Intelligent charger with diagnostic function and charging method

Abstract

The invention discloses an intelligent charger with a diagnostic function and a charging method, and belongs to the intelligent charger and the charging method. The intelligent charger comprises a control module, a diagnosis module, a charge module, a multi-path switch and a detection module, wherein the control module is sequentially connected with the diagnosis module, the charge module and the multi-path switch; and the detection module is sequentially connected with an external connection terminal of a battery, the multi-path switch and the fault diagnosis module. The charging method comprises two modes: a charge mode and a diagnosis mode; the diagnosis mode comprises two parts of functions, namely fault diagnosis and lifetime detection; the fault diagnosis is detecting a fault problem which can be generated by the battery to provide a hint; and the lifetime detection is detecting the capacity of the current battery, and determining the lifetime of the current battery through the ratio of current capacity to rated capacity. The intelligent charger has the advantages that the intelligent charger has the charge function and the diagnosis function, can measure the lifetime and the fault type of the battery; the charge remaining time of the battery at night is fully utilized; a plurality of selection modes are included; and monitoring of the lifetime and the health state of the battery is achieved.

Description

technical field [0001] The invention relates to an intelligent charger and a charging method, in particular to an intelligent charger with a diagnosis function and a charging method. Background technique [0002] As the power source of electric vehicles, the power battery will inevitably experience various failures or aging due to the complex working environment and changing operating conditions. Failure to detect or deal with a fault in time may lead to a safety accident. [0003] There are related patents on battery fault diagnosis and battery charger. Yet these patents all exist some deficiencies. When electric vehicles are charged at night, there is still a lot of time available after being fully charged, which is just ignored by ordinary chargers. For the user, it is cumbersome and troublesome to purchase a battery fault diagnosis device and keep using it, and it is inconvenient to use. Contents of the invention [0004] The object of the present invention is to p...
