A extremely customisable battery administration system (BMS) with ASIL-C certification will make bigger automobiles resembling buses and vehicles extra safer.
Sensata Applied sciences has launched a battery administration system (BMS) IC, the Lithium Steadiness n3-BMS. The BMS is developed for prime voltage purposes with energy as much as 1000 volts/2000 amps, particularly for battery makers and producers of electrical vehicles, buses, and different heavy business automobiles. The BMS comes with purposeful security certification, considerably lowering the time to market and prices related to the ISO 26262 certification course of. This BMS is a distributed system that’s able to monitoring numerous cells utilizing Cell Monitoring Items (CMU). The n3-BMS employs 30 CMUs for monitoring particular person cells and a Grasp Management Unit (MCU), which acts because the host system and consolidates the knowledge and controls the battery capabilities.
Because of many battery-related accidents which have occurred within the EVs, each authorities and customers are demanding for a extra sturdy battery pack. And BMS being probably the most important part requires particular consideration. Subsequently, the demand for ISO 26262-certified parts is on the rise as battery packers and electrical business automobile OEMs prioritize purposeful security of their platforms whereas striving for quicker time-to-market. For the reason that Lithium Steadiness n3-BMS is Automotive Security Integrity Degree (ASIL C) licensed, it reduces the event time and related prices.
In response to the corporate, the BMS firmware has a singular layered software program construction that enhances the benefit of customization of the battery administration system with its personal code and algorithms with out impacting the ASIL C certification. The BMS software program structure consists of a “Base Software program Layer” (BSW) and an “Exterior Software program Layer” (ESW) that are related by an open API hyperlink layer.
The BMS is suitable with the corporate’s earlier technology BMS, so builders engaged on next-generation, heavy electrical automobiles this BMS offers a handy and cost-effective pathway to realize an ASIL C licensed BMS with a easy improve
Key options of the n3-BMS:
- As much as 1000V / 2000A
- 24 – 360 cells in sequence
- 3 CAN ports
