rate being measured. A 40mA BCI test level is sufficient for
most industrial applications. The 200mA test level is typically
used for automotive testing. The Bourns® Model SM91501AL
and SM91502AL have been evaluated by certain BMS IC
manufacturers for select automotive applications and have
successfully passed BCI requirements.
Summary and Conclusions
Li-ion battery power demand is predicted to grow at a
CAGR of 20 percent to 30 percent over the next eight
years. Battery Management Systems that integrate isolated
communications are expected to be an important part of
the battery system's safety and security. An effective and
reliable BMS will help increase Li-ion cells' lifespan while
also enhancing safe operation for end-users.
Offering an optimal protection solution for isolated
communications in industrial and consumer BMS
applications, Bourns engineered its latest Model
SM91501AL and SM91502AL BMS transformers with the
higher working voltages of 1600V and 1000V, respectively.
They feature an inductance value of 150µH and 450µH over
an operating temperature range of -40˚C to + 125˚C, which
meets higher voltage BMS requirements. Additionally, the
transformer windings use fully insulated wire passing the
dielectric strength (Hi-POT) test, further increasing electrical
insulation protection for overvoltage transients.
Bourns® Model SM91501AL and SM91502AL have
been tested by several BMS IC companies in their test
laboratories which found them to function well with their
chipsets, passing the necessary BCI tests. ■
