Batteries are used to power everything from smartphones and power tools to electric vehicles. Depending on the required energy and associated dis-/charge currents, the battery pack is an assembly of individual li-ion cells connected in series and in parallel. A battery cell delivers approximately 4 V. A complete 400 V battery pack, for instance, features about 100 cells. As the cell chemistry is very sensitive to the exact dis-/charge current, voltage profile and temperature profile, the battery requires special monitoring and control capabilities. This is the role of the battery management system (BMS). The BMS monitors and balances each cell. It senses temperature, pressure, current and voltage, measures charge capacity (by counting coulombs) and tracks many other diagnostic metrics. Based on these parameters, it calculates – among other things - the state of charge (SoC), the state of health (SoH) and the precise consumption to predict how much energy is left for the application.

In addition, the BMS controls the main switch to protect the battery against critical overloads. In the event of thermal runaway, the BMS can derate or shut the battery down.

OPTIREG™ automotive power supply ICs for linear, switcher and PMIC devices:

Standard network protocols like CAN (Controller Area Network) and FlexRay are used for data exchange between the battery and external applications. Especially in vehicle battery applications, safety-related self-testing and monitoring functions increase the amount of time-critical data exchanged between the BMS and the ECUs. The automotive industry established the CAN FD (Flexible Data rate) protocol to accelerate CAN communications up to 5 Mbit/s, and the CAN PN (Partial Networking) method to improve energy efficiency. Our broad portfolio of automotive transceivers supports these protocols and methods while meeting and even exceeding the latest ESD and EMC requirements.

Active thermal control is essential with high-voltage li-Ion batteries to avoid accelerated aging, reduced capacity even damage to the battery.

We offer various embedded motor controllers with in-built diagnostic functions supporting active thermal control solutions at pack level. These motor controls come in the smallest form factors with a minimum number of external components so they can be integrated close to the motor. They are based on our 32-bit microcontroller with embedded non-volatile memory, analog/digital peripherals, communication interfaces and integrated current-controlled bridge drivers.

Cryptographic measures such as secured storage of certificates and keys help ensure that the battery management system “is only doing what it is supposed to do”. Cryptographic technologies can securely encrypt over-the-wire/-air software updates, store BMS-related sensitive data such as usage profiles, identify genuine or authenticated parts and components, and verify that a battery configuration remains within its intended design and operational limits. In addition, they can contribute to business success by protecting the IP of core BMS operation software.
