3. Cold-Start Circuit To ensure the effective operation of the power management unit (PMU), a cold-start circuit is required in the energy harvesting system to generate an initial clock signal at ultra-low input voltages. As shown in Figure 9, the designed energy harvesting system collects and converts external energy into electrical energy.
In low-power scenarios, such as microwaves, sound, friction, and pressure, a specific low-power energy harvesting system is required. Due to the absence of an external power supply in such systems, cold-start circuits play a crucial role in igniting the low-power energy harvesting system, ensuring a reliable start-up from the initial state.
An optimized cold-start circuit should exhibit high conversion efficiency to minimize wasted power, thereby extending battery life and reducing energy costs. Furthermore, the dynamic range of the cold-start circuit needs to be sufficiently wide to account for inevitable variations in voltage and power.
Furthermore, the dynamic range of the cold-start circuit needs to be sufficiently wide to account for inevitable variations in voltage and power. The most critical aspect is the anti-interference capability, which is used as the key parameter for evaluating the stability and reliability of the cold-start procedure.
Additionally, the systems must exhibit unaided cold-start capability at −30 °C and assisted cold-start functionality at −40 °C, with the total energy consumption during cold start and shutdown not exceeding 5 MJ . Table 1 presents typical fuel cell vehicle models and their cold-start parameters.
Integrated thermal management model derived the optimal strategy under cold-start. When an energy storage system (ESS) operates in cold conditions, the power and capacity of the battery critically fade. Therefore, an appropriate battery thermal management strategy (BTMS) is essential to prevent severe driving range loss at low ambient temperatures.
