Abstract

The invention discloses a method and a device for assessing service conditions of batteries. The device for assessing the service conditions of the batteries comprises a mode recognizing unit and a service condition assessing unit. The mode recognizing unit is configured in such a manner that service modes of the batteries in a certain time period and attenuation curves corresponding to the service modes can be recognized according to recorded data relevant to service of the batteries, stored service modes of the batteries and stored attenuation curves corresponding to the various service modes, and the attenuation curves represent variation of the full-charge capacity of the batteries along with the service of the batteries; the service condition assessing unit is configured in such a manner that degradation of the batteries can be computed according to the recorded data, the recognized service modes and the attenuation curves corresponding to the recognized service modes, and degradation of the batteries represents decrease of the full-charge capacity of the batteries along with increase of the service of the batteries. The method and the device have the advantages that the service conditions of the batteries can be accurately assessed, and accordingly residual service value of the batteries during operation can be reasonably judged.

Description

technical field [0001] The present invention relates to a method and device for evaluating the usage status of a battery, a related system and a vehicle, and more particularly, to a method for evaluating the usage status of a battery using recorded data related to battery usage and a pre-established pattern table and devices, related systems and vehicles. Background technique [0002] As the auto industry booms, electric car batteries are slow and expensive to charge. At present, there are mainly two battery operation modes for electric vehicles. [0003] One is the charging mode, that is, users still purchase batteries when purchasing electric vehicles, and charge them at charging stations or charging piles provided by operators. In the charging mode, the user can choose slow charging or fast charging according to the situation. The former has a low rate for a long time, and the latter has a high rate for a short time. Both types of charging facilities are operated by o...
