摘要： A device (111) for simulating a high battery temperature used in charging a rechargeable cell (101). The device takes advantage of a control signal generated by a voltage control circuit (103) used to disconnect a rechargeable cell (101) from a charging system (105) when a predetermined voltage is reached. The device (111) is generally used with cells having a lithium based chemistry and requiring a different charging regime then nickel chemistry cells. The device (111) is activated by the control signal from control circuit (103) which detects a predetermined voltage from rechargeable cell (101) enabling thermistor (113) to change its state. This change is detected by the charging system (105) which alters its mode of operation from a rapid charging rate to a slower charging rate. The device is retrofitable to existing rechargeable batteries allowing them to be charged using existing charging systems alien to the rechargeable battery.
