5A fuses protect Li-ion batteries from overcharging
Littelfuse, Inc. announced the extension of its ITV2718 surface-mountable Li-ion battery protector series. These fuses safeguard Li-ion battery packs against overcurrent and overcharging (overvoltage) conditions—even when fast charging. The latest addition, the ITV2718, provides a five-amp, three-terminal fuse in a 2.7 x 1.8 mm footprint. The innovative design utilizes an embedded fuse and heater element combination…
What is the EV battery supply chain?
The electric vehicle (EV) battery supply chain is vast and complex, spanning mining and processing to assembly and end-of-life management. This article reviews the supply chain’s four primary stages: upstream, midstream, downstream, and recycling or repurposing. It also highlights major supply chain challenges and explores potential solutions to improve resiliency, efficiency, and sustainability. Defining the…
Liquid cooled battery charger available in compact form
Bel Fuse Inc. is announcing the release of its BCN25-1000 Series — a 25 kW, liquid-cooled battery charger that converts 3-phase AC voltage to DC voltage.
Active clamp flyback controller integrates adaptive digital pwm control with ultra-high-voltage components
Silanna Semiconductor has expanded its CO2 Smart Power Family of AC/DC and DC/DC converter technologies with the launch of an active clamp flyback (ACF) controller that integrates adaptive digital PWM control with ultra-high-voltage (UHV) components comprising a 700 V primary GaN FET, X capacitor (X-Cap) discharge circuit, active clamp driver and start-up regulator. Silanna’s CO2 […]
TTape: A simple way to monitor Li-ion battery-pack temperature
A set of temperature-triggered switches alerts you to hot batteries. Li-ion batteries can get hot, which can cause failures or worse in the products they power. Thus, it’s important to monitor their temperature and act before damage occurs. You can monitor temperature with a set of thermocouples, scan them, and write software to produce an […]
Current sense resistors feature low TCR
Bourns, Inc. introduced four high-power, ultra-low ohmic current sense resistor series. The latest current measurement devices from Bourns are designed to help save energy while maximizing sensing performance in power electronics designs. The four CSI Model Series feature low-temperature Coefficient of Resistance (TCR) for operating accuracy over a wide temperature range and excellent long-term stability. Their […]
What does a digital twin mean for a BMS?
A digital twin (DT) generally refers to a digital representation of a physical object, system, or process. The idea of creating a DT is to replicate a real-time model of a physical entity. While trying to make a real-time model, the various aspects of the physical entity, such as properties, behavior, and status, are considered. […]
