas gauges via a Universal Serial Bus (USB) port. In addition to this board, PC software is required to interpret the gas gauge data to complete the evaluation system.

EV2400 Controller
The EV2400 controller is an MSP430F5529 running at 4 MHz. The controller firmware is stored in flash memory and is executed by the core at power-up.The controller communicates with target device(s) through either: a 2-wire SMBus communication port, a 2-wire EEPROM I2C port, or a single-wire HDQ port. The 2-wire SMBus communication port supports both SMBus and I2C protocols. CRC-8 checksum verification for the data packets prevents data corruption over the USB.
USB Interface (USB)
The interface board connects to a USB port (version 1.1 or later) on a host computer and is powered from the port. All communication over the USB is human Interface device (HID) class. Drivers are built into EV2300 EVM Interface BoardWindows® and most of the operating systems.
