Power supply mode similar to computer motherboards. Application of large gold capacitors for effective resistance to external power grid interference. Multiple independent power supply technology to reduce interference between channels. Temperature coefficient of 5ppm/°C (maximum). Military-grade communication chips for stable and reliable data exchange. Data rate: 500kbps. Maximum bus connection quantity: MAX256 units. Optical isolation between each device. 24-bit ADC; 16-bit DAC. Voltage and current testing accuracy reaching the highest domestic precision of ±0.02% (minimum error). Data sampling frequency of 10 points/second (fastest effective data). Product Features: The front panel is crafted from a single piece of aluminum with an oxidized sandblasting process, and the chassis is made from galvanized plate with a spray coating process, resulting in an exquisite appearance. The battery testing chamber is integrated with the device to prevent external interference during testing. A 3-inch custom LCD display on the left side of the front panel shows device information (box number, voltage range, current range, communication status, channel number, etc.). The brightness is adjustable, and the display is synchronized with the device’s main control board. The output ports use all-metal connectors, and the port socket features a ring of lights in seven colors, reflecting the current working state of the tested battery in different colors (e.g., red for charging, green for discharging, orange for standby, white for test completion, yellow for protection stop, etc.). The BT2018AS main unit CPU adopts a 32-bit ARM series chip, with separate CPUs for the LCD display and the ring of lights. The DA/AD analog-digital control chip is 16-bit/24-bit. The temperature coefficient is 5ppm/°C (maximum). The actual output accuracy is ±0.01% FS, and the data sampling frequency ranges from 3 to 10 points/second, with a maximum of 10 points/second. Currently, it is the highest precision and fastest sampling speed in China.
