Maxim has introduced the multi-cell lithium-ion (Li +) battery of high pressure, the protection of 12 channels of the battery MAX11080 IC. The device is available on the market first fault monitor can be cascaded to provide control functions, battery to prevent the Li + to explode (overheating). MAX11080 can be daisy-chain up to 31 connections to control as much as 372 cells. This feature can prevent a cascading electrical failure,Dell Studio 15 battery , and eliminating the need for expensive isolation devices separate programs. In a typical hybrid vehicle applications, the program of Maxim’s reduction of 80% of the management system of the battery (BMS) costs.
MAX11080 high precision, low power, integrated security and the auto-diagnosis, and may be configured to function more effectively resolve the security of the large capacity battery monitoring related issues. The device is ideal for automotive, power lines and battery backup systems and other cells.
The development of clean energy has led the unprecedented development of the storage market energy
Transportation to the intelligent network storage technologies for energy from conventional fuels to clean energy transformation is essential. Consumers and governments in the world of green energy, attention, the market for storage of energy, an unprecedented development. Lux Research predicted that by 2012 the energy storage market to grow 55% to $ 64 billion. Among them, the storage market power transmission for hybrid electric vehicles to benefit from (HEV) demand growth, from U.S. $ 12.9 billion in 2007 increased to 19.9 billion dollars in 2012 *.
Energy Technology lithium-ion - a volatile market
In the future fuel, HEV battery will drive the next generation of transportation systems for the most part.
Although the early use of the HEV Ni-MH (NiMH) batteries, but Li + battery with its high energy density and a wide range of single-pilot, who should by 2015 a leading position in the market. Lux Research estimates sales of Li +, from $ 6.8 billion in 2007 jumped to 16.9 billion dollars in 2012.
However, Li + battery obviously unstable, requiring careful design and monitoring programs for advanced security. Battery voltage may cause the increase in battery temperature, which leads to overheating of fuel leaked out of control. Like hundreds of HEV batteries generally supply series, the consequences are not serious: a failure of the battery may cause fire or explosion battery.
Challenge: reduce security costs
Now, put the battery designer a lot of time and resources for ensuring the absolute safety of its batteries. sony vgp-bps8 , The usual protection circuits have been powered by more than 3 or 4-channel monitors, and monitor and analog circuits and passive components (resistors, multiplexers, etc.) at high current isolators. These circuits bulky, expensive, not counting the time spent.
MAX11080 greatly simplify the design of the multi-cellular. Device Fault monitor has 12 channels, using a capacitor ownership link Chrysanthemum isolated population, significantly reduces the number of components, reducing costs. This unique architecture allows the device to connect up to 31 batteries in series, on the screen as much as 372 cells. Meanwhile, the interface of capacitors based insulation provides very low cost of the battery, which eliminates the cascading power failure.
By eliminating the costly isolation devices Maxim’s program to save 75% of the discrete space program, the typical cost management system reduced battery of 250 U.S. dollars to 50 dollars.
MAX11080 set new performance standards
In addition to cost savings, Maxim’s programs also have excellent properties.
high voltage devices, the BiCMOS process small to achieve the highest withstand voltage (80V), excellent ESD performance (± 2 kV human body model), and the ability to hot swap in the range wide operating temperature of the reliability performance. To prevent overheating of the battery, precision overvoltage detection in the AEC-Q100 MAX11080 Class 2 Range of temperature (-40 ° C to +105 ° C) in the error less than ± 25mV.
In addition, MAX11080 can be energy consumption 10 times lower (current operating mode is 80μA), to extend the life of the battery. Single integrated circuit in the stop can be reduced to very low energy consumption, only 2μA, the battery can be stored for several years, but consumes very little battery power.
flexible features
MAX11080 overvoltage threshold of tolerance with 16 and 8 minimum threshold voltage options. Can and should close the detection voltage. detection devices, including programmable delay feature that lets users filter the transitional measures of the battery to prevent power surges or under voltage alarm. alarm line with 4kHz signal pulse, the signal disappeared, which took place against surges actual event or voltage. These characteristics distinguish between right and wrong for the police is very useful to prevent unnecessary shutdown.
The design for automotive applications
MAX11080 on chip with self-configuration and self-diagnostic mode. The device automatically detects when the battery status, and be able to configure any connection order or install monitoring MODE 2 to 12 batteries. comparing device also has internal self-test circuit, when power to ensure its effective functioning. sony vgp-bps9 , Arrangements for monitoring all packets pin open or short circuit, and can continue to track pin failure.
