The invention discloses a battery pack heating control strategy. A battery pack heating system is provided with a charging and discharging current detection device for a battery pack, a battery pack temperature detection device, a battery pack heating device and a battery pack remaining electric quantity detection device. The battery pack temperature detection device and the battery pack heating device are electrically connected with the battery pack remaining electric quantity detection device respectively, the battery pack heating device is provided with a heating controller, and the batterypack remaining electric quantity detection device is used for continuously detecting the remaining electric quantity of the battery pack; if the remaining electric quantity of the battery pack is detected to be greater than a set value, the heating operation of the battery pack heating device is decided to be turned on or turned off according to whether discharging current of a discharging windowof the battery pack is detected to be greater than rated discharging current; if the remaining electric quantity of the battery pack is detected to be smaller than or equal to the set value, the charging operation of the battery pack is turned on, and the heating operation of the battery pack heating device is turned on or turned off according to whether the charging current of the charging window is detected to be greater than slow charging current.
Description
technical field [0001] The invention relates to a battery heating technology, in particular to a lithium battery pack heating control strategy. Background technique [0002] The charging window refers to the charging current limit value allowed to charge the battery under different temperature and power conditions. Similarly, the discharge window refers to the discharge current limit value that allows the battery to discharge under different temperature and power conditions. Generally, for lithium batteries, below zero degrees Celsius, the allowable charging current is very small or even not allowed to charge, so the charging window range is narrow. When many batteries are less than 0°C and greater than or equal to minus 10°C, the allowable discharge current can still maintain the normal operation of related devices [electric vehicles, etc.], but it affects the performance of the battery pack. Temperature has a much smaller effect on the discharge window than the charge wi...
