Example Embodiment

[0031] Embodiment: A car battery monitoring system of this embodiment, such as figure 1 As shown, it includes a controller 1, a current and voltage detection module 2, an in-position detector 3, a parking brake detector 4, a liquid level sensor 5, a density sensor 6, a level sensor 7, a distilled water valve 8 and an electrolyte valve 9. The controllers are respectively connected to the position detector, the current and voltage detection module, the parking brake detector, the liquid level sensor, the density sensor, the level sensor, the distilled water valve, the electrolyte valve, the engine controller 11 and the central control lock 12. The current and voltage detection module is connected to the positive electrode and the negative electrode of the battery 10. Both the distilled water valve and the electrolyte valve are electronically controlled valves. The liquid level sensor and density sensor are installed inside the battery, the parking brake detector is connected to t...

Abstract

The invention discloses a vehicle accumulator monitoring method and a system. The method comprises the steps of: (A) entering a step B if a remote control locking signal is not received within 20 seconds after an engine is stopped; and entering a step C if the remote control locking signal is received; (B) detecting the self-discharge current of an accumulator in 10 seconds of receiving the remote control locking signal; and warning in a wireless manner if the self-discharge current is greater than a current threshold; (C) detecting the voltage of the accumulator; entering a step D if the voltage of the accumulator is lower than a lower limit of the voltage; and finishing the flow if the voltage of the accumulator is higher than or equal to the lower limit of the voltage; and (D) detecting if a driver is in a vehicle by an in-place detector, blinking to warn through an electricity-deficient warning lamp if the driver is in the vehicle, and warning in a wireless manner if the driver is not in the vehicle. The method prompts the driver to timely treat faults to prevent the incapability of vehicle starting caused by high-current self-discharge for a long time. The method is suitable for all vehicle accumulators.

Description

technical field [0001] The invention relates to the field of automobile battery management, in particular to an automobile battery monitoring method and system. Background technique [0002] Existing vehicles lack monitoring of battery power, and there is only a generator status prompt, which cannot identify whether the battery is charged, cannot identify the storage capacity of the battery, and cannot identify whether the battery is self-discharging. If the battery cannot be charged and used for a long time, it will eventually cause the vehicle to fail to start and cause a breakdown accident. [0003] The State Intellectual Property Office of the People's Republic of China published a patent document with the publication number CN102381209A on March 21, 2012. The name is a low-voltage battery fault management method for pure electric vehicles, which is specifically: in any of the following four fault conditions When this happens, the vehicle controller thinks that the batt...
