Light Electric Vehicle Battery
2, light electric vehicle battery protection and restoration of board:
In the battery cover to allow the space, mounted a shield and repair panels, it is feasible measures. Dell Inspiron E1505 Battery, PC board functions as a built-in battery inside the micro-controller and a highly efficient instrument repair. Conservation and restoration of board main functions:
1, over-charging protection: when abnormal over-voltage charger or battery pack when a serious loss of balance, over-charging protection feature is enabled, to prevent over-charging the battery pack because the deformation caused by dehydration and even; over-discharge protection: When the battery discharge is completed, Dell Inspiron E1505 Battery, Dell GD761 Battery, Dell KD476 Battery, Dell TD347 Battery if it continues to discharge, over-discharge feature is enabled to protect the battery will not over-discharge and damage;
2, over-current protection: When the battery discharge current of more than 2C2When over-current protection feature is enabled, to prevent the battery due to excessive battery discharge caused by shortened life expectancy;
Three, short-circuit protection: to prevent accidental or man-made batteries caused by short circuit damage or cause accidents;
4, thermal runaway protection: battery pack inside the set temperature sensor and regulating the temperature change requires restrictions on the maximum charging voltage and temperature to reach thermal runaway must stop charging the above requirements.
5, pulse equalization circuit: the use of appropriate low-voltage positive pulse to prevent overcharging of the cell under the premise of a balanced battery pack;
Pulse restoration circuit: When the battery capacity decreased gradually after the formation of lead sulfate,Dell GD761 Battery, the appropriate pulse allows the battery capacity has been a very substantial recovery.
6, hot fix pattern: When the battery is a serious salinization, charging voltage can not increase, when the charger can not be converted to float, repair plate to enable hot fix model that allows the battery temperature rises to 50 ℃ for pulse, well the elimination of sulfide to achieve restoration goals.
Lithium-ion batteries are to protect plate, lead-acid batteries do not need to protect the board why? Is not no need, because lead-acid battery of the current, voltage is high, the protection board technical difficulties, cost, difficult to control.
Following the successful development of Xiamen, China-day WATA-A9 conservation and restoration of the main parameters and principles board for the industry, technology developers refer to: WATA-A91-4 Jie electric vehicle battery protection, restoration panel W-4812 SeriesW-4812 series built-in IC and high-power high-precision low resistance CMOS. On the whole process of charging and discharging battery current, voltage, temperature monitoring. The protection board has over charge protection, over-discharge protection, thermal runaway protection, discharge over-current protection, short circuit protection, pulse restoration, hot repair.
