ams AG Introduces Cost-Saving System Management Reference Design for Lithium Pedelec/e-Bike Batteries

ams AG introduced an example design for lithium pedelec/e-bike batteries which implements accurate cell monitoring and balancing without the need for a microcontroller in the Battery Management System (BMS). Battery pack and pedelec manufacturers which use the design will benefit from valuable bill-of-materials (BoM) cost savings and a simpler circuit design, compared to batteries in production. The ams design is for a 48V pedelec battery consisting of up to 14 lithium-ion cells. It uses two AS8506 smart cell monitoring ICs, with few supporting components, to monitor the temperature and voltage of up to seven cells each and to implement passive balancing of the cells when charging. By contrast, conventional BMS designs in pedelecs use dumb voltage monitoring ICs to measure the voltage and temperature of cells, reporting the values to a dedicated battery management microcontroller via a serial communications link. The MCU is required to control safety and protection functions (over- and under-voltage and over-temperature shut-down) and cell balancing. The AS8506 from ams, however, includes built-in logic functions for controlling cell safety, protection and balancing. These functions can easily be configured by the user, with the settings saved in an on-board OTP memory. The device also features integrated MOSFETs for use in passive cell balancing operations. During charging, each cell's voltage is compared to a user-programmable reference voltage threshold. Up to 100mA may be discharged through the MOSFET from any cell exceeding the threshold, until all cells have reached the threshold and the battery module is fully charged. This architecture, in which battery monitoring and cell balancing operations are implemented inside the AS8506 voltage-monitoring device, dispenses with the dedicated MCU required in conventional pedelec battery designs. When an AS8506 detects an over- or under-voltage or over temperature condition, an interrupt signal is transmitted to the pedelec's motor controller IC to complete the required safety shut-down operations. The reference design can be used in any pedelec or e-bike battery containing up to 14 lithium-ion cells. It can also be extended to supervise more than 14 cells by daisy-chaining additional AS8506 ICs as required. The reference design files are available on request from ams. It is priced at $9.10 for 1,000 pieces.
