Embodiment Construction

[0050] If the DCDC can complete the charging of the 12V battery by itself, the first thing to solve is the detection and judgment of the battery voltage, the second is the charging of the 12V battery after the DCDC is actively awakened, and the last is the complete vehicle after the power supply is interrupted and the charging is completed. Retime problem.

[0051] This technology can also be developed as an optional function by developing remote control to realize intelligent power supply operation.

[0052] (1) Detection and judgment conditions of 12V battery voltage

[0053] The smart power replenishment function is "select" to enable the function, and the setting operation can be completed on the HU screen (it can also be realized remotely through the mobile phone).

[0054] First of all, the driver can select this function to be on by operating the intelligent power supply function switch. At this time, the smart power supply function will be successfully activated, and...

Abstract

The invention relates to an electric automobile storage battery charging method, in particular to an intelligent charging method for an automobile starting power source. The intelligent charging method comprises the following steps: (1) detecting and judging the voltage of a 12V storage battery; (2) charging the 12V storage battery by the DCDC; and (3) reminding and re-timing after intelligent charging is finished. Compared with the prior art, the method has the beneficial effects that (1) the requirement of the static days of the whole vehicle on the capacity of the storage battery is reduced, the capacity of the storage battery can be reduced, and the method plays a positive role in the cost and weight target of the whole vehicle; (2) the voltage value is used as an intelligent charging judgment condition, so that the development work of the storage battery sensor is reduced, the development period is shortened, and the development cost is reduced; and (3) when the quiescent current is too large due to the fault of the whole vehicle, the power shortage risk of the 12V storage battery is reduced, and the influence of the use of the vehicle by customers is reduced.

Description

technical field [0001] The invention relates to a battery charging method of an electric vehicle, in particular to an intelligent charging method for starting a power supply of the vehicle. Background technique [0002] At present, new energy vehicles, especially electric vehicles, have a good momentum of development. An electric vehicle refers to a vehicle powered by a vehicle-mounted power supply and driven by a motor to drive the wheels. The principle is based on the output current of the battery, which adjusts the load power through a power regulator, and drives the motor to drive the vehicle through the power transmission system. The applicant expounds the current status of the electric vehicle industry from three aspects, thereby deriving the necessity and inevitable trend of intelligent supplementary power for the vehicle's on-board starter power supply. [0003] First, the functions of the on-board 12V battery include the following aspects: [0004] 1. When the veh...
