The on-board energy system is one of the three core technologies of electric vehicles. It is like the engine of a traditional internal-combustion engine, and it is the “heart†of electric vehicles and the only source of power for electric vehicles. It accounts for 1/3 of the total cost of electric vehicles. The technical level of the on-board energy system is directly related to the quality level and safety of electric vehicles. The energy management system (BMS) is an important part of this core technology. As the vehicle power system is a huge battery pack, which is composed of dozens or even hundreds of single cells, the consistency and balance of the battery are crucial. It is related to the life and safety of the battery. The function of the energy management system is to monitor the status of each battery and the battery level, health, and high-voltage leakage detection to ensure the balance of these hundreds of batteries. Its importance is obvious. In recent years, lithium-ion batteries have become the mainstream choice for power batteries because of their superior performance. The investment in lithium-ion batteries at home and abroad is also very large. The characteristics of lithium batteries make the role of the battery management system even more important.
The number of charge and discharge cycles of a conventional lead-acid battery single 2V battery can reach 1,000 times. However, when the single battery is composed of a 36V or 48V battery pack, the overall number of cycles is reduced to about 400 times. If the voltage increases, the overall number of cycles decreases again.
O2Micro's aerobic lead-acid battery technology implants power management chips in traditional lead-acid battery modules. By using power management and equalization, the number of charge/discharge cycles of the battery pack is the same as that of the single cells, which can effectively extend the tradition. The service life of lead-acid batteries is 1-2 times, and their recoverability is greatly improved. According to a conservative estimate, based on the current total of 130 million EVs in China, the application of aerobic lead-acid battery technology will save China about 1.2 megatons of lead. If a lead with a cross-sectional diameter of 5 centimeters is to be produced, It can be a week around the earth; it can save 57 trillion Chinese, equivalent to a population of 350,000 people in Weihai City, a year of household electricity consumption. The advent of this technology will greatly reduce the cost of use of consumers. For dealers and manufacturers, it will also reduce the rate of battery repair and return rate, while reducing the use and emissions of lead, to protect the environment, build a green transport system with Significance.

Laser head structure
1.The Z axis refers to the direction in which the laser head moves up and down
2.Structural composition: 1. Servo motor; 2. Guide rail slider; 3. Mounting seat; 4. Laser head, etc.
3.Structure introduction: It can adapt to different specifications of pipes by adjusting the up and down movement of the laser head.
4.Structural advantages: the mechanism is simple, stable and easy to operate.
The Z-axis can be both follow-up and numerically controlled: in order to solve the problem that the laser focus fluctuates due to the uneven surface of the pipe, which affects the cutting quality, the cutting head (Z-axis) must follow to keep the focus constant. In addition to the follow-up function, the Z axis of the cutting machine also has the same display and control functions as the X and Y axis.
Graphic display: The machine has the functions of analog graphic display and dynamic graphic tracking display for the edited part program, which makes the processing more intuitive and easy to monitor and control.
Multiple alarm functions: The CNC system of the machine has the functions of self-checking, alarming and automatic protection, and also has alarm display and automatic protection for external conditions.
CNC control system: The system adopts an integrated structure, central control and display operation unit structure. The system is based on windows CNC system. The display operation unit provides a good man-machine interface and displays various operation information. The operation panel has function keys for machine tool operation.
Low-voltage electrical system: The low-voltage electrical system is located in the electric control cabinet, which is the interface part of the electrical control of the whole machine. The power supply, relays, circuit breakers, contactors, and servo drive systems required by the electrical control system are installed in the electric control cabinet.
Using high-quality stainless steel cold water circulating pump, large flow, high lift, low noise, long life; stainless steel water tank, pipeline, stainless steel valve will never worry about rust.
The control system adopts LCD full Chinese (or full English) computer controller, CPU automatic control, simple and intuitive operation. The control accuracy is as high as ±0.1℃; it has the function of automatic fault diagnosis, which directly displays the fault point on the screen, prompting the user to deal with it quickly. And the fault signal can be directly transmitted to the CNC numerical control system through the data line to avoid damage to components and equipment.
Provides multiple protection functions, passive alarm terminals, and remote control terminals, which are easy to realize centralized control and monitoring of CNC; among them, the "dual temperature type" precision water cooler provides stable and accurate water temperature control for the laser, and also provides a channel with The water temperature similar to the ambient temperature is used for lens cooling, which solves the problem of damage to the lens caused by condensation when cooled with low-temperature water, and is the best choice for cooling the entire laser equipment.
