Integrated Battery Protection
The Alliance Intelligent Battery Series™ battery technology includes integrated
protection circuitry to prevent the battery from certain damaging use conditions. The
battery’s circuitry interrupts either charging or discharging current if the battery is in
danger of exceeding limits to voltage, current, temperature or internal failure of the
BMS.
Transient Energy Limit
The battery is designed to protect itself from transient voltage spikes which contain
excess energy of up to 2.5 Joules. Inductance, inherent in the cabling used to
connect to the battery and the system, stores energy which can be released
suddenly when the battery protection circuit opens. When this occurs, the passive
energy stored in the wiring and active sources like power supplies and battery
chargers can create large transient spikes, that if exceed 2.5 Joules, can permanently
damage the BMS.
While the product has been designed to handle a maximum inductance
of 10 μH
and
tolerate connections to most power supplies, the user is responsible for ensuring that
the battery does not experience over-voltage surge energy in excess of 2.5 Joules
when conduction is interrupted. External energy absorption devices like capacitors or
clamps can reduce the overshoot or stress on the battery and may be required based
on the application. Please contact American Battery Solutions if you have any
concerns or questions regarding Transient Energy and your specific application and
connection.
