Abstract

The invention provides a vehicle-mounted battery managing system applied to the technical field of electric bicycle vehicle-mounted battery managing. The vehicle-mounted battery managing system comprises a voltage collecting unit for collecting the voltage values of a battery cell, a current collecting unit for collecting the current values of charging and discharging, a temperature collecting unit for collecting the temperature values of the battery cell, a data storage unit for storing original data, a data processing unit for processing the original data to obtain secondary data, a CAN communication unit for sending the secondary data to a vehicle control unit, and a WIFI communication unit for searching for WIFI access points in real time and sending the original data to the WIFI access points. The vehicle-mounted battery managing system can effectively solve the problem that various state information of a vehicle-mounted storage battery is lost when the network breaks down. The vehicle-mounted battery managing system has the advantages of being high in data transmission speed and quality, low in cost and the like.

Description

technical field [0001] The present invention relates to the technical field of battery management, in particular to a vehicle battery management system. Background technique [0002] The on-board BMS (Battery Management System, battery management system) is used to manage and maintain the on-board battery pack of the electric vehicle to make it work stably. The battery pack on an electric vehicle usually consists of many single cells connected in series to work. After the battery pack is put into use, the actual capacity of each single cell always develops from a balanced state to an unbalanced state. The on-board BMS An important task is to balance all single cells. [0003] The on-board BMS is used to monitor the voltage, current, and temperature of the single battery at all times, perform leakage detection, thermal management, battery balance management, alarm reminder, calculate remaining capacity and discharge power, and report SOH (State of Health, battery health stat...
