The invention discloses an automatic charging system and method for a low-voltage battery of an electric vehicle, and the system comprises a power battery module, a DC power supply conversion module, a low-voltage power storage module, a vehicle control module and a Tbox module, and the method comprises the steps: 1, charging judgment; 2, vehicle condition judgment; step 3, starting charging; 4, real-time monitoring is carried out; 5, charging is completed; compared with an existing automatic charging system for the low-voltage battery, the designed vehicle control module and the Tbox module can automatically charge the low-voltage battery, a discharging loop of the low-voltage battery does not need to be cut off, and it is ensured that the battery is not lack of electricity or over-discharged or over-charged; according to the invention, the external power supply module and the input switching module provide multiple power supply modes, so that the service life of a power battery is prevented from being shortened due to a single path; through a mode of allowing a user to operate by himself/herself, the charging of the low-voltage battery is not limited to the hard requirement of voltage, and the charging operation can be flexibly carried out.
本发明公开了一种电动汽车低压电池自动补电系统及方法,包括动力电池模块、直流电源转换模块、低压蓄电模块、整车控制模块、Tbox模块,方法包括步骤一,充电判断;步骤二,车辆情况判断;步骤三,开始充电;步骤四,实时监测;步骤五,充电完成;本发明相较于现有的低压电池自动补电系统,设计的整车控制模块、Tbox模块可以自动为低压电池进行补电,无需切断低压电池的放电回路,且确保了电池不会亏电、过放或过充;本发明设计的外部电源模块、输入切换模块提供了多种供电方式,避免单一途径造成动力电池寿命下降;本发明通过允许用户自行操作的方式,使低压电池的补电不限于电压的硬性需求,能够灵活的进行补电操作。
