Zusammenfassung: | In order to improve the energy efficiency of pure electric vehicles, the
author proposes a thermal energy recovery and automation monitoring system
for motor equipment based on new energy vehicles. Based on the analysis of
the battery thermal management model, a series heat exchange model between
the motor and the battery was established. An integrated thermal management
system control strategy based on motor waste heat recovery was proposed for
electric vehicles in low temperature environments, and simulation and
validation were conducted at different environmental temperatures (-10~0 ?).
The simulation results show that this configuration can shorten the heating
time by 111-343 seconds compared to traditional battery thermal management
systems during the heating stage. During the insulation stage, frequent
activation of positive temperature coefficient thermistor can be avoided
and the battery temperature can be maintained around 20?C, which is not only
conducive to extending the battery life but also reduces the comprehensive
energy consumption by 4.39-7.70%. On the other hand, this configuration can
reduce the impact of low temperature on comprehensive energy consumption
from 9.77-2.07%. It is proved that heat recovery can effectively alleviate
the range anxiety caused by ambient temperature. |
