Grid converter puts locally generated power on power grids
Siemens presents a new power conversion system for battery storage applications. The SINAMICS PCS grid converter makes locally generated batter power usable for industrial and public power grids. SINAMICS PCS controls the charging and discharging process of the battery and helps to handle load peaks and grid disturbances via the battery storage, to store the […]
High-current jumpers handle up to 7 A
Electronic circuits frequently require zero-ohm jumpers for ease of manufacture or to make trace routing easier. Some of these applications require current handling that exceeds the capabilities of general-purpose or high current jumpers. Stackpole’s HCJ series offers more than double the current rating of comparable high current jumpers. The HCJ current ratings range from 5.8A for […]
PXI, multi-cell battery simulator modules target automotive and aerospace applications
Pickering Interfaces launched a new family of battery simulator modules, ideal for Electric Vehicle (EV) battery stack emulation in Battery Management Systems (BMS) test applications. The 41-752A (PXI) and 43-752A (PXIe) modules enable direct voltage and current readback either programmatically or using Pickering’s soft panel control. Each cell simulator is highly accurate, specified at ±5 mV from 1 […]
1.5kW ac-dc power supplies offer CV and CC operation
Two new single-phase 1.5kW AC-DC power supplies from XP Power offer programmable constant voltage (CV) and constant current (CC) operation with analog and digital interfaces for user control. The compact and convenient solutions use an efficient resonant zero-volt switching (ZVS) topology and are suitable for equipment manufacturers in a wide range of industries including industrial, […]
BMS technology shows 60% increase in battery lifetime, 129% increase in storage capacity
Brill Power, an Oxford University spin-out company, launched “intelligent” battery management systems (BMS) incorporating technology designed to transform the cost and performance of energy storage systems by increasing battery life by up to 60 percent, enhancing storage capacity by up to 129 percent, increasing systems uptime, and driving down the lifetime operating costs for energy […]
Nanopower primary cell monitor incorporates precision coulomb counter
Analog Devices, Inc. new LTC3337 is a nanopower primary (non-rechargeable) cell State-of-Health (SoH) monitor with precision coulomb counter, designed to be placed in series with a primary battery with minimal associated series voltage drop. The patented infinite dynamic range coulomb counter tallies all accumulated battery discharge and stores it in an internal register accessible via […]
Battery management system targets robotics, AGV, 2/3-wheeler apps
The new i-BMS Battery Management System from Lithium Balance, acquired by Sensata earlier in the year, is a cell chemistry agnostic, compact, integrated BMS developed for the cost-optimized mass-production of applications up to 60 V, such as two and three-wheelers, automated guided vehicles (AGVs), and robotics. The i-BMS is a long-term solution for customers who […]
Redrivers meet modern standby mode requirements
Diodes Incorporated has introduced the PI3EQX12902E/PI3EQX12904E to further strengthen its ReDriver product offering. These ReDrivers meet the Modern Standby mode requirements as outlined by Microsoft Corporation, and deliver elevated linearity and ultra-low jitter characteristics now expected in laptop, notebook, industrial PC, and embedded system designs. Operating from a 3.3V rail and in standby mode, the […]
