description The invention discloses a thermal runaway early warning system for a lithium ion battery of a new energy automobile. The system comprises: an electric signal monitoring unit used for monitoring an electric signal, a temperature monitoring unit used for monitoring a temperature signal, a microprocessor used for sampling and collecting the electric signal and the temperature signal, judging the state of the lithium ion battery and sending out a corresponding control instruction, a controller which is used for receiving the control instruction; and the alarm which is used for giving an alarm. The invention further provides a new energy automobile lithium ion battery thermal runaway early warning method. The thermal runaway early warning system has the beneficial effects that the charging and discharging electric signals and the battery temperature of the lithium ion battery can be monitored, the thermal runaway phenomenon of the lithium battery under different conditions can be judged and identified, early warni
