Acuity Battery Monitoring System

DESCRIPTION The Curtis Acuity® Battery Monitoring System is a device that mounts directly to an industrial vehicle lead acid battery. It measures, records and transmits battery performance data throughout the battery’s life. APPLICATION Curtis Acuity is ideal for use in electric vehicles for material handling, airport ground support, floor cleaning, light-on-road, golf/utility and aerial work platforms. FEATURES • Highly accurate State-of-Charge calculation that uses battery voltage, current, temperature and time to maximize vehicle up-time. • Acuity provides the data to determine if the battery has been operated within the conditions of its warranty. • Because Acuity is permanently attached to the battery, information is collected consistently and accurately no matter when or how often the battery is moved, without interruption. • The data from Acuity allows the optimization of a battery fleet to ensure that vehicle productivity is maximized. • Acuity data is communicated via CAN bus, which allows easy integration with Curtis enGage displays, motor controllers and hand-held programmers. • Installation of Acuity is simple and non-invasive to minimize cost and the need for special hardware. No cutting of cables or drilling into the battery. • Integral Real-Time-Clock allows date and time stamping of significant events related to the battery or any vehicle component on the CAN bus. • By measuring, recording and communicating battery current, voltage, temperature and use-time, Acuity can compensate for the effects of variations in load, duty cycle and operating temperature of any given application. • Acuity calculates the percent of Rated Capacity remaining in the battery as an indication of remaining battery life. • Curtis Acu-Set software, when installed on a computer that is connected to an Acuity via a CAN-to-USB dongle, allows: Acuity to be configured to match the specific battery on which it is mounted. Historical data from Acuity to be uploaded a PC. Instantaneous battery performance data to be viewed on a PC (Power Prover mode). Recording of battery data for a user-specified period of time or specific vehicle operation.
