The embodiments of the invention provide a storage battery charging control method, a vehicle control unit, a system and a vehicle. The control method comprises the steps that the service life of a storage battery and the residual electric quantity of the storage battery which are detected by a storage battery sensor are obtained; a charging starting threshold value corresponding to the service life of the storage battery is obtained according to the service life of the storage battery; the residual electric quantity of the storage battery is compared with a charging starting threshold value;and when the comparison result is that the residual electric quantity of the storage battery is smaller than the charging starting threshold value, the whole vehicle high-voltage system is controlledto be powered on, and a first control signal is sent to a direct-current converter. In the embodiments of the invention, the vehicle control unit can acquire the storage battery life detected by the storage battery sensor and the residual electric quantity of the storage battery in real time, obtains the charging starting threshold value corresponding to the storage battery life, and charges the storage battery when determining that the residual electric quantity of the storage battery is smaller than the charging starting threshold value; the storage battery is ensured to be in a high electric quantity state, and the service life of the storage battery is ensured.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a control method for battery charging, a vehicle controller, a system and a vehicle. Background technique [0002] The battery intelligent charging control method of existing products adopts a fixed start-stop threshold, does not consider the aging state of the battery, and cannot be adjusted in real time according to the aging state of the battery, and must adopt an intermediate value compatible with old and new batteries. The middle value may be too low for a new battery, and the new battery must be discharged to a lower value before it can enter smart charging, which accelerates the aging of the battery to a certain extent; the middle value may be too high for an old battery, and at the end of the life of the battery, it cannot be charged at all to the end threshold of intelligent charging, resulting in waste of electric energy.
