Under Voltage Protection (UVP) Technology
Electrochem’s proprietary Under Voltage Protection (UVP) Technology is a control that can be added to individual cells or a battery pack to prevent over discharge. The device monitors the voltage of a cell or group of cells, and then disconnects it from the load if it senses the voltage drops below a minimum voltage limit. This protection can be applied to an entire pack, a string of cells, or each individual cell. The voltage limit can then be adjusted accordingly.
Operation Features
Reduced Internal Pressures
Over discharging a battery creates higher internal pressures, increasing the chance that a cell may vent. Our proprietary UVP technology prevents discharging when voltage drops below an acceptable limit, reducing the chance of a costly, possibly dangerous, situation.
Prevention of Voltage Reversal
If the discharge of a cell in series is stopped when it reaches a minimum threshold, it will eliminate the risk of that cell being driven into voltage reversal from the other cells connected in series. This further decreases the chances that a cell may vent.
No Impact to Runtime
The majority of applications require a minimum voltage to power electrical components. Any capacity beyond that limit is often unused. Furthermore, the capacity obtained from discharging a cell beyond that limit is insignificant; meaning there’s minimal capacity to be gained running to 0V. Therefore, in the majority of applications, capacity and runtime are not significantly impacted.
