What is bms

BMS is a system that implements comprehensive management of building equipment monitoring systems and public safety systems.

bms is the abbreviation of construction equipment management system. BMS Building Management System is a system that implements comprehensive management of building equipment monitoring system and public safety system.

BMS system is a battery management system, which is the link between the battery and the user. The main target is the secondary battery, which is mainly to improve the utilization rate of the battery and prevent excessive charging and overdischarge of the battery. It can be used for electric vehicles, battery vehicles, robots, drones, etc.

Battery management system (BMS) can manage the battery system safely, reliably and efficiently.By collecting battery module data, uploading to the monitoring platform, and through the three-level fault protection system and the control of the external main loop relay, the system realizes protection of cell overvoltage, high and low temperature, charge and discharge overcurrent, etc.

What aspects does the battery energy storage system include

Energy storage equipment Energy storage equipment is the core component of the energy storage system used to store energy in electrical, chemical or physical form. Common energy storage devices include storage batteries, supercapacitors, compressed air energy storage, fuel cells, etc.

The energy storage system is composed of batteries, electrical components, mechanical support, heating and cooling systems (thermal management system), two-way energy storage converter (PCS), energy management system (EMS) and battery management system (BMS).

Lithium battery energy storage system technology relies on two aspects of technology: the world's leading new energy power conversion technology and first-class lithium battery technology, and develops energy storage transformers, lithium batteries, energy management systems and other energy storage core equipment.

Introduction to the electronic control system of new energy vehicles

Theoretically, new energy vehicles can be divided into three categories: plug-in hybrid vehicles, pure electric power vehicles, and fuel cell power vehicles, so each type The electronic control systems will also be different because of the different driving methods, and the departments they include are also different.

The electronic control system is the brain of a pure electric vehicle, which is composed of various subsystems, and each subsystem is generally composed of sensingIt is composed of instrument, signal processing circuit, electronic control unit, control strategy, actuator, self-diagnostic circuit and indicator light.

The electronic control system should have high control accuracy and high dynamic response rate, and provide high safety and reliability at the same time. As an important link in the new energy vehicle industry chain, the technology and manufacturing level of the motor electronic control system directly affect the performance and cost of the whole vehicle.

The importance of motor electronic control. As a substitute for traditional fuel vehicles, the main electrical system of new energy vehicles is the "three electricity" of electric powertrain system extended on the basis of traditional automobile "three small electricity" (air conditioning, steering, braking) - battery, motor, electronic control.

The motor drive control system (including the drive motor and motor controller) is the main execution structure in the operation of new energy vehicle vehicles. The control and drive characteristics determine the main performance indicators of the vehicle driving.

What does battery management system mean?

1. bms system refers to the battery management system (English: Battery Management System), which is a system that manages batteries. BMS is mainly for intelligent management.And maintain each battery cell to prevent overcharging and overdischarging of the battery, extend the service life of the battery, and monitor the status of the battery.

2. BMS (battery management system) is simply a switch that controls the negative pole. It is the CPU (central processing processor) of the lithium battery pack. Through the collection of the voltage, current, temperature and other parameters of the battery pack, it monitors and judges the status of the battery pack.

3. The BMS system is a battery management system, which is the link between the battery and the user. The main target is the secondary battery, which is mainly to improve the utilization rate of the battery and prevent excessive charging and overdischarging of the battery. It can be used for electric vehicles, battery vehicles, robots, drones, etc.

Lithium iron phosphate battery system?

1. The full name of lithium iron phosphate battery is lithium iron phosphate lithium ion battery, or lithium iron phosphate battery for short. Because its performance is particularly suitable for power applications, the word "power" is added to the name, that is, lithium iron phosphate power battery. Some people also call it "LiFe power battery".

2. Ultra-long life, the cycle life of long-life lead-acid batteries is about 300 times, and the maximum is only 500 times. Domestic lithium iron phosphate power batteries have a cycle life of more than 2,000 times, and the standard charging (5-hour rate) can reach 2,000 times.

3. Advantages of energy storage lithium iron phosphate batteries The lithium iron phosphate battery has a long life, with a cycle life of more than 2,000 times and a 3C cycle life of more than 800 times. Use it safely.Lithium iron phosphate batteries have undergone strict safety tests and will not explode even in violent collisions. Fast charging.

4. Life improvement lithium iron phosphate batteries refer to lithium-ion batteries that use lithium iron phosphate as the positive electrode material. The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is only 500 times, while the cycle life of lithium iron phosphate power batteries reaches more than 2,000 times, and the standard charging (5-hour rate) can reach 2,000 times.
