Functions and functions of 1.5v dry cell battery equalization management system
The functional role of the 1.5v dry cell battery balance management system. The 1.5v dry cell battery balance management system can effectively monitor, protect, energy balance and fault alarm the lithium battery pack, thereby improving the working efficiency and service life of the entire power battery pack. Therefore, it is necessary to equip the lithium battery pack with a targeted lithium battery management system BMS, which is the primary task of the lithium power battery management system.
Functions and functions of 1.5v dry cell battery equalization management system
Differences in the manufacturing and use processes have resulted in natural inconsistencies in power battery cells. The inconsistency of the battery cells will further deteriorate over time under the influence of random factors such as temperature and vibration conditions, causing the parameters to move in the direction of discretization and go away without hesitation. One of the methods is to balance the cells through the 1.5v dry cell battery balancing management system.
As a powerful guarantee for the safe use of batteries, the lithium battery pack balancing BMS management system enables the battery to be in a safe and controllable charging and discharging process at all times, greatly improving the cycle life of the battery in actual use. The three core functions of the 1.5v dry cell battery management system are cell monitoring, state-of-charge estimation and single cell balancing.
1) Battery core monitoring technology
Single cell voltage collection; single cell temperature collection; lithium battery pack current detection;
Accurate temperature measurement is also very important for the working status of the lithium battery pack, including temperature measurement of individual cells and temperature monitoring of the battery pack’s heat dissipation liquid. This requires reasonably setting the location and number of temperature sensors to form a good cooperation with the BMS control module. The monitoring of the heat dissipation liquid temperature of the lithium battery pack focuses on the fluid temperature at the inlet and outlet. The selection of monitoring accuracy is similar to that of single cells.
2) SOC technology: Simply put, it is how much power is left in the battery
SOC is the most important parameter in the BMS lithium battery pack management system. Because everything else is based on SOC, its accuracy and robustness (also called error correction capability) are extremely important. Without accurate SOC, no amount of protection functions can make the BMS work properly, because the battery will always be in a protected state, and the life of the battery cannot be extended.
3) Balance technology
Passive equalization generally uses resistance to release heat to release the "excess power" of high-capacity batteries to achieve the purpose of balancing. The circuit is simple and reliable, and the cost is low, but the battery efficiency is also low.
The lithium battery management system is not dispensable as some battery manufacturers say, but a must, and it must be present throughout the battery pack application. There have been many studies on the BMS lithium battery management system at home and abroad, and it has begun to be applied in many fields. It has been able to meet the needs of some markets. The application of lithium power batteries has put forward higher requirements for the battery management system to ensure the safety of the power lithium battery pack. Safe to use.
Which equalization technology should BMS use better?
Generally speaking, passive balancing is suitable for lithium battery pack applications with small capacity and low string count, while active balancing is suitable for power lithium battery pack applications with high string count and large capacity. Rather than which balancing technique is better, it is more important to say the strategy behind it. However, passive equalization also has significant shortcomings. Due to its simple structure and low production cost, it uses resistors to consume energy and generate heat, which will reduce the efficiency of the entire system. Active balancing adopts the principle of energy transfer and distribution, so the energy utilization rate is higher than passive balancing.
BMS lithium battery pack passive balancing technology has been applied in the electric market before active balancing, and the technology is relatively mature. The passive balancing structure is simpler and is widely used; while the active balancing is more complex, and the design of the transformer scheme and the switch matrix will undoubtedly increase the cost significantly.
Summary: The battery management system BMS manages and protects the operation of the lithium battery pack. The BMS collects important information during the operation of the battery pack in real time, protects the safe operation of the battery pack, and interacts with external devices such as vehicle controllers and grid energy storage hosts in real time. information to protect the safe operation of the battery pack and provide important data for efficient and energy-saving operation of the system.
