- 各类汽车中都有12V电池。它是作为内燃机汽车低压配电、后备电源和启停操作的电能来源。
- 48V电池最常见于低速电动车（如两轮电动车）和轻混电动汽车（MHEV）。它的作用是支持启停操作、再生制动和扭矩提升，以及驱动电动机。
- 高压电池最常见于全混电动汽车（FHEV）、插电式混合动力汽车（PHEV）和纯电动汽车（BEV）。最常用的两种高压电池为400V和800V。它的作用是支持启停操作、再生制动和扭矩提升，以及驱动电动机。
在上述所有电池中，电池管理系统的主要作用是，管理、保护和优化电池性能。进一步了解英飞凌完整的电池管理系统解决方案，以及它如何使得电池性能达到最高。

Voltage Classes
12V and 24V batteries
The low voltage batteries include lead acid and lithium-ion batteries, can be found in light passenger vehicles, electric 2 and 3 wheelers, trucks, commercial and agricultural vehicles. They support all types of propulsion systems.
-
Voltage Classes
48V and 72V batteries
These batteries could not only be found in light passenger vehicles and electric 2 and 3 wheelers, but also support the propulsion system of BEV and MHEV. Besides, 48V battery could be used as 3rd voltages.
-
Voltage Classes
400V 800V 1200V batteries
The high voltage batteries support light passenger vehicles, trucks, commercial and agricultural vehicles, as well as energy storage systems. Additionally, they also power the propulsion systems of BEV, PHEV, FHEV, and FCEV.

Subfunctions of BMS
Battery Disconnection
Ensure electric vehicle’s safety during parking, charging, and discharging by disconnecting from the charger when triggered by failure events, or from the battery when the vehicle is off, and monitoring the state of disconnection.
-
Subfunctions of BMS
Battery Pack Monitoring
Maximize performance and protect passengers by thermal runaway detection, battery disconnection monitoring, isolation monitoring and over-current detection (OCD). Additionally, they trigger disconnection units if needed.
-
Subfunctions of BMS
Battery Passport & Event Logging
Log and monitor vital parameters, to derive actual battery information, track back for malfunctions, clarify warranties and support ‘pay-per-use’ business models. Besides, the battery could thereby be performance-tuned or proactively pre-conditioned.
-
Subfunctions of BMS
Battery Controlling
Drive monitoring units to calculate SoC, SoH, SoP and SoS, and communicate with the domain controller. Besides, the battery control units (BCU) perform housekeeping and update the BMS firmware.
-
Subfunctions of BMS
Cell Monitoring & Balancing
Balance cells’ characteristics or the heterogeneous thermal spreads in the final pack by diagnosing the cells’ voltages & temperatures and communicating to the main controller with extreme low-power housekeeping.
-
Subfunctions of BMS
Current Sensing & Coulomb Counting
Trigger the battery protection unit to disconnect the loads from the battery cells with accurate SOC measurement and fast OCD by coulomb counting in battery management systems.
-
Subfunctions of BMS
Isolated Communication
Transmit cell monitored information reliably and safely between isolated high voltage and low voltage domains in the battery, supported by both wired BMS topology: Iso-UART and Wireless BMS topology: Low-power Bluetooth.
