First, the role of the battery rectifier module Battery rectifier module is a kind of electrical equipment, mainly used for current control, can realize the battery charging and discharging control. Its main role is as follows: 1. control the battery charging process: the battery rectifier module can control the size and direction of the current, you can realize the proper charging of the battery to maintain the normal use of the battery. 2. control the battery discharge process: the …

I. Working principle of lithium-ion battery Lithium-ion batteries are high-performance batteries that are widely used in mobile electronic devices, power tools, automobiles and other fields. The lithium-ion battery module consists of multiple single cells, each of which has a positive and negative electrode and electrolyte. When the battery is discharged, lithium ions at the positive electrode move toward the negative electrode and electrons flow through the external circuit, completi…

The battery in a diesel generator set is an important part of its starting system, which is responsible for providing the necessary power for the starter motor to ensure the smooth start of the generator set. However, in actual use, the battery may encounter a variety of failures, affecting the normal start of the generator set. Here are some common reasons that may lead to diesel generator set battery failure: First, excessive discharge Over-discharge of the battery is one of the mai…

Battery pack is an important component of electric vehicles, which not only provides power to the vehicle but also serves as an energy storage device. The analysis of conventional electrical principles and schemes of battery packs is important for understanding the operation and design optimization of electric vehicles. In the following, we will analyze the conventional electrical principles and schemes of battery packs from the following aspects: First, the basic composition of the b…

First, the battery monitoring module can not charge The inability to charge the electric car may be caused by the failure of the battery monitoring module. The main role of the battery monitoring module is to monitor the battery status, when the charging current or charging voltage is too high, the battery monitoring module will automatically stop charging to protect the battery. If the battery monitoring module fails, the battery will not be charged. The solution is to check whether …

In the Mercedes-Benz W221 dual battery system, for example, the task of the power control system is to provide power to all electrical equipment and components of the vehicle as required. In order to maintain reliability, the power control system provides two power lines, one for the starter battery line and the other for the main battery line. The vehicle power supply control unit (N82/1) regulates the two battery lines to different parameters and characteristics. To ensure proper ve…
