High precision dual channel programmable battery simulator N8352 series

The high-precision dual channel programmable battery simulator N8352 series is a specialized testing instrument designed for the research and testing of portable battery powered products. N8352 series current flows bidirectionally, and the power supply and load operating states can be quickly switched; The output characteristics can be comparable to real batteries, with fast dynamic response characteristics, no overshoot in voltage rise and fall, and stable waveform; Function *, supports multiple testing functions such as power mode, charging mode, battery simulation, internal resistance simulation, SOC simulation, fault simulation, etc

N8352 has the following core functions:

Power mode: As a two channel power supply, it can set the output voltage and output current limit value, automatically switch between constant voltage mode or constant current mode according to the load status, multiple current ranges, and improve output and measurement accuracy.

Battery simulation: N8352 dual channel can independently set initial voltage value, internal resistance value, battery capacity and other battery related parameters, and perform real-time feedback on them. Used to replace the difficulty of controlling battery parameters in testing with real batteries, and improve the efficiency of testing and development.

Fault simulation: In addition to the normal state of the battery, the following fault states of the battery can also be simulated: open circuit of positive and negative poles, reverse connection of positive and negative poles, and short circuit of positive and negative poles.

Current flows in both directions, serving as both a power source and a load
(1) Current flows in both directions, and the same device can draw in and output current under the same connection method.

(2) There is a switch component at the output end, which is physically connected to the external circuit when it is turned off.

DVM testing function

In addition to providing battery simulator function, the N8352 series also offers basic circuit measurement function. It is equipped with two high-precision DVM digital voltmeters to test external voltage, with a voltage range of -30V~30V and a display resolution of 0.1mV. The display data is refreshed in real-time on the touch screen, making it convenient for users to directly observe voltage changes.

Variable output impedance, realistic simulation of battery internal resistance

N8352 has battery internal resistance simulation function and supports programmable internal resistance values, with a programmable range of 0-20 Ω, which can simulate the change curve consistent with the actual battery internal resistance characteristics. The principle of N8352 and battery is shown in the figure:

Ultra fast transient response without overshoot, comparable to real batteries

The N8352 series can ensure that there is no overshoot in voltage changes, whether under no-load or loaded conditions, to prevent damage to the tested product caused by voltage overshoot and over discharge, thereby affecting product quality. Can meet the testing requirements of products with strict power supply requirements.

The battery simulation feature allows for the creation of battery models of any size

The N8352 series battery simulator supports various battery simulation functions and features such as power mode, charging mode, battery simulation, SOC testing, SEQ editing function, fault simulation, etc. One instrument can achieve multiple purposes, streamline testing equipment, and optimize testing processes. N8352 can test standby static power consumption, create battery models of any specification, with * protection function, and no battery safety hazards and risks.

Mobile application testing

Most consumer electronics products on the current market require lithium-ion batteries for power supply, especially in the smartphone industry where battery life issues are becoming increasingly prominent. Testing mobile phone batteries is also becoming more stringent. Compared to real batteries, using simulated batteries for testing has the following advantages: it can simulate battery change curve characteristic models, shorten testing cycles, and improve the reliability of test data through repeated testing of established models.

Both channels of N8352 can be charged and discharged, so either channel can be used as a power source, while the other channel simulates a battery and is connected to the power and battery terminals of the tested phone without changing the wiring, allowing for testing of the phone's battery charging and discharging performance. A single machine can be used to test a charging and discharging protection board without the need for additional switch switching, greatly simplifying the complexity of the testing system and improving the stability and efficiency of testing.
