Renault Zoe Battery Pack
The Renault Zoe used three variants of Battery
- Ph1 Zoe - 22kWh
- Ph1 Zoe - 41kWh
- Ph2 Zoe - 52kWh (Including a software locked to 41kWh variant)
All three variants use 2p96s configuration, for 360v nominal.
22 & 41kWh variants either came with 22kW AC charging, or 43kW AC charging (Q90/Q210 motor) using a system Renault names the Chameleon Charger, presumably due to the ability to operate over a wide range of charge current, and on either single or three phase power. This system also uses the motor stator winding as an inductor.
The BMS's, regardless of motor variant are designed with 43kW maximum charge rate in mind, and the most the BMS will ever show as "Input Possible" is 43kW. Interestingly this was never possible, due to the losses in on board AC-DC conversion (~10%).
52kWh variants either came with 22kW AC charging alone, or alongside CCS charging.
Phase 1 22kWh Battery Pack
2012 - 2016 Manufactured by LGChem
Phase 1 41kWh Battery Pack
2016 - 2019 Manufactured by LGChem, same dimensions as the 22kWh pack and a straightforward bolt-in swap to earlier cars.
Phase 2 52kWh Battery Pack
2019 - 2024 (end of Zoe production) similar dimensions to the previous two batteries, but with an additional 4 mounting bolts, and bolts directly to the chassis as opposed to via metal brackets. Can be bolted into original Zoe chassis if you add a plate with two captive nuts inside the chassis rail. Totally different pin configuration on the low voltage connector, and totally different CAN messages so requires a CAN translator. High Voltage connector is the same as the earlier models, wired the same.
