Battery Cell Voltage Generator, a 12-channel generator and measuring instrument designed to deliver easy and accurate evaluation of battery management systems (BMS) for lithium-ion battery (LiB) packs used in electric vehicles and storage batteries.
A BMS is an electronic system that manages a rechargeable battery cell or battery pack for the purpose of managing the output, charging and discharging and provide notifications on the status of the battery pack to the electronic device. The most important goal of a BMS is to provide critical safeguards to protect the batteries from damage by measuring and reporting critical information for the operation of the battery. Lithium-ion batteries, in particular, need a BMS to maintain their charge and discharge level – overcharging them can lead to damage, overheating and even explosion. Another function of a BMS is to prolong the life of a battery – excessive discharge can permanently reduce overall capacity.
The new SS7081-50 acts as a simulated battery and provides voltage generation to efficiently build a test environment that might otherwise be difficult to recreate using actual batteries, power supplies and electronic loads so that users can effectively evaluate BMS performance and safety characteristics. As electrification of the automobile and use of LiB continue to skyrocket, R&D of the systems used to manage the batteries has also accelerated. The SS7081-50 contributes to more effective and accurate evaluation of those systems by delivering the following:
