High-Voltage battery:The Key to Energy Storage

For the first time, researchers who explore the physical and chemical properties of electrical energy storage have found a new way to improve lithium-ion batteries. As the use of power has evolved, industry personnel now need to learn about power systems that operate over 100 volts as they are becoming more common in many types of occupancies.This improved lithium-ion battery could make longer journeys in electric vehicles possible and lead to the creation of a new generation of home energy storage, both with improved fire safety.

Our 380V high-voltage lithium-ion battery packs can be connected in series to meet 700V applications. For medium and heavy duty commercial applications ABS offers a 380V 100 kWh solution.The mass-market use of high-voltage batteries is just beginning.

Why do you need High-Voltage Batteries?

High-voltage batteries have high energy density and high discharge platforms. They can also deliver more capacity under the same conditions of use, so their battery life is longer while delivering more power. Under normal circumstances, the lifetime of OSM’s high-voltage batteries will increase by 15-25%.

Below is a summary of the benefits of using our high-voltage batteries:

*High energy density and longer battery life: 15% higher than ordinary batteries;

*High and stable discharge platform: Frequent use does not affect the battery life as much as ordinary batteries’;

*The batteries can still provide 80% of its original capacity;

*Based on real-life applications, operate under high and low temperatures, and meet different rate requirements of the power industry;

Applications of High Voltage Batteries

It is Widely used in commercial buildings, industrial fields and power grid side.

High-voltage system BMS

What are they?

High-voltage battery management systems or BMS are an integral part of any battery system. They control how the battery functions and how well they perform under various conditions.

Why do we need them?

High-voltage batteries have complex chemistries which need to be monitored and maintained. This is critical that these battery systems stay within certain limits, to ensure they are not damaged or destroyed. In addition a good BMS will extend the life of you batteries by reducing oxidation and plate damage. In the long run they will always prove value for money.

How do they work?

BMS measure a range of parameters, namely voltage, current, temperature and sometimes specific gravity. They use various probes, meters and sensors to detect the conditions affecting the battery. These can include high ambient temperature, excessive current draw and over voltage. These measurements are further recorded and computed to determine state of charge and battery health providing further insight into the batteries performance.


OSM’s High-Voltage BMS provides cell- and stack-level control for battery stacks up to 380 VDC. One Stack Switchgear unit manages each stack and connects it to the DC bus of the energy storage system. Cell Interface modules in each stack connect directly to battery cells to measure cell voltages and temperatures and provide cell balancing.

For parallel stack aggregation, an additional Energy can be included in the ESS. The acts as a central control hub that combines all the Stack Switchgear units and enables the stacks to be managed as a unified battery system.

Connects and disconnects a battery stack to the DC Bus of the ESS in response to requests from system controllers. Will also report the resulting capacity change to the PCS and other energy management systems.

Will alter current limits to protect the battery from overcharge and over-discharge as well as to reduce battery temperature and to prevent over-voltage.

Utilizes a pre-charge circuit when connecting the stack to the DC bus, to prevent current surges and voltage mismatches that could damage cells.

Disconnects batteries from the power path if safety thresholds are exceeded during ESS operation.

Includes short-circuit protection.

High voltage battery system VS low voltage system

There are safety issues with current lithium-ion batteries that can damage equipment and have been known to start fires. This extra voltage in an otherwise identically sized package can mean the batteries can last longer before they need another charge.

Our approach came from a theoretical understanding of the underlying molecular structures. We predicted the safe, high-voltage properties before we experimentally verified them. So it was a very pleasant surprise indeed.
