Battery Management Solution

Battery monitoring solution for automotive applications

InnovationLab (Heidelberg, Germany) has launched BaMoS, its battery monitoring solution for automotive applications. BaMoS uses ultra-thin printed pressure and temperature sensors to capture detailed battery data down to the individual cell level, which can be used to extend battery lifetime by up to 40 percent. The system captures detailed, cell-level pressure and temperature data, obtained from ultra-thin printed sensor foils which can be placed between individual battery cells. As battery cells expand and contract during the charge-discharge cycle, a pressure-sensitive foil can monitor this ‘breathing’, to measure the state of charge, detect any irregular behavior, and prevent overcharging.This cell-level information delivers valuable insights into state of health and performance, helping R&D teams to improve their battery designs and battery monitoring solutions.

Automotive Relays

Automotive relays - low current up 80amps

CIT Relay & Switch (Minneapolis, MN) offers automotive relays from low current up to our highest switching capacity of 80amps with voltage ranging from 6VDC to 72VDC. PC pin and quick connect mounting methods offer multiple choices for the design engineer, along with the option of mounting tabs in plastic and metal. Automotive relays can be found in just about every car, truck, tractor, bus, golf carts, and more. Used to enable a low amperage circuit to switch on and off a higher amperage circuit like headlights, relays are also used to switch multiple things at the same time using one output. A single output connected to multiple relays allow opening and/or closing simultaneously. CIT also offers automotive relays with a shroud option and sockets for mounting solutions.

Communication Gateways

SG (Smart Grid) communication gateways

Battery Energy Storage Systems require communication capabilities to connect to batteries and peripheral components, communicate with the power grid, monitor systems remotely, and much more. Intelligent networking is also required in order to connect to cloud solutions or SCADA systems. This connection can be made by using SG (Smart Grid) gateways from HMS Industrial Networks Inc. (Bedford, NH) that support both energy and industrial fieldbus protocols, as well as protocols required for cloud connection. The SG gateways enable centralized control as well as remote access for predictive maintenance, logging or data visualization using the i4SCADA solution from the HMS-owned company WEBfactory. The SG gateways also provide robust cybersecurity features, such as firewall, OpenVPN, TLS encryption and user management.
