Applications

NHR’s 9300 high voltage battery emulator, or simulator, includes power ranges from 100kW up to 2.4MW. This innovative battery emulator addresses the higher voltage and higher power battery test requirements for electric vehicles, renewable energy storage, solar PV inverters, aerospace and other critical power industries.

NHR’s 9300 battery pack battery emulator is highly configurable and provides dual voltage ranges of 600V or 1,200V. It can be paralleled up to 24 building blocks to get 2.4MW of power and up to 8,000A of current. Key differentiating features from other battery emulators, or simulators on the market include high accuracy, modular and scalable power, safety and ease of use.

The High-Voltage Battery Emulator (9300 Series) is a fast-acting, fully programmable, and bi-directional DC source (charge) that provides reversible current flow in order to act as a regenerative DC load (discharge). Both modes support any combination of constant power, constant voltage, and constant-current regulation limits.

Accurate Battery Emulation

Unlike other battery emulators on the market, NHR’s battery emulators have a built-in programmable series resistance with low-capacitance. Battery emulators with low output capacitance provide accurate simulation of series resistance effects, allowing the output voltage to adjust proportionally to changes in current. By comparison, many regenerative power supplies have high output capacitance to reduce noise output. This high output capacitance disrupts the series resistance models and actually negates the functionality of a programmable series resistance. As a result, high output capacitance can lead to inaccurate battery simulation.

For more information about battery emulation, see our Battery Emulators page.

Modular & Scalable Power

All NHR battery emulators are designed for fully independent operation and can be paralleled, increasing the maximum power and current capability to the level required. This modular expansion ensures that you can start testing today’s application levels, knowing that additional power is available in the future. Expansion of the 9300 system is as simple as adding an additional cabinet(s) to reach the desired power levels up to 2.4 MW.

Wide Operating Envelope

NHR’s 9300 Battery Emulators provide the flexibility to address today’s higher voltage levels, and modularity to expand for future requirements. Customers are able to simulate a wide range of battery power levels without having to change test equipment. New electric transportation architectures are now operating between 800/1000 VDC to enable faster DC charging. The 9300 has a dual power range that covers both lower (up to 600 V) and higher power (up to 1200 V) applications using a single product. Unlike custom built solutions, the 9300 provides maximum flexibility in voltage and power, providing full power from 300 V – 1,200 V.
