JAECOO 7 PHEV: Longer charging time in cold conditions and battery heating
Charging is slower in cold conditions, and battery heating increases energy consumption.
JAECOO 7 PHEV: Longer charging time in cold conditions and battery heating
Symptoms
- Charging is slower in cold conditions, and battery heating increases energy consumption. [1]
Possible causes
- The manual explains that excessively low or high temperatures affect charging performance; thermal management heating in cold conditions extends charging time. [1]
Checks
- Check the temperature and charging conditions; check for ice on the charging port or connector. Do not force the port open or pull out the connector by force. [1]
What to do
- The manual recommends a heated indoor environment in cold conditions, or charging promptly after driving; use a shaded, ventilated location in hot conditions. Refer persistent abnormalities to a service centre. [1]
Applicability and limits
- Source limits: JAECOO 7 PHEV, model year unconfirmed, UK; this is a temperature protection phenomenon. Do not invent temperature thresholds or charging power values. For inspection guidance only; related parts do not constitute a recommendation to replace them. No vehicle model is linked; do not assume applicability to other models of the same brand. Scope: unknown [1]
