Embodiment Construction

[0029] The vehicle battery aging control system and vehicles proposed by the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description. It should be noted that all the drawings are in a very simplified form and use imprecise scales, and are only used to facilitate and clearly assist the purpose of illustrating the embodiments of the present invention.

[0030] As mentioned in the background art, since the vehicle battery is in a non-saturated and undercharged state for a long period of time during use, the aging speed of the battery will be accelerated. Due to the high cost of replacing the battery, this will bring about an increase in economic and time costs to the consumer. The vehicle battery aging control system of the embodiment of the present application is proposed to obtain the aging state of ...

Abstract

The invention provides a vehicle storage battery aging control system and a vehicle comprising the same. According to the aging control system for the vehicle storage battery, a battery aging model isused for calculating aging values of the related vehicle storage battery in different charge states, and whether the vehicle storage battery needs to be charged or not is judged according to the aging values, wherein when the aging value is greater than a first aging protection threshold, an instruction of executing full-load charging on the vehicle storage battery once is output, so that full-load charging can be carried out in time as required before the permanent battery performance is reduced due to long-time unsaturated state work of the battery, the aging speed of the vehicle storage battery can be reduced, and the service life can be prolonged.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a vehicle battery aging control system and a vehicle. Background technique [0002] Storage batteries such as lead-acid batteries, nickel-metal hydride batteries, and lithium-ion batteries have been widely used in various vehicles. Taking electric vehicles as an example, in addition to the power battery that provides power for high-voltage drive components, it usually includes an auxiliary battery that provides power for the vehicle's voltage electrical appliances and control systems. Since the lead-acid battery has the advantages of cheap price, abundant material sources, high specific power, relatively mature technology and manufacturing process, and high resource recovery rate, the auxiliary battery usually uses a 12V lead-acid battery, which can be used for various electrical loads such as engines. , instrumentation, lighting, air conditioning and other auxiliary electrica...
