Description

A kind of Based Intelligent Control is multi-functional, polymorphic type energy-storage battery quick charging system

Technical field

The utility model relates to energy-storage battery and controls and rapid nitriding field, particularly relates to a kind of intelligent control system polytype energy-storage battery being realized to several functions charging.

Background technology

Energy-storage battery is electri forklift, electric automobile provides power, and energy-storage battery charging-discharging performances directly affects its use and life-span.Energy-storage battery is generally divided into lead-acid battery, nickel-cadmium cell, Ni-MH battery and lithium ion battery and ferric phosphate lithium cell etc.Because the of a great variety and capacity of energy-storage battery differs, and the battery such as lithium ion battery, LiFePO4, single battery can't be adopted and use by battery pack form.Therefore, the energy-storage battery of variety classes and capacity often needs different charging adaptations.

The most influential to it in the use procedure of energy-storage battery is exactly overcharge to battery and overdischarge, and once overcharge, overdischarge, battery will damage, and capacity reduces, and the life-span reduces, and when serious, explosion and catching fire also can occur.Lithium battery monomer capacity is excessive, easily produces high temperature, brings out unsafe factor, and therefore high capacity cell must form battery pack by series-parallel mode.Because battery pack is made up of cell, and the nuance of the state inconsistency of cell itself and environment for use, all can cause the difference of battery life, greatly affect life-span and the performance of whole battery pack.Battery in groups rear main problem has the following aspects: 1) overcharge or cross and put.During batteries charging/the electric discharge of connecting, percentage of batteries may be full of/discharge prior to other batteries, and continuation charge/discharge will cause to overcharge/cross to be put, and the inside side reaction of lithium battery will cause the problems such as battery capacity decline, thermal runaway or internal short-circuit.2) super-high-current.The situations such as in parallel, aging, low temperature all can cause the electric current of percentage of batteries to exceed useful life that its ability to bear reduces battery.3) temperature is too high.The too high meeting of local temperature makes the properties of battery decline, and finally causes internal short-circuit and thermal runaway to produce safety problem.4) short circuit or electric leakage.Because the factors such as vibrations, damp and hot, dust cause battery short circuit or electric leakage, threaten the personal safety of driver and crew.

BMS (battery management system) as the electronic unit of monitoring, automatic equalization, intelligent recharge and discharge in real time play ensure safety, the critical function such as life-saving, estimation dump energy, be vitals indispensable in power and energy-storage battery group.BMS function needs the operating state of dynamic monitoring power battery pack, the terminal voltage of the every block battery of Real-time Collection and temperature, charging and discharging currents and power brick total voltage, estimate the state-of-charge (state of charge SOC) of each battery, safe condition (state of health SOH) and electrochemical state (state of electroformation SOE), then by controlling other devices, prevent battery generation overcharge or overdischarge phenomenon, battery condition can be provided in time simultaneously, and pick out problematic battery, keep whole Battery pack reliability of operation and high efficiency.
