Description:

The fuel cell controller (FCCU) is the central control unit of a fuel cell engine system, known as the "brain" of the system. It is responsible for collecting sensor signals of the whole system, driving the actions of each actuator, and coordinating the air circuit, hydrogen circuit, thermal management and electronic control systems, ensuring safe, efficient and stable operation of the fuel cell system.

The J01-01 fuel cell controller is a fuel cell stack controller developed specifically for 0~150kW system requirements.

Hardware platform: the main control chip uses a 32-bit Arm Cortex-M7 dual-core processor (S32K324NHT1MPBST), with a main frequency of up to 160MHz and 4MB Program Flash and 320KB RAM. The chip has abundant resources: 72 channels of 12-bit ADC can meet the needs of large-scale sensor signal acquisition, and the built-in 3 CAN interfaces support CANFD (baud rate 6.6Mbps, backward compatible with CAN); the 2 M7 cores can meet the ISO 26262 ASIL B functional safety requirements.

Abundant drive resources:

• PeakHold drive: 6 channels (continuous 3A, peak 7A), designed specifically for inductive loads such as hydrogen injection valves, sharing one high-side group; it is recommended to stagger by more than 500us
• H-bridge drive: 4 channels, 5A continuous per channel, 7A peak, with fault diagnosis
• Low-side PWM drive: 4 channels, 2A per channel, frequency 0~10kHz
• Low-side switch drive: 13 channels (4 channels 3A + 9 channels 1A)
• High-side PWM drive: 3 channels, 2A per channel
• High-side power supply output: 2 channels 10A (1 channel for the hydrogen injection load, 1 channel for other low-side loads)

Comprehensive sensor interfaces:

• Analog input: 32 channels (14 voltage type + 17 resistance type + 1 current type 4~20mA)
• Switch input: 3 channels (active high)
• Frequency input: 6 channels (0~12kHz, able to acquire frequency and duty cycle)
• SENT signal: 3 channels
• Hard-wire wake-up: 1 channel (ON switch, valid above 6V)
• 5V external sensor supply: 3 independent outputs (250mA each, with short-circuit protection)
• 12V external sensor supply: 1 channel (max 2A)

Vehicle-grade reliability: working temperature range -40C~+85C, protection class IP67 (when the connector is properly connected, measured up to IP68 @ 1m water depth for 24 hours). Total average current <15A, static leakage current <1.6mA@24V. Altitude adaptability <=5000m, using natural cooling.

Multiple protection functions: the controller has built-in multiple safety mechanisms such as PeakHold high-side/low-side over-current protection, H-bridge drive protection, low-side PWM drive protection, high-side PWM drive protection and high-side power supply output protection. The protection thresholds are calculated theoretically based on an ambient temperature of 25C, ensuring safe shutdown of the system under abnormal working conditions.
