FAQ
Is the NH Research (NHR) 9300 battery test system being discontinued?
As best as can be determined from public sources, yes. NH Research’s product lines are now sold under NI (National Instruments) branding, and NI was acquired by Emerson in 2023. A third-party upgrade vendor and an independent NHR distributor both point to the same general window — standard service ending around late 2025 into 2026 — though neither is a confirmed statement from NI/Emerson directly. Treat the exact date as a strong lead, not a fact, until a primary NI/Emerson source is found.
Why is NH Research discontinuing the 9300?
The 9300 is part of NH Research’s legacy lineup, folded into NI’s portfolio and then Emerson’s after the 2023 acquisition. Legacy NH Research hardware doesn’t fit the acquiring companies’ go-forward test-equipment roadmap, so it’s being sunset rather than carried into new engineering investment — a portfolio decision, not a safety recall.
What does PPST Solutions offer as a replacement for the NHR 9300?
The SmartTS-BT Battery Test System — a rack-integrated, bidirectional battery emulation and test platform for EV/ESS battery development, covering module-level through full pack validation, BMS/HIL testing, lifecycle testing, and second-life evaluation.
How does SmartTS-BT's power ceiling compare to the 9300's?
The 9300 scales to roughly 2.4 MW (24 building blocks of 100 kW each, 8,000A total). SmartTS-BT scales higher — up to 2.7 MW from a single 270 kW cabinet, parallelable up to 10 cabinets — reaching a higher ceiling with fewer, larger building blocks to manage for the same aggregate power.
Does SmartTS-BT cover the same voltage range as the 9300?
It covers a wider range on both ends. The 9300 offers two fixed voltage ranges, 600V or 1200V. SmartTS-BT offers two models spanning 333–1000 Vdc and 500–1500 Vdc — extending lower and higher than the 9300’s range — with true autoranging that holds full rated power down to 33% of a model’s rated voltage, so the full window is usable without range-switching.
Is SmartTS-BT's battery emulation more advanced than the 9300's?
The 9300 emulates batteries with an open-circuit-voltage-plus-series-resistance model. SmartTS-BT emulates internal resistance directly through a programmable series-resistance (Rint) term layered on top of voltage and current control, rather than relying on a static set point.
Is SmartTS-BT as efficient and regenerative as the 9300?
Both are regenerative, four-quadrant systems that return absorbed test energy to the facility instead of dissipating it as heat. The 9300 publishes over 90% regenerative return; SmartTS-BT is rated up to 96% efficiency.
What control and automation options does SmartTS-BT offer?
Every cabinet ships with a ready-to-run touchscreen GUI — gauges, digital readouts, real-time trending, usable locally or remotely — plus a fully open control layer as standard: Ethernet/SCPI, CAN/CAN FD, and digital I/O. Labs already running LabVIEW, Python, or their own test executive can integrate directly, without rewriting scripts or retraining operators.
Does SmartTS-BT have a touchscreen interface, or do I need a separate computer to run it?
Every SmartTS-BT cabinet ships with a built-in touchscreen GUI — gauges, digital readouts, and real-time strip-chart trending — usable directly at the unit or remotely over the network, with no separate control PC required for basic operation. The same screen’s underlying control layer (Ethernet/SCPI, CAN/CAN FD, digital I/O) is open if you’d rather drive it from LabVIEW, Python, or your own test executive instead.
What safety features does SmartTS-BT include?
Layered protection built around contactors, pre-charge sequencing (matching supply voltage to battery voltage before closing contactors), reverse-polarity/connection detection, and a continuous communication watchdog — standard on every cabinet, not optional add-ons.
Who should I talk to about replacing a 9300?
Contact a PPST Solutions applications engineer with your current 9300 configuration and test requirements. They can confirm fit, walk through the transition, and flag anything on the SmartTS-BT side still finalizing before you commit.
