Proper Voltage ist ein B2B-Technologieunternehmen, das ein Battery Operating System (bOS) bereitstellt – eine Kontrollschicht und Softwareplattform, die fortschrittliche Batterietechnologien mit realen Produktsystemen verbindet. Die Plattform ermöglicht es, dass Produkt- und Batteriehersteller neue Batterietechnologien sicher einführen können, ohne Hardware-Neugestaltung oder Neuzertifizierung, und optimiert so den Energieverbrauch, die Sicherheit und die Geschwindigkeit der Inbetriebnahme. Proper Voltage konzentriert sich auf die Integration verschiedener Batterietechnologien, die Vereinfachung von Zertifizierungs- und Integrationszyklen sowie die Bereitstellung softwaregesteuerter Energiemanagement- und Überwachungslösungen für kommerzielle und industrielle Produkte.
