About this novel aforementioned and other content, characteristics and function, the detailed description coordinating below with reference to the preferred embodiment of accompanying drawing can clearly present.
Fig. 1 is the overall architecture figure of electric-vehicle remote monitoring system, electric-vehicle remote monitoring system is by collection, analysis and processing to electronlmobil data in operational process, thereby whole vehicle state, battery status and vehicle location to electronlmobil are monitored, and according to the Real Time Monitoring data with divide the data analysis of platform acquisition from industry after, carry out corresponding early warning and warning for different events.Data mining by the later stage and comparative analysis etc. in detail, reliability, safety, battery cycle life to car load, electrokinetic cell and main parts size are estimated, thus for improve electronlmobil operation maintenance system and the service Development of Electric Vehicles relevant decision-making technical support and integrated information service are provided.
Fig. 2 be in the electric-vehicle remote monitoring system Organization Chart about the concrete structure figure of the battery management system in electric-vehicle remote monitoring system, its testing process is as follows:
Detection for cell in the electronlmobil stack battery realizes by battery management system (BMS).Battery management system adopts the collecting and distributing type system architecture, and every cover battery management system is comprised of 1 Central Control Module (CCM) and 10 battery control modules.Battery management system all will be completed Real Time Monitoring (monitor message comprises charging and discharging currents and number of times, the insulation resistance etc. of voltage, temperature and the battery pack of the cell in the electronlmobil stack battery) and the trouble diagnosing of battery status reliably in the vehicle operating process or in process of charging.By bus mode, real-time battery status is informed the equipment such as entire car controller (VMS) or electric machine controller, in order to adopt more reasonably control policy, reach the purpose of effective use battery, simultaneously, battery management system (BMS) is informed vehicle-mounted monitoring system by bus mode with battery pack information, complete the functions such as the demonstration of battery status data and fault alarm, for maintenance and the replacing of battery provides foundation.
What the cell in the electronlmobil stack battery detected is characterized as:
(1) the battery management system design is based on micro controller system.
(2) realize equilibrium between cell by balance module, improve battery efficiency and life-span on probation.Equilibrium between cell is the cell equalizing charge, be exactly in process of charging, by regulating cell charging current mode, in the assurance system, the voltage of all batteries constantly has good conformability at each, makes that in battery pack, each cell reaches equilibrium state always.
(3) in battery management system, the estimation of battery pack SoC.Real-Time Monitoring capacity of cell in charge and discharge process is estimated the nuclear power state (SoC) of power battery pack at any time, i.e. battery dump energy is guaranteed SoC in rational scope, prevent due to overcharge or overdischarge to the damage of battery.
Detect for the cell in stack battery, principal particulars shows following aspect:
(1) ensure the use secure context, prevent that cell from overcharging or the overdischarge phenomenon.If cell overcharges (refer to that monomer voltage surpasses the upper limit: ferric phosphate lithium cell is 3.65v, and lithium manganate battery is 4.25v), can cause that the battery-heating amount is large, may cause even blast on fire.Substantially all add charge protector in battery management system now, but in order further to ensure safety, in case also can in time find potential safety hazard when guaranteeing circuit malfunction, monitoring cell performance is necessary extremely.
(2) ensure the use secure context, prevent cell excess Temperature phenomenon.The electrokinetic cell working current is large, quantity of heat production is large, and power brick is again the environment of a relative closure simultaneously, and this can cause the rising of battery temperature.The operating temperature of ferric phosphate lithium cell requires below 60 ℃, summer outdoor temperature near 40 ℃, the quantity of heat production of battery own is large simultaneously, this will cause battery operated ambient temperature too high, may cause even blast on fire when serious.For ensuring safety, the temperature of cell is carried out Real Time Monitoring, and real-time report temperature pole alarm message is necessary extremely.
(3) improve the aspect in service life, in time provide the service condition of monomer battery voltage, pick out in-problem battery, keep reliability and the high efficiency of whole Battery pack.Overcharging of cell is certain to make the battery performance descending speed to accelerate, and capacity of cell diminishes, and the life-span reduces.And in stack battery, the life-span reduction of a cell can cause the life-span of whole battery pack to be reduced.In addition, the good bad influence battery pack life-span of consistency of battery pack, estimate conforming parameter wherein one be the standard deviation of monomer battery voltage, also can calculate the state of monomer whose battery by the change of voltage under cell charge and discharge state, judge whether and to carry out independent additional charge, discharge or replacing separately to it.
(4) improve the aspect in service life, in time provide the service condition of cell temperature, pick out in-problem battery, keep reliability and the high efficiency of whole Battery pack.Dense arrangement due to the heating cell body, the inevitable heat accumulation of zone line is more, it is unbalanced that fringe region has increased in the power brick temperature between each cell more at least, this will cause the unbalanced of each battery pack, cell performance, the final conformability of battery performance and the accuracy that battery charge state (SOC) is estimated of affecting, the system that has influence on electronlmobil controls.By the monitoring to the cell temperature, in time send the temperature contrast alarm message, for carrying out adjustment, battery management system prepares.
(5) by the cell in stack battery is detected, set up the use of cell and record archives, for further optimization and development of new battery and improvement battery group technology provide technical materials; For off-line analysis battery system fault provides foundation.
Fig. 3 is cell testing process schematic diagram, and the testing process of the cell in the electronlmobil under mode of operation in stack battery is as follows:
