Battery manufacturers specify recommended float and equalize voltages at 25 °C (77 °F) for their product. In order to prolong battery life and ensure reliable operation, temperatures above or below the nominal 25 °C require a slightly lower or higher voltages (respectively). The Battery Temperature Compensation (or TempCo) feature for ATevo automatically adjusts the charger’s dc output voltage, based upon battery temperature. The external battery probe allows ATevo to provide:
- voltage compensation based on battery temperature
- battery temperature value (°C) monitoring
- a battery overtemp alarm
The ATevo TempCo option (ordering p/n EJ5304-##) consists of a bagged kit, including a Battery Temperature Probe (A10), and a signal cable to connect the probe to the ATevo. The A10 probe contains a temperature-dependent resistor in an epoxy module. For mounting, the epoxy is housed within a tin-plated crimped ring lug. The probe is installed on (or near) the battery. The TempCo option can be purchased with ATevo, or field installed later.
The bagged TempCo accessory also contains a separate user Installation & Operating Instructions (p/n JA5015-51). An abbreviated version of that text is listed in the following sections.
