Description
Technical field
The present invention relates to Dynamic Test Transient activity of force compensator and compensate method of supplying power to, belonging to Circuits System technical field.
Background technology
For power-type power unit, adopting the lead-acid accumulator that capacity is bigger at present is its power supply as energy unit, and power-type power unit needs Transient Currents when starting, required transient state high power requirements is started for meeting power-type power unit, have to " excess configuration " lead-acid battery, make battery not only big but also heavy, not only waste resource but also uneconomical. Simultaneously because power-type power unit starting current is bigger, the rush of current of lead-acid accumulator is bigger, positive plate active substance is caused to come off, lead-acid battery pool-size is declined very fast, service life shorter (being generally 2～3 years), change comparatively frequent, increase subscriber equipment maintenance workload and use cost. And the main sulfur acid of lead-acid accumulator and heavy metal lead, ecological environmental pollution is very big, bring again high old and useless battery to reclaim, the risk of the social cost such as disposal and environmental pollution.
For internal-combustion engine vehicle, accumulator is one of requisite power supply of internal-combustion engine vehicle as energy unit, powers to startup motor when vehicle explosive motor starts; When electromotor does not work or electromotor works under not high rotating speed, accumulator is powered to non-power type power unit; When non-power type power unit power exceedes TRT power, accumulator is powered to non-power type power unit with generator combined.
