Battery Management System BMS
The battery management system (BATTERY MANAGEMENT SYSTEM) is the link between the battery and the user, and the main object is the secondary battery. The secondary battery has the following disadvantages such as low storage energy, short life, serial and parallel use problems, safety of use, difficulty in estimating battery power, and the like. The performance of the battery is very complicated, and the characteristics of different types of batteries vary greatly. The battery management system (BMS) is mainly to improve the utilization of the battery, prevent overcharging and overdischarging of the battery, prolong the service life of the battery, and monitor the state of the battery. As battery management systems evolve, additional features will be added. Generally speaking, the electric vehicle battery management system must realize the following functions: Firstly, accurately estimate the state of charge of the power battery pack, that is, the remaining battery power, and ensure that the SOC is maintained within a reasonable range to prevent overcharge or overdischarge. The damage of the battery, so as to predict at any time how much energy is left in the energy storage battery of the hybrid vehicle or the state of charge of the energy storage battery. Secondly, the working state of the power battery pack is dynamically monitored. During the charging and discharging process of the battery, the terminal voltage and temperature, the charging and discharging current and the total voltage of the battery pack of each battery in the battery pack of the electric vehicle are collected in real time to prevent overcharging or overdischarging of the battery. At the same time, the battery condition can be given in time, and the problematic battery can be selected to maintain the reliability and high efficiency of the entire battery operation, and the realization of the remaining battery estimation model becomes possible. In addition, it is necessary to establish a usage history file for each battery to provide data for further optimization and development of new types of electricity, chargers, motors, etc., and to provide a basis for offline analysis system failure. Finally, the balance between the cells is achieved, that is, the cells are uniformly charged, so that the cells in the battery pack reach a state of equilibrium. Equilibrium technology is the key technology of a battery energy management system that the world is currently researching and developing. For instance, the seat should heat from 30-degrees C to 60-degrees C with three to five heating options. With such a unit, you can choose the perfect heating temperature that will suit every situation.
