New Energy Power parts Cooling system controller assembly 3613520-TE810

As the "command center" of the NEV’s cooling system, the 3613520-TE810 assembly delivers real-time, precision control of multi-component thermal balance to optimize the performance, safety, and lifespan of critical NEV parts. It collects data from 20+ sensors (temperature, pressure, flow rate) across the vehicle at a 1.2kHz sampling rate—monitoring battery cell temperatures, motor/inverter heat levels, coolant loop pressure, and ambient temperature. The embedded software executes three key intelligent strategies: 1) Battery Thermal Optimization: Adjusts BTMS water pump speed and EEV opening to keep battery cells within 20-45°C (ideal for charging speed and cycle life), including pre-heating in cold weather (≤5°C) using powertrain waste heat; 2) Powertrain Overheat Prevention: Modulates powertrain cooling loop flow and radiator fan speed to limit motor/inverter temperatures to ≤115°C during high-load operation (e.g., rapid acceleration, uphill driving); 3) Fuel Cell Temperature Stabilization (for FCVs): Maintains fuel cell stack temperature at 65-75°C via adaptive coolant flow, ensuring efficient hydrogen-electrolyte reaction and avoiding stack damage. This cross-component coordination reduces overall energy consumption by 18-25% compared to independent cooling control

The 3613520-TE810 cooling system controller features a NEV-optimized rugged structure built to withstand the unique challenges of NEV operation—including high-voltage electromagnetic interference (EMI), extreme temperature fluctuations, and under-vehicle moisture/dust. The outer housing is constructed from die-cast aluminum alloy (ADC12) with a corrosion-resistant zinc-nickel plating, providing impact resistance (up to 30G peak acceleration, compliant with ISO 16750-3) to handle road debris and vibration during long-haul trips. The internal circuit board uses a triple-layer conformal coating (epoxy + acrylic + silicone) to shield components from moisture, dust, and chemical corrosion (e.g., coolant splashes, road salt). Critical hardware components—including a dual-core automotive MCU (NXP S32G49, 600+ MIPS processing power), high-voltage isolated CAN FD transceivers, and power driver ICs—are rated for an operating temperature range of -40°C to 130°C, ensuring stable performance in freezing winters or hot under-hood environments. The controller also has an IP6K9K waterproof/dustproof rating and meets EMC standards (CISPR 25 Class 5) to resist EMI from NEV high-voltage batteries and motors, preventing signal interference

The 3613520-TE810 is calibrated with NEV-specific technical parameters to maximize cooling efficiency and energy savings. Its processing capacity (600+ MIPS) enables simultaneous control of 10+ cooling peripherals (water pumps, fans, EEVs) with sub-10ms response time—critical for mitigating sudden temperature spikes (e.g., during fast charging). The electrical system supports NEV common voltages: 12V/24V for low-voltage control circuits and includes 4kV high-voltage isolation to protect against electrical surges from the vehicle’s 300V-800V high-voltage battery. For communication, it uses dual redundant CAN FD channels (up to 8Mbps) to exchange real-time data with the vehicle’s VCU (Vehicle Control Unit) and cooling subsystems, ensuring data reliability even in noisy electrical environments. The controller also features ultra-low standby power consumption (≤2.2W) to avoid battery drain when the vehicle is off, and its non-volatile memory can store 200+ thermal management event logs for 8+ years—facilitating post-fault analysis and predictive maintenance

Both the hardware and software of the 3613520-TE810 cooling system controller meet strict global NEV quality and safety standards. The hardware is manufactured in accordance with ISO/TS 16949, with 100% factory testing including: electrical performance validation (signal accuracy, voltage stability, high-voltage isolation), environmental stress testing (temperature cycling, humidity, vibration), and durability testing (simulating 15-year/350,000km NEV lifespan). The software is certified to ISO 26262 (functional safety) at ASIL B level—essential for protecting safety-critical components like high-voltage batteries and fuel cell stacks. It also complies with NEV-specific standards: GB/T 18384 (EV safety requirements) for Chinese-market models, IEC 60664 (high-voltage insulation coordination) for high-voltage compatibility, and ISO 14644-1 Class 8 (cleanroom standards) for FCV-compatible units (to prevent coolant contamination of fuel cell stacks). To support NEV manufacturers and repair facilities, the controller comes with a 36-month/100,000km warranty (covering hardware defects and software bugs) and dedicated technical support—including thermal strategy calibration, CAN FD protocol configuration, and fault diagnosis training
