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.Active/passive balancing test
By bidirectional design, current input and output directions of each channel can be respectively controlled. Users can customize the battery charge and discharge model, which fully meets the requirements of BMS active balancing test.
Ultra-high accuracy, supporting static power consumption test
N8358 has high current accuracy, up to 1μA. By supplying power to the DUT, static power consumption of the DUT in standby mode can be intuitively tested. The unqualified products are screened out to ensure the product standby time is within the nominal range after delivery.
Ultra-high integration, built-in fault simulation
N8358 integrates 8 channels in 19-inch 2U size. Each channel has built-in positive & negative polarity short circuit, open circuit, and reverse polarity. Users can control directly on the front panel or on PC. The application of N8358 can eliminate use of external component for battery fault simulation, which can save cost and space for users.
Application-ATE Test
Advantages
N8358 standalone has 8 channels with each channel isolated. Each channel can be used for current input or output. In ATE (Automatic Test Equipment) test system for consumer electronics such as smart phones, Bluetooth headsets, etc., the single production line often uses four stations. During the test, four channels are used as power supply to provide high-accuracy and stable power output. The left four channels are used for battery simulation. Paired channels simulate various operation conditions to check if they can meet the built-in graph requirements. N8358 standalone can be built into a four-station test system, which greatly improves the test efficiency and saves the investment.
