The invention relates to the field of battery balancing, and provides a new energy automobile battery pack load balancing scheduling method and system, and the method comprises the steps: obtaining the voltage difference data of each single battery in a battery pack, calculating the electrode deviation degree of the single batteries according to the voltage difference data, screening out the abnormal single batteries in the battery pack according to the electrode deviation degree, and carrying out the load balancing scheduling of the battery pack. And carrying out voltage regulation on the abnormal single battery to complete load balancing. According to the method, accurate and efficient battery load balancing can be realized, the service life of the new energy battery pack is greatly prolonged, the charging and discharging energy efficiency is greatly improved, performance reduction of the battery pack caused by voltage imbalance of the battery monomers is avoided, the battery monomers with abnormal loads are accurately identified by using the electrode deviation degree and are processed in time, and the reliability of the battery pack is improved. Load scheduling of each single battery is efficiently completed, and meanwhile, the stability of the battery pack in the charging and discharging process is ensured, so that the new energy automobile can keep excellent battery performance under various working conditions.
