Toshiba Electronics Europe (TEE) has announced it will launch a Li-ion battery monitor chipset for automotive applications. Toshiba will start sample shipments of this chipset in February 2013, and mass production in April 2014.
Designed for Hybrid Electric Vehicles (HEVs) and Electric Vehicles (EVs), the Li-ion battery monitoring chipset comprises the TB9141FG monitoring IC and the TMPM358FDTFG microcontroller. The chipset detects remaining battery level, equalizes battery levels (cell balancing) and can detect abnormal battery status.
The TB9141FG will be the industry’s first monitoring IC that is able to monitor up to 16 cells, which can lead to component count reduction in a battery monitoring system. Furthermore, the TB9141FG is able to communicate in a noisy environment by differential signals using daisy chain communication with neighbouring TB9141FGs.
The TMPM358FDTFG is a 32-bit RISC microcontroller built around an ARM CortexTM-M32 core and compliant with functional safety levels (IEC61508 / ISO26262).
Toshiba will prepare a software library to be compliant with the IEC61508 and ISO26262 functional safety standards and is also planning reference models. These tools will simplify the implementation of battery monitoring systems.
