Product Description
High-Voltage PT Temperature Sensor for Battery Thermal Management Systems
Overview
The High-Voltage PT Temperature Sensor is a critical sensing component within the Knock-Down (KD) assembly of advanced Battery Thermal Management Systems (BTMS) used in electric buses, commercial EVs, and energy storage platforms. Specifically engineered for high-voltage environments up to 1,500 VDC, this PT (Platinum Resistance Thermometer) sensor delivers precise, stable, and reliable temperature monitoring of battery cells, modules, busbars, and cooling circuits—ensuring safe, efficient, and long-lasting battery operation under dynamic load conditions.
As part of NEWBASE's integrated thermal management portfolio, the high-voltage PT sensor complies with stringent automotive safety and electromagnetic compatibility standards, making it an essential element in functional safety architectures defined by ISO 26262 (ASIL B/C) and UN ECE R100.
Key Features & Technical Advantages
Precision Platinum RTD Sensing Element
The sensor utilizes a Pt1000 or Pt100 platinum resistance element (IEC 60751 Class A or B accuracy), offering excellent linearity, repeatability, and long-term stability over a wide temperature range. With a typical accuracy of ± 0.3°C at 0-100°C, it enables fine-grained thermal control algorithms that prevent overheating, thermal runaway, and uneven cell aging.
According to SAE J2929 and IEC 62660-2 guidelines for lithium-ion battery safety, accurate temperature feedback from multiple points is mandatory for effective battery management—making high-precision PT sensors indispensable.
High-Voltage Isolation & Electrical Safety
Designed explicitly for high-voltage traction battery systems, the PT sensor features:
  • Reinforced insulation between the sensing element and signal leads
  • Dielectric strength ≥ 4 kV AC (1 min)
  • Creepage and clearance distances compliant with IEC 60664-1 for 1,500 VDC systems
This ensures operator and system safety even during fault conditions, meeting requirements of ISO 6469-3 and UL 2580 for electric vehicle battery safety.
Robust Mechanical & Environmental Design
Housed in a stainless steel (AISI 316L) or PEEK sheath, the sensor resists:
  • Coolant exposure (ethylene/propylene glycol mixtures)
  • Vibration and mechanical shock (SAE J2380 validated)
  • Corrosive atmospheres and road salts
The probe tip is often laser-welded and hermetically sealed, achieving an IP67 or IP6K9K rating per IEC 60529, allowing direct immersion in liquid-cooled plates or attachment to high-voltage terminals without risk of moisture ingress.
Optimized for KD (Knock-Down) Integration
As a KD kit component, the PT sensor is supplied with:
  • Pre-molded high-voltage connectors (e.g., TE Connectivity AMP+, Yazaki, or Delphi Packard)
  • Defined lead lengths and routing paths for automated assembly
  • Color-coded or labeled variants for multi-zone battery packs
This streamlines final assembly at regional manufacturing sites while ensuring consistent performance and traceability—critical for global OEM supply chains.
Low EMI Emission & Signal Integrity
The sensor employs twisted-pair shielded cabling with foil + braid shielding, minimizing electromagnetic interference in noisy high-power environments. This design complies with CISPR 25 Class 3 and supports reliable communication with the Battery Management System (BMS) even alongside inverters and DC-DC converters.

Applications
  • Liquid-cooled battery packs for electric buses (including 24kW heat pump-integrated platforms)
  • Battery module interconnect monitoring
  • Cold plate surface temperature sensing
  • HV junction box and fuse temperature supervision
  • Thermal runaway early-warning systems
In systems using indirect cooling (e.g., refrigerant-to-coolant via plate heat exchanger), these sensors provide the critical feedback loop needed for coordinated control between the BMS and HVAC controller—enabling strategies like active battery preconditioning during charging.
Industry Context & Compliance
As noted by the International Council on Clean Transportation (ICCT) and Argonne National Laboratory, precise temperature control is among the top three factors influencing battery cycle life and fast-charging capability. The use of high-voltage-rated PT sensors—rather than NTC thermistors—is increasingly favored in commercial EVs due to their superior accuracy, drift resistance, and standardization across global platforms.
NEWBASE's high-voltage PT sensor aligns with this trend, offering a safety-certified, production-ready solution that supports the scalability and reliability demands of next-generation electric mobility.
For integration into your KD battery pack assembly, NEWBASE provides full engineering support—including DFMEA documentation, thermal simulation validation, and connector customization—to ensure seamless compatibility with your BMS architecture and manufacturing process.
