Product Description

Battery Management System (BMS) Validation Test Instrument BMS tester
N83624 Series High-accuracy Multi-channel Battery Simulator

A battery simulator is an electronic equipment that emulates numerous  properties of a real battery. These properties are power, voltage, current,  etc. The battery simulator supplies the required voltage, power, and current to the mobile device in the same manner as an actual battery. In a way, a simulator is a programmable electronic battery.

Product Introduction
N83624 is a programmable battery simulator with low-power, multi-channel and high-accuracy, suitable for BMS/CMS test. It is highly integrated, single device with up to 24 channels. Each channel is isolated. Users can set the voltage & current for each channel on application software, which is easy to use and can meet the needs of multi-channel and multi-data. The software can also provide graphs, data analysis and report function. N83624 is equipped with high-definition color LCD screen, available for local operation.

Advantages
Safety
The battery contains high energy storage. Under normal conditions, such as temperature, charge rate, and discharge rate, engineers can use the battery safely. However, some unexpected situations may occur during the test. During the design phase, the DUT may not work properly and cause the battery to be overcharged or over-discharged. Moreover, the DUT may malfunction or enter an unexpected state, which may absorb excessive current from the battery, resulting in fire, explosion, chemical leakage and other risks.
The battery simulator includes electronic protection circuits, such as overvoltage and overcurrent protection, which will interrupt the test when a problem occurs during the test.

Repeatability
Generally, by fully discharging the battery and then charging the battery to the desired state of charge, this will accelerate the battery aging and shorten the battery life. Battery performance will decrease over time. Engineers cannot guarantee that aging batteries will be charged to the required state of charge. Therefore, testing with aging batteries may lead to incorrect results.
Compared with testing with real batteries, battery simulators can obtain more consistent and repeatable test results. It eliminates the uncertainty associated with battery aging and can determine the state of charge of the battery.

High Efficiency
Usually, it takes several hours to fully charge a real battery. To improve test efficiency, engineers can use the battery simulator to quickly change the voltage to simulate the battery being charged, instead of waiting for the charger to charge the real battery.

Ultra-high accuracy
N83624 current resolution is as low as 0.1μA. Ultra-high accuracy, ultra-low ripple and noise index make N83624 an ideal choice for battery simulation application. The ultra-high accuracy of N83624 output and measurement can be directly used in product calibration and test, eliminating the use of external high-accuracy measuring instruments and saving cost for users.

Ultra-high integration
N83624 integrates up to 24 channels that can be connected in series mode in 19-inch 3U size, providing a compact solution for ATE test systems in BMS, CMS and similar large-scale high-density production sites.

Battery simulation suitable for BMS chips test of various specifications
N83624 series battery simulators have multiple functions and features, supporting Source, All CH, Charge, SOC Test, SEQ, Graph, etc.
One device can achieve multiple uses, streamline test equipment and optimize test procedures. N83624's internal circuit is optimized for different chips, which can be adapted to test BMS chips of various specifications.

Fast dynamic response
N83624 series has fast dynamic response capability. The response time of load varying from 10% to 90% and voltage recovering within 50mV of previous voltage is less than 100μs, which can ensure the rising waveform of voltage or current is high-speed and without overshoot, and provide stable power for the DUT. This feature can meet the demand for product test with strict power requirements.
