FAQs 6

Does preheating affect battery performance?

In self-heating systems, a larger preheating current may result in overdischarge of the battery pack and damage the battery. Since this system can achieve a high heating rate using a relatively small current, it hardly damages the batteries. 3.2. Influence of the preheating system on battery performance 3.2.1.

Why do EVs need a preheating system?

Preheating systems can rapidly heat the vehicle's interior and the battery to restore its charge/discharge performance, allowing the vehicles to operate at low temperatures. For EVs, an efficient preheating system must be flexible and convenient that can preheat the battery at anytime and anywhere.

How much energy can a battery preheat safely?

The system can preheat the battery safely in the capacity range of 20%–100%. When the battery pack is set in −20 °C, the effective electric energy can be increased by 550% after preheating. An energy conversion model is also built to measure the relationship between the energy improvement of battery and the energy consumption by preheating.

How does a CPCM preheat a battery?

The cPCM wraps the battery and transfers the heat to the battery through conduction. Thus, the cPCM acts as an external resistance and generates heat to preheat the battery from the outside, whereas the internal resistance of the battery generates heat to preheat the battery from inside.

Can CPCM based thermal management system preheat batteries at low temperatures?

Full-temperature thermal management test In order to prove that the cPCM based thermal management system can preheat the batteries at low temperatures and cool the batteries at high temperatures, the battery pack with and without cPCM were test under −10 °C.

What is a self preheating system?

This self-preheating system shows a high heating rate of 17.14 °C/min and excellent temperature uniformity (temperature difference of 3.58 °C). The system can preheat the battery safely in the capacity range of 20%–100%. When the battery pack is set in −20 °C, the effective electric energy can be increased by 550% after preheating.
