Description
Technical field
The present invention relates to a kind of storage battery and for monitoring the method for storage battery and there is the battery system of storage battery.The invention still further relates to a kind of means of transportation, particularly automobile, as having electric automobile or the hybrid vehicle of storage battery or battery system.
Background technology
Predictably, no matter be in this stationary applications of such as wind power plant, or at such as electric automobile (electric vehicles, or hybrid vehicle (hybrid electric vehicles EV), HEV) this Mobile solution aspect, as rechargeable accumulator, such as, adopt the application of the new battery system of lithium ion battery or nickel metal hydride battery growing.
Battery system must meet very high requirement in available accumulation of energy (energy content), charge/discharge efficiency, reliability, useful life and undesirable capacitance loss of being caused by partial discharge frequently (memory effect Memory Effekt).
Battery system comprises a large amount of storage battery list ponds.According to its single pond internal resistance and the electrochemical process carried out, storage battery list pond temperature during charging and discharging rises.Can be connected (Serie) in storage battery list pond, to improve voltage and/or parallel connection, to improve maximum current.In this regard, storage battery list pond can be merged into secondary battery unit or battery module.For driving in means of transportation, such as can serial or parallel connection about 100 storage battery list ponds (as traction accumulator).In high voltage electric storage cell system, total voltage can be such as 450V or even 600V thus.
Storage battery list pond is run the temperature range allowed and is typically between-30 DEG C to+70 DEG C, preferably between+5 DEG C to+35 DEG C.In the lower ranges of working temperature, the power in storage battery list pond obviously declines.When temperature is lower than about 0 DEG C, the internal resistance in storage battery list pond acutely rises, and the power efficiency in storage battery list pond declines continuously along with the further reduction of temperature.Meanwhile, also there will be the irreversible damage in storage battery list pond.When exceeding working temperature, the power in storage battery list pond also can obviously decline.When temperature exceedes about 40 DEG C, the useful life in storage battery list pond reduces.Meanwhile, there will be the irreversible damage in storage battery list pond equally.In addition, the temperature difference (temperature gradient) that the operation in storage battery list pond and/or the storage battery list pond of battery module or internal storage battery allows typically is between 5 Kelvins to 10 Kelvins.In larger temperature difference situation, different loads or even (locally) overload and/or damage can be born in the zones of different in storage battery list pond or the different batteries list pond of battery module or storage battery.In addition, because the temperature difference and/or variations in temperature exist in storage battery the danger forming condensed water.Damage can cause the accelerated ageing in storage battery list pond or the thermal runaway (Thermal Runaway) in storage battery list pond, threatens the person and environment structure.
In the hybrid drive train of means of transportation, lithium ion high-power battery list pond is run with very high power.During the peak load of the short time such as produced by braking energy during recovery braking or supercharging support when accelerating, storage battery list pond must absorb (during charging) or export (during electric discharge) high power within the very short time.Due to the internal resistance in storage battery list pond, the peak load of this short time causes storage battery list pond to be obviously heated.During charging or electric discharge time storage battery list pond efficiency very high (about 95%); But the used heat meanwhile produced can not be ignored.When the traction power of such as 60KW, the loss of 5% produces the loss power of 3KW.In addition, such as, can reach 40 DEG C and higher torrid areas in summer or outdoor temperature, the temperature range of permission can be exceeded, thus when storage battery list pond does not cool, not reach such as 10 years useful life.
For ensureing the fail safe of battery system, function and useful life, therefore require that storage battery list pond is run in prespecified temperature range.On the one hand as mentioned above, the heat that the run duration in storage battery list pond produces must be discharged, and is heated above critical maximum temperature with what avoid storage battery list pond.On the other hand, require that storage battery list pond can be heated to minimum temperature at low temperatures.Battery system is monitored, to observe prespecified temperature range and/or to identify interference.
For monitoring by temperature management system, the temperature in storage battery list pond is by temperature sensor, such as thermistor (temperature) sensor (negative tempperature coefficient thermistor transducer (Negative Temperature Coefficient) (NTC) thermistor, NTC transducer, there is the resistance of negative temperature coefficient, NTC resistance), semistor transducer (Positive Temperature Coefficient (PTC) thermistor, PTC transducer, there is the resistance of positive temperature coefficient, PTC resistance) or infrared sensor (Infiared Sensors, IR-Sensoren) measure.Temperature sensor such as can be fixed on the electric wiring or upper or by the connector of interconnective for wiring single pond in storage battery list pond, storage battery list pond.
DE 10 2,010 062 207 A1 describes a kind of device with temperature sensor unit, for detecting the temperature of electrochemical energy accumulator, particularly uses on automobile.Accumulator comprises one or more storage element, and these storage elements have respective two binding posts connected for its electric contact, are connected by wiring element electric contact.For detecting the temperature corresponding to the internal temperature of storage element, the respective temperature sensor of temperature sensor unit is arranged on the binding post of at least one storage element of accumulator.
For improving battery system, the fail safe of such as lithium-ions battery system, function and useful life, therefore require to improve the monitoring to battery system.
