The difference between starting the battery and the battery for uninterruptible power supply
UPS (Uninterruptible power system), uninterruptible power supply system, power off to the battery, completely uninterrupted, or within 10 microseconds conversion. Do not need to restart the use of electricity, continue to use.
EPS, is the DC switch search AC inverter. EPS (emergency power system) is the Chinese manufacturers themselves about 1998 or so marketing terms. Mainly for power and lighting power in the power off, do not start the generator, and with a straight AC inverter from the battery. No strict conversion time requirements, and even some manual switching.
Start with the characteristics of the battery Summary:
1 large current discharge: high current discharge capacity, energy conversion efficiency, process loss is small, high current energy cycle efficiency ≥ 90%
2 ultra-low resistance
3 ultra-resistant wide temperature: ultra-low temperature characteristics, the temperature range of -40 ℃ ~ +70 ℃;
4 long life: the depth of charge and discharge cycles up to 1 to 50 million times, there is no "memory effect."
Lithium-ion battery / lead-acid battery / nickel-metal hydride, battery-borne, battery-mounted, lighting, ignition (abbreviated as SLI) and power supply (SLIG abbreviated as SLIG in the 1980s) Nickel - cadmium batteries. Generally refers to the car battery (automobile battery), or call the car to start the battery. More than the rated capacity of the rated battery C about 36 ~ 210A · h, forming a series, the specific energy of 35 ~ 45W · h / kg (according to 20h discharge rate of energy). Can discharge several times the discharge rate of C discharge.
Uninterruptible power supply battery: the battery (mostly lead-acid maintenance-free battery) connected with the host, through the host inverter circuit modules such as direct current into the mains of the system equipment. Mainly used for a single computer, computer network systems or other power electronic equipment such as solenoid valves, pressure transmitters, etc. to provide a stable, uninterrupted power supply. When the mains input is normal, the UPS will be powered by the mains supply to the load, this time the UPS is an AC mains regulator, and it also charge the battery to the machine; when the electricity interruption (accident power failure) , The UPS immediately to the battery DC power, through the inverter zero switching method to continue to supply 220V AC load, so that the load to maintain normal work and protect the load soft, the hardware is not damaged. UPS equipment is usually too high voltage or voltage can provide protection.
