To replace traditional fuel police vehicles,The Queensland Police Service (QPS) in Australia has purchased 400 Toyota RAV4 hybrid SUVs, and about 200 of them are currently in use.. However, an abnormality occurred during the training. Internal tests showed that under extreme conditions of frequent rapid acceleration and heavy braking cycles, the temperature of the hybrid battery rose rapidly, triggering the overheating protection mechanism.
Immediately, the vehicle entered "limp mode", the top speed dropped sharply, and the acceleration performance dropped significantly; the traction control system automatically turned off, steering accuracy was affected, and the vehicle stability was insufficient during the actual pile-circling test.
It is reported that the RAV4 hybrid uses an air-cooling-based battery heat dissipation design, which performs stably in civilian scenarios. However, the heat generated by high-intensity police operations far exceeds that of daily use, and the efficiency is insufficient.
Toyota sets strict temperature thresholds to protect battery life,Once the standard is exceeded, the power is forced to be reduced. This design is safety redundant in civilian scenarios, but it directly conflicts with police requirements.
After inspection, the Toyota Australia team stated that the vehicle was operating in compliance with the design specifications and that the overheating protection was a preset safety mechanism and was not a hardware failure, stressing that“System intervention under extreme operating conditions is intended to protect hybrid components, not vehicle defects.”
However, the police spokesman's attitude was slightly subtle.On the one hand, it admits that the problem exists and requires police officers to stop the task and cool down the vehicle when the warning light comes on; on the other hand, it insists that all models "have been rigorously evaluated and have the ability to perform police duties" and said that similar situations have not occurred in regular duty.
The purchase cost of 400 RAV4 hybrid police cars has not been disclosed, but it is estimated that the civilian version is about 35,000 Australian dollars (approximately 165,000 yuan), and the total investment may exceed 14 million Australian dollars (approximately 65 million yuan). In addition, resources such as driving training and vehicle modifications (such as police lights and communication equipment) that have been invested are at risk of being wasted.
