Embodiment 1
[0048] figure 1 It is a flow chart of a power management method containing multiple energy storage devices according to an exemplary embodiment. The method is used in a vehicle, and the method includes the following steps:
[0049] Step 101 , when the task message is received, obtain vehicle operation-related data, power battery-related data, and battery voltage, respectively.
[0050] The above-mentioned data related to vehicle operation at least include: key door information, vehicle gear position information, vehicle speed, braking, accelerator, entertainment information, air conditioning information and vehicle controller instructions. The data related to the power battery at least include: charge amount information, total power battery voltage, power battery temperature, power battery cell voltage, and power battery total current.
[0051] Step 102: Determine an operating state according to the vehicle operation-related data and power battery-related data, and execute a ...
Embodiment 2
[0071] Figure 5 It is a structural diagram of a power management device containing multiple energy storage devices according to an exemplary embodiment, including:
[0072] a data acquisition module 210, configured to acquire vehicle operation-related data, power battery-related data and battery voltage respectively when a task message is received;
[0073] An execution strategy module 220 is configured to determine an operating state according to the vehicle operation-related data and power battery-related data, and execute a corresponding control strategy according to the operating state.
[0074] In this patent, the controller and the sampling chip enter different modes in different operating modes of the vehicle to avoid over-discharge of the power battery and the battery, and at the same time, the controller and the sampling chip are periodically woken up to monitor the state of the power battery.
Embodiment 3
[0076] Image 6 It is a structural block diagram of a vehicle provided by an embodiment of the present application, and the vehicle may be the vehicle in the above-mentioned embodiment. The vehicle 300 may be a portable mobile vehicle, such as a smartphone, a tablet computer. Vehicle 300 may also be referred to by other names such as user equipment, portable vehicle, or the like.
[0077] Generally, the vehicle 300 includes a processor 301 and a memory 302 .
[0078] The processor 301 may include one or more processing cores, such as a 4-core processor, an 8-core processor, and the like. The processor 301 may adopt at least one hardware form of DSP (Digital Signal Processing, digital signal processing), FPGA (Field-Programmable Gate Array, field programmable gate array), PLA (Programmable Logic Array, programmable logic array) accomplish.
