In the design of the on-line monitoring and management system of the battery group, the influence of various occasions and accidents on the system itself and the equipment matching with the system should be considered. The system adopts the means of impact resistance, high fault tolerance and high performance components, which makes the system have high security performance. It has good independent operation ability, is not affected by the working conditions of the user system, and does not affect the working state of the user system.
The following 6 items are available for the safety of the battery on-line monitoring system:
One, with anti-overvoltage overcurrent high frequency magnetic field interference technology
Battery on-line monitoring and management system using advanced Power conversion technology, wide operating voltage range, anti-over-flow pressure capability, the system design has anti-surge circuit, can be in high-frequency strong magnetic field working environment normal operation.
Second, electromagnetic compatibility
The on-line monitoring and management system of the battery fully considers the characteristics of electromagnetic compatibility in circuit design and structure design, and the electromagnetic radiation quantity is less than national standard. With metal casing, it has good shielding effect. The system itself does not have any electromagnetic interference to the outside world.
Third, on-line maintainable technology design
The battery on-line monitoring and management system adopts modularization design, module Independence is good, online maintenance is strong, online maintenance does not affect the normal work of the user system.
Four, flame retardant design
The battery on-line monitoring and management system adopts the components with good flame-retardant characteristics, and the fault caused by the short-circuit of the system itself will not cause flame burning.
Five, explosion-proof design
Battery on-line monitoring and management system using electronic relays, no channel switching sparks, no open flame contact connection device, can be used for high explosion-proof requirements of the petrochemical industry.
Six, System fault tolerance
Meter to the charging system and working circuit should be without any interference, the module with the battery connection part should be anti-overcurrent insurance, to avoid connecting the wire itself short circuit or module fault damage to the battery. Each detection channel should adopt high impedance input method, the current of the detection circuit is less than the micro-safety, should not have any adverse effect on the battery. The connection of the module with the battery is single-wire connection, the connection end is installed over-current insurance, to avoid the connection wire itself short-circuit or module fault damage to the battery. The use of small power components design, the system operating low power consumption, the user power supply system requirements are not high, does not affect the user supply lines. Work completely independently of the user's device.
