Xscend's high-voltage gate drivers, precision sensing, and intelligent power management enable the next generation of grid-scale and commercial energy storage systems with unmatched efficiency, safety, and reliability.
Grid-scale battery energy storage systems are growing at an unprecedented pace as utilities and commercial operators deploy large-format lithium-ion installations to stabilize renewable-heavy grids. These systems span architectures from 48V residential units to 1500V DC bus commercial and utility-scale deployments, each requiring sophisticated electronics to manage thousands of individual battery cells safely and efficiently.
Precise cell balancing, comprehensive thermal management, and continuous safety monitoring are non-negotiable requirements across every cell in these massive arrays. State-of-charge and state-of-health estimation algorithms depend on millivolt-level measurement accuracy, while fault detection systems must respond in microseconds to prevent thermal runaway cascades that can compromise entire installations.
Traditional battery management system designs rely on dozens of discrete analog components, isolated power supplies, and separate communication interfaces, driving up BOM complexity and manufacturing cost. Xscend's integrated semiconductor solutions consolidate these functions into purpose-built ICs that dramatically reduce component count while improving measurement accuracy and system reliability.
By combining precision analog front-ends with integrated gate drivers and intelligent power management on advanced process nodes, Xscend enables higher power density in DC-DC converter and inverter stages. More accurate state-of-charge estimation extends usable battery capacity, while tighter cell balancing improves cycle life and maximizes the return on investment for energy storage deployments.
Large-scale energy storage systems present demanding requirements for the semiconductor solutions at the heart of battery management and power conversion.
ESS architectures operating at 800V to 1500V DC require robust galvanic isolation between the high-voltage battery stack and low-voltage control electronics. Maintaining measurement accuracy and communication integrity across this isolation barrier is critical for both safety certification and reliable long-term operation.
Thousands of individual cells must be continuously monitored for voltage, temperature, and impedance with millivolt-level accuracy to ensure safe operation. Even small measurement errors compound across large series-parallel arrays, leading to imbalanced cells, reduced capacity, and accelerated degradation.
Preventing thermal runaway requires real-time temperature monitoring and intelligent cooling control across large battery arrays. The BMS must detect localized hotspots within seconds and coordinate active cooling responses to maintain safe operating temperatures throughout the entire installation.
Purpose-built silicon addressing every critical subsystem in modern battery energy storage architectures.
