Electric Construction Equipment Test Solutions
Electric construction equipment includes vehicles that are designed for construction and mining such as tractors, dump trucks, mining trucks, and excavators. Electrifying this equipment requires high performance batteries with extended battery life and fast charging times. Its unique application also requires robust and reliable electric drive systems with high payloads. Test applications range from evaluating charging, battery capacity and performance, to safety and infrastructure requirements.
NHR?s Battery Test Systems are ideal for testing complex battery test profiles in compliance with industry standards. NHR?s Battery Emulator/Simulator is a bidirectional DC source and load that will safely emulate a fast charger, or a high voltage battery that can accept fast charging. Our battery emulators are also ideal for testing the entire powertrain including the electric drive system and motor. The 9300/9200 can accept back EMF and its isolated input and output paths eliminate single points of failure and unstable conditions.
Electric Fork Lifts, Pallet Jacks, Lift Trucks Test Solutions
Electric forklifts, pallet jacks, and lift trucks have large industrial-scale, stationary batteries that require high performance battery chargers. In most cases, these types of chargers and batteries are expensive, quite large and difficult to move. NHR?s Battery Test Systems y Battery Emulators/Simulators are ideal for testing a combination of various batteries and chargers to optimize product performance and to ensure safety.
Our next generation battery test systems are ideal for cycling industrial-scale batteries to test their performance at full power, safely. Its flexible and easy integration with third party tools provides a comprehensive battery test solution. Testing the industrial battery charger or the system requires battery emulation to simulate the characteristics of these large stationary batteries effectively. Using battery emulation instead of real batteries also eliminates operator error and environmental variables such as battery temperature or aging, to achieve precise results. The bidirectional power flow of the battery emulators are ideal for accepting back EMF and safely testing the electric drive and motor.
Electric Power Tools & Machinery Test Solutions
Heavy duty, electric powered tools and machinery require high performance batteries and chargers due to the frequency and high power being used. Our next generation sistemas de prueba de batería are ideal for battery characterization and creating complex test profiles based on its application. Its modular and scalable power as well as its multi-channel configuration options also enables flexibility to reduce testing time.
Applications for charger testing may require simple loading of charges using low power DC loads or higher power testing using our battery emulators (bidirectional dc source and load) to simulate the system. Testing a charger often requires an Fuente de alimentación de CA y un Carga DC. Simulating facility power with NHR’s Regenerative Grid Simulator allows the engineer to adjust the input frequency, voltage, and simulate power line disturbances.
NHR?s battery emulation/simulation capability is ideal for emulating the DC power source for testing the electric drive, charger and related power electronics to ensure overall product performance, safety and compliance.
