Honda Clarity was pushed in the PHEV model in 2018. The battery system uses the PHEV2NCM square battery. The battery system is 17kWh, the pure battery life (JC08 working condition) 114.6km, the highest speed of 160km / h in the pure electric mode.
Honda Clarity was pushed out of the Phev model in 2018, let's simply understand the battery system.
▼ Clarity family
ClarityEv, FCV and PHEV are based on the same platform development, and let's take a brief look at the PHEV model battery system.
Battery module, the module upper cover reserved the signal line card bit.
The battery system uses the Phev2ncm square battery, capacity 27.3ah, battery cell size 148.7 * 26.7 * 91.1mm, battery system total power is 17kWh, pure battery life mileage (JC08 working condition) 114.6km, pure electric mode up to 160km / h. The entire battery system consists of 14 modules, each of which is composed of 12 cells, a combination of 2P6S, a total of 168 cells, a total of 2P84S (310.8V, 54AH).
Let's take a look at the Accordphev battery pack of 6.7 degrees. Some simple contrasts later.
Accordphev battery pack:
Still returning to the Clarityphev battery pack,
Battery system overall picture:
Battery system internal structural diagram, you can see that 14 2P6S modules are connected in series, and 6 modules in the first tail.
The entire IPU system consists of 12VDC-DC converter, ECU and battery system. The battery system is 17 degrees, compared to Accordphev, performance has improved, and the output capability is 1.4 times that of Accordphev. In addition, the module design is also re-decreasing the entire module height, and the electrical connection has also been researched. In addition, the entire system uses a liquid-cooled heat-cooling method, and passes through the bottom of the module and the liquid cooling plate, and the battery heat passes the battery through the cold sheet. go. Compared to air cooling, it is possible to ensure higher battery cooling performance on an aspect, and on the other hand can effectively utilize space.
Let's take a look at the local cold plate, the bottom of the battery module is tightly bonded to the cold plate, and the heat generated by the battery module is conducted to the cold plate wall through the thermal interface material, and then heats heat through the cooling liquid inside the cold plate. Take away, discharged to the air through the radiator.
In the figure, we can see that the battery system, 12VDC-DC and charger share a liquid cooling system, and the coolant flows through the battery system inside the battery system to the charger and 12VDC-DC circuit, and during charging, if the battery The temperature is in a suitable range, and the coolant can be switched through the three-way valve, and the battery is not cooled.
Battery system structure diagram, the entire layout is comparison.
Coldboard flow distribution
Let's take a look at the charging interface.
The whole vehicle is worth seeing the VCU integrated PCU, internal integration VCU and inverter.
Ok, let's introduce so much as a reference. , Read the full article, original text title: [Jierui Air • Total Notes] Attached Honda Clarity Phev Power Battery System
