Welcome to a laptop battery specialist of the Hp laptop battery
TOKYO-Toshiba Corporation (TOKYO: 6502) today announced it will launch a lithium-ion battery monitor chipset for automotive applications. The battery monitor IC integrated into the chipset is the industry's first1 to be able to manage up to 16 cells per 1 IC, allowing for a reduction of components and the development of simple, low cost battery monitoring systems.
The chipset, which integrates a battery monitor IC (TB9141FG), and microcontroller (TMPM358FDTFG), detects the remaining charge level and equalizes it among cells (cell balancing) and can also detect abnormal battery status. It is an ideal choice that delivers enhanced battery management technology which is required for hybrid electric vehicles (HEVs) and electric vehicles (EVs).
The TB9141FG uses 96V high-voltage process and realizes monitoring of a 16-cell Li-ion battery such as Hp Pavilion DV1000 battery (Hp dv1000 battery ), Hp PF723A battery , Hp 367759-001 battery , Hp PM579A battery , Hp Pavilion DV4000 battery (Hp dv4000 battery ), Hp Pavilion ZE2000 battery (Hp ze2000 battery ), HP Compaq NY221AA Battery , HP 537626-001 Battery with a single IC. The TB9141FG is able to communicate in a noisy environment, using differential signaling in a daisy chain communication link between two or more TB9141FGs, an important feature for automotive applications.
